1). Should I buy a table saw or a radial arm saw?

	Table saws work best for ripping. Radial arm saws work best for
	crosscutting, but are limited by their arm's length. Both 
	saws will perform both tasks. The radial arm is more adaptable for 
	non-sawing tasks. For instance, overhead routing, surface planing, and 
	drum sanding attachments are available for some radial arm saws. You
	can buy a disk sanding attachment for use on most table saws.

	Ripping on the radial arm saw is difficult because it is necessary
	to push the lumber under the motor housing.  This problem can be
	minimized by use of pushsticks and holddown wheels. Maximum rip width
	is normally limited by the length of the arm. Building a secondary rip
	fence on the other side of the table from the column will enable you to
	rip wider pieces, but the off-cut piece width is then limited. Radial
	arm saws are more prone to overheating during rips in thick wood since
	the teeth stay in the cut longer, unless you cut substantially into
	the table top and even then there is no place for the sawdust to exit.

	Crosscutting on the table saw is difficult because it is tough to
	keep a board much longer than 4 ft square to the blade.  This
	problem can be minimized by building a good sliding panel cutter. Some
	table saws have built-in sliding tables, and aftermarket sliding table
	attachments are available for most saws. A couple of saws have sliding
	arbors, enabling them to work as inverted radial arm saws. The arbors
	typically don't slide as far as the length of many radial arms (for a
	review of 2 of these saws, see the April 1992 issue of FWW).

	Both saws are capable of accurate work. The radial arm saw, with its
	cantilevered arm attached to a cantilevered column, is typically less
	rigid than the table saw, which usually have their arbor trunions 
	bolted to the table in a wide pattern. Worn arm bearing in radial arm 
	saws can also contribute to wander in the cut. In table saws, play of
	the miter gauge bar will adversely affect accuracy.

	Both table saws and radial arm saws need to be aligned to work
	optimally. There are more aligning tasks to be performed on a radial
	arm saw than on a table saw. Radial arm saws typically require
	realignment more frequently than table saw, perhaps because of the 
	stresses put on the cantilevered assemblies.

	Radial arm saws don't need as much space around them as table saws for
	performing equivalent tasks. On the radial arm saw, boards are always
	oriented the same way whether you are ripping or crosscutting, so you
	need space to the left and right of the	blade, and only as wide as the
	widest board you're cutting. On the table saws, boards are oriented at 
	right angles depending on whether you're ripping or crosscutting. Thus,
	you need space in front and in back for ripping, and to the left and 
	right as well for crosscutting.

	It seems to be easier to engineer and manufacture a table saw than a
	radial arm saw, which has more moving parts that must withstand large
	forces without deflection or play. It can therefore be argued that if
	you're on a budget, a cheap table saw may work better for you than a 
	cheap radial arm saw.

	Some people say the radial arm saw is more dangerous because the blade
	is exposed above the work surface, and because the blade's location
	varies as the cut progresses. Angled crosscutting is particularly
	dangerous since the blade is now cutting where one normally holds the
	work. The spin direction of the blade tends to lift the work off of
	the table when ripping, and can pull the carriage into the work
	(resulting in binding of the saw or serious injury to a careless
	operator) in the crosscut position. So-called "safety-blades" have
	a shoulder in front of each tooth, thus limiting the amount of pull
	generated and reducing these tendencies.

	Some people say the table saw is more dangerous because you can't 
	see where the blade is like you can with the radial arm saw. On the
	other hand, the blade is always in the same spot on the table. The
	spin action of the table saw's blade tends to keep the work down on
	the table, but it can also throw the work, and off-cuts, back at the
	operator.

	Both machines are very dangerous and should be treated with much
	respect.

	As with all tool buying decisions, you should consider your intended
	applications, both now and in the future. The general consensus is that
	if you're building things like jungle gyms, house additions, or trim
	work (moldings), a radial arm saw may be best. If you're building 
	things like fine furniture or cabinets, a table saw may be more a
	more appropriate choice.

	A number of people have reported that the addition of a motorized
	miter box to a table saw is a satisfying combination.

	Taunton Press publishes a softcover book titled "Fine Woodworking on
	The Small Workshop." It contains a number of articles on designing and
	buying equipment for small shops, but is geared to furnituremaking.
	The majority of the recommendations are for getting a table saw first,
	with one writer claiming a bandsaw is the first tool to buy.

2). Which type of dado blade should I buy, the dial (wobble type) or
the stacking (chipper type)?

	The wobble type is very simple to use with infinite settings
	between approximately 1/4 inch and 13/16 inch. It does not produce
	true right angle cuts because of the design. 

	The chipper type doesn't have the same infinite setting for width.
	You can achieve nearly infinite settings by adding shims with
	thicknesses of 1/32, 1/64, 1/128, etc.  It will cut a square bottom
	on the dado, but it will also leave 2 grooves on the edges of the
	dado. The reason for this is that the blades are slightly larger
	than the chippers.  The larger blades are to reduce the splintering.
	The blades can be reground to be equal to the size of the chippers
	at the possible cost of increased splintering. Some say the grooves
	are a benefit because they provide relief for gluing joints. 

	Many people claim that the wobble type is easier to set up.

	The August 1991 Fine Woodworking further studies the features of
	the various types of dado blades.

3). How do I cut the perfect dado if both types of dado blades have
shortcomings?

	Your best bet would be to cut it with a router.

4). Should I buy a Sears blurfl?

	Most people agree that the Sears stationary power tools sold today
	aren't the same quality as the Sears tools sold 20 years ago.  
	It can be argued that if you can't afford to buy a Delta, then
	you should be looking at one of the Taiwanese clones rather than
	looking at Sears.

5). Should I buy a Taiwanese clone blurfl?

	It depends on how much money you have. If you can afford the
	Delta blurfl you should probably get it. Buyers should be
	wary that not all Taiwanese clones are quality machines. The
	general consensus is that Grizzly has good quality control.

	It should be noted that some of Delta tools are now being made
	in Taiwan. One would hope that Delta quality control is better than
	some of the cheaper imports.


6). How do I remove paint?

	There are many ways to strip paint from wood.

	Paint can be removed by scraping and/or sanding.
	Paint can be removed by using chemical paint removers.
	Paint can be removed by using heat.
	Paint can be removed by sandblasting.
	Paint can be removed by a new product known as Peel-Away.
	Rumor has it that oven cleaner also works.

	If you know of another way to remove paint please feel free to pass
	the information along. 

7). Should I use a hot melt glue gun for my next project?

	The general consensus is that hot melt glue is not adequate
	for woodworking projects. However, hot melt glue guns can
	have a place in the shop. Many people like to use them for
	tacking items together such as when building forms or jigs.

8) Where can I get plans for the New Yankee Workshop projects?

	Plans for any of Norm's projects can be ordered for $7.50 from

        (project name)
        New Yankee Workshop
        P.O. Box 645
        Bedford, MA  01730

	Videos, which include a copy of the plans, cost $24.95 plus shipping
	and handling, from 800-272-0280.  Both the address and phone number
	are given at the end of each show.

	Most of the projects from the first two seasons are in the two
	New Yankee Workshop books.  For the workbench, one important
	dimension is *not* given in the book, though it can, I think,
	be calculated.

9) What is the best woodworking magazine?

	There are many good woodworking magazines. Two that are frequently
	recommended in this group are Fine Woodworking and Woodsmith.

	Fine Woodworking is a bit on the artsy side and more for the
	experienced woodworker. It does not get into the small details
	of a project.

	Woodsmith provides much more details for projects. Woodsmith is
	well suited for both the amateur and experienced woodworker.

10) What is a board foot?

	A board foot is a common unit used in the measurement of wood.
	It is equal to 1 foot length x 1 foot width x 1 inch thick.
	It should be noted that the thickness is nominal thickness.
	After drying and surfacing the usual thickness of a 1 inch
	board is 13/16.

	A board 10 feet long x 1 foot wide x 2 inches thick would be
	equal to 20 board feet.

11) What is the correct way to handle the glue squeeze out problem?

	Use the right amount of glue.  The (obvious) danger is a glue
	starved joint.

	 Wipe off the excess glue immediately with a damp sponge or paper
	towel.  This method gets mixed reviews.  Some claim the water-glue
	mixture will soak into the wood and show up when the piece is finished.
	Others say that this is not a problem.  The effectiveness of this
	method probably depends on the type of wood and finish that are used.

	Allow the glue to harden somewhat (1/2 - 2 hrs) and then
	chisel/scrape it off.  Some recommend removing the glue after it
	begins to film over.

	Either finish the pieces ahead of time or apply paste wax.  This
	should prevent the glue from sticking.  The problem with this is
	removing the paste wax prior to finishing.

	Use a plastic drinking straw cut at 45 degrees to scoop the glue
	out of the inside corner.  As the straw fills up, it can be trimmed to
	provide a fresh surface.

12) What books should I purchase to learn about various aspects of woodworking?

	Thanks to Ken Smith (kensmith@cs.Buffalo.EDU) for providing the
	ISBN numbers along with a couple of additions to the list.

13) How do I finish toys so that they are non-toxic?

	a.  Behlens Salad Bowl Finish.  This product has been approved by
	    the FDA for use on objects that will come in contact with
	    food.  It produces a nice, semi-gloss finish.
	b.  Any vegetable oil. Could become rancid after a period of time.
	c.  Walnut oil.  It reacts with the air and hardens into a true
	    finish.  It works particularly well when the oil is heated
	    and the item is dipped into the warm oil. Available at health
	    food or large grocery stores.  Don't buy the gourmet stuff!
	d.  Mineral oil or vaseline.
	e.  Water-based polyurethanes.  These are new products which are
	    very different from the more familiar oil-based
	    polyurethanes.  They are totally non-toxic, dry quickly, and
	    have no strong odors when applying.
	f.  Pure Tung Oil. It has no driers or solvents. It is essentially
	    just a vegetable oil but produces a nice finish that won't go
	    rancid. Use only Tung Oil that is "pure".
	g.  Rumor has it that shellac is also safe once it dries. I have
	    been unable to verify this.
	h.  Leave items unfinished.

14) What size drill bit do I use for a wood screw?

  Screw Gage    Shank    Shank     Pilot     Pilot

15) How do I finish the edge of plywood?
	a) Wood tape. It comes in 2 forms, one that can be ironed on, and
	   one that can be contact cemented on. The tape is approximately
	   1 inch wide, and can be trimmed with a plane, router, or knife.
	b) Glue strips of wood, either purchased or cut from lumber.

16). Which saw blade should I buy?
	There is an excellent article on evaluating carbide tipped
	sawblades in issue #72 of Fine Homebuilding (March 1992).

	To summarize the article:

	An expensive blade will typically last longer than a cheap
	blade and the cost difference is made up by the number of
	extra sharpenings available from the investment.

	A blade that has been tensioned will run truer and cost more
	than a blade that hasn't been tensioned.

	Carbide blades will last up to 60 times longer than steel blades.

17). Where are the archives for rec.woodworking?
	There are 2 archives that I know about.

	The first is ftp.cs.purdue.edu in /pub/sjc/woodworking. Currently
	it contains a list of Woodsmith plans.

	The second is ftp.cs.rochester.edu in /pub/rec.woodworking. Currently
	it contains summaries of past discussions of tools, some
	safety related notes, and some of the FAQ postings. Below is

18). Where can I find cradle plans?

	1.  Garrett Wade
		$9.95 for plans for a "rocking cradle
		item number 14A03.SA in their 1993 tools catalog

	2.  The Woodworkers' Store
		$4.95 for plans for a "four post cradle"
		item number 40360 in their 1991-2 catalog

	3.  The August 1990 issue of Fine Woodworking has an article about
		making a cradle.

	4. Bartley offers a cradle kit for $199.  If it's up to the quality
		of their other kits, this should be good.

	5. Woodsmith issue #48 - cradle with frame and panel ends with
		arched-top panels.


19). Where can I find futon plans?

	1. TODAYS WOODWORKER JULY/AUG 1989, VOL 1 NO. 4
		Queen size futon folded in half length wise.
		Very attractive Futon sofa bed frame for queen size
		futon (possibly Swedish modern). Unfolds to make bed,
		breaks down for moving.  Elegant design with lots of
		mortise and tenon joinery.

	2. WOODWORKER'S JOURNAL NOV/DEC 1992 VOL 16 NO. 6
		"Standard" futon frame for standard 2 fold futon.
		Classic bi fold futon frame for queen size futon. The

		twin (39 x 75) and full (54 x 75).
		Plans are a large single sheet of blue print like drawings
		with associated text, construction looks reasonable and
		pictures of the finished project look good, but the plans
		are a bit intimidating

	5. Popular Woodworking SEP 1992, issue #68
		"Knock-Down Couch"
		Attractive Mission / Craftsman like design for a sturdy,
		knock-down couch. The plans are not specifically for
		futons but could be easily adapted to a single fold futon
		(might not need to be adapted).


20). Where can I get information about particle board?

	The following was provided by Stavros Macrakis (macrakis@osf.org)
	and was added to the FAQ with his permission.

	*********************************************************************
	For technical information on particleboard (PB), the National
	Particleboard Association puts out some very nice free pamphlets,
	which I summarize below.  Although they are basically addressed to
	industrial users, they cover particleboard joint techniques quite well
	for the rest of us.  Some of the facts about joints are very surprising.

	I've tried to summarize the essential information below, but you can
	also order copies from: NPA, 18928 Premiere Court, Gaithersburg,
	MD 20879.

	Specifier's Guide to PB and MDF

  	Abstract
		There are 15 ANSI grades of particleboard, with diverse
  	properties.  For instance, face screwing strength varies from 90-450
  	lb, stiffness from 80,000-500,000 psi.  Recommendations are given
  	for matching grade to use.

	Dowel Holding Strength of PB and MDF

  	Abstract
		Dowels joints are one of the cost common adhesive-based
  	furniture assembly joints.  Dowelling is a simple, inexpensive, and
  	reliable means of making butt and miter joints.  Joint strength is
  	largely determined by the holding power of the dowels.  Use good
  	quality dowels, diameter <= 0.5x the stock thickness.  The longer
  	the dowel, the greater the strength.  Holes should be 0.005"
  	oversized for edges, same as dowel on faces.  Use 60%+ solids
  	content PVA adhesive, applying glue to both dowel and hole wall,
  	with slight squeeze-out.

	Adhesive-based Corner Joints for PB and MDF

  	Abstract
		The thicker the panel, the stronger the joint.  Simple butt
  	joints' strength is limited by delamination; glue blocks or edge
  	banding help.  Dowel joints are standard, and work well; they should be
  	glued only at the dowels, NOT between edge and face (!).  Four dowels
  	for 18" are standard.  Biscuits have equivalent strength, but are
  	easier to align at assembly.  The strength of a well-made simple miter
  	joint without reinforcement (dowels, etc.) is generally comparable to
  	that of dowelled butt joints (!); dowels add little strength, but
  	splines and biscuits do.  Rabbets 1/3-1/2 the depth of the panel make
  	strong joints, but tend to split.  Dados are better, but less
  	attractive.  Rabbet and dado butt corner joints (= dado and tenon =
  	dado box corner) combine a dado on one panel and a rabbet on the other.
  	Dowelled butt joints are stronger (!).  Dovetails are excellent, but
  	require precise and time-consuming machining.  Molded polyurethane
  	joints (plastic splines) are as strong as or stronger than dowel
  	joints.

	Metal Fasteners for PB and MDF

  	Abstract
		Screws, nails, and staples are widely used.  Screws are
  	strongest.  The type of screw affects strength by only +-10% (!), but
  	PB screws are less likely to break.  Screw diameter affects strength
  	little, but screw length directly affects it.  Screw diameter should
  	not exceed 20% of stock thickness.  High internal bond strength PB
  	holds screws better.  Edge screws have half the strength of face
  	screws.  Use full-length pilot holes; shorter holes do not increase
  	strength.  Ideal tightening is 3/4 turn past flush on the face; 3/8
  	past flush on the edge.  Applying glue in the hole can increase
  	strength as much as 45%.
		Staples are used for attaching fabric, etc., and to hold glued
  	joints.
		Nails split panels, so should be >3" from a corner, and >6"
  	apart.  Ring shank nails hold better, plastic coated best.  Drive
  	them at an angle.

	Mechanically-based Corner joints for PB and MDF

  	Abstract
		Most bolt and cam joints are 20-50% weaker than dowelled joints.
  	Screw joints are comparable.  Plastic corner block units can be much
  	stronger in outward bending, but only comparably strong in inward.
  	Even when they are equally strong, mechanically-based joints are often
  	less rigid.  These systems are most useful for ready-to-assemble
  	manufactured kit furniture.

	Particle Shelf Systems (Builder's Bulletin #1)

		(not seen)


	All the above are free.  They also sell:

	Particleboard from Start to Finish $12.50

  	Abstract (theirs, I haven't seen this)
		Ten chapters (120pp) of useful information for users of PB.
  	Includes information on material handling and storage, sanding,
  	machining and tooling, laminating, wet finishing, edge treatments,
  	assembly and fastening, construction products, shelving and
  	formaldehyde.

	MDF from Start to Finish $7.50

  	Similar abstract, 42 pp.

	"Fine woodworking tools. Several stores.  They have a main catalogue, a
	couple of supplements a year, and a hardware catalogue,  Even if you
	don't understand tools at all, the main catalogue is worthwhile
	getting as a coffee table book: glossy paper and beautiful presentation.
	 It makes a wonderful read. They have everything from instrument-maker's
	to log builder's hand tools, Their bottom-of-the-line quality is quite
	servicable, and their top-of-the-line tools are Art, with accompanying
	prices.  The bottom line is: good selection, high quality, reasonable

Archive-name: woodworking/motors
Last-modified: 3/30/93

This article answers many of the frequently asked questions about electric
motors. 


Motors:

    There are many kinds of motors, but this article considers only two
    kinds used frequently in woodworking tool applications: universal AC/DC
    motors and single-phase induction motors. Universal motors have brushes
    and commutators and are used for portable tools like routers, skilsaws,
    and electric drills.  Single-phase induction motors have no brushes,
    run only on AC electrical power, and are usually found on stationary
    tools such as table saws, drill presses, planers, and jointers.
    There are exceptions to this: some stationary tools use universal
    motors.

    Horsepower:  Motor horsepower is the most misunderstood (and misused)
    electric motor rating.  Neither motor, universal or induction, produces
    usable horsepower unless it is slowed down (by applied mechanical load)
    from no-load speed.  For induction motors, this slowdown is called
    "slip", and the horsepower "developed" by a motor increases with slip
    (to a simple approximation).  This is why induction motors are
    typically rated at 3450 rpm (two pole motor) or 1750 rpm (four pole
    motor).  The rating speed allows for slip from the "synchronous"
    speeds of 3600 and 1800 rpm, respectively.  Universal motors do not
    have a synchronous speed, but have a maximum no-load speed that depends
    upon the voltage applied to the motor.

    Most motors can put out a lot more maximum horsepower than they can
    sustain continuously.  By forcing more mechanical load on the motor,
    slowdown is increased and so therefore is the output horsepower.
    Mechanically, horsepower is torque times rpm, and increasing the
    mechanical load means that the rpm is slowed slightly and the drag
    torque is increased to obtain more torque times rpm.  Electrically,
    horsepower is volts times amps, and by conservation of energy, the
    mechanical output horsepower must be balanced by electrical input
    horsepower.  Since the voltage is relatively constant, this means that
    as a motor is loaded, the input current increases.  But the electrical
    winding impedance has a resistive component, so that higher current
    means more power dissipated in the windings.  In fact, the motor
    windings heat up proportional to the square of the motor current.
    Except for specially designed motors, the current that a motor can
    sustain continuously without burning out its windings is a fraction
    of the current at maximum load.

    Unscrupulous vendors sometimes publish maximum "developed" horsepower
    to make their products seem more capable than they really are.
    Developed horsepower may be two to five times the continuous duty
    rating of a motor.  Such products should be examined to discover the
    continuous duty rating to compare with other, more conservatively
    rated products.

    When the talk is of developed horsepower, the meaning is "peak" which
    for an induction motor is typically the local peak of the torque curve
    near synchronous speed.  A typical induction motor torque curve is:

          |                                                       .
          |                                  
  Torque  |                                                        .
          |
          |
          |                                                         .
          |__________________________________________________________._
                                                                     |
          0                   RPM                              1800 or 3600


    As you can see, the curve is very steep in the operating region and in
    fact, the observed operation is typically that once you load the motor
    past the local maximum torque, the speed jumps to the corresponding
    point on the initial portion of the curve or simply stops.  The actual
    operation depends upon the shape of the curve near 0 RPM.

    The Rated HP is typically the torque level at which the motor can be run
    continuously without exceeding the temperature at which the winding
    insulation beaks down.  Since there is thermal mass involved, you can
    operate the motor at higher than rated torque for less than 100% of
    the time and not exceed this temperature if the motor is cool preceding
    the run etc. etc.  etc.

    Typically, two motors with different rated HP develop different HP in a
    ration close to the same as the difference in rating.


    The story is somewhat different for a universal motor such as is used on
    most hand held tools.  In these motors, for a given input voltage, the
    torque goes up as the speed goes down.  The more you load them, the slower
    they run until they stall, at which point their torque is a maximum.
    In this case, the developed horsepower is a the point along the torque
    curve where the speed X torque is a maximum.  As with the induction motor,
    the rated horsepower means you can run the motor there at 100% duty cycle.
    Again, you can load the motor more and it will produce more torque but you
    may only do this on a limited basis.

    The final word is heat.  If you exceed the winding insulation temperature
    rating, you will fail the insulation and ruin the motor ( or pop the
    thermal cutout if so equipped). 



    Application areas:  Universal motors are compact, have high starting
    torque, can run at high rpm, and deal well with rapidly varying
    loads.  They are often used with triac or thyristor speed controls.
    This makes them ideal for portable power tools.  Single-phase
    induction motors are efficient, have a limited rpm selection,
    are relatively heavy and bulky, and are almost maintenance-free.
    They work well in stationary tools that run at one rpm or that have
    a variable-speed transmission.

    Voltage: Both kinds of motors are supplied in popular mains voltages
    (115 or 230) but only induction motors are supplied with winding
    taps that allow either voltage to be selected.  As far as the motor
    is concerned, there is no difference in efficiency when selecting
    either 115 or 230 volts.  This is because such motors have two
    identical sets of windings that are connected in parallel for the lower
    voltage and in series for the higher.  Neither connection results
    in the individual windings seeing a different voltage.  However,
    inadequate wiring can make a difference to motor operation, because
    higher current at 115 volts may give unacceptable wiring voltage drops
    in some shops or garages.  Some wiring voltage drop is expected and
    built into the motor rating.  Nominal pole transformer output (to
    your house) is about 120/240 volts.  Motors are rated for 115/230
    volt operation, which allows for 5/10 volts wiring voltage drop.
    More voltage drop than this can cause low starting torque and
    overheating at rated load.

    115 or 230 volt operation makes no difference to your power company
    either.  The watt-hour meter at your electrical entry measures watts
    regardless of the voltage used.  Your power company does not give
    you a single watt for free, and your PUC (Public Utility Commission)
    won't let the power company charge more than the legal rates.
    Watt-hour meter accuracy is a matter of law in most States.

    Current:  Motors have a nominal current rating which is supposed to be
    the current at rated horsepower and rated voltage.  A motor will not
    draw exactly rated current except in the unlikely circumstance that
    the voltage applied is exactly the rated voltage and the load applied
    is exactly the rated horsepower.  As a matter of fact, most woodworking
    tools spend much of their life spinning without applied load and drawing
    only a small fraction of nameplate rated current.  When the tool begins
    to cut, motor current varies widely depending upon cutting load.  In
    some tools which have relatively small motors, motor current may approach
    several times rated current as the tool is momentarily loaded close
    to stall or breakdown torque.  An exception to this wide variation
    would be something like the motor driving the fan on a dust
    collection system; such motors operate at about rated horsepower all
    the time because the fan presents a constant load.

    For both universal and single-phase induction motors, the full-load
    current is given by

        I  =  (746 * hp) / (eff * pf * voltage)

    where eff is efficiency, pf is power factor, and the others are
    obvious.  In AC systems, the voltage and current waveforms are
    (nominally) sine waves and may differ in phase from each other
    by an angle called the phase angle.  There are 360 phase angle
    degrees in one sinusoidal cycle.  Power factor is the cosine of
    the phase angle, and for motors this angle is normally between
    zero and 90 degrees, current lagging voltage.  In DC systems,
    there is no phase angle, and power factor is defined as 1.0.

    Typical values for single-phase induction motors running at 115
    volts AC are pf = 0.8 and eff = 0.9.  This gives a rule-of-thumb
    value for amps/horsepower at 115 volts of

          9 amps / horsepower

    This figure is probably OK for rule-of-thumb comparison of induction
    and universal motors or reasonability checks as long as you
    remember that it is based on typical values.

    If you are contemplating operating a 115 volt universal motor
    on DC, performance should be slightly better at 115 volts DC
    than it was on AC.  The proper voltage to use is 115 volts DC.
    This is because AC voltages are given as RMS values, which
    are their power-equivalent DC values.  The tool will actually
    endure less voltage stress under DC operation because the
    peak voltage experienced under DC is 0.707 times the AC peak
    voltage.  Switches and contacts, however, may not last as long.

    Starting current can be as much as ten times rated motor current.
    This is usually not a problem for the circuit breaker feeding the
    motor, because modern circuit breakers are typically rated to trip
    instantaneously at about ten times breaker nameplate rating.  For
    currents less than the instantaneous value, the breaker trips due
    to internal heater elements which mimic the heatup characteristics
    of the wiring the breaker is supposed to protect.  Since starting
    currents last only a second or two (unless the motor is jammed),
    motors usually will not trip circuit breakers on starting current if
    the breaker is rated at higher current than the motor nameplate
    current.  This may not be true if you start the motor on a circuit
    which is already loaded close to rating.

    A motor may trip your circuit breaker on time-overcurrent (the
    heaters) even if the motor nameplate current rating appears to be
    within the breaker rating.  This can happen if you continuously
    overload the motor; motor current will then be several times the
    nameplate rating.  There may be other signs of this.  The motor may
    become extremely hot (spit sizzles on the casing).  This is General
    Electric's way of telling you to slow down.

    Breakdown torque:  Single-phase induction motors, unless they are
    designed for torquemotor operation, have a "breakdown" torque rating.
    This refers to the motor torque-versus-rpm curve, which has a peak
    torque somewhere between zero rpm and rated rpm.  If the motor is
    running and load is applied, the motor slows and torque increases
    until breakdown torque is reached.  At this point, further rpm
    reduction causes a reduction of motor-supplied torque, and the motor
    rpm reduces rapidly to zero (it "breaks down").  This is why a saw,
    for instance, appears to suddenly stall as it is overloaded.

    Ventilation: Most motors have one of two kinds of ventilation: fan-
    cooled open housing, or totally enclosed, fan-cooled (TEFC) housing.
    In the former type, a fan attached to the motor shaft draws air
    through the internal parts of the motor and blows it out of
    ventilation slots cut into the motor housing.  Most universal motors
    are of this type because of the need to cool the brushes and to
    exhaust brush carbon dust and commutator copper fragments.  In the
    TEFC type, the motor housing is completely enclosed and no air
    gets to the internal parts of the motor.  Instead, internal heat
    is conducted through the metal housing to fins, where air blown
    by an external fan removes the heat.  Some induction motors have
    this kind of (more expensive) ventilation and they are often used
    in applications where excessive dust or flammable conditions exist.

    Drive gear:  Surprisingly enough, even though many people will look
    at motor horsepower rating, they often completely ignore the drive
    gear attaching the motor to its load.  The drive gear is often a clue
    to the real power rating of the motor-drive combination.  It's
    difficult to determine the rating of enclosed gears, but v-belts
    can give an immediate visual clue.  While larger pulleys increase
    a v-belt rating, a nominal rule of thumb is about one horsepower
    per 1/2 inch v-belt.  Two 5/8 v-belts on large pulleys may be good
    for 4 or 5 horsepower.  One small belt on a motor which "develops"
    3 horsepower is cause for some suspicion.  Actual belt drive ratings
    can be found in manufacturers handbooks (see Gates, for example) or
    in Machinery's Handbook.

    Motor Starters:  Motor starters are big relays mounted in expensive
    metal boxes with heater overloads matched to the motor they start.
    They serve two purposes: 1) The relay contacts are heavy duty and
    are rated for the motor starting current.  Delicate contacts, such
    as those on a pressure switch, will fail if used directly to
    start a large motor.  Delicate contacts are therefore wired to
    operate the motor starter relay rather than the motor.  2)  Wall-
    mounted circuit breakers are designed to protect building wiring,
    not motors plugged into wall receptacles.  If your electrical box
    circuit breaker trips before your motor burns up, it is incidental,
    not on purpose.  However, motor starters are designed to trip on
    heater overload before the motor they start burns up.

    How much horsepower:  This question is often asked and has no easy
    answer.  This is because the amount of horsepower you need depends
    upon your patience, your preferences, and the way you use the
    machine in question.  Here are some pros and cons.  A larger
    horsepower motor (and associated drive gear) has a thicker shaft
    and is typically more robust than a smaller horsepower motor.  It
    responds to overloads and hard cuts more strongly, and may not stall
    in your application.  It does not use very much more power, since
    electric motors use only power demanded plus some motor losses (which
    are somewhat larger for higher rated motors).  On the down side, the
    initial expense of the motor and drive gear is greater.  Higher
    horsepower often requires 230 volt wiring.  The motor and associated
    drive gear and mountings are heavier.  A smaller horsepower motor
    is cheaper, lighter, and may run on 115 volts.  For a careful worker,
    the torque supplied may be sufficient.  On the down side, the tool
    may stall more often and wet wood may be impossible to cut.  The
    drive gear may be less robust and may require more maintenance.  If
    the tool is operated in overload, the 115 volt circuit breaker may
    trip.

Here's a little utility for the robotic woodcarver, rtword v1.0.  It reads a 
font file (small example included) and creates an input file for the 
stepper.exe provided by Andrew Cilia.  The combination of these two programs 
should allow you to generate name plates, and more, based on characters in the
font file.  The font file is a simple ascii file with with relative coordinates
defining each character.

Comments/suggestions welcome.
Thanks and Enjoy.
Dave

Over the weekend, I learned something about old wiring that others
may be as ignorant about as I was on Friday:

Sometimes, the light switch cuts off the white (neutral) wire instead
of the black (hot) wire.  This means that you can create a grounded
circuit even if the switch is off, by connecting the black (or, in an
old house, slightly darker grey) wire to something grounded, using 
any conductive material.

Yes, theconductive material in this case was me.  I have no idea what
the grounded object was.

I now have more time for woodworking, since my wife isn't going to ask
me to do little electric jobs for a while.

The neutral wire is never switched. If yours is, the job was done incorrectly.
It has nothing to do with age.  Furthermore, (this is your mom speaking) 
always turn off the circuit breaker (pull the fuse) before working on the 
wiring! 

Neutral wires are ground referenced at the breaker box (tied to ground) so
the hot wire (black) and a good ground will toast you as well as the hot and 
neutral.

In a previous article, katp@alvin.mcnc.org (kathleen pitts) says:

>HELP!  We're looking for plans to build a futon (either bi- or triforld).
>Can anyone help?

Heh Kathleen.

Can't help directly, maybe indirectly.  I have made three or four.
Each one was different, never had a plan.  Each was for a different
person who had seen one in a shop they liked.  Sp I went to the
shop and sized it up mentally and regonkulated the math.  You just
adjust the height and dimensions to suit your needs.  The easiest
way I found for the hinge was a sawed off one inch wooden dowel cut
into about four inch lengths.  When in this supports the backrest,
when out it allows the frame to open to a bed.  Was the futon a
single, double, queen or king?

Take care.

I have a store-bought hardwood bunkbed set which knocks down fairly easily and
is quite rigid when assembled.  The long side rails are fastened to the 
end posts with flat-head allen bolts into barrel nuts.  

Forgive the ASCII-hack, but here's a cross-section:

On my unit there are actually 2 bolts on each end of each rail, and they 
look to be 6mm diameter.  There's a loose dowel inside there also, between 
the two bolts, which helps alignment and facilitates assembly.

The steel barrel nuts insert from the inside of the rails into blind holes,
so the only visible parts are the bolt heads, but they are fairly attractive
and quite flush to the surface.  Of course the bolt heads could be recessed
and covered with wooden plugs, but that would complicate the knock-down-ability
of the unit.  I've seen hardware like this in at least one hardware store
lately, but I don't know offhand of a mail-order source.

The wooden parts are of a light-colored asian hardwood apparently comparable
to oak in strength and hardness.   The beds remain very solid even after having
been moved several times, each time involving complete disassembly and
reassembly.  It is necessary to re-tighten all the bolts a few weeks after the
initial assembly, then the whole thing seems to remain quite secure for a
long time.  It knocks down very easily (I use ball-head screwdriver-type hex
drivers) but it's necessary to secure the barrel nuts to avoid losing them in
transit (usually they're hard to get out, but Murphy's law dictates that at
least one will fall out and get lost, so I tape over the holes whenever I
move the thing).

All in all I think it's a fairly practical design.

I saw an ad in the newspaper for futon platform plans.
The photo showed a platform that folds in half to form a sofa.
It's made from Douglas fir and pine, and can be made in twin, full
or queen sizes.

1). Should I buy a table saw or a radial arm saw?

	Table saws work best for ripping. Radial arm saws work best for
	crosscutting, but are limited by their arm's length. Both 
	saws will perform both tasks. The radial arm is more adaptable for 
	non-sawing tasks. For instance, overhead routing, surface planing, and 
	drum sanding attachments are available for some radial arm saws. You
	can buy a disk sanding attachment for use on most table saws.

	Ripping on the radial arm saw is difficult because it is necessary
	to push the lumber under the motor housing.  This problem can be
	minimized by use of pushsticks and holddown wheels. Maximum rip width
	is normally limited by the length of the arm. Building a secondary rip
	fence on the other side of the table from the column will enable you to
	rip wider pieces, but the off-cut piece width is then limited. Radial
	arm saws are more prone to overheating during rips in thick wood since
	the teeth stay in the cut longer, unless you cut substantially into
	the table top and even then there is no place for the sawdust to exit.

	Crosscutting on the table saw is difficult because it is tough to
	keep a board much longer than 4 ft square to the blade.  This
	problem can be minimized by building a good sliding panel cutter. Some
	table saws have built-in sliding tables, and aftermarket sliding table
	attachments are available for most saws. A couple of saws have sliding
	arbors, enabling them to work as inverted radial arm saws. The arbors
	typically don't slide as far as the length of many radial arms (for a
	review of 2 of these saws, see the April 1992 issue of FWW).

	Both saws are capable of accurate work. The radial arm saw, with its
	cantilevered arm attached to a cantilevered column, is typically less
	rigid than the table saw, which usually have their arbor trunions 
	bolted to the table in a wide pattern. Worn arm bearing in radial arm 
	saws can also contribute to wander in the cut. In table saws, play of
	the miter gauge bar will adversely affect accuracy.

	Both table saws and radial arm saws need to be aligned to work
	optimally. There are more aligning tasks to be performed on a radial
	arm saw than on a table saw. Radial arm saws typically require
	realignment more frequently than table saw, perhaps because of the 
	stresses put on the cantilevered assemblies.

	Radial arm saws don't need as much space around them as table saws for
	performing equivalent tasks. On the radial arm saw, boards are always
	oriented the same way whether you are ripping or crosscutting, so you
	need space to the left and right of the	blade, and only as wide as the
	widest board you're cutting. On the table saws, boards are oriented at 
	right angles depending on whether you're ripping or crosscutting. Thus,
	you need space in front and in back for ripping, and to the left and 
	right as well for crosscutting.

	It seems to be easier to engineer and manufacture a table saw than a
	radial arm saw, which has more moving parts that must withstand large
	forces without deflection or play. It can therefore be argued that if
	you're on a budget, a cheap table saw may work better for you than a 
	cheap radial arm saw.

	Some people say the radial arm saw is more dangerous because the blade
	is exposed above the work surface, and because the blade's location
	varies as the cut progresses. Angled crosscutting is particularly
	dangerous since the blade is now cutting where one normally holds the
	work. The spin direction of the blade tends to lift the work off of
	the table when ripping, and can pull the carriage into the work
	(resulting in binding of the saw or serious injury to a careless
	operator) in the crosscut position. So-called "safety-blades" have
	a shoulder in front of each tooth, thus limiting the amount of pull
	generated and reducing these tendencies.

	Some people say the table saw is more dangerous because you can't 
	see where the blade is like you can with the radial arm saw. On the
	other hand, the blade is always in the same spot on the table. The
	spin action of the table saw's blade tends to keep the work down on
	the table, but it can also throw the work, and off-cuts, back at the
	operator.

	Both machines are very dangerous and should be treated with much
	respect.

	As with all tool buying decisions, you should consider your intended
	applications, both now and in the future. The general consensus is that
	if you're building things like jungle gyms, house additions, or trim
	work (moldings), a radial arm saw may be best. If you're building 
	things like fine furniture or cabinets, a table saw may be more a
	more appropriate choice.

	A number of people have reported that the addition of a motorized
	miter box to a table saw is a satisfying combination.

	Taunton Press publishes a softcover book titled "Fine Woodworking on
	The Small Workshop." It contains a number of articles on designing and
	buying equipment for small shops, but is geared to furnituremaking.
	The majority of the recommendations are for getting a table saw first,
	with one writer claiming a bandsaw is the first tool to buy.

2). Which type of dado blade should I buy, the dial (wobble type) or
the stacking (chipper type)?

	The wobble type is very simple to use with infinite settings
	between approximately 1/4 inch and 13/16 inch. It does not produce
	true right angle cuts because of the design. 

	The chipper type doesn't have the same infinite setting for width.
	You can achieve nearly infinite settings by adding shims with
	thicknesses of 1/32, 1/64, 1/128, etc.  It will cut a square bottom
	on the dado, but it will also leave 2 grooves on the edges of the
	dado. The reason for this is that the blades are slightly larger
	than the chippers.  The larger blades are to reduce the splintering.
	The blades can be reground to be equal to the size of the chippers
	at the possible cost of increased splintering. Some say the grooves
	are a benefit because they provide relief for gluing joints. 

	Many people claim that the wobble type is easier to set up.

	The August 1991 Fine Woodworking further studies the features of
	the various types of dado blades.

3). How do I cut the perfect dado if both types of dado blades have
shortcomings?

	Your best bet would be to cut it with a router.

4). Should I buy a Sears blurfl?

	Most people agree that the Sears stationary power tools sold today
	aren't the same quality as the Sears tools sold 20 years ago.  
	It can be argued that if you can't afford to buy a Delta, then
	you should be looking at one of the Taiwanese clones rather than
	looking at Sears.

5). Should I buy a Taiwanese clone blurfl?

	It depends on how much money you have. If you can afford the
	Delta blurfl you should probably get it. Buyers should be
	wary that not all Taiwanese clones are quality machines. The
	general consensus is that Grizzly has good quality control.

	It should be noted that some of Delta tools are now being made
	in Taiwan. One would hope that Delta quality control is better than
	some of the cheaper imports.


6). How do I remove paint?

	There are many ways to strip paint from wood.

	Paint can be removed by scraping and/or sanding.
	Paint can be removed by using chemical paint removers.
	Paint can be removed by using heat.
	Paint can be removed by sandblasting.
	Paint can be removed by a new product known as Peel-Away.
	Rumor has it that oven cleaner also works.

	If you know of another way to remove paint please feel free to pass
	the information along. 

7). Should I use a hot melt glue gun for my next project?

	The general consensus is that hot melt glue is not adequate
	for woodworking projects. However, hot melt glue guns can
	have a place in the shop. Many people like to use them for
	tacking items together such as when building forms or jigs.

8) Where can I get plans for the New Yankee Workshop projects?

	Plans for any of Norm's projects can be ordered for $7.50 from

        (project name)
        New Yankee Workshop
        P.O. Box 645
        Bedford, MA  01730

	Videos, which include a copy of the plans, cost $24.95 plus shipping
	and handling, from 800-272-0280.  Both the address and phone number
	are given at the end of each show.

	Most of the projects from the first two seasons are in the two
	New Yankee Workshop books.  For the workbench, one important
	dimension is *not* given in the book, though it can, I think,
	be calculated.

9) What is the best woodworking magazine?

	There are many good woodworking magazines. Two that are frequently
	recommended in this group are Fine Woodworking and Woodsmith.

	Fine Woodworking is a bit on the artsy side and more for the
	experienced woodworker. It does not get into the small details
	of a project.

	Woodsmith provides much more details for projects. Woodsmith is
	well suited for both the amateur and experienced woodworker.

10) What is a board foot?

	A board foot is a common unit used in the measurement of wood.
	It is equal to 1 foot length x 1 foot width x 1 inch thick.
	It should be noted that the thickness is nominal thickness.
	After drying and surfacing the usual thickness of a 1 inch
	board is 13/16.

	A board 10 feet long x 1 foot wide x 2 inches thick would be
	equal to 20 board feet.

11) What is the correct way to handle the glue squeeze out problem?

	Use the right amount of glue.  The (obvious) danger is a glue
	starved joint.

	 Wipe off the excess glue immediately with a damp sponge or paper
	towel.  This method gets mixed reviews.  Some claim the water-glue
	mixture will soak into the wood and show up when the piece is finished.
	Others say that this is not a problem.  The effectiveness of this
	method probably depends on the type of wood and finish that are used.

	Allow the glue to harden somewhat (1/2 - 2 hrs) and then
	chisel/scrape it off.  Some recommend removing the glue after it
	begins to film over.

	Either finish the pieces ahead of time or apply paste wax.  This
	should prevent the glue from sticking.  The problem with this is
	removing the paste wax prior to finishing.

	Use a plastic drinking straw cut at 45 degrees to scoop the glue
	out of the inside corner.  As the straw fills up, it can be trimmed to
	provide a fresh surface.

12) What books should I purchase to learn about various aspects of woodworking?

	Thanks to Ken Smith (kensmith@cs.Buffalo.EDU) for providing the
	ISBN numbers along with a couple of additions to the list.

13) How do I finish toys so that they are non-toxic?

	a.  Behlens Salad Bowl Finish.  This product has been approved by
	    the FDA for use on objects that will come in contact with
	    food.  It produces a nice, semi-gloss finish.
	b.  Any vegetable oil. Could become rancid after a period of time.
	c.  Walnut oil.  It reacts with the air and hardens into a true
	    finish.  It works particularly well when the oil is heated
	    and the item is dipped into the warm oil. Available at health
	    food or large grocery stores.  Don't buy the gourmet stuff!
	d.  Mineral oil or vaseline.
	e.  Water-based polyurethanes.  These are new products which are
	    very different from the more familiar oil-based
	    polyurethanes.  They are totally non-toxic, dry quickly, and
	    have no strong odors when applying.
	f.  Pure Tung Oil. It has no driers or solvents. It is essentially
	    just a vegetable oil but produces a nice finish that won't go
	    rancid. Use only Tung Oil that is "pure".
	g.  Rumor has it that shellac is also safe once it dries. I have
	    been unable to verify this.
	h.  Leave items unfinished.

15) How do I finish the edge of plywood?
	a) Wood tape. It comes in 2 forms, one that can be ironed on, and
	   one that can be contact cemented on. The tape is approximately
	   1 inch wide, and can be trimmed with a plane, router, or knife.
	b) Glue strips of wood, either purchased or cut from lumber.

16). Which saw blade should I buy?
	There is an excellent article on evaluating carbide tipped
	sawblades in issue #72 of Fine Homebuilding (March 1992).

	To summarize the article:

	An expensive blade will typically last longer than a cheap
	blade and the cost difference is made up by the number of
	extra sharpenings available from the investment.

	A blade that has been tensioned will run truer and cost more
	than a blade that hasn't been tensioned.

	Carbide blades will last up to 60 times longer than steel blades.

17). Where are the archives for rec.woodworking?
	There are 2 archives that I know about.

	The first is ftp.cs.purdue.edu in /pub/sjc/woodworking. Currently
	it contains a list of Woodsmith plans.

	The second is ftp.cs.rochester.edu in /pub/rec.woodworking. Currently
	it contains summaries of past discussions of tools, some
	safety related notes, and some of the FAQ postings. Below is
	the current list of files available for ftp from cs.rochester.edu:

18). Where can I find cradle plans?

	1.  Garrett Wade
		$9.95 for plans for a "rocking cradle
		item number 14A03.SA in their 1993 tools catalog

	2.  The Woodworkers' Store
		$4.95 for plans for a "four post cradle"
		item number 40360 in their 1991-2 catalog

	3.  The August 1990 issue of Fine Woodworking has an article about
		making a cradle.

	4. Bartley offers a cradle kit for $199.  If it's up to the quality
		of their other kits, this should be good.

	5. Woodsmith issue #48 - cradle with frame and panel ends with
		arched-top panels.


19). Where can I find futon plans?

	1. TODAYS WOODWORKER JULY/AUG 1989, VOL 1 NO. 4
		Queen size futon folded in half length wise.
		Very attractive Futon sofa bed frame for queen size
		futon (possibly Swedish modern). Unfolds to make bed,
		breaks down for moving.  Elegant design with lots of
		mortise and tenon joinery.

	2. WOODWORKER'S JOURNAL NOV/DEC 1992 VOL 16 NO. 6
		"Standard" futon frame for standard 2 fold futon.
		Classic bi fold futon frame for queen size futon. The
		plans claim to be (and appear to be) appropriate for
		"even beginning woodworkers".

	3. Fine Woodworking    July/August '89 NO. 77

	4. Specialty Furniture Designs (800-892-4026)
		Design "WSN-15" $14.95
		Catalog $2.00
		Attractive (modern) Sofa like futon frame fro singe fold
		futon (futon folds once (the long way)).  Plans for both
		twin (39 x 75) and full (54 x 75).
		Plans are a large single sheet of blue print like drawings
		with associated text, construction looks reasonable and
		pictures of the finished project look good, but the plans
		are a bit intimidating

	5. Popular Woodworking SEP 1992, issue #68
		"Knock-Down Couch"
		Attractive Mission / Craftsman like design for a sturdy,
		knock-down couch. The plans are not specifically for
		futons but could be easily adapted to a single fold futon
		(might not need to be adapted).


20). Where can I get information about particle board?

	The following was provided by Stavros Macrakis (macrakis@osf.org)
	and was added to the FAQ with his permission.

	*********************************************************************
	For technical information on particleboard (PB), the National
	Particleboard Association puts out some very nice free pamphlets,
	which I summarize below.  Although they are basically addressed to
	industrial users, they cover particleboard joint techniques quite well
	for the rest of us.  Some of the facts about joints are very surprising.

	I've tried to summarize the essential information below, but you can
	also order copies from: NPA, 18928 Premiere Court, Gaithersburg,
	MD 20879.

	Specifier's Guide to PB and MDF

  	Abstract
		There are 15 ANSI grades of particleboard, with diverse
  	properties.  For instance, face screwing strength varies from 90-450
  	lb, stiffness from 80,000-500,000 psi.  Recommendations are given
  	for matching grade to use.

	Dowel Holding Strength of PB and MDF

  	Abstract
		Dowels joints are one of the cost common adhesive-based
  	furniture assembly joints.  Dowelling is a simple, inexpensive, and
  	reliable means of making butt and miter joints.  Joint strength is
  	largely determined by the holding power of the dowels.  Use good
  	quality dowels, diameter <= 0.5x the stock thickness.  The longer
  	the dowel, the greater the strength.  Holes should be 0.005"
  	oversized for edges, same as dowel on faces.  Use 60%+ solids
  	content PVA adhesive, applying glue to both dowel and hole wall,
  	with slight squeeze-out.

	Adhesive-based Corner Joints for PB and MDF

  	Abstract
		The thicker the panel, the stronger the joint.  Simple butt
  	joints' strength is limited by delamination; glue blocks or edge
  	banding help.  Dowel joints are standard, and work well; they should be
  	glued only at the dowels, NOT between edge and face (!).  Four dowels
  	for 18" are standard.  Biscuits have equivalent strength, but are
  	easier to align at assembly.  The strength of a well-made simple miter
  	joint without reinforcement (dowels, etc.) is generally comparable to
  	that of dowelled butt joints (!); dowels add little strength, but
  	splines and biscuits do.  Rabbets 1/3-1/2 the depth of the panel make
  	strong joints, but tend to split.  Dados are better, but less
  	attractive.  Rabbet and dado butt corner joints (= dado and tenon =
  	dado box corner) combine a dado on one panel and a rabbet on the other.
  	Dowelled butt joints are stronger (!).  Dovetails are excellent, but
  	require precise and time-consuming machining.  Molded polyurethane
  	joints (plastic splines) are as strong as or stronger than dowel
  	joints.

	Metal Fasteners for PB and MDF

  	Abstract
		Screws, nails, and staples are widely used.  Screws are
  	strongest.  The type of screw affects strength by only +-10% (!), but
  	PB screws are less likely to break.  Screw diameter affects strength
  	little, but screw length directly affects it.  Screw diameter should
  	not exceed 20% of stock thickness.  High internal bond strength PB
  	holds screws better.  Edge screws have half the strength of face
  	screws.  Use full-length pilot holes; shorter holes do not increase
  	strength.  Ideal tightening is 3/4 turn past flush on the face; 3/8
  	past flush on the edge.  Applying glue in the hole can increase
  	strength as much as 45%.
		Staples are used for attaching fabric, etc., and to hold glued
  	joints.
		Nails split panels, so should be >3" from a corner, and >6"
  	apart.  Ring shank nails hold better, plastic coated best.  Drive
  	them at an angle.

	Mechanically-based Corner joints for PB and MDF

  	Abstract
		Most bolt and cam joints are 20-50% weaker than dowelled joints.
  	Screw joints are comparable.  Plastic corner block units can be much
  	stronger in outward bending, but only comparably strong in inward.
  	Even when they are equally strong, mechanically-based joints are often
  	less rigid.  These systems are most useful for ready-to-assemble
  	manufactured kit furniture.

	Particle Shelf Systems (Builder's Bulletin #1)

		(not seen)


	All the above are free.  They also sell:

	Particleboard from Start to Finish $12.50

  	Abstract (theirs, I haven't seen this)
		Ten chapters (120pp) of useful information for users of PB.
  	Includes information on material handling and storage, sanding,
  	machining and tooling, laminating, wet finishing, edge treatments,
  	assembly and fastening, construction products, shelving and
  	formaldehyde.

	MDF from Start to Finish $7.50

  	Similar abstract, 42 pp.

	"Fine woodworking tools. Several stores.  They have a main catalogue, a

Archive-name: woodworking/motors
Last-modified: 3/30/93

This article answers many of the frequently asked questions about electric
motors. 


Motors:

    There are many kinds of motors, but this article considers only two
    kinds used frequently in woodworking tool applications: universal AC/DC
    motors and single-phase induction motors. Universal motors have brushes
    and commutators and are used for portable tools like routers, skilsaws,
    and electric drills.  Single-phase induction motors have no brushes,
    run only on AC electrical power, and are usually found on stationary
    tools such as table saws, drill presses, planers, and jointers.
    There are exceptions to this: some stationary tools use universal
    motors.

    Horsepower:  Motor horsepower is the most misunderstood (and misused)
    electric motor rating.  Neither motor, universal or induction, produces
    usable horsepower unless it is slowed down (by applied mechanical load)
    from no-load speed.  For induction motors, this slowdown is called
    "slip", and the horsepower "developed" by a motor increases with slip
    (to a simple approximation).  This is why induction motors are
    typically rated at 3450 rpm (two pole motor) or 1750 rpm (four pole
    motor).  The rating speed allows for slip from the "synchronous"
    speeds of 3600 and 1800 rpm, respectively.  Universal motors do not
    have a synchronous speed, but have a maximum no-load speed that depends
    upon the voltage applied to the motor.

    Most motors can put out a lot more maximum horsepower than they can
    sustain continuously.  By forcing more mechanical load on the motor,
    slowdown is increased and so therefore is the output horsepower.
    Mechanically, horsepower is torque times rpm, and increasing the
    mechanical load means that the rpm is slowed slightly and the drag
    torque is increased to obtain more torque times rpm.  Electrically,
    horsepower is volts times amps, and by conservation of energy, the
    mechanical output horsepower must be balanced by electrical input
    horsepower.  Since the voltage is relatively constant, this means that
    as a motor is loaded, the input current increases.  But the electrical
    winding impedance has a resistive component, so that higher current
    means more power dissipated in the windings.  In fact, the motor
    windings heat up proportional to the square of the motor current.
    Except for specially designed motors, the current that a motor can
    sustain continuously without burning out its windings is a fraction
    of the current at maximum load.

    Unscrupulous vendors sometimes publish maximum "developed" horsepower
    to make their products seem more capable than they really are.
    Developed horsepower may be two to five times the continuous duty
    rating of a motor.  Such products should be examined to discover the
    continuous duty rating to compare with other, more conservatively
    rated products.

    When the talk is of developed horsepower, the meaning is "peak" which
    for an induction motor is typically the local peak of the torque curve
    near synchronous speed.  A typical induction motor torque curve is:

                                                                     |
          0                   RPM                              1800 or 3600


    As you can see, the curve is very steep in the operating region and in
    fact, the observed operation is typically that once you load the motor
    past the local maximum torque, the speed jumps to the corresponding
    point on the initial portion of the curve or simply stops.  The actual
    operation depends upon the shape of the curve near 0 RPM.

    The Rated HP is typically the torque level at which the motor can be run
    continuously without exceeding the temperature at which the winding
    insulation beaks down.  Since there is thermal mass involved, you can
    operate the motor at higher than rated torque for less than 100% of
    the time and not exceed this temperature if the motor is cool preceding
    the run etc. etc.  etc.

    Typically, two motors with different rated HP develop different HP in a
    ration close to the same as the difference in rating.


    The story is somewhat different for a universal motor such as is used on
    most hand held tools.  In these motors, for a given input voltage, the
    torque goes up as the speed goes down.  The more you load them, the slower
    they run until they stall, at which point their torque is a maximum.
    In this case, the developed horsepower is a the point along the torque
    curve where the speed X torque is a maximum.  As with the induction motor,
    the rated horsepower means you can run the motor there at 100% duty cycle.
    Again, you can load the motor more and it will produce more torque but you
    may only do this on a limited basis.

    The final word is heat.  If you exceed the winding insulation temperature
    rating, you will fail the insulation and ruin the motor ( or pop the
    thermal cutout if so equipped). 



    Application areas:  Universal motors are compact, have high starting
    torque, can run at high rpm, and deal well with rapidly varying
    loads.  They are often used with triac or thyristor speed controls.
    This makes them ideal for portable power tools.  Single-phase
    induction motors are efficient, have a limited rpm selection,
    are relatively heavy and bulky, and are almost maintenance-free.
    They work well in stationary tools that run at one rpm or that have
    a variable-speed transmission.

    Voltage: Both kinds of motors are supplied in popular mains voltages
    (115 or 230) but only induction motors are supplied with winding
    taps that allow either voltage to be selected.  As far as the motor
    is concerned, there is no difference in efficiency when selecting
    either 115 or 230 volts.  This is because such motors have two
    identical sets of windings that are connected in parallel for the lower
    voltage and in series for the higher.  Neither connection results
    in the individual windings seeing a different voltage.  However,
    inadequate wiring can make a difference to motor operation, because
    higher current at 115 volts may give unacceptable wiring voltage drops
    in some shops or garages.  Some wiring voltage drop is expected and
    built into the motor rating.  Nominal pole transformer output (to
    your house) is about 120/240 volts.  Motors are rated for 115/230
    volt operation, which allows for 5/10 volts wiring voltage drop.
    More voltage drop than this can cause low starting torque and
    overheating at rated load.

    115 or 230 volt operation makes no difference to your power company
    either.  The watt-hour meter at your electrical entry measures watts
    regardless of the voltage used.  Your power company does not give
    you a single watt for free, and your PUC (Public Utility Commission)
    won't let the power company charge more than the legal rates.
    Watt-hour meter accuracy is a matter of law in most States.

    Current:  Motors have a nominal current rating which is supposed to be
    the current at rated horsepower and rated voltage.  A motor will not
    draw exactly rated current except in the unlikely circumstance that
    the voltage applied is exactly the rated voltage and the load applied
    is exactly the rated horsepower.  As a matter of fact, most woodworking
    tools spend much of their life spinning without applied load and drawing
    only a small fraction of nameplate rated current.  When the tool begins
    to cut, motor current varies widely depending upon cutting load.  In
    some tools which have relatively small motors, motor current may approach
    several times rated current as the tool is momentarily loaded close
    to stall or breakdown torque.  An exception to this wide variation
    would be something like the motor driving the fan on a dust
    collection system; such motors operate at about rated horsepower all
    the time because the fan presents a constant load.

    For both universal and single-phase induction motors, the full-load
    current is given by

        I  =  (746 * hp) / (eff * pf * voltage)

    where eff is efficiency, pf is power factor, and the others are
    obvious.  In AC systems, the voltage and current waveforms are
    (nominally) sine waves and may differ in phase from each other
    by an angle called the phase angle.  There are 360 phase angle
    degrees in one sinusoidal cycle.  Power factor is the cosine of
    the phase angle, and for motors this angle is normally between
    zero and 90 degrees, current lagging voltage.  In DC systems,
    there is no phase angle, and power factor is defined as 1.0.

    Typical values for single-phase induction motors running at 115
    volts AC are pf = 0.8 and eff = 0.9.  This gives a rule-of-thumb
    value for amps/horsepower at 115 volts of

          9 amps / horsepower

    This figure is probably OK for rule-of-thumb comparison of induction
    and universal motors or reasonability checks as long as you
    remember that it is based on typical values.

    If you are contemplating operating a 115 volt universal motor
    on DC, performance should be slightly better at 115 volts DC
    than it was on AC.  The proper voltage to use is 115 volts DC.
    This is because AC voltages are given as RMS values, which
    are their power-equivalent DC values.  The tool will actually
    endure less voltage stress under DC operation because the
    peak voltage experienced under DC is 0.707 times the AC peak
    voltage.  Switches and contacts, however, may not last as long.

    Starting current can be as much as ten times rated motor current.
    This is usually not a problem for the circuit breaker feeding the
    motor, because modern circuit breakers are typically rated to trip
    instantaneously at about ten times breaker nameplate rating.  For
    currents less than the instantaneous value, the breaker trips due
    to internal heater elements which mimic the heatup characteristics
    of the wiring the breaker is supposed to protect.  Since starting
    currents last only a second or two (unless the motor is jammed),
    motors usually will not trip circuit breakers on starting current if
    the breaker is rated at higher current than the motor nameplate
    current.  This may not be true if you start the motor on a circuit
    which is already loaded close to rating.

    A motor may trip your circuit breaker on time-overcurrent (the
    heaters) even if the motor nameplate current rating appears to be
    within the breaker rating.  This can happen if you continuously
    overload the motor; motor current will then be several times the
    nameplate rating.  There may be other signs of this.  The motor may
    become extremely hot (spit sizzles on the casing).  This is General
    Electric's way of telling you to slow down.

    Breakdown torque:  Single-phase induction motors, unless they are
    designed for torquemotor operation, have a "breakdown" torque rating.
    This refers to the motor torque-versus-rpm curve, which has a peak
    torque somewhere between zero rpm and rated rpm.  If the motor is
    running and load is applied, the motor slows and torque increases
    until breakdown torque is reached.  At this point, further rpm
    reduction causes a reduction of motor-supplied torque, and the motor
    rpm reduces rapidly to zero (it "breaks down").  This is why a saw,
    for instance, appears to suddenly stall as it is overloaded.

    Ventilation: Most motors have one of two kinds of ventilation: fan-
    cooled open housing, or totally enclosed, fan-cooled (TEFC) housing.
    In the former type, a fan attached to the motor shaft draws air
    through the internal parts of the motor and blows it out of
    ventilation slots cut into the motor housing.  Most universal motors
    are of this type because of the need to cool the brushes and to
    exhaust brush carbon dust and commutator copper fragments.  In the
    TEFC type, the motor housing is completely enclosed and no air
    gets to the internal parts of the motor.  Instead, internal heat
    is conducted through the metal housing to fins, where air blown
    by an external fan removes the heat.  Some induction motors have
    this kind of (more expensive) ventilation and they are often used
    in applications where excessive dust or flammable conditions exist.

    Drive gear:  Surprisingly enough, even though many people will look
    at motor horsepower rating, they often completely ignore the drive
    gear attaching the motor to its load.  The drive gear is often a clue
    to the real power rating of the motor-drive combination.  It's
    difficult to determine the rating of enclosed gears, but v-belts
    can give an immediate visual clue.  While larger pulleys increase
    a v-belt rating, a nominal rule of thumb is about one horsepower
    per 1/2 inch v-belt.  Two 5/8 v-belts on large pulleys may be good
    for 4 or 5 horsepower.  One small belt on a motor which "develops"
    3 horsepower is cause for some suspicion.  Actual belt drive ratings
    can be found in manufacturers handbooks (see Gates, for example) or
    in Machinery's Handbook.

    Motor Starters:  Motor starters are big relays mounted in expensive
    metal boxes with heater overloads matched to the motor they start.
    They serve two purposes: 1) The relay contacts are heavy duty and
    are rated for the motor starting current.  Delicate contacts, such
    as those on a pressure switch, will fail if used directly to
    start a large motor.  Delicate contacts are therefore wired to
    operate the motor starter relay rather than the motor.  2)  Wall-
    mounted circuit breakers are designed to protect building wiring,
    not motors plugged into wall receptacles.  If your electrical box
    circuit breaker trips before your motor burns up, it is incidental,
    not on purpose.  However, motor starters are designed to trip on
    heater overload before the motor they start burns up.

    How much horsepower:  This question is often asked and has no easy
    answer.  This is because the amount of horsepower you need depends
    upon your patience, your preferences, and the way you use the
    machine in question.  Here are some pros and cons.  A larger
    horsepower motor (and associated drive gear) has a thicker shaft
    and is typically more robust than a smaller horsepower motor.  It
    responds to overloads and hard cuts more strongly, and may not stall
    in your application.  It does not use very much more power, since
    electric motors use only power demanded plus some motor losses (which
    are somewhat larger for higher rated motors).  On the down side, the
    initial expense of the motor and drive gear is greater.  Higher
    horsepower often requires 230 volt wiring.  The motor and associated
    drive gear and mountings are heavier.  A smaller horsepower motor
    is cheaper, lighter, and may run on 115 volts.  For a careful worker,
    the torque supplied may be sufficient.  On the down side, the tool
    may stall more often and wet wood may be impossible to cut.  The
    drive gear may be less robust and may require more maintenance.  If
    the tool is operated in overload, the 115 volt circuit breaker may
    trip.

Subject: Introduction/Disclaimers

	Although we've done a fair bit of wiring, we are not
	electricians, and we cannot be responsible for what you do.  If
	you're at all uncertain about what is correct or safe, *don't
	do it*.  Contact someone qualified -- a licensed electrician,
	or your local electrical inspector.  Electricity is no joke;
	mistakes can result in shocks, fires, or electrocution.

	Furthermore, our discussion is based on the U.S. National
	Electrical Code (NEC) and the Canadian Electrical code (CEC).
	To the best of our abilities, we have confirmed every detail
	with the electrical code, but we don't quote sections
	simply to keep this thing readable.  If you think we're wrong,
	we invite you to correct us, but please - quote references!

	The NEC and the CEC do not, in and of themselves, have the
	force of law.  Many municipalities adopt it en toto.  Others,
	however, do not.  Check your with your local building
	department (and <provincial> Hydro Inspection Offices in
	Canada) to find out what applies in your area.  Also,
	your local electrical utility may also have special requirements
	for electrical service installation.  Bear in mind, too, that
	we say here applies primarily to ordinary single-family
	residences.  Multi-family dwellings, mobile homes, commercial
	establishments, etc., are sometimes governed by different
	rules.

	Also note that, contrary to popular belief in the U.S. (and in
	some parts of Canada), Canada is not a wholly-owned subsidiary
	of the U.S.  Consequently, the NEC does not apply in Canada.
	Lots of things are the same, including voltages, line
	frequencies, and the laws of physics.  But there are a number
	of crucial differences in the regulations.  Where we can, we've
	noted them, flagging the relevant passages with ``NEC'' or
	``CEC''.

	Remember that the CEC and NEC are minimal standards.  It is often
	smart to go beyond their minimal requirements.

Subject: What is the NEC?  Where can I get a copy?

	The NEC is a model electrical code devised and published by the
	National Fire Protection Association, an insurance industry group.
	It's revised every three years.  The 1993 version has been released.
	You can buy a copy at a decent bookstore, or by calling them directly
	at 800-344-3555.  The code exists in several versions.  There's the
	full text, which is fairly incomprehensible.  There's an abridged
	edition, which has only the sections likely to apply to most houses.
	And there's the NEC Handbook, which contains the ``authorized
	commentary'' on the code, as well as the full text.  That's the
	recommended version.  Unfortunately, there's no handbook for
	the abridged edition.  And the full handbook is expensive --
	US$65 plus shipping and handling.

Subject: What is the CEC?  Where can I get a copy?

	The Canadian Standards Association is an organization made up
	of various government agencies, power utilities, insurance
	companies, electrical manufacturers and other organizations.
	The CSA publishes CSA Standard C22.1 which is updated every two
	or three years.  Each province adopts, with some amendments,
	this standard and publishes a province-specific code book.
	Since each province publishes its own slightly modified
	standard, it would be somewhat confusing to obtain the CSA
	standard itself.  In this FAQ, "CEC" really means the
	appropriate provincial standard.  In particular, this FAQ is
	derived from the Ontario Hydro Electrical Safety Code, 20th
	edition (1990).  Which is in turn based on CSA C22.1-1990 (16th
	edition).  While differences exist between the provinces, an
	attempt has been made to avoid specific-to-Ontario detail.

	The appropriate provincial code can be obtained from electrical
	inspection offices of your provincial power authority.  In
	Ontario, it's Ontario Hydro.  The Ontario Hydro book isn't
	overly fat.  It's about C$25, and includes mailed updates.  I
	hear that these standards are somewhat easier to read than the
	equivalent NEC publications.

	Don't bother asking in Quebec - DIY wiring is banned throughout
	the province.

Subject: Can I do my own wiring?  Extra pointers?

	In most places, homeowners are allowed to do their own wiring.
	In some, they're not.  Check with your local electrical
	inspector.  Most places won't permit you to do wiring on other's
	homes for money without a license.  Nor are you permitted to do
	wiring in "commercial" buildings.  Multiple dwellings (eg: duplexes)
	are usually considered "semi-commercial" or "commercial".  However,
	many jurisdictions will permit you to work on semi-commercial
	wiring if you're supervised by a licensed electrician - if you can
	find one willing to supervise.

	If you do your own wiring, an important point:

	Do it NEAT and WELL!  What you really want to aim for is a better
	job than an electrician will do.  After all, it's your own home,
	and it's you or your family that might get killed if you make
	a mistake.  An electrician has time pressures, has the skills
	and knows the tricks of the trade to do a fast, safe job.
	In this FAQ we've consciously given a few recommendations that
	are in excess of code, because we feel that it's reasonable,
	and will impress the inspector.

	The inspector will know that you're an amateur.  You have to
	earn his trust.  The best way of doing this is to spend your
	time doing as neat a job as possible.  Don't cut corners.
	Exceed specifications.  Otherwise, the inspector may get extremely
	picky and fault you on the slightest transgressions.

	Don't try to hide anything from the inspector.

	Use the proper tools.  Ie: don't use a bread knife to strip
	wires, or twist wires with your fingers.  The inspector
	won't like it, and the results won't be that safe.  And it
	takes longer.  And you're more likely to stick a hunk of
	12ga wire through your hand that way.

	Don't handle house wire when it's very cold (eg: below -10C
	or 16F).  Thermoplastic house wire, particularly older types
	become very brittle.

Subject: What do I need in the way of tools?

	First, there's the obvious -- a hammer, a drill, a few
	screwdrivers, both straight and Phillips-head.  If you're 
	lucky enough to live in Canada (or find a source of CSA-approved
	devices) you need Robertson ("square recess") screwdrivers
	(#1 and #2) instead of phillips.

	For drilling a few holes, a 3/4" or 1" spade bit and 1/4" or
	3/8" electric drill will do.  If you're doing a lot, or
	are working with elderly lumber, we recommend a 1/2" drill
	(right-angle drills are wonderful.  Can be rented) and
	3/4" or 1" screw-point auger drill bits.  These bits pull
	you through, so they're much faster and less fatiguing, even
	in 90 year old hardwood timbers.

	Screw-driver bits are useful for drills, expecially if you
	install your electrical boxes using screws (drywall screws
	work well).
	
	For stripping wire, use a real wire stripper, not a knife or
	ordinary wire cutters.  Don't buy the $3 K-mart "combo stripper,
	crimper and bottle opener" types.  You should expect to pay
	$15 to $20 for a good "plier-type" pair.  It will have sized
	stripping holes, and won't nick or grab the wire - it should
	be easy to strip wire with it.  One model has a small hole in the
	blade for forming exact wire loops for screw terminals.  There
	are fancier types (autostrip/cut), but they generally aren't
	necessary, and pros usually don't use them.

	A pair of diagonal side cutter pliers are useful for clipping ends
	in constricted places.  Don't use these for stripping wire.

	You will need linesman pliers for twisting wires for wire nuts.

	You should have a pair of needle-nose pliers for fiddling
	inside boxes and closing loops, but it's better to form wire
	loops with a "loop former hole" on your wire stripper - more
	accurate.

	If you're using non-metallic cable, get a cable stripper for
	removing the sheath.  Or, do what some pros do, they nick the
	end of the sheath, grab the ground wire with a pair of pliers,
	and simply rip the sheath back using the ground wire as a
	"zipper", and cut the sheath off.  You shouldn't try to strip
	the sheath with a knife point, because it's too easy to
	slash the insulation on the conductors.  Apparently Stanley
	utility knives fitted with linoleum cutters (hooked blades)
	can be used to strip sheath, but there is still the possibility
	that you'll gouge the conductors.

	For any substantial amount of work with armored cable, it's well
	worth your while to invest in a rotary cable splitter (~US$ 18).
	Hack saws are tricky to use without cutting into the wire
	or the insulation.

	Three-prong outlet testers are a quick check for properly-wired
	outlets.  About $6.  Multimeters tell you more, but are a lot more
	expensive, and probably not worth it for most people.  A simple
	voltage sensor, which can detect potential through an insulated
	wire not supplying any devices, is extremely helpful; they cost
	about US$ 10 at Radio Shack.

	You should have a voltage detector - to check that the wires are
	dead before doing work on them.  Neon-bulb version are cheap ($2-3)
	and work well.  If you get more serious, a "audible alarm" type is
	good for tracing circuits without a helper.  (Though I've been known
	to lock the drill on, and hit breakers until the scream stops ;-)

	For running wires through existing walls, you need fish tape.
	Often, two tapes are needed, though sometimes, a bent hanger or
	a length of thin chain will suffice.  Fish tapes can be rented.

	Electrical tape.  Lots of it ;-)  Seriously, a good and competent
	wiring job will need very little tape.  The tape is useful for
	wrapping dicy insulation in repair work.  Another use is to wrap 
	around the body of outlets and switches to cover the termination
	screws - I don't do this, but drywall contractors prefer it (to
	prevent explosions when the drywall knife collides with a live outlet
	that has no cover plate).

Subject: What is UL listing?

	The UL stands for "Underwriters Laboratory".  It used to be
	an Insurance Industry organization, but now it is independent
	and non-profit.  It tests electrical components and equipment
	for potential hazards.  When something is UL-listed, that means
	that the UL has tested the device, and it meets their requirements
	for safety - ie: fire or shock hazard.  It doesn't necessarily
	mean that the device actually does what it's supposed to, just
	that it probably won't kill you.

	The UL does not have power of law in the U.S. -- you are
	permitted to buy and install non-UL-listed devices.  However,
	insurance policies sometimes have clauses in them that will
	limit their liability in case of a claim made in response to
	the failure of a non-UL-listed device.  Furthermore, in
	many situations the NEC will require that a wiring component
	used for a specific purpose is UL-listed for that purpose.
	Indirectly, this means that certain parts of your wiring
	must be UL-listed before an inspector will approve it and/or
	occupancy permits issued.
	
Subject: What is CSA approval?

	Every electrical device or component must be certified by the
	Canadian Standards Association before it can be sold in
	Canada.  Implicit in this is that all wiring must be done
	with CSA-approved materials.  They perform testing similar to
	the UL (a bit more stringent), except that CSA approval is
	required by law.

	Again, like the UL, if a fire was caused by non-CSA-approved
	equipment, your insurance company may not have to pay the
	claim.

	Note: strictly speaking, there usually is a legal way around the
	lack of a CSA sticker.  In some cases (eg: Ontario), a local hydro
	inspection prior to purchase, or prior to use, is acceptable.
	The hydro inspector will affix a "hydro sticker" to the unit, which
	is as good as CSA approval.  But it costs money - last I knew,
	$75 per unit inspected.

	ULC (Underwriters Laboratory of Canada) is an independent organization
	that, amongst other things, undertakes the quarterly inspection of
	manufacturer's to ensure continued compliance of UL Listed/Recognized
	products to Agency reports and safety standards. This work is done under
	contract to UL Inc (Follow-up Services Division). They are not
	a branch or subsidiary of UL.




Subject: Are there any cheaper, easier to read books on wiring?

	USA: The following three books were suggested by our readers

	    Residential Wiring
	    by Jeff Markell,
	    Craftsman Books,
	    Carlsbad CA for $18.25. ISBN 0-934041-19-9.

	    Practical Electrical Wiring
	    Residential, Farm and Industrial,  Based on the National
	    Electrical Code    ANSI/NFPA 70
	    Herbert P. Richter and W. Creighton Schwan
	    McGraw-Hill Book Co.

	    Wiring Simplified
	    H. P. Richter and W. C. Schwan
	    Park Publishing Co.
	
	Try to make sure that the book is based on the latest NEC
	revision.  Which is currently 1993.

	Canada: P.S. Knight authors and publishes a book called
	"Electrical Code Simplified".  There appears to be a version
	published specific to each province, and is very tied into the
	appropriate provincial code.  It focuses on residential wiring,
	and is indispensible for Canadian DIY'ers.  It is better to get
	this book than the CEC unless you do a lot of wiring (or answer
	questions on the net ;-).

	It is updated each time the provincial codes are.  This book is
	available at all DIY and hardware stores for less than C$10.

Subject: Inspections how and what?  Why should I get my wiring inspected?

	Most jurisdictions require that you obtain a permit and
	inspections of any wiring that is done.  Amongst other more
	mundane bureaucratic reasons (like insurance companies not
	liking to have to pay claims), a permit and inspections
	provides some assurance that you, your family, your neighbors
	or subsequent owners of your home don't get killed or lose
	their homes one night due to a sloppy wiring job.

	Most jurisdictions have the power to order you to vacate your
	home, or order you to tear out any wiring done without a
	permit.  California, for instance, is particularly nasty about
	this.

	If fire starts in your home, and un-inspected wiring is at
	fault, insurance companies will often refuse to pay the damage
	claims.

	In general, the process goes like this:
		- you apply to your local inspections office or building
		  department for a permit.  You should have a sketch or
		  detailed drawing of what you plan on doing.  This is
		  a good time to ask questions on any things you're not
		  sure of.  If you're doing major work, they may impose
		  special conditions on you, require loading
		  calculations and ask other questions.  At this point
		  they will tell you which inspections you will need.
		- If you're installing a main panel, you will need to
		  have the panel and service connections inspected
		  before your power utility will provide a connection.
		  This is sometimes done by the local power authority
		  rather than the usual inspectors.
		- After installing the boxes and wiring, but before
		  the insulation/walls go up, you will need a
		  "rough-in" inspection.
		- After the walls are up, and the wiring is complete,
		  you will need a "final inspection".

Subject: My house doesn't meet some of these rules and regulations.
	Do I have to upgrade?

	In general, there is no requirement to upgrade older dwellings,
	though there are some exceptions (ie: smoke detectors in some
	cases).  However, any new work must be done according to the
	latest electrical code.  Also, if you do ``major'' work, you
	may be required to upgrade certain existing portions or all
	of your system.  Check with your local electrical inspector.

Subject: A word on voltages: 110/115/117/120/125/220/240

	One thing where things might get a bit confusing is the
	different numbers people bandy about for the voltage of
	a circuit.  One person might talk about 110V, another 117V
	or another 120V.  These are all, in fact, exactly the same
	thing...  In North America the utility companies are required
	to supply a split-phase 240 volt (+-5%) feed to your house.
	This works out as two 120V +- 5% legs.  Additionally, since there
	are resistive voltage drops in the house wiring, it's not
	unreasonable to find 120V has dropped to 110V or 240V has dropped
	to 220V by the time the power reaches a wall outlet.  Especially
	at the end of an extension cord or long circuit run.  For a number
	of reasons, some historical, some simple personal orneryness,
	different people choose call them by slightly different numbers.
	This FAQ has chosen to be consistent with calling them "110V" and
	"220V", except when actually saying what the measured voltage will
	be.  Confusing?  A bit.  Just ignore it.

	One thing that might make this a little more understandable
	is that the nameplates on equipment ofen show the lower (ie: 110V
	instead of 120V) value.  What this implies is that the device
	is designed to operate properly when the voltage drops that
	low.

	208V is *not* the same as 240V.  208V is the voltage between
	phases of a 3-phase "Y" circuit that is 120V from neutral to any
	hot.   480V is the voltage between phases of a 3-phase "Y"
	circuit that's 277V from hot to neutral.

	In keeping with 110V versus 120V strangeness, motors intended
	to run on 480V three phase are often labelled as 440V...

Subject: What does an electrical service look like?

	There are logically four wires involved with supplying the
	main panel with power.  Three of them will come from the utility
	pole, and a fourth (bare) wire comes from elsewhere.

 	The bare wire is connected to one or more long metal bars pounded
 	into the ground, or to a wire buried in the foundation, or sometimes
 	to the water supply pipe (has to be metal, continuous to where
	the main water pipe entering the house.  Watch out for galvanic
	action conductivity "breaks" (often between copper and iron pipe).
	This is the "grounding conductor".  It is there to make sure that
	the third prong on your outlets is connected to ground.  This wire
	normally carries no current.

	One of the other wires will be white (or black with white or
	yellow stripes, or sometimes simply black).  It is the neutral wire.
	It is connected to the "centre tap" (CEC; "center tap" in the
	NEC ;-) of the distribution transformer supplying the power.  It
	is connected to the grounding conductor in only one place (often
	inside the panel).  The neutral and ground should not be connected
	anywhere else.  Otherwise, weird and/or dangerous things may happen.

	Furthermore, there should only be one grounding system in
	a home.  Some codes require more than one grounding electrode.
	These will be connected together, or connected to the neutral
	at a common point - still one grounding system.  Adding additional
	grounding electrodes connected to other portions of the house
	wiring is unsafe and contrary to code.

	If you add a subpanel, the ground and neutral are usually
	brought as separate conductors from the main panel, and are
	not connected together in the subpanel (ie: still only one
	neutral-ground connection).  However, in some situations 
	(certain categories of separate buildings) you actually do
	have to provide a second grounding electrode - consult your
	inspector.

	The other two wires will usually be black, and are the "hot"
	wires.  They are attached to the distribution transformer as
	well.

	The two black wires are 180 degrees out of phase with each
	other.  This means if you connect something to both hot wires,
	the voltage will be 220 volts.  If you connect something to the
	white and either of the two blacks you will get 110V.

	Some panels seem to only have three wires coming into them.
	This is either because the neutral and ground are connected
	together at a different point (eg: the meter or pole) and one
	wire is doing dual-duty as both neutral and ground, or in some
	rare occasions, the service has only one hot wire (110V only
	service).

Subject: What is a circuit?

	Inside the panel, connections are made to the incoming wires.
	These connections are then used to supply power to selected
	portions of the home.  There are three different combinations:
		1) one hot, one neutral, and ground: 110V circuit.
		2) two hots, no neutral, and ground: 220V circuit.
		3) two hots, neutral, and ground: 220V circuit + neutral,
		   and/or two 110V circuits with a common neutral.

	(1) is used for most circuits supplying receptacles and
	lighting within your house.  (3) is usually used for supplying
	power to major appliances such as stoves, and dryers - they
	often have need for both 220V and 110V, or for bringing several
	circuits from the panel box to a distribution point.  (2) is
	usually for special 220V motor circuits, electric heaters, or
	air conditioners.

	[Note: In the US, the NEC frequently permits a circuit similar
	to (2) be used for stoves and dryers - namely, that there
	are two hot wires, and a wire that does dual duty as neutral
	and ground, and is connected to the frame as well as providing
	the neutral for 110V purposes - three prong plugs instead
	of four (*only* for stoves/dryers connected to the main panel.
	When connected to most sub-panels, 4 prong plugs and receptacles
	are required).  In our not-so-humble opinion this is crazy, but
	the NFPA claims that this practice was re-evaluated for the 1992 NEC,
	and found to be safe.  Check your local codes, or inquire as to
	local practice -- there are restrictions on when this is
	permissible.]

	(1) is usually wired with three conductor wire: black for hot,
	white for neutral, and bare for grounding.

	(2) and (3) have one hot wire coloured red, the other black, a
	bare wire for grounding, and in (3) a white wire for neutral.

	You will sometimes see (2) wired with just a black, white and ground
	wire.  Since the white is "hot" in this case, both the NEC and CEC
	requires that the white wire be "permanently marked" at the ends
	to indicate that it is a live wire.  Usually done with paint, nail
	polish or sometimes electrical tape.

	Each circuit is attached to the main wires coming into the
	panel through a circuit breaker or fuse.

	There are, in a few locales, circuits that look like (1), (2)
	or (3) except that they have two bare ground wires.  Some places
	require this for hot tubs and the like (one ground is "frame ground",
	the other attaches to the motor).  This may or may not be an
	alternative to GFCI protection.

Subject: "grounding" versus "grounded" versus "neutral".

	According to the terminology in the CEC and NEC, the
	"grounding" conductor is for the safety ground, i.e., the green
	or bare or green with a yellow stripe wire.  The word "neutral"
	is reserved for the white when you have a circuit with more than 
	one "hot" wire.  Since the white wire is connected to neutral and
	the grounding conductor inside the panel, the proper term is
	"grounded conductor".  However, the potential confusion between
	"grounded conductor" and "grounding conductor" can lead to
	potentially lethal mistakes - you should never use the bare wire
	as a "grounded conductor" or white wire as the "grounding conductor",
	even though they are connected together in the panel.

	[But not in subpanels - subpanels are fed neutral and ground
	separately from the main panel.  Usually.]

	Note: do not tape, colour or substitute other colour wires for the
	safety grounding conductor.

	In the trade, and in common usage, the word "neutral" is used
	for "grounded conductor".  This FAQ uses "neutral" simply to
	avoid potential confusion.  We recommend that you use "neutral"
	too.  Thus the white wire is always (except in some light
	switch applications) neutral.  Not ground.

Subject: What does a fuse or breaker do?  What are the differences?

	Fuses and circuit breakers are designed to interrupt the power
	to a circuit when the current flow exceeds safe levels.  For
	example, if your toaster shorts out, a fuse or breaker should
	"trip", protecting the wiring in the walls from melting.  As
	such, fuses and breakers are primarily intended to protect the
	wiring -- UL or CSA approval supposedly indicates that the
	equipment itself won't cause a fire.

	Fuses contain a narrow strip of metal which is designed to melt
	(safely) when the current exceeds the rated value, thereby
	interrupting the power to the circuit.  Fuses trip relatively
	fast.  Which can sometimes be a problem with motors which have
	large startup current surges.  For motor circuits, you can use
	a "time-delay" fuse (one brand is "fusetron") which will avoid
	tripping on momentary overloads.  A fusetron looks like a
	spring-loaded fuse.  A fuse can only trip once, then it must be
	replaced.

	Breakers are fairly complicated mechanical devices.  They
	usually consist of one spring loaded contact which is latched
	into position against another contact.  When the current flow
	through the device exceeds the rated value, a bimetallic strip
	heats up and bends.  By bending it "trips" the latch, and the
	spring pulls the contacts apart.  Circuit breakers behave
	similarly to fusetrons - that is, they tend to take longer to
	trip at moderate overloads than ordinary fuses.  With high
	overloads, they trip quickly.  Breakers can be reset a finite
	number of times - each time they trip, or are thrown
	when the circuit is in use, some arcing takes place, which
	damages the contacts.  Thus, breakers should not be used in
	place of switches unless they are specially listed for the
	purpose.

	Neither fuses nor breakers "limit" the current per se.  A dead
	short on a circuit can cause hundreds or sometimes even
	thousands of amperes to flow for a short period of time, which
	can often cause severe damage.

Subject: Breakers?  Can't I use fuses?

	Statistics show that fuse panels have a significantly higher
	risk of causing a fire than breaker panels.  This is usually
	due to the fuse being loosely screwed in, or the contacts
	corroding and heating up over time, or the wrong size fuse
	being installed, or the proverbial "replace the fuse with a
	penny" trick.

	Since breakers are more permanently installed, and have better
	connection mechanisms, the risk of fire is considerably less.

	Fuses are prone to explode under extremely high overload.  When
	a fuse explodes, the metallic vapor cloud becomes a conducting
	path.  Result?  From complete meltdown of the electrical panel,
	melted service wiring, through fires in the electrical
	distribution transformer and having your house burn down.
	[This author has seen it happen.]  Breakers won't do this.

	Many jurisdictions, particularly in Canada, no longer permit
	fuse panels in new installations.  The NEC does permit new
	fuse panels in some rare circumstances (requiring the special
	inserts to "key" the fuseholder to specific size fuses)

	Some devices, notably certain large air conditioners, require fuse
	protection in addition to the breaker at the panel.  The fuse
	is there to protect the motor windings from overload.  Check the
	labeling on the unit.  This is usually only on large permanently
	installed motors.  The installation instructions will tell you
	if you need one.

Subject: What size wire should I use?

	For a 20 amp circuit, use 12 gauge wire.  For a 15 amp circuit,
	you can use 14 gauge wire (in most locales).  For a long run,
	though, you should use the next larger size wire, to avoid
	voltage drops.  12 gauge is only slightly more expensive than
	14 gauge, though it's stiffer and harder to work with.

	Here's a quick table for normal situations.  Go up a size for
	more than 100 foot runs, when the cable is in conduit, or
	ganged with other wires in a place where they can't dissipate
	heat easily:

		Gauge		Amps
		14		15
		12		20
		10		30
		8		40
		6		65
	
	We don't list bigger sizes because it starts getting very dependent
	on the application and precise wire type.

Subject: Where do these numbers come from?

	There are two considerations, voltage drop and heat buildup.
	The smaller the wire is, the higher the resistance is.  When
	the resistance is higher, the wire heats up more, and there is
	more voltage drop in the wiring.  The former is why you need
	higher-temperature insulation and/or bigger wires for use in
	conduit; the latter is why you should use larger wire for long
	runs.

	Neither effect is very significant over very short distances.
	There are some very specific exceptions, where use of smaller
	wire is allowed.  The obvious one is the line cord on most
	lamps.  Don't try this unless you're certain that your use fits
	one of those exceptions; you can never go wrong by using larger
	wire.

Subject: What does "14-2" mean?

	This is used to describe the size and quantity of conductors
	in a cable.  The first number specifies the gauge.  The second
	the number of current carrying conductors in the wire - but
	remember there's usually an extra ground wire.  "14-2" means
	14 gauge, two insulated current carrying wires, plus bare ground.

	-2 wire usually has a black, white and bare ground wire.  Sometimes
	the white is red instead for 220V circuits without neutral.  In
	the latter case, the sheath is usually red too.

	-3 wire usually has a black, red, white and bare ground wire.
	Usually carrying 220V with neutral.

Subject: What is a "wirenut"/"marrette"/"marr connector"?  How are they
	used?

	A wire nut is a cone shaped threaded plastic thingummy that's used
	to connect wires together.  "Marrette" or "Marr connector"
	are trade names.  You'll usually use a lot of them in DIY wiring.

	In essence, you strip the end of the wires about an inch, twist them
	together, then twist the wirenut on.

	Though some wirenuts advertise that you don't need to twist the
	wire, do it anyways - it's more mechanically and electrically
	secure.

	There are many different sizes of wire nut.  You should check
	that the wire nut you're using is the correct size for the
	quantity and sizes of wire you're connecting together.

	Don't just gimble the wires together with a pair of pliers or
	your fingers.  Use a pair of blunt nose ("linesman") pliers,
	and carefully twist the wires tightly and neatly.  Sometimes
	it's a good idea to trim the resulting end to make sure it
	goes in the wirenut properly.

	Some people wrap the "open" end of the wirenut with electrical
	tape.  This is probably not a good idea - the inspector may
	tear it off during an inspection.  It's usually done because
	a bit of bare wire is exposed outside the wire nut - instead
	of taping it, the connection should be redone.

Subject: What is a GFI/GFCI?

	A GFCI is a ``ground-fault circuit interrupter''.  It measures
	the current current flowing through the hot wire and the
	neutral wire.  If they differ by more than a few milliamps, the
	presumption is that current is leaking to ground via some other
	path.  This may be because of a short circuit to the chassis of
	an appliance, or to the ground lead, or through a person.  Any
	of these situations is hazardous, so the GFCI trips, breaking
	the circuit.

	GFCIs do not protect against all kinds of electric shocks.  If,
	for example, you simultaneously touched the hot and neutral
	leads of a circuit, and no part of you was grounded, a GFCI
	wouldn't help.  All of the current that passed from the hot
	lead into you would return via the neutral lead, keeping the
	GFCI happy.

	The two pairs of connections on a GFCI outlet are not symmetric.
	One is labeled LOAD; the other, LINE.  The incoming power feed
	*must* be connected to the LINE side, or the outlet will not be
	protected.  The LOAD side can be used to protect all devices
	downstream from it.  Thus, a whole string of outlets can be
	covered by a single GFCI outlet.

Subject: Where should GFCIs be used?

	The NEC mandates GFCIs for 110V, 15A or 20A single phase
	outlets, in bathrooms, kitchens within 6' of the sink, wet-bar
	sinks, roof outlets, garages, unfinished basements or crawl spaces,
	outdoors, near a pool, or just about anywhere else where you're likely
	to encounter water or dampness.  There are exceptions for inaccessible
	outlets, those dedicated to appliances ``occupying fixed space'',
	typically refrigerators and freezers, and for sump pumps and
	laundry appliances.

	The NEC now requires that if your replace an outlet in a
	location now requiring GFCI, you must install GFCI protection.
	Note in particular - kitchen and bathroom outlets.

	When using the "fixed appliance" rule for avoiding GFCI outlets,
	single outlet receptacles must be used for single appliances,
	duplex receptacles may be used for two appliances.

	The CEC does not mandate as many GFCIs.  In particular, there
	is no requirement to protect kitchen outlets, or most garage or
	basement outlets.  Basement outlets must be protected if you
	have a dirt floor, garage outlets if they're near the door to
	outside.  Bathrooms and most exterior outlets must have GFCIs,
	as do pools systems and jacuzzi or whirlpool pumps.

	There are many rules about GFCIs with pools and so on.  This
	is outside of our expertise, so we're not covering it in
	detail.  See your inspector.

	When replacing an outlet, it must now be GFCI-protected if
	such would now be required for a new installation.  That is,
	a kitchen outlet installed per the 1984 code need not have
	been protected, but if that outlet is ever replaced, GFCI
	protection must now be added (under NEC).  This is explicit
	in the 1993 NEC, and inspector-imposed in Canada.

	Even if you are not required to have GFCI protection, you may
	want to consider installing it anyway.  Unless you need a GFCI
	breaker (see below), the cost is low.  In the U.S., GFCI
	outlets can cost as little as US$8.  (Costs are a bit higher in
	Canada:  C$12.)  Evaluate your own risk factors.  Does your
	finished basement ever get wet?  Do you have small children?
	Do you use your garage outlets to power outdoor tools?  Does
	water or melted snow ever puddle inside your garage?

Subject: Where shouldn't I use a GFCI?

	GFCIs are generally not used on circuits that (a) don't pose a
	safety risk, and (b) are used to power equipment that must run
	unattended for long periods of time.  Refrigerators, freezers,
	and sump pumps are good examples.  The rationale is that GFCIs
	are sometimes prone to nuisance trips.  Some people claim that
	the inductive delay in motor windings can cause a momentary
	current imbalance, tripping the GFCI.  Note, though, that most
	GFCI trips are real; if you're getting a lot of trips for no
	apparent reason, you'd be well-advised to check your wiring
	before deciding that the GFCI is broken or useless.

Subject: What is the difference between a GFCI outlet and a GFCI breaker?

	For most situations, you can use either a GFCI outlet as the
	first device on the circuit, or you can install a breaker with
	a built-in GFCI.  The former is generally preferred, since GFCI
	breakers are quite expensive.  For example, an ordinary GE
	breaker costs ~US$5; the GFCI model costs ~US$35.  There is one
	major exception:  if you need to protect a ``multi-wire branch
	circuit'' (two or more circuits sharing a common neutral wire),
	such as a Canadian-style kitchen circuit, you'll need a
	multi-pole GFCI breaker.  Unfortunately, these are expensive;
	the cost can range into the hundreds of dollars, depending on
	what brand of panel box you have.  But if you must protect such
	a circuit (say, for a pool heater), you have no choice.

	One more caveat -- GFCI outlets are bulky.  You may want to use
	an oversize box when installing them.  On second thought, use
	large (actually deep) boxes everywhere.  You'll thank yourself
	for it.

	Incidentally, if you're installing a GFCI to ensure that one
	specific outlet is protected (such as a bathroom), you don't
	really have to go to all of the trouble to find the first
	outlet in the circuit, you could simply find the first outlet
	in the bathroom, and not GFCI anything upstream of it.  But
	protecting the whole circuit is preferred.

	When you install a GFCI, it's a good idea to use the little
	"ground fault protected" stickers that come with it and mark
	the outlets downstream of the GFCI.  You can figure out which
	outlets are "downstream", simply by tripping the GFCI with the
	test button and see which outlets are dead.

	Note that the labels are mandatory for GFCI-protected-but-ungrounded
	three prong outlets according to the NEC.

Subject: What's the purpose of the ground prong on an outlet, then?

	Apart from their use in electronics, which we won't comment on,
	and for certain fluorescent lights (they won't turn on without
	a good ground connection), they're intended to guard against
	insulation failures within the device.  Generally, the case of
	the appliance is connected to the ground lead.  If there's an
	insulation failure that shorts the hot lead to the case, the
	ground lead conducts the electricity away safely (and possibly
	trips the circuit breaker in the process).  If the case is not
	grounded and such a short occurs, the case is live -- and if
	you touch it while you're grounded, you'll get zapped.  Of
	course, if the circuit is GFCI-protected, it will be a very
	tiny zap -- which is why you can use GFCIs to replace
	ungrounded outlets (both NEC and CEC).

	There are some appliances that should *never* be grounded.  In
	particular, that applies to toasters and anything else with
	exposed conductors.  Consider:  if you touch the heating
	electrode in a toaster, and you're not grounded, nothing will
	happen.  If you're slightly grounded, you'll get a small shock;
	the resistance will be too high.  But if the case were
	grounded, and you were holding it, you'd be the perfect path to
	ground...

Subject: Why is one prong wider than the other?  Polarization

	Nowadays, many two-prong devices have one prong wider than the
	other.  This is so that the device could rely (not guaranteed!)
	on one specific wire being neutral, and the other hot.
	This is particularly advantageous in light fixtures, where the
	the shell should neutral (safety), or other devices which want to
	have an approximate ground reference (ie: some radios).

	Most 2-prong extension cords have wide prongs too.

	This requires that you wire your outlets and plugs the right
	way around.  You want the wide prong to be neutral, and the
	narrow one hot.  Most outlets have a darker metal for the
	hot screw, and lighter coloured screw for the neutral.
	If not, you can usually figure out which is which by which
	prong the terminating screw connects to.

Subject: How do I convert two prong receptacles to three prong?

	Older homes frequently have two-prong receptacles instead
	of the more modern three.  These receptacles have no safety
	ground, and the cabling usually has no ground wire.  Neither
	the NEC or CEC permits installing new 2 prong receptacles anymore.

	There are several different approaches to solving this:
	    1) If the wiring is done through conduit or BX, and the
	       conduit is continuous back to the panel, you can connect
	       the third prong of a new receptacle to the receptacle
	       box.  NEC mainly - CEC frowns on this practice.
	    2) If there is a copper cold water pipe going nearby, and
	       it's continuous to the main house ground point, you can
	       run a conductor to it from the third prong.
	       NEC: this can only be done if the point of attachment
	       is within 5 feet of where the pipe enters the ground.
	    3) Run a ground conductor back to the main panel.
	    4) Easiest: install a GFCI receptacle.  The ground lug
	       should not be connected to anything, but the GFCI
	       protection itself will serve instead.  The GFCI
	       will also protect downstream (possibly also two prong
	       outlets).  If you do this to protect downstream outlets,
	       the grounds must not be connected together.  Since it
	       wouldn't be connected to a real ground, a wiring fault
	       could energize the cases of 3 prong devices connected
	       to other outlets.  Be sure, though, that there aren't
	       indirect ground plug connections, such as via the sheath
	       on BX cable.

	The CEC permits you to replace a two prong receptacle with a three
	prong if you fill the U ground with a non-conducting goop.
	Like caulking compound.  This is not permitted in the NEC.

	The NEC requires that three prong receptacles without ground
	that are protected by GFCI must be labelled as such.

	See the next section about computers on GFCI-protected groundless
	outlets.

Subject: Surges, spikes, zaps, grounding and your electronics (NEW)

	Theoretically, the power coming into your house is a perfect
	AC sine wave.  It is usually quite close.  But occasionally,
	it won't be.  Lightning strikes and other events will affect
	the power.  These usually fall into two general categories: very
	high voltage spikes (often into 1000s of volts, but usually
	only a few microseconds in length) or surges (longer duration,
	but usually much lower voltage).

	Most of your electrical equipment, motors, transformer-operated
	electronics, lights, etc., won't even notice these one-shot events.
	However, certain types of solid-state electronics, particularly
	computers with switching power supplies and MOS semiconductors,
	can be damaged by these occurances.  For example, a spike can
	"punch a hole" through an insulating layer in a MOS device (such
	as that several hundred dollar 386 CPU), thereby destroying it.

	The traditional approach to protecting your electronics is to use
	"surge suppressors" or "line filters".  These are usually devices
	that you plug in between the outlet and your electronics.

	Roughly speaking, surge suppressors work by detecting overvoltages,
	and shorting them out.  Think of them as voltage limiters.  Line
	filters usually use frequency-dependent circuits (inductors, capacitors
	etc.) to "tune out" undesirable spikes - preventing them from reaching
	your electronics.

	So, you should consider using suppressors or filters on your sensitive
	equipment.

	These devices come in a very wide price range.  From a couple
	of dollars to several hundred.  We believe that you can protect
	your equipment from the vast majority of power problems by selecting
	devices in the $20-50 range.

	A word about grounding: most suppressors and EFI filters require real
	grounds.  Any that don't are next to useless.

	For example, most surge suppressors use MOVs (metal oxide varistors)
	to "clamp" overvoltages.  Yes, you can have a suppressor that only
	has a MOV between neutral and hot to combat differential-mode voltage
	excursions, but that isn't enough.  You need common-mode protection
	too.  Good suppressors should have 3 MOVs, one between each pair of wires.
	Which means you should have a good solid ground.  Eg: a solidly connected
	14ga wire back to the panel.  Not rusty BX armour or galvanized pipe
	with condensation turning the copper connection green.

	Without a ground, a surge or spike is free to "lift" your entire electronics
	system well away from ground.  Which is ideal for blowing out interface
	electronics for printer ports etc.

	Secondly, static electricity is one of the major enemies of electronics.
	Having good frame grounds is one way of protecting against static zaps.

	If you're in the situation of wanting to install computer equipment
	on two wire groundless circuits take note:
	
	Adding a GFCI outlet to the circuit makes the circuit safe for you.
	But it doesn't make it safe for your equipment - you need a ground to
	make surge suppressors or line filters effective.

Subject: Are you sure about GFCIs and ungrounded outlets?
	Should the test button work?

	The NEC, section 210-7(d), and CEC, section 26-700(9), are quite
	explicit that GFCIs are a legal substitute for a grounded outlet
	in an existing installation where there is no ground available in
	the outlet box.

	But your local codes may vary.  As for the TEST button -- there's
	a resistor connecting the LOAD side of the hot wire to the LINE
	side of the neutral wire when you press the TEST button.  Current
	through this resistor shows up as an imbalance, and trips the GFCI.
	This is a simple, passive, and reliable test, and doesn't require
	a real ground to work.  If your GFCI does not trip when you press
	the TEST button, it is very probably defective or miswired.  Again:
	if the test button doesn't work, something's broken, and potentially
	dangerous.  The problem should be corrected immediately.

	The instructions that come with some GFCIs specify that the ground
	wire must be connected.  We do not know why they say this.  The
	causes may be as mundane as an old instruction sheet, or with the
	formalities of UL or CSA listing -- perhaps the device was never
	tested without the ground wire being connected.  On the other hand,
	UL or CSA approval should only have been granted if the device
	behaves properly in *all* listed applications, including ungrounded
	outlet replacement.  (One of us called Leviton; their GFCIs are
	labeled for installation on grounded circuits only.  The technician
	was surprised to see that; he agreed that the NEC does not require
	it, and promised to investigate.)

Subject: What kind of outlets do I need in a kitchen?

	The NEC requires at least two 20 amp ``small appliance
	circuits'' for kitchen counters.  The CEC requires split-duplex
	receptacles.  Outlets must be installed such that no point is more
	than 24" (NEC) (900 mm CEC) from an outlet.  Every counter wider
	than 12" (NEC) or 300 mm (CEC) must have at least one outlet.
	The circuit these outlets are on may not feed any outlets except
	in the kitchen, pantry, or dining room.  Furthermore, these circuits
	are in addition to any required for refrigerators, stoves, microwaves,
	lighting, etc.  Non-dedicated outlets within 6' of a sink *must* be
	protected by a GFCI (NEC only).

	Split duplex receptacles are fed with a 220V circuit.  The tab
	is broken on the hot side of the outlet, and one hot goes to
	the upper outlet, and the other hot goes to the lower outlet.
	The neutral connects to both outlets through one screw.  When
	"carrying through" to another outlet, the neutral must be
	pigtailed, such that removing the outlet, or having the neutral
	connection fall off doesn't cause the neutral to disconnect
	from downstream outlets.

Subject: Where must outlets and switches be in bathrooms?

	There must be at least one outlet in each bathroom, adjacent to
	the sink, in addition to any outlet that may be incorporated in
	the light fixture.  All such outlets *must* be GFCI-protected.

	The NEC says that switches may not be installed inside bathtubs
	or showers.  The CEC says that switches may not be installed
	"within reach" of bathtubs or showers (consult an inspector
	if you can't make it at least four feet).

Subject: General outlet placement rules/line capacities (NEW)

	We paraphrase CEC 26-702 (NEC: 210-52 through 210-63)

	Note: In laying out receptacle outlets, consideration shall be given
	to the placement of electrical baseboards, hot air registers, hot
	water or steam registers, with a view of eliminating cords having to
	pass over hot or conductive surfaces wherever possible.

	NEC:  You're not allowed to put outlets over electric baseboards.
	That, coupled with the spacing requirements, more or less mandates
	the use of baseboards with integral outlets.  Note that such outlets
	are fed by a different branch circuit than the heating elements.

	2. Except as otherwise required, receptacles shall be installed
	in the finished walls of every room or area, other than kitchens,
	bathrooms, hallways, laundry rooms, utility rooms or closests, so
	that no point along the floor line of any usable wall space is more
	than 1.8m (6') horizontally from a receptacle in that or an
	adjoining space, such distance being measured along the floor line
	of the wall spaces involved.

	Fixed dividers, counters, etc., are considered wall space.  Floor
	outlets do not satisfy the requirement unless they are ``near'' the
	wall.  Insofar as practical, outlets should be spaced equidistantly.

	3. At least one duplex receptacle shall be provided in each enclosed
	area such as a balcony or porch that is not classified as a finished
	room or area.

	[NEC doesn't seem to have this rule.]

	4. The receptacles referred to in (2) and (3) shall be duplex
	receptacles or equivalent number of single receptacles.

	5. "Usable wall space" is defined as any wall space 900mm (3', NEC 2')
	or more in width, not to include doorways, areas occupied by a door
	when fully opened, windows which extend to the floor, fireplaces or
	other permanent installations that would limit the use of the wall
	space.

	6.  See kitchen counter requirements.  At least one duplex receptacle
	in eat-in dining area.

	[We don't think the latter part is in the NEC.  Also, the NEC says that
	the two 20-amp small appliance circuits can't go outside of the kitchen,
	dining room, pantry, etc., nor can they be used for anything else,
	except for things like clock outlets, stove accessory outlets, etc.]

	7. Receptacles shall not be mounted facing up in the work surfaces or
	counters of the kitchen or dining area.

	8. No point in a hallway within a dwelling unit shall be more than
	4.5m (15', NEC 10') from a duplex receptacle as measured by the shortest
	path which the supply cord of an appliance connected to the receptacle
	would follow without passing through an openning fitted with a door.
	(vacuum-cleaner rule).

	9. At least one duplex receptacle shall be provided: in laundry
	room, utility room and any unfinshed basement area
	
	[NEC: see GFCI requirements.  There must be a dedicated 20 amp laundry
	receptacle, with no other outlets, plus an additional unfinished
	basement receptacle.  Any attic or crawl space with heating or air
	conditioning equipment must have a receptacle. (this is probably
	in the CEC too.)]

	10, 11, 12, 13:  See bathroom requirements, GFCI, washing machine
	outlet placement.

	14, 15. Outlets shall not be placed in ironing cabinets, cupboards,
	wall cabinets, nor in similar enclosures except where they're
	for specific non-heating appliances (including microwave) in
	the enclosure.

	[NEC: No such requirement.  Are you sure Steven?]

	16, 17. For each single-family dwelling, at least one duplex receptacle
	shall be installed outdoors to be readily available from ground level
	(see GFCI requirements).  Appendix B (additional notes) suggests front
	and back outlets to be controlled by an interior switch.

	[NEC:  One in front, one in back.  No discussion of them being switched.]

	18. At least one duplex receptacle shall be provided for each car space
	in a garage or carport.

	[NEC:  For an attached garage, or detached garage with electric service --
	but there is no requirement that detached garages have power.  This remark
	is probably relevant to CEC as well.]

	19. For the purposes of this rule, all receptacles shall be of the
	grounding type, configuration 5-15R (standard 110V/15A 3 prong).

	20. Any receptacle that is part of a lighting fixture or appliance
	that is > 1.7m (5 feet) above the floor, or in cabinets or cupboards,
	is not counted in the above rules.

	[NEC:  couldn't find an equivalent rule.]

	21. Where a switched duplex outlet is used in lieu of a light outlet
	and fixture, the receptacle shall be considered one of the wall mounted
	receptacles required here.

	22. At least one duplex receptacle shall be provided for a central
	vacuum system if the ducting is installed.

	[NEC:  couldn't find an equivalent rule.]

	Capacities: Knight recommends no more than 10 outlets per circuit.
	Some US references talk about a limit of 12.  There appears to be a
	wattage/area/outlet count calculation somewhere in the NEC.  20A circuits
	may have different rules.
	
	It is open to considerable debate whether you should mix general lighting
	and outlets on individual circuits.  Knight recommends it.  Some netters
	don't.  I tend towards the former for load balancing reasons.

	NEC: There's a new rule on outdoor outlets.  If exposed to the weather,
	and if used for unattended equipment (pool filters, outdoor lighting,
	etc.), the outlet must still be weatherproof even when the device is
	plugged in.

Subject: What is Romex/NM/NMD?  What is BX?  When should I use each?

	Romex is a brand name for a type of plastic insulated wire.
	Sometimes called non-metallic sheath.  The formal name is NM.
	This is suitable for use in dry, protected areas (ie: inside
	stud walls, on the sides of joists etc.), that are not subject
	to mechanical damage or excessive heat.  Most newer homes are
	wired almost exclusively with NM wire.  There are several
	different categories of NM cable.

	BX cable -- technically known as armored cable or "AC" has a
	flexible aluminum or steel sheath over the conductors and is
	fairly resistant to damage.

	TECK cable is AC with an additional external thermoplastic
	sheath.
	
	Protection for cable in concealed locations: where NM or AC cable
	is run through studs, joists or similar wooden members, the outer
	surface of the cable must be kept at least 32mm/1.25" (CEC & NEC)
	from the edges of the wooden members, or the cable should be protected
	from mechanical injury.  This latter protection can take the form of
	metal plates (such as spare outlet box ends) or conduit.

	[Note: inspector-permitted practice in Canada suggests that armored
	cable, or flexible conduit can be used as the mechanical protection,
	but this is technically illegal.]

	Additional protection recommendations: [These are rules in the
	Canadian codes.  The 1993 NEC has many changes that bring
	it close to these rules.  These are reasonable answers to the
	vague "exposed to mechanical damage" in both the NEC and CEC.]

	    - NM cable should be protected against mechanical damage
	      where it passes through floors or on the surface of walls
	      in exposed locations under 5 feet from the floor.
	      Ie: use AC instead, flexible conduit, wooden guards etc.
	    - Where cable is suspended, as in, connections to furnaces
	      or water heaters, the wire should be protected.  Canadian
	      practice is usually to install a junction or outlet
	      box on the wall, and use a short length of AC cable
	      or NM cable in flexible conduit to "jump" to the appliance.
	      Stapling NM to a piece of lumber is also sometimes used.
	    - Where NM cable is run in close proximity to heating
	      ducts or pipe, heat transfer should be minimized by
	      means of a 25mm/1" air space, or suitable insulation
	      material (a wad of fiberglass).
	    - NM cable shall be supported within 300mm/1' of every box
	      or fitting, and at intervals of no more than 1.5m/5'.
	      Holes in joists or studs are considered "supports".
	      Some slack in the cable should be provided adjacent to
	      each box.  [while fishing cable is technically in violation,
	      it is permitted where "proper" support is impractical]
	    - 2 conductor NM cable should never be stapled on edge.
	      [Knight also insists on only one cable per staple, referring
	      to the "workmanship" clause, but this seems more honoured
	      in the breach...]
	    - cable should never be buried in plaster, cement or
	      similar finish, except were required by code [Ie: cable
	      burial with shallow bedrock.].
	    - cable should be protected where it runs behind baseboards.
	    - Cable may not be run on the upper edge of ceiling joists
	      or the lower edges of rafters where the headroom is more
	      than 1m (39").

	Whenever BX cable is terminated at a box with a clamp, small
	plastic bushings must be inserted in the end of the cable to
	prevent the clamps forcing the sharp ends of the armor through
	the insulation.

	Whenever BX cable is buried in thermal insulation, 90C
	wire should be selected, but derated in current carrying
	capacity to 60C.

	BX is sometimes a good idea in a work shop unless covered by
	solid wall coverings.

	In places where damage is more likely (like on the back wall of
	a garage ;-), you may be required to use conduit, a
	UL- (or CSA-) approved metal pipe.  You use various types of
	fittings to join the pipe or provide entrance/exit for the
	wire.

	Service entrances frequently use a plastic conduit.

	In damp places (eg: buried wiring to outdoor lighting) you will
	need special wire (eg: CEC NMW90, NEC UF).  NMW90 looks like
	very heavy-duty NMD90.  You will usually need short lengths of
	conduit where the wire enters/exits the ground.  [See underground
	wiring section.]

 	Thermoplastic sheath wire (such as NM, NMW etc.) should not be
 	exposed to direct sunlight unless explicitly approved for that
 	purpose.

	Many electrical codes do not permit the routing of wire through
	furnace ducts, including cold air return plenums constructed
	by metal sheeting enclosing joist spaces.   The reason for this
	is that if there's a fire, the ducting will spread toxic gasses
	from burning insulation very rapidly through the building.
	Teflon insulated wire is permitted in plenums in many areas.
	
 	Canada appears to use similar wire designations to the US,
 	except that Canadian wire designations usually include the
 	temperature rating in Celsius.  Eg: "AC90" versus "AC".
	In the US, NM-B is 90 degrees celcius.

	NOTE: local codes vary.  This is one of the items that changes
	most often.  Eg: Chicago codes require conduit *everywhere*.
	There are very different requirements for mobile homes.
	Check your local codes, *especially* if you're doing anything
	that's the slightest out of the ordinary.

Subject: Should I use plastic or metal boxes?

	The NEC permits use of plastic boxes with non-metallic cable
	only.  The reasoning is simple -- with armored cable, the box
	itself provides ground conductor continuity.  U.S. plastic
	boxes don't use metal cable clamps.

	The CEC is slightly different.  The CEC never permits cable
	armor as a grounding conductor.  However, you must still
	provide ground continuity for metallic sheath.  The CEC also
	requires grounding of any metal cable clamps on plastic boxes.

	The advantage of plastic boxes is comparatively minor even for
	non-metallic sheathed cable -- you can avoid making one ground
	connection and they sometimes cost a little less.  On the other
	hand, plastic boxes are more vulnerable to impacts.  For
	exposed or shop wiring, metal boxes are probably better.

	Metal receptacle covers must be grounded, even on plastic
	boxes.  This may be achieved by use of a switch with ground
	connection.

Subject: Junction box positioning?

	A junction box is a box used only for connecting wires together.

	Junction boxes must be located in such a way that they're accessible
	later.  Ie: not buried under plaster.  Excessive use of junction
	boxes is often a sign of sloppy installation, and inspectors may
	get nasty.

Subject: Can I install a replacement light fixture?

	In general, one can replace fixtures freely, subject to a few
	caveats.  First, of course, one should check the amperage
	rating of the circuit.  If your heart is set on installing half
	a dozen 500 watt floodlights, you may need to run a new wire
	back to the panel box.  But there are some more subtle
	constraints as well.  For example, older house
	wiring doesn't have high-temperature insulation.  The excess
	heat generated by a ceiling-mounted lamp can and will cause the
	insulation to deteriorate and crack, with obvious bad results.
	Some newer fixtures are specifically marked for high
	temperature wire only.  (You may find, in fact, that your
	ceiling wiring already has this problem, in which case
	replacing any devices is a real adventure.)

	Other concerns include providing a suitable ground for some
	fluorescent fixtures, and making sure that the ceiling box and
	its mounting are strong enough to support the weight of a heavy
	chandelier or ceiling fan.  You may need to install a new box
	specifically listed for this purpose.  A 2x4 across the ceiling
	joists makes a good support.  Metal brackets are also available
	that can be fished into ceilings thru the junction box hole and
	mounted between the joists.

	There are special rules for recessed light fixtures such as
	"pot" lamps or heat lamps.  When these are installed in insulated
	ceilings, they can present a very substantial fire hazard.
	The CEC provides for the installation of pot lamps in insulated
	ceilings, provided that the fixture is boxed in a "coffin" (usually
	8'x16"x12" - made by making a pair of joists 12" high, and covering
	with plywood) that doesn't have any insulation.  (Yes, that's 8 *feet*
	long)

	NEC rules are somewhat less stringent.  They require at least 3"
	clearance between the fixture and any sort of thermal insulation.
	The rules also say that one should not obstruct free air movement,
	which means that a CEC-style ``coffin'' might be worthwhile.
	Presumably, that's up to the local inspector.  [The CEC doesn't
	actually mandate the coffin per-se, this seems to be an inspector
	requirement to make absolutely certain that the fixture can't get
	accidentally buried in insulation.  Ie: if you have insulation blown
	in later.]

	There are now fixtures that contain integral thermal cutouts and
	fairly large cases that can be buried directly in insulation.  They are
	usually limited to 75 watt bulbs, and are unfortunately, somewhat
	more expensive than the older types.  Before you use them, you should
	ensure that they have explicit UL or CSA approval for such uses.
	Follow the installation instructions carefully; the prescribed location
	for the sensor can vary.

	There does not yet appear to be a heat lamp fixture that is approved
	for use in insulation.  The "coffin" appears the only legal approach.

Subject: Noisy fluorescent fixtures, what do I do?

	Many fluorescent fixtures tend to buzz, objectionably so when used in
	residential (rather than warehouse or industrial) situations.  This
	tends to be the result of magnetic/physical resonances at the
	(low) frequencies that standard fixture ballasts operate.  You
	can eliminate this problem by switching to electronic ballasts,
	which operate at a higher (inaudible) frequency.  Unfortunately,
	these are quite expensive.

Subject: What does it mean when the lights brighten when a motor starts?

	This usually means that the neutral wire in the panel is
	loose.  Depending on the load balance, one hot wire may end up
	being more than 110V, and the other less than 110V, with
	respect to ground.  This is a very hazardous situation - it can
	destroy your electronic equipment, possibly start fires, and in
	some situations electrocute you (ie: some US jurisdictions
	require the stove frame connected to neutral).

	If this happens, contact your electrical authority immediately
	and have them come and check out the problem.

	Note: a brief (< 1 second) brightening is sometimes normal with
	lighting and motors on the same 220V with neutral circuit.  A
	loose main panel neutral will usually show increased brightness
	far longer than one second.  In case of doubt, get help.

Subject: What is 3 phase power?  Should I use it?  Can I get it in my house?

	Three phase power has three "hot" wires, 120 degrees out of
	phase with each other.  These are usually used for large motors
	because it is more "efficient", provides a bit more starting torque,
	and because the motors are simpler and hence cheaper.

	You're most likely to encounter a 3 phase circuit that shows
	110 volts between any hot and ground, and 208 volts between
	any two hots.  The latter shows the difference between a normal
	220V/110V common neutral circuit, which is 240 volts between the
	two hots.  There are 3 phase circuits with different voltages.

	Bringing in a 3 phase feed to your house is usually
	ridiculously expensive, or impossible.  If the equipment you
	want to run has a standard motor mount, it is *MUCH* cheaper to
	buy a new 110V or 220V motor for it.  In some cases it is
	possible to run 3 phase equipment on ordinary power if you have
	a "capacitor start" unit, or use a larger motor as a
	(auto-)generator.  These are tricky, but are a good solution if
	the motor is non-standard size, or too expensive or too big to
	replace.  The Taunton Press book ``The Small Shop'' has an
	article on how to do this if you must.

	Note that you lose any possible electrical efficiency by using
	such a converter.  The laws of thermodynamics guarantee that.

Subject: Is it better to run motors at 110 or 220?

	Theoretically, it doesn't make any difference.  However, there
	is a difference is the amount of power lost in the supply
	wiring.  All things being equal, a 110V motor will lose 4 times
	more power in the house wiring than a 220V motor.  This also
	means that the startup surge loss will be less, and the motor
	will get to speed quicker with 220V.  And in some circumstances,
	the smaller power loss will lead to longer motor life.

	This is usually irrelevant unless the supply wires are more
	than 50 feet long.

Subject: What is this nonsense about 3HP on 110V 15A circuits?

	It is a universal physical law that 1 HP is equal to 746
	watts.  Given heating loss, power factor and other inefficiencies,
	it is usually best to consider 1 HP is going to need 1000-1200
	watts.  A 110V 15A circuit can only deliver 1850 watts to a motor,
	so it cannot possibly be more than approximately 2 HP.  Given rational
	efficiency factors, 1.5HP is more like it.

	Some equipment manufacturers (Sears in particular, most router
	manufacturers in general ;-) advertise a HP rating that is far
	in excess of what is possible.  They are giving you a "stall
	horsepower" or similar.  That means the power is measured when
	the motor is just about to stop turning because of the load.
	What they don't mention is that if you kept it in that
|	condition for more than a few seconds your motor will melt - the
|	motor is drawing far more current than its continuous rating.

	When comparing motors, compare the continuous horsepower.  This
	should be on the motor nameplate.  If you can't find that figure,
	check the amperage rating, which is always present.

Subject: How should I wire my shop?

	As with any other kind of wiring, you need enough power for all
	devices that will be on simultaneously.  The code specifies
	that you should stay under 80% of the nominal capacity of the
	circuit.  For typical home shop use, this means one circuit for
	the major power tools, and possibly one for a dust collector or
	shop vac.  Use at least 12 gauge wire -- many power tools have
	big motors, with a big start-up surge.  If you can, use 20 amp
	breakers (NEC), though CEC requires standard 20A receptacles
	which means you'd have to "replug" all your equipment.  Lights
	should either be on a circuit of their own -- and not shared
	with circuits in the rest of the house -- or be on at least two
	separate circuits.  The idea is that you want to avoid a
	situation where a blade is still spinning at several thousand
	RPM, while you're groping in the dark for the OFF switch.

	Do install lots of outlets.  It's easier to install them in the
	beginning, when you don't have to cut into an existing cable.
	It's useful if at least two circuits are accessible at each
	point, so you can run a shop vac or a compressor at the same
	time as the tool you really want.  But use metal boxes and
	plates, and maybe even metal-sheathed cable; you may have
	objects flying around at high speeds if something goes a bit
	wrong.

	Note that some jurisdictions have a "no horizontal wiring"
	rule in workshops or other unfinished areas that are used
	for working.  What this means is that all wiring must be
	run along structural members.  Ie: stapled to studs.

	Other possible shop circuits include heater circuits, 220V
	circuits for some large tools, and air compressor circuits.
	Don't overload circuits, and don't use extension cords if you
	can help it, unless they're rated for high currents.  (A coiled
	extension cord is not as safe as a straight length of wire of
	the same gauge.  Also, the insulation won't withstand as much
	heat, and heat dissipation is the critical issue.)

	If your shop is located at some remove from your main panel,
	you should probably install a subpanel, and derive your shop
	wiring from it.  If you have young children, you may want to
	equip this panel with a cut-off switch, and possibly a lock.
	If you want to install individual switches to ``safe''
	particular circuits, make sure you get ones rated high enough.
	For example, ordinary light switches are not safely able to
	handle the start-up surge generated by a table saw.  Buy
	``horsepower-rated'' switches instead.

	Finally, note that most home shops are in garages or unfinished
	basements; hence the NEC requirements for GFCIs apply.  And
	even if you ``know'' that you'd never use one of your shop
	outlets to run a lawn mower, the next owner of your house might
	have a different idea.

	Note: Fine Woodworking magazine often carries articles on shop
	wiring.  April 1992 is one place to start.

Subject: Doorbell/telephone/cable other service wiring hints.

	Auxiliary services, such as cable, telephone, doorbell, furnace
	control circuits etc. are generally considered to be "class 2"
	wiring by both the CEC and NEC.

	What this generally means is:

		1) class 2 and house power should not share conduit or
		   termination boxes.
		2) class 2 and house power should be 12" apart in walls
		   except where necessary.
		3) cross-over should be at 90 degrees.
	
	While the above may not be strictly necessary to the code, it
	is advantageous anyways - paralleling house power beside telephone
	lines tends to induce hum into the telephone.  Or could interfere
	with fancier furnace control systems.

	With telephone wiring, twisted pair can alleviate these problems,
	and there are new cable types that combine multiple services into
	one sheath.  Consult your inspector if you really want to violate
	the above recommendations.

Subject: Underground Wiring

	You will need to prepare a trench to specifications, use
	special wire, protect the wire with conduit or special plastic
	tubing and possibly lumber (don't use creosoted lumber, it rots
	thermoplastic insulation and acts as a catalyst in the corrosion
	of lead).  The transition from in-house to underground wire is
	generally via conduit.  All outdoor boxes must be specifically
	listed for the purpose, and contain the appropriate gaskets,
	fittings, etc.  If the location of the box is subject to immersion
	in water, a more serious style of water-proof box is needed.  And
	of course, don't forget the GFCIs.

	The required depths and other details vary from jurisdiction to
	jurisdiction, so we suggest you consult your inspector about
	your specific situation.

	A hint: buy a roll of bright yellow tape that says "buried power
	line" and bury it a few inches above where the wire has been placed.

Subject: Aluminum wiring

	During the 1970's, aluminum (instead of copper) wiring became
	quite popular and was extensively used.  Since that time,
	aluminum wiring has been implicated in a number of house fires,
	and most jurisdictions no longer permit it in new installations.
	We recommend, even if you're allowed to, that do not use it for new
	wiring.

	But don't panic if your house has aluminum wiring.  Aluminum
	wiring, when properly installed, can be just as safe as copper.
	Aluminum wiring is, however, very unforgiving of improper
	installation.  We will cover a bit of the theory behind potential
	problems, and what you can do to make your wiring safe.

	The main problem with aluminum wiring is a phenomenon known as
	"cold creep".  When aluminum wiring warms up, it expands.  When
	it cools down, it contracts.  Unlike copper, when aluminum goes
	through a number of warm/cool cycles it loses a bit of tightness each
	time.  To make the problem worse, aluminum oxidises, or corrodes
	when in contact with certain types of metal, so the resistance
	of the connection goes up.  Which causes it to heat up and corrode/
	oxidize still more.  Eventually the wire may start getting very hot,
	melt the insulation or fixture it's attached to, and possibly even
	cause a fire.

	Since people usually encounter aluminum wiring when they move
	into a house built during the 70's, we will cover basic points of
	safe aluminum wiring.  We suggest that, if you're considering purchasing
	a home with aluminum wiring, or have discovered it later, that you
	hire a licensed electrician or inspector to check over the wiring
	for the following things:

	    1) Fixtures (eg: outlets and switches) directly attached to
	       aluminum wiring should be rated for it.  The device will
	       be stamped with "Al/Cu" or "CO/ALR".  The latter supersedes
	       the former, but both are safe.   These fixtures are somewhat
	       more expensive than the ordinary ones.

	    2) Wires should be properly connected (at least 3/4 way around
	       the screw in a clockwise direction).  Connections should be
	       tight.  While repeated tightening of the screws can make the
	       problem worse, during the inspection it would pay off to snug
	       up each connection.

	       Note that aluminum wiring is still often used for the
	       main service entrance cable.  It should be inspected.

	    3) "push-in" terminals are an extreme hazard with aluminum wire.
	       Any connections using push-in terminals should be redone with
	       the proper screw connections immediately.

	    4) There should be no signs of overheating: darkened connections,
	       melted insulation, or "baked" fixtures.  Any such damage should
	       be repaired.
	    
	    5) Connections between aluminum and copper wire need to be
	       handled specially.  Current Canadian codes require that the
	       wire nut used must be specially marked for connecting
	       aluminum to copper.  The NEC requires that the wire be
	       connected together using special crimp devices, with an
	       anti-oxidant grease.  The tools and materials for the latter
	       are quite expensive - not practical to do it yourself unless
	       you can rent the tool.

	    6) Any non-rated receptacle can be connected to aluminum wiring
	       by means of a short copper "pigtail".  See (5) above.
	    
	    7) Shows reasonable workmanship: neat wiring, properly stripped
	       (not nicked) wire etc.
    
	If, when considering purchasing a home, an inspection of the wiring
	shows no problems or only one or two, we believe that you can consider
	the wiring safe.  If there are signs of problems in many places,
	we suggest you look elsewhere.  If the wrong receptacles are used,
	you can replace them with the proper type, or use pigtails - having
	this professionally done can range from $3 to $10 per receptacle/switch.
	You can do this yourself too.

Subject: I'm buying a house!  What should I do?

	Congratulations.  But...  It's generally a good idea to hire
	an inspector to look through the house for hidden gotchas.
	Not just for wiring, but plumbing and structural as well.  If an
	inspection of the wiring shows no problems or only one or two minor
	ones, we believe that you can consider the wiring safe (after any
	minor problems are fixed).  If there are signs of problems in many
	places, we suggest you look elsewhere.

	Here's some hints on what to look for:

	Obvious non-code wiring can include:

		- Zip cord wiring, either concealed or nailed to walls
		- Hot wiring on the identified (neutral) conductor without
		  proper marking.
		- Ungrounded grounding outlets (except when downstream of
		  a GFCI)
		- Splices hanging in mid-air (other than proper knob-and-tube)
		- Switched neutrals
		- Unsecured Romex swinging about like grapevines

	Certain wiring practices that are actually to code (or were at one
	time) sometimes reveal DIY wiring that may have hidden violations:

		- Switches that seem to control nothing (abandoned, perhaps
		   not properly terminated wiring)
		- A wall switch that controls things that you think it
		  shouldn't, for instance mysteriously removing power
		  from lights or outlets in other rooms. 
		- Switches and outlets in bizarre locations
		- Great numbers of junction boxes without outlets or lamps
		- Junction boxes with great numbers of wires going into them
		- Wiring that passes through a closet instead of a wall or
		  ceiling
		- Backwrapped grounding wires (ground wire wrapped around
		  the incoming cable insulation outside the box).
		- A breaker or fuse for outside wiring that is near the bottom
		  of the breaker panel or in an add-on fusebox.  The outdoor
		  wiring may have been homeowner-installed after the house was
		  built, and was not buried deep enough or was done with the
		  wrong kind of wire.   

Subject: What is this weird stuff?  Old style wiring
	
	In the years since Edison "invented" electricity, several different
	wiring "styles" have come and gone.  When you buy an older home you
	may encounter some of this stuff.  This section describes the old 
	methods, and some of their idiosyncrasies.

	The oldest wiring system you're likely to encounter is called
	"knob and tube" (K&T).  It is made up of individual conductors with
	a cloth insulation.  The wires are run along side structural
	members (eg: joists or studs) using ceramic stand-offs (knobs).
	Wire is run through structural members using ceramic tubes.  Connections
	were made by twisting the wire together, soldering, and wrapping
	with tape.  Since the hot and neutral were run separately,
	the wiring tends to be rather confusing.  A neutral often runs
	down the centre of each room, with "taps" off to each fixture.
	The hot wire tended to run from one fixture to the next.  In some
	cases K&T isn't colour-coded, so the neutral is often the same
	colour as the hot wires.

	You'll see K&T in homes built as late as the 40's.

	Comments on K&T:

		- the people installing K&T were pretty paranoid about
		  electricity, so the workmanship tends to be pretty good.
		- The wire, insulation and insulators tend to stand up
		  very well.  Most K&T I've seen, for example, is in
		  quite good condition.
		- No grounding.  Grounding is usually difficult to install.
		- boxes are small.  Receptacle replacement (particularly with
		  GFCI) can be difficult.  No bushing on boxes either,
		  so wiring changes need special attention to box entry.
		- Sometimes the neutral isn't balanced very well between
		  separately hot circuits, so it is sometimes possible to
		  overload the neutral without exceeding the fusing on
		  any circuit.
		- In DC days it was common to fuse both sides, and no
		  harm was done.  In fact, it was probably a Good Thing.
		  The practise apparently carried over to K&T where
		  you may find fused neutrals.  This is a very bad
		  thing.
		- Building code does not permit insulation in walls
		  that contain K&T.
		- Connection to existing K&T from new circuits can be
		  tricky.  Consult your inspector.
		- Modern wiring practice requires considerably more
		  outlets to be installed than K&T systems did.
	
	Since K&T tends to be in pretty decent condition it generally isn't
	necessary to replace it simply because it's K&T.  What you should
	watch out for is renovations that have interfered with it and
	be cautious about circuit loading.  In many cases it's perfectly
	reasonable to leave existing K&T alone, and add new fixtures on
	new circuits using modern techniques.
	
	After K&T, they invented multi-conductor cable.  The first type
	you will see is roughly a cloth and varnish insulation.  It looks
	much like the romex cable of the last decade or two.  This stuff was
	used in the 40's and 50's.  Again, no grounding conductor.
	It was installed much like modern wiring.  Its major drawback
	is that this type of insulation embrittles.  We've seen whole
	systems where the insulation would fracture and fall off at
	a touch.  BX cable of the same vintage has similar problems.
	It is possible for the hot conductor to short out to the cable
	jacket.  Since the jacket is rusted, it no longer presents
	a low resistance return path for the current flow, but rather
	more acts like a resistance heater.  In extreme cases the
	cable jacket will become red hot without blowing the fuse or circuit
	breaker.  The best thing to do with old style BX is to replace
	it with modern cable whenever it's encountered and there's any
	hint of the sheath rusting.

	This stuff is very fragile, and becomes rather hazardous if
	the wires become bare.  This wiring should be left untouched as
	much as possible - whenever an opportunity arises, replace it.
	A simple receptacle or switch replacement can turn into a several
	hour long frustrating fight with electrical tape or heat-shrink
	tubing.

	After this wiring technique, the more modern romex was invented.
	It's almost a asphalt impregnated cloth.  Often a bit sticky.
	This stuff stands up reasonably well and doesn't present a hazard
	and is reasonably easy to work with.  It does not need to be
	replaced - it should be considered as safe as the "modern" stuff -
	thermoplastic insulation wire.  Just don't abuse it too much.

Subject: Where do I buy stuff?

	Try to find a proper electrical supply outlet near you.  Their
	prices will often be considerably better than chain hardware stores or
	DIY centres, have better quality materials, have wider variety
	including the "odd" stuff, and have people behind the counter that
	know what you're talking about.  Cultivate friendly knowledgeable
	sales people.  They'll give you much valuable information.

Subject: Copper wire characteristics table

	These are taken from the Amateur Radio Relay Handbook, 1985.

	We don't show specs for 8ga or larger because they're

	To calculate voltage drop, plug in the values:

	Where I is the amperage, R is from the ohms/1000' column
	above, and D is the total distance the current travels (don't
	forget to add the length of the neutral and hot together - ie:
	usually double cable length).  Design rules in the CEC call
	for a maximum voltage drop of 6% (7V on 120V circuit)

I have been reading and archiving rec.woodworking since its inception
as net.rec.wood back in 1984. Below are some of the topics that seem to
come up frequently.

1). Should I buy a table saw or a radial arm saw?

	Table saws work best for ripping. Radial arm saws work best for
	crosscutting, but are limited by their arm's length. Both 
	saws will perform both tasks. The radial arm is more adaptable for 
	non-sawing tasks. For instance, overhead routing, surface planing, and 
	drum sanding attachments are available for some radial arm saws. You
	can buy a disk sanding attachment for use on most table saws.

	Ripping on the radial arm saw is difficult because it is necessary
	to push the lumber under the motor housing.  This problem can be
	minimized by use of pushsticks and holddown wheels. Maximum rip width
	is normally limited by the length of the arm. Building a secondary rip
	fence on the other side of the table from the column will enable you to
	rip wider pieces, but the off-cut piece width is then limited. Radial
	arm saws are more prone to overheating during rips in thick wood since
	the teeth stay in the cut longer, unless you cut substantially into
	the table top and even then there is no place for the sawdust to exit.

	Crosscutting on the table saw is difficult because it is tough to
	keep a board much longer than 4 ft square to the blade.  This
	problem can be minimized by building a good sliding panel cutter. Some
	table saws have built-in sliding tables, and aftermarket sliding table
	attachments are available for most saws. A couple of saws have sliding
	arbors, enabling them to work as inverted radial arm saws. The arbors
	typically don't slide as far as the length of many radial arms (for a
	review of 2 of these saws, see the April 1992 issue of FWW).

	Both saws are capable of accurate work. The radial arm saw, with its
	cantilevered arm attached to a cantilevered column, is typically less
	rigid than the table saw, which usually have their arbor trunions 
	bolted to the table in a wide pattern. Worn arm bearing in radial arm 
	saws can also contribute to wander in the cut. In table saws, play of
	the miter gauge bar will adversely affect accuracy.

	Both table saws and radial arm saws need to be aligned to work
	optimally. There are more aligning tasks to be performed on a radial
	arm saw than on a table saw. Radial arm saws typically require
	realignment more frequently than table saw, perhaps because of the 
	stresses put on the cantilevered assemblies.

	Radial arm saws don't need as much space around them as table saws for
	performing equivalent tasks. On the radial arm saw, boards are always
	oriented the same way whether you are ripping or crosscutting, so you
	need space to the left and right of the	blade, and only as wide as the
	widest board you're cutting. On the table saws, boards are oriented at 
	right angles depending on whether you're ripping or crosscutting. Thus,
	you need space in front and in back for ripping, and to the left and 
	right as well for crosscutting.

	It seems to be easier to engineer and manufacture a table saw than a
	radial arm saw, which has more moving parts that must withstand large
	forces without deflection or play. It can therefore be argued that if
	you're on a budget, a cheap table saw may work better for you than a 
	cheap radial arm saw.

	Some people say the radial arm saw is more dangerous because the blade
	is exposed above the work surface, and because the blade's location
	varies as the cut progresses. Angled crosscutting is particularly
	dangerous since the blade is now cutting where one normally holds the
	work. The spin direction of the blade tends to lift the work off of
	the table when ripping, and can pull the carriage into the work
	(resulting in binding of the saw or serious injury to a careless
	operator) in the crosscut position. So-called "safety-blades" have
	a shoulder in front of each tooth, thus limiting the amount of pull
	generated and reducing these tendencies.

	Some people say the table saw is more dangerous because you can't 
	see where the blade is like you can with the radial arm saw. On the
	other hand, the blade is always in the same spot on the table. The
	spin action of the table saw's blade tends to keep the work down on
	the table, but it can also throw the work, and off-cuts, back at the
	operator.

	Both machines are very dangerous and should be treated with much
	respect.

	As with all tool buying decisions, you should consider your intended
	applications, both now and in the future. The general consensus is that
	if you're building things like jungle gyms, house additions, or trim
	work (moldings), a radial arm saw may be best. If you're building 
	things like fine furniture or cabinets, a table saw may be more a
	more appropriate choice.

	A number of people have reported that the addition of a motorized
	miter box to a table saw is a satisfying combination.

	Taunton Press publishes a softcover book titled "Fine Woodworking on
	The Small Workshop." It contains a number of articles on designing and
	buying equipment for small shops, but is geared to furnituremaking.
	The majority of the recommendations are for getting a table saw first,
	with one writer claiming a bandsaw is the first tool to buy.

2). Which type of dado blade should I buy, the dial (wobble type) or
the stacking (chipper type)?

	The wobble type is very simple to use with infinite settings
	between approximately 1/4 inch and 13/16 inch. It does not produce
	true right angle cuts because of the design. 

	The chipper type doesn't have the same infinite setting for width.
	You can achieve nearly infinite settings by adding shims with
	thicknesses of 1/32, 1/64, 1/128, etc.  It will cut a square bottom
	on the dado, but it will also leave 2 grooves on the edges of the
	dado. The reason for this is that the blades are slightly larger
	than the chippers.  The larger blades are to reduce the splintering.
	The blades can be reground to be equal to the size of the chippers
	at the possible cost of increased splintering. Some say the grooves
	are a benefit because they provide relief for gluing joints. 

	Many people claim that the wobble type is easier to set up.

	The August 1991 Fine Woodworking further studies the features of
	the various types of dado blades.

3). How do I cut the perfect dado if both types of dado blades have
shortcomings?

	Your best bet would be to cut it with a router.

4). Should I buy a Sears blurfl?

	Most people agree that the Sears stationary power tools sold today
	aren't the same quality as the Sears tools sold 20 years ago.  
	It can be argued that if you can't afford to buy a Delta, then
	you should be looking at one of the Taiwanese clones rather than
	looking at Sears.

5). Should I buy a Taiwanese clone blurfl?

	It depends on how much money you have. If you can afford the
	Delta blurfl you should probably get it. Buyers should be
	wary that not all Taiwanese clones are quality machines. The
	general consensus is that Grizzly has good quality control.

	It should be noted that some of Delta tools are now being made
	in Taiwan. One would hope that Delta quality control is better than
	some of the cheaper imports.


6). How do I remove paint?

	There are many ways to strip paint from wood.

	Paint can be removed by scraping and/or sanding.
	Paint can be removed by using chemical paint removers.
	Paint can be removed by using heat.
	Paint can be removed by sandblasting.
	Paint can be removed by a new product known as Peel-Away.
	Rumor has it that oven cleaner also works.

	If you know of another way to remove paint please feel free to pass
	the information along. 

7). Should I use a hot melt glue gun for my next project?

	The general consensus is that hot melt glue is not adequate
	for woodworking projects. However, hot melt glue guns can
	have a place in the shop. Many people like to use them for
	tacking items together such as when building forms or jigs.

8) Where can I get plans for the New Yankee Workshop projects?

	Plans for any of Norm's projects can be ordered for $7.50 from

        (project name)
        New Yankee Workshop
        P.O. Box 645
        Bedford, MA  01730

	Videos, which include a copy of the plans, cost $24.95 plus shipping
	and handling, from 800-272-0280.  Both the address and phone number
	are given at the end of each show.

	Most of the projects from the first two seasons are in the two
	New Yankee Workshop books.  For the workbench, one important
	dimension is *not* given in the book, though it can, I think,
	be calculated.

9) What is the best woodworking magazine?

	There are many good woodworking magazines. Two that are frequently
	recommended in this group are Fine Woodworking and Woodsmith.

	Fine Woodworking is a bit on the artsy side and more for the
	experienced woodworker. It does not get into the small details
	of a project.

	Woodsmith provides much more details for projects. Woodsmith is
	well suited for both the amateur and experienced woodworker.

10) What is a board foot?

	A board foot is a common unit used in the measurement of wood.
	It is equal to 1 foot length x 1 foot width x 1 inch thick.
	It should be noted that the thickness is nominal thickness.
	After drying and surfacing the usual thickness of a 1 inch
	board is 13/16.

	A board 10 feet long x 1 foot wide x 2 inches thick would be
	equal to 20 board feet.

11) What is the correct way to handle the glue squeeze out problem?

	Use the right amount of glue.  The (obvious) danger is a glue
	starved joint.

	 Wipe off the excess glue immediately with a damp sponge or paper
	towel.  This method gets mixed reviews.  Some claim the water-glue
	mixture will soak into the wood and show up when the piece is finished.
	Others say that this is not a problem.  The effectiveness of this
	method probably depends on the type of wood and finish that are used.

	Allow the glue to harden somewhat (1/2 - 2 hrs) and then
	chisel/scrape it off.  Some recommend removing the glue after it
	begins to film over.

	Either finish the pieces ahead of time or apply paste wax.  This
	should prevent the glue from sticking.  The problem with this is
	removing the paste wax prior to finishing.

	Use a plastic drinking straw cut at 45 degrees to scoop the glue
	out of the inside corner.  As the straw fills up, it can be trimmed to
	provide a fresh surface.

12) What books should I purchase to learn about various aspects of woodworking?

	Thanks to Ken Smith (kensmith@cs.Buffalo.EDU) for providing the
	ISBN numbers along with a couple of additions to the list.

13) How do I finish toys so that they are non-toxic?

	a.  Behlens Salad Bowl Finish.  This product has been approved by
	    the FDA for use on objects that will come in contact with
	    food.  It produces a nice, semi-gloss finish.
	b.  Any vegetable oil. Could become rancid after a period of time.
	c.  Walnut oil.  It reacts with the air and hardens into a true
	    finish.  It works particularly well when the oil is heated
	    and the item is dipped into the warm oil. Available at health
	    food or large grocery stores.  Don't buy the gourmet stuff!
	d.  Mineral oil or vaseline.
	e.  Water-based polyurethanes.  These are new products which are
	    very different from the more familiar oil-based
	    polyurethanes.  They are totally non-toxic, dry quickly, and
	    have no strong odors when applying.
	f.  Pure Tung Oil. It has no driers or solvents. It is essentially
	    just a vegetable oil but produces a nice finish that won't go
	    rancid. Use only Tung Oil that is "pure".
	g.  Rumor has it that shellac is also safe once it dries. I have
	    been unable to verify this.
	h.  Leave items unfinished.

14) What size drill bit do I use for a wood screw?

  Screw Gage    Shank    Shank     Pilot     Pilot

15) How do I finish the edge of plywood?
	a) Wood tape. It comes in 2 forms, one that can be ironed on, and
	   one that can be contact cemented on. The tape is approximately
	   1 inch wide, and can be trimmed with a plane, router, or knife.
	b) Glue strips of wood, either purchased or cut from lumber.

16). Which saw blade should I buy?
	There is an excellent article on evaluating carbide tipped
	sawblades in issue #72 of Fine Homebuilding (March 1992).

	To summarize the article:

	An expensive blade will typically last longer than a cheap
	blade and the cost difference is made up by the number of
	extra sharpenings available from the investment.

	A blade that has been tensioned will run truer and cost more
	than a blade that hasn't been tensioned.

	Carbide blades will last up to 60 times longer than steel blades.

17). Where are the archives for rec.woodworking?
	There are 2 archives that I know about.

	The first is ftp.cs.purdue.edu in /pub/sjc/woodworking. Currently
	it contains a list of Woodsmith plans.

	The second is ftp.cs.rochester.edu in /pub/rec.woodworking. Currently
	it contains summaries of past discussions of tools, some
	safety related notes, and some of the FAQ postings. Below is
	the current list of files available for ftp from cs.rochester.edu:

18). Where can I find cradle plans?

	1.  Garrett Wade
		$9.95 for plans for a "rocking cradle
		item number 14A03.SA in their 1993 tools catalog

	2.  The Woodworkers' Store
		$4.95 for plans for a "four post cradle"
		item number 40360 in their 1991-2 catalog

	3.  The August 1990 issue of Fine Woodworking has an article about
		making a cradle.

	4. Bartley offers a cradle kit for $199.  If it's up to the quality
		of their other kits, this should be good.

	5. Woodsmith issue #48 - cradle with frame and panel ends with
		arched-top panels.


19). Where can I find futon plans?

	1. TODAYS WOODWORKER JULY/AUG 1989, VOL 1 NO. 4
		Queen size futon folded in half length wise.
		Very attractive Futon sofa bed frame for queen size
		futon (possibly Swedish modern). Unfolds to make bed,
		breaks down for moving.  Elegant design with lots of
		mortise and tenon joinery.

	2. WOODWORKER'S JOURNAL NOV/DEC 1992 VOL 16 NO. 6
		"Standard" futon frame for standard 2 fold futon.
		Classic bi fold futon frame for queen size futon. The

		twin (39 x 75) and full (54 x 75).
		Plans are a large single sheet of blue print like drawings
		with associated text, construction looks reasonable and
		pictures of the finished project look good, but the plans
		are a bit intimidating

	5. Popular Woodworking SEP 1992, issue #68
		"Knock-Down Couch"
		Attractive Mission / Craftsman like design for a sturdy,
		knock-down couch. The plans are not specifically for
		futons but could be easily adapted to a single fold futon
		(might not need to be adapted).


20). Where can I get information about particle board?

	The following was provided by Stavros Macrakis (macrakis@osf.org)
	and was added to the FAQ with his permission.

	*********************************************************************
	For technical information on particleboard (PB), the National
	Particleboard Association puts out some very nice free pamphlets,
	which I summarize below.  Although they are basically addressed to
	industrial users, they cover particleboard joint techniques quite well
	for the rest of us.  Some of the facts about joints are very surprising.

	I've tried to summarize the essential information below, but you can
	also order copies from: NPA, 18928 Premiere Court, Gaithersburg,
	MD 20879.

	Specifier's Guide to PB and MDF

  	Abstract
		There are 15 ANSI grades of particleboard, with diverse
  	properties.  For instance, face screwing strength varies from 90-450
  	lb, stiffness from 80,000-500,000 psi.  Recommendations are given
  	for matching grade to use.

	Dowel Holding Strength of PB and MDF

  	Abstract
		Dowels joints are one of the cost common adhesive-based
  	furniture assembly joints.  Dowelling is a simple, inexpensive, and
  	reliable means of making butt and miter joints.  Joint strength is
  	largely determined by the holding power of the dowels.  Use good
  	quality dowels, diameter <= 0.5x the stock thickness.  The longer
  	the dowel, the greater the strength.  Holes should be 0.005"
  	oversized for edges, same as dowel on faces.  Use 60%+ solids
  	content PVA adhesive, applying glue to both dowel and hole wall,
  	with slight squeeze-out.

	Adhesive-based Corner Joints for PB and MDF

  	Abstract
		The thicker the panel, the stronger the joint.  Simple butt
  	joints' strength is limited by delamination; glue blocks or edge
  	banding help.  Dowel joints are standard, and work well; they should be
  	glued only at the dowels, NOT between edge and face (!).  Four dowels
  	for 18" are standard.  Biscuits have equivalent strength, but are
  	easier to align at assembly.  The strength of a well-made simple miter
  	joint without reinforcement (dowels, etc.) is generally comparable to
  	that of dowelled butt joints (!); dowels add little strength, but
  	splines and biscuits do.  Rabbets 1/3-1/2 the depth of the panel make
  	strong joints, but tend to split.  Dados are better, but less
  	attractive.  Rabbet and dado butt corner joints (= dado and tenon =
  	dado box corner) combine a dado on one panel and a rabbet on the other.
  	Dowelled butt joints are stronger (!).  Dovetails are excellent, but
  	require precise and time-consuming machining.  Molded polyurethane
  	joints (plastic splines) are as strong as or stronger than dowel
  	joints.

	Metal Fasteners for PB and MDF

  	Abstract
		Screws, nails, and staples are widely used.  Screws are
  	strongest.  The type of screw affects strength by only +-10% (!), but
  	PB screws are less likely to break.  Screw diameter affects strength
  	little, but screw length directly affects it.  Screw diameter should
  	not exceed 20% of stock thickness.  High internal bond strength PB
  	holds screws better.  Edge screws have half the strength of face
  	screws.  Use full-length pilot holes; shorter holes do not increase
  	strength.  Ideal tightening is 3/4 turn past flush on the face; 3/8
  	past flush on the edge.  Applying glue in the hole can increase
  	strength as much as 45%.
		Staples are used for attaching fabric, etc., and to hold glued
  	joints.
		Nails split panels, so should be >3" from a corner, and >6"
  	apart.  Ring shank nails hold better, plastic coated best.  Drive
  	them at an angle.

	Mechanically-based Corner joints for PB and MDF

  	Abstract
		Most bolt and cam joints are 20-50% weaker than dowelled joints.
  	Screw joints are comparable.  Plastic corner block units can be much
  	stronger in outward bending, but only comparably strong in inward.
  	Even when they are equally strong, mechanically-based joints are often
  	less rigid.  These systems are most useful for ready-to-assemble
  	manufactured kit furniture.

	Particle Shelf Systems (Builder's Bulletin #1)

		(not seen)


	All the above are free.  They also sell:

	Particleboard from Start to Finish $12.50

  	Abstract (theirs, I haven't seen this)
		Ten chapters (120pp) of useful information for users of PB.
  	Includes information on material handling and storage, sanding,
  	machining and tooling, laminating, wet finishing, edge treatments,
  	assembly and fastening, construction products, shelving and
  	formaldehyde.

	MDF from Start to Finish $7.50

  	Similar abstract, 42 pp.

Archive-name: woodworking/motors
Last-modified: 3/30/93

This article answers many of the frequently asked questions about electric
motors. 


Motors:

    There are many kinds of motors, but this article considers only two
    kinds used frequently in woodworking tool applications: universal AC/DC
    motors and single-phase induction motors. Universal motors have brushes
    and commutators and are used for portable tools like routers, skilsaws,
    and electric drills.  Single-phase induction motors have no brushes,
    run only on AC electrical power, and are usually found on stationary
    tools such as table saws, drill presses, planers, and jointers.
    There are exceptions to this: some stationary tools use universal
    motors.

    Horsepower:  Motor horsepower is the most misunderstood (and misused)
    electric motor rating.  Neither motor, universal or induction, produces
    usable horsepower unless it is slowed down (by applied mechanical load)
    from no-load speed.  For induction motors, this slowdown is called
    "slip", and the horsepower "developed" by a motor increases with slip
    (to a simple approximation).  This is why induction motors are
    typically rated at 3450 rpm (two pole motor) or 1750 rpm (four pole
    motor).  The rating speed allows for slip from the "synchronous"
    speeds of 3600 and 1800 rpm, respectively.  Universal motors do not
    have a synchronous speed, but have a maximum no-load speed that depends
    upon the voltage applied to the motor.

    Most motors can put out a lot more maximum horsepower than they can
    sustain continuously.  By forcing more mechanical load on the motor,
    slowdown is increased and so therefore is the output horsepower.
    Mechanically, horsepower is torque times rpm, and increasing the
    mechanical load means that the rpm is slowed slightly and the drag
    torque is increased to obtain more torque times rpm.  Electrically,
    horsepower is volts times amps, and by conservation of energy, the
    mechanical output horsepower must be balanced by electrical input
    horsepower.  Since the voltage is relatively constant, this means that
    as a motor is loaded, the input current increases.  But the electrical
    winding impedance has a resistive component, so that higher current
    means more power dissipated in the windings.  In fact, the motor
    windings heat up proportional to the square of the motor current.
    Except for specially designed motors, the current that a motor can
    sustain continuously without burning out its windings is a fraction
    of the current at maximum load.

    Unscrupulous vendors sometimes publish maximum "developed" horsepower
    to make their products seem more capable than they really are.
    Developed horsepower may be two to five times the continuous duty
    rating of a motor.  Such products should be examined to discover the
    continuous duty rating to compare with other, more conservatively
    rated products.

    When the talk is of developed horsepower, the meaning is "peak" which
    for an induction motor is typically the local peak of the torque curve
    near synchronous speed.  A typical induction motor torque curve is:

          |

          |
          |
          |                                                         .
          |__________________________________________________________._
                                                                     |
          0                   RPM                              1800 or 3600


    As you can see, the curve is very steep in the operating region and in
    fact, the observed operation is typically that once you load the motor
    past the local maximum torque, the speed jumps to the corresponding
    point on the initial portion of the curve or simply stops.  The actual
    operation depends upon the shape of the curve near 0 RPM.

    The Rated HP is typically the torque level at which the motor can be run
    continuously without exceeding the temperature at which the winding
    insulation beaks down.  Since there is thermal mass involved, you can
    operate the motor at higher than rated torque for less than 100% of
    the time and not exceed this temperature if the motor is cool preceding
    the run etc. etc.  etc.

    Typically, two motors with different rated HP develop different HP in a
    ration close to the same as the difference in rating.


    The story is somewhat different for a universal motor such as is used on
    most hand held tools.  In these motors, for a given input voltage, the
    torque goes up as the speed goes down.  The more you load them, the slower
    they run until they stall, at which point their torque is a maximum.
    In this case, the developed horsepower is a the point along the torque
    curve where the speed X torque is a maximum.  As with the induction motor,
    the rated horsepower means you can run the motor there at 100% duty cycle.
    Again, you can load the motor more and it will produce more torque but you
    may only do this on a limited basis.

    The final word is heat.  If you exceed the winding insulation temperature
    rating, you will fail the insulation and ruin the motor ( or pop the
    thermal cutout if so equipped). 



    Application areas:  Universal motors are compact, have high starting
    torque, can run at high rpm, and deal well with rapidly varying
    loads.  They are often used with triac or thyristor speed controls.
    This makes them ideal for portable power tools.  Single-phase
    induction motors are efficient, have a limited rpm selection,
    are relatively heavy and bulky, and are almost maintenance-free.
    They work well in stationary tools that run at one rpm or that have
    a variable-speed transmission.

    Voltage: Both kinds of motors are supplied in popular mains voltages
    (115 or 230) but only induction motors are supplied with winding
    taps that allow either voltage to be selected.  As far as the motor
    is concerned, there is no difference in efficiency when selecting
    either 115 or 230 volts.  This is because such motors have two
    identical sets of windings that are connected in parallel for the lower
    voltage and in series for the higher.  Neither connection results
    in the individual windings seeing a different voltage.  However,
    inadequate wiring can make a difference to motor operation, because
    higher current at 115 volts may give unacceptable wiring voltage drops
    in some shops or garages.  Some wiring voltage drop is expected and
    built into the motor rating.  Nominal pole transformer output (to
    your house) is about 120/240 volts.  Motors are rated for 115/230
    volt operation, which allows for 5/10 volts wiring voltage drop.
    More voltage drop than this can cause low starting torque and
    overheating at rated load.

    115 or 230 volt operation makes no difference to your power company
    either.  The watt-hour meter at your electrical entry measures watts
    regardless of the voltage used.  Your power company does not give
    you a single watt for free, and your PUC (Public Utility Commission)
    won't let the power company charge more than the legal rates.
    Watt-hour meter accuracy is a matter of law in most States.

    Current:  Motors have a nominal current rating which is supposed to be
    the current at rated horsepower and rated voltage.  A motor will not
    draw exactly rated current except in the unlikely circumstance that
    the voltage applied is exactly the rated voltage and the load applied
    is exactly the rated horsepower.  As a matter of fact, most woodworking
    tools spend much of their life spinning without applied load and drawing
    only a small fraction of nameplate rated current.  When the tool begins
    to cut, motor current varies widely depending upon cutting load.  In
    some tools which have relatively small motors, motor current may approach
    several times rated current as the tool is momentarily loaded close
    to stall or breakdown torque.  An exception to this wide variation
    would be something like the motor driving the fan on a dust
    collection system; such motors operate at about rated horsepower all
    the time because the fan presents a constant load.

    For both universal and single-phase induction motors, the full-load
    current is given by

        I  =  (746 * hp) / (eff * pf * voltage)

    where eff is efficiency, pf is power factor, and the others are
    obvious.  In AC systems, the voltage and current waveforms are
    (nominally) sine waves and may differ in phase from each other
    by an angle called the phase angle.  There are 360 phase angle
    degrees in one sinusoidal cycle.  Power factor is the cosine of
    the phase angle, and for motors this angle is normally between
    zero and 90 degrees, current lagging voltage.  In DC systems,
    there is no phase angle, and power factor is defined as 1.0.

    Typical values for single-phase induction motors running at 115
    volts AC are pf = 0.8 and eff = 0.9.  This gives a rule-of-thumb
    value for amps/horsepower at 115 volts of

          9 amps / horsepower

    This figure is probably OK for rule-of-thumb comparison of induction
    and universal motors or reasonability checks as long as you
    remember that it is based on typical values.

    If you are contemplating operating a 115 volt universal motor
    on DC, performance should be slightly better at 115 volts DC
    than it was on AC.  The proper voltage to use is 115 volts DC.
    This is because AC voltages are given as RMS values, which
    are their power-equivalent DC values.  The tool will actually
    endure less voltage stress under DC operation because the
    peak voltage experienced under DC is 0.707 times the AC peak
    voltage.  Switches and contacts, however, may not last as long.

    Starting current can be as much as ten times rated motor current.
    This is usually not a problem for the circuit breaker feeding the
    motor, because modern circuit breakers are typically rated to trip
    instantaneously at about ten times breaker nameplate rating.  For
    currents less than the instantaneous value, the breaker trips due
    to internal heater elements which mimic the heatup characteristics
    of the wiring the breaker is supposed to protect.  Since starting
    currents last only a second or two (unless the motor is jammed),
    motors usually will not trip circuit breakers on starting current if
    the breaker is rated at higher current than the motor nameplate
    current.  This may not be true if you start the motor on a circuit
    which is already loaded close to rating.

    A motor may trip your circuit breaker on time-overcurrent (the
    heaters) even if the motor nameplate current rating appears to be
    within the breaker rating.  This can happen if you continuously
    overload the motor; motor current will then be several times the
    nameplate rating.  There may be other signs of this.  The motor may
    become extremely hot (spit sizzles on the casing).  This is General
    Electric's way of telling you to slow down.

    Breakdown torque:  Single-phase induction motors, unless they are
    designed for torquemotor operation, have a "breakdown" torque rating.
    This refers to the motor torque-versus-rpm curve, which has a peak
    torque somewhere between zero rpm and rated rpm.  If the motor is
    running and load is applied, the motor slows and torque increases
    until breakdown torque is reached.  At this point, further rpm
    reduction causes a reduction of motor-supplied torque, and the motor
    rpm reduces rapidly to zero (it "breaks down").  This is why a saw,
    for instance, appears to suddenly stall as it is overloaded.

    Ventilation: Most motors have one of two kinds of ventilation: fan-
    cooled open housing, or totally enclosed, fan-cooled (TEFC) housing.
    In the former type, a fan attached to the motor shaft draws air
    through the internal parts of the motor and blows it out of
    ventilation slots cut into the motor housing.  Most universal motors
    are of this type because of the need to cool the brushes and to
    exhaust brush carbon dust and commutator copper fragments.  In the
    TEFC type, the motor housing is completely enclosed and no air
    gets to the internal parts of the motor.  Instead, internal heat
    is conducted through the metal housing to fins, where air blown
    by an external fan removes the heat.  Some induction motors have
    this kind of (more expensive) ventilation and they are often used
    in applications where excessive dust or flammable conditions exist.

    Drive gear:  Surprisingly enough, even though many people will look
    at motor horsepower rating, they often completely ignore the drive
    gear attaching the motor to its load.  The drive gear is often a clue
    to the real power rating of the motor-drive combination.  It's
    difficult to determine the rating of enclosed gears, but v-belts
    can give an immediate visual clue.  While larger pulleys increase
    a v-belt rating, a nominal rule of thumb is about one horsepower
    per 1/2 inch v-belt.  Two 5/8 v-belts on large pulleys may be good
    for 4 or 5 horsepower.  One small belt on a motor which "develops"
    3 horsepower is cause for some suspicion.  Actual belt drive ratings
    can be found in manufacturers handbooks (see Gates, for example) or
    in Machinery's Handbook.

    Motor Starters:  Motor starters are big relays mounted in expensive
    metal boxes with heater overloads matched to the motor they start.
    They serve two purposes: 1) The relay contacts are heavy duty and
    are rated for the motor starting current.  Delicate contacts, such
    as those on a pressure switch, will fail if used directly to
    start a large motor.  Delicate contacts are therefore wired to
    operate the motor starter relay rather than the motor.  2)  Wall-
    mounted circuit breakers are designed to protect building wiring,
    not motors plugged into wall receptacles.  If your electrical box
    circuit breaker trips before your motor burns up, it is incidental,
    not on purpose.  However, motor starters are designed to trip on
    heater overload before the motor they start burns up.

    How much horsepower:  This question is often asked and has no easy
    answer.  This is because the amount of horsepower you need depends
    upon your patience, your preferences, and the way you use the
    machine in question.  Here are some pros and cons.  A larger
    horsepower motor (and associated drive gear) has a thicker shaft
    and is typically more robust than a smaller horsepower motor.  It
    responds to overloads and hard cuts more strongly, and may not stall
    in your application.  It does not use very much more power, since
    electric motors use only power demanded plus some motor losses (which
    are somewhat larger for higher rated motors).  On the down side, the
    initial expense of the motor and drive gear is greater.  Higher
    horsepower often requires 230 volt wiring.  The motor and associated
    drive gear and mountings are heavier.  A smaller horsepower motor
    is cheaper, lighter, and may run on 115 volts.  For a careful worker,
    the torque supplied may be sufficient.  On the down side, the tool
    may stall more often and wet wood may be impossible to cut.  The
    drive gear may be less robust and may require more maintenance.  If
    the tool is operated in overload, the 115 volt circuit breaker may
    trip.

We (my wife & I) laid about 1400 sq ft of flooring in our log home
and used a couple of "persuaders" for this problem.  The best was
the good old pipe clamps we all use for our woodworking.  Wherever
the situation allowed us to lay a 2X10 across an opening to hold
the crank end of a pipe clamp, we clamped onto the tongue edge
of the offending piece & easily pulled it in with the clamp -- 
we ended up working with a 20 foot long pipe clamp by the time
we finished, but it worked great.  The other method that I got
from the Oak Flooring Inst's literature is a little "tool" made
from a couple 8 inch pieces of 2X4.  You hinge them together, 
end to end, and put some "teeth" of some sort on one end (they
showed using an old pointed can opener -- we tried nails, 
screws, etc.,).  In operation, you put the flat end against
your tongue (well the boards tongue then...), and make a little
bridge, digging the pointy other end into your sub-floor (pressed
down with one foot), and take your other foot to flatten
the "bridge", forcing the joint tight.  This obviously takes
two people -- one to stomp the persuader, & one to nail the
flooring.  We found the "pointy things on the board" didn't 
work very well, & ended up just putting a temporary 20d
nail into the subfloor (hopefully into a joist) to hold the
persuader in the right place for tightening the joint.  Crooked
boards were a pain to deal with, but both of these methods
worked & we now have a GREAT looking floor...

Have fun!

Somebody mentioned Eric Sloane the other day on this newsgroup.
I thought I would look through my stack of his books and post
some information for anyone who would like to know more. My purpose
here is simply to increase awareness of Eric Sloane, his books,
and his artwork in order to boost the value of the painting I hope to
inherit from my in-laws :-).

_Eric Sloan's America_, copyright '54, '55 and '56 by Wilfred Funk, Inc.
  (I assume Wilfred is the Funk of `Funk and Wagnalls' since they
   published this book.)
  ISBN 0-88365-648-5

	This contains three books originally published separately,
	_American Barns and Covered Bridges_ (112 pages), _Our Vanishing 
	Landscape_ (107 pages) and _American Yesterday_ (122 pages). 
	(Which explains the three copyright dates.) This book (these 
	books) have the most prose of all my Eric Sloane books, but 
	there are still lots of black and white drawings, and a few 
	color plates.

_Diary of an Early American Boy_, copyright '62 by Wilfred Funk, Inc.,
	108 pages.
  ISBN 0-396-08337-4

	This book is based on a diary found by Eric Sloane, covering
	9 months of Noah Blake's life starting in March 1805. Eric
	intersperses diary entries with his own commentary, and, of
	course, black and white drawings.

_ABC Book of Early Americana_, copyright '63 but first published '90,
	around 60 pages.
  ISBN 0-8050-1294-X

	Lots of drawings of implements and architecture, from Axe to
	Zax.

_A Museum of Early American Tools_, copyright '64, 105 pages.
  ISBN 0-308-70046-5

	Also from Axe to Zax, but only tools. The Commander is on
	page 85, the Beetle on page 30. (They've been mentioned on
	the newsgroup recently.)

_A Reverence for Wood_, copyright '65, 111 pages.
  no ISBN in my copy, LC number 65-25668

	All about wood, from tree to finished products. Better
	drawings than in Bruce Hoadley's _Understanding Wood_
	(still boosting Eric's artwork :-). Color plates of different
	woods.

_An Age of Barns_, copyright '67, around 120 pages.
  ISBN 0-345-25594-1-695 (Hmm -- the 695 is the price in USA cents --
			  do they need a new ISBN when they change price?
			  The ISBN is probably only 0-345-25594-1)

	History of Barns. Silos and Outbuildings. Tools. Construction
	details. Color plates of a number of different barns. Lots
	of drawings, too.

_Recollections in Black and White_, copyright '74, 64 pages.
  ISBN 0-345-25125-3

	A very short autobiographical sketch :-) of the author as
	an artist. Discusses his early life as a travelling sign
	painter. Mentions that he changed his name from Everard J. 
	Hinrichs to Eric Sloane when he left home.

_The Seasons of America Past_, copyright '87 by the Estate of Eric Sloane,
	150 pages.
  ISBN 0-88394-076-0

	A calendric look at early America, mostly farm life. It starts
	at the beginning of the farm year, March. (Which is why February
	gets the leap day -- it was the end of the year!) Some early
	American recipes, including one for `brown stain' which includes
	skimmed milk as a base.

The following books are mentioned as `other books by the same author',
but since I don't have a copy of any of them, all I can report is the
title.

_I Remember America_
_The Spirits of '76_
_Return to Taos: A Sketchbook of Roadside America_
_A Sound of Bells_
_Book of Storms_
_Eric Sloane's Almanac_
_Folklore of American Weather_
_Clouds, Air and Wind_
_Skies and the Artist_
_Look at the Sky_
_Don't_
_The Cracker Barrel_
_Mr. Daniels and the Grange_ (with Edward Anthony)
_The Second Barrel_
_Eighty: An American Souvenir_
_Eric Sloane's Sketches of America Past_

I guess I better start haunting used bookstores...

Aw, Patrick -- does ``Dictionary of Woodworking Tools'' have
drawings as good as those in Eric Sloane's books? (If so, I *really*
have to hit those used book stores.) :-) Eric certainly doesn't describe
the tools very much. For example, how do you use a zax to poke a hole
in a slate shingle? I would assume you need multiple light blows to avoid 
cracking it, but Eric doesn't say. Nevertheless, I enjoy looking through
his books.

However, I would like to know what kind of misinformation you see
in Eric Sloane's books -- perhaps via mail?

Gee, I don't know, but I've got to go home now and oil my router bits! 
Seriously, Trendlines is giving you a crock.  I've never oiled any
router bearings and never had a failure.  

Doesn't Trendlines have a satisfaction guarantee?  If so, return it, buy
a new one and see if you have any better luck.  Alternatively call your
local Porter Cable repair center and find out about your warrantee.  If
you don't know where your service center is, call 800-223-PART which is
the Delta/P.C. repair hot line.  They should be able to tell you what to do.
They might even just ship you a new bearing for the bit in the mail.

Subject: Delta 12" planer prices

With a new addition coming to our family shortly, I've decided building a
crib starting with rough cut cherry is a great excuse for a new planer.
After reading the planer discussions saved on an ftp site recently, I'd
like to buy the Delta 12" portable planer within the next week or two.

Who currently has the best deal on this tool including shipping to NY?
I don't have as many catalogs as I'd like so I can only get a couple of
prices right now.  Feel free to email if you don't want to clutter this
newsgroup.


Also, it looks like many people really like the Ryobi AP-10 10" planer.
I'd like to hear from those who compared the two side by side.

Thanks!

        While at the Anaheim show I talked with the Magna-set people
an mentioned I had problems finding top dead center of the jointer
cutters.  He told me how to find TDC and I will try to pass what he
said along.
 
        Hold a piece of wood with a straight edge (I used plastic) on
the outfeed table over hanging the cutter head.  Bring a blade up until
it just touches the wood and mark the spot.  Raise the end of the stick
without disturbing its position, and move the blade to the other side
of the mark.  Oce again move the blade up until it touches the wood then
mark the point.  TDC is between the marks.  I then used a square to 
transfer TDC to the fence, realigned the blades using the Magna-set,
and no more end snipe.
 
        Also At the Anaheim show I talked to the Poter-Cable people 
about a problem I was having with my 334 ROS.  The dust canister just
falls off.  It falls off wether or not I keep pushing it back.  After
a few minutes it just falls off.  This weekend I talked to another
PC rep and mentioned the problem to him and he said that the Anaheim 
show was the first they had heard of the problem and that several people
had brought it up.  They are working on it but if anyone else has the

  Here's a re-post of my plane theory scribblings, which I first
entered when I was doing my bad trip at Stratus. If anyone feels this
and part II are worth puting in the handtoold FAQ, be my guest.


  To understand fully the function of a plane, an examination of the
action that occurs at the cutting edge is necessary. For purpose of
example, a simple chisel will suffice since a plane is nothing but a
box, which holds captive a chisel, commonly at a 45 degree angle, or
pitch, to the wood's surface, and thrusts the chisel forward. The 
various tasks in which a plane finds common use can all be done by the 
chisel alone, the simplest of the single edge cutting tools. But, the 
sheer effort and skill required to keep a chisel on its course, along 
with preventing it from digging in, are all solved by the control the 
plane affords. Regardless, whether a plane or a chisel is in use, there 
is a common action that occurs at the cutting edge.

  Before the action of the chisel as a 'plane' can commence, the action
of the chisel proper must be understood. But to understand the action
of a chisel, it must first be recognized that the chisel is nothing but
a wedge, albeit the perfect wedge. The wedge proper, when driven into the
wood, forms a line of cleavage that follows the grain of the wood nearly
along its point of entry. There is nothing controlling the path of the
wedge, save for the parallel layers of the grain, which results in a
very uneven surface. The wedge doesn't cut the grain, it only separates
it with the force at the end of the wedge where it is struck, not at its
bevelled point.

  The chisel solves the eratic nature of the wedge by offering some
degree of contol over its action. This is accomplished by bevelling one
one side of the `wedge' only; the opposite side being kept flat. This 
flat side follows the path of its bevel since it is in the same plane
as its bevel. The bevel bites the wood, throwing the waste up its bevel
side, as the wedge does. Thus, the wood can be cut, instead of cleaved,
and a truer surface be made.

  The chisel's bevel influences the movement of the chisel as it is 
forced into the wood during its cutting action. The chisel moves in a 
line coincidental to its bevel, following from the back, or heel, of the 
bevel toward the cutting edge. It does this no matter the chisel's orien-
tation. A shallower bevel offers less resistance to the wood's surface,
and will yield a cleaner cut. A steeper bevel, obviously, offers more 
resistance, and often splits the surface, acting, in this case, like the 
wedge.

  A chisel held perpendicular to the wood's surface, aligned with a
scribed line, and then forced directly downward into the wood, will 
not only bite into the wood, but will also move backward away from the
bevel, jumping across the scribed line. This fact rears its ugly head
when a mortice is first started at its end lines, resulting in undercut
mortices.

  If the chisel is then tilted 45 degrees so that the bevel is now
facing up from the wood's surface, and the same force on the chisel as
before is applied, with the addition of a slight forward thrust, one 
of two things will occur; 1) the chisel will skip across the surface 
of the wood, if the tenacity of the wood is greater than the thrust
applied to the chisel - the chisel chatters; 2) if the downward force is
greater than the tenacity of the wood, the cutting edge will dive into 
the wood and either bind until it stops, or split if greater thrust is
applied, owing to the fact that the bevel is nearly perpendicular to 
the wood's surface and resists any forward movement of the chisel. In 
this latter situation, the bevel, with its tendancy to draw the chisel 
deeper and deeper into the wood, in essence, is attempting to separate 
the wood, like a wedge, instead of cutting it.

  This detrimental affect can be lessened by lowering the pitch of the
chisel so that the bevel is now somewhat aligned in the direction of
the thrust applied on the chisel. The bevel now meets the wood's sur-
face at an angle more acute than before, and lends assistance, instead
of resistance, while the chisel is thrust forward. The chisel can be 
assisted further by grinding a shallower bevel, making the angle of the
bevel still more acute. However, the chisel will still tend to chatter, 
or bind as the case may be, but these tendancies diminish sharply as 
the pitch of the chisel is further lowered. Once the chisel is laid flat
to the wood's surface, the finest control over it can be had; the chisel
excels as a paring tool in this orientation.

  If the chisel is oriented as before, at 45 degrees, but with the 
bevel side down, it should be apparent that the bevel side of the chisel
is now very acute to the wood's surface, and, thus, very much in
alignment with the forward thrust applied to the chisel. However, this
alignment is not totally in harmony with the thrust, for if it were,
the chisel fails to cut. The bevel still makes contact with the wood's 
surface at an angle that draws the chisel inward in unison with the 
forward thrust. If the chisel is drawn into the wood too deeply, the
chisel may be rocked back to lower its pitch, which then lowers the bevel 
angle's contact with the wood's surface further, causing the chisel to 
bite less than before, producing a thinner shaving. This rocking action 
is how a drawknife can be made to cut effectively. For the purpose of the 
common bench plane, the chisel, or iron, is commonly held at a pitch of 
45 degrees to the wood.

  If the chisel, in the same orientation as just mentioned, is rocked
back too far, the heel of the bevel will make contact with the wood's
surface and will overcome any chance of the cutting edge making a cut.
This can be solved by reducing the bevel angle in relation to the
pitch of the chisel; the shallower the chisel's pitch, the smaller the
honing angle. It makes sense theoretically, but in practice it fails.
The smaller honing angle reduces the amount of steel directly behind
the cutting edge, which then offers the cutting edge very little support.
The cutting edge will be very keen, but will chip and break whenever it
meets a knot, or a harder wood. The benefits of lowering the chisel's
pitch here, soon become impractical, so the chisel can be flipped over
where another benefit, explained later, is gained.

  Now it's proper to examine the action of the wood itself as it is
removed from the surface as a consequence of the chisel. As the chisel
is pushed at its handle, an appliaction of forward thrust propells the
chisel across the wood's surface, which then cuts the wood. The cut wood 
must be moved aside in order for the chisel to continue along its way. 
This cut wood, known as a shaving, moves up along the blade, in an arched 
shape as the cut progresses. The shaving gains leverage the farther up 
the blade it travels, a detrimental fact examined later.

  An additional downward force, perpendicular to the wood's surface, may 
be applied at the cutting edge to increase the depth of the chisel's cut.
In this case, the force required to bend the shaving, as it travels up the 
blade, is often greater than that force required to cut or separate the 
wood fibers. This results in a split in front of the cutting edge, which 
runs with the grain and usually deepens, stopping the chisel in its tracks.
In short, a very thick shaving results, with the chisel digging deeper
and deeper into the wood until the wood's tenacity halts the forward
motion of the chisel.

  Conversely, if the downward pressure is lessened, a thinner shaving
results, which can then bend easily without splitting the wood. The
shaving offers very little resistance at the chisel's cutting edge, but
the resistance is there nonetheless.

  With respect to the wood's grain, some beneficial and harmful actions
can be noted, especially when the shaving removed is thick. The risk of
splitting the wood is minimized by thrusting the chisel with the grain.
In this case, the shaving tends to break apart as it travels up the
chisel's blade, owing to the fact that as the shaving travels up the 
blade, the shaving's points of contact with the iron have their grain
oriented so that the grain points downhill from the pitch of the iron, 
toward the wood's surface. It is impossible for any sizeable amount of 
leverage to develop since the shaving will split along its grain farthest 
from the chisel's cutting edge, toward the top of the shaving where it's 
met with only the resistance of the shaving itself. Thus, planing with the 
grain will often defeat any leverage the shaving may gain during its 
formation, resulting in shavings that tend to curl back upon themselves
tightly. But, this is not always the case; woods with a tenacious grain
can present a problem here because the fibers adhere to one another
stronger.

  Pushing the chisel against the grain is another matter altogether. The
shaving here gains leverage the farther up the blade it travels, since the
shaving's grain is oriented just the opposite as described for a shaving
with the grain. As the shaving grows, and travels up the blade, the grain
is oriented so that the fibers compress against themselves toward the
chisel's cutting edge. As this compression grows in strength, it acts as
a lever where it exerts more and more force at the chisel's cutting edge, 
and ahead of it. This leverage builds continually until it can overcome
the wood fiber's adherance, which results in the wood being torn from the 
surface before the chisel can cut it. This is known as tear out.

  Naturally, this problem of tear out is something that can be avoided
in the perfect world where all grain behaves nicely; the rule of thumb
that states "plane with the grain" works in this fantasy land. Such is
not the case for those based in reality, where the grain dives, knots
live, and tenacious woods abound. This problem was solved by some unknown 
18th century `genius'. He (it may have been a she for all we know) dis-
covered that by immediately breaking the shaving, as soon as possible 
after it is cut, and thus compromising any inherent strength the grain
may have, tear out can be reduced considerably. The shaving's ability to 
build up leverage is greatly minimized, even when going against the grain. 
This invention finds its use on plane irons, as the cap iron, and will be
explained in greater detail later.

  The transition from a cutting action to a splitting action occurs
later if the pitch of the chisel is lowered. The leverage gained as the
shaving moves up the blade takes longer to build up and, therefore, be-
come detrimental. However, a chisel employed with a lower pitch to the
wood's surface requires a smaller honing angle, otherwise the chisel
will fail to bite the wood well in the case of the chisel bevel side up,
or will contact the heel in the case of bevel side down. But there is a 
drawback in this situation - the smaller honing angle will have less steel 
behind the cutting edge to lend it support when the bevel side is down.
This results in an edge that can chatter, due to the flexing of the steel 
at the cutting edge, or, more likely, frequent chipping of the cutting 
edge. To be used effectively, the chisel is then flipped so that the bevel
edge is up and the low pitch can be taken advantage of to reduce tear out.
Turning to the actual plane, a smaller honing angle, and grinding angle, 
can be taken advantage of here, as the plane offers support all along the
flat side of its chisel, its iron.

  There is yet another way to minimize the risk of tear out through the
use of a chisel alone. The wood is 'fooled' into believing that the pitch
of the chisel is lower than what it actually is. This is accomplished by 
holding the chisel at an angle skewed to the forward thrust applied across 
the wood's surface. Visualize a single wood fiber cut with a chisel moved 
in a motion that is perpendicular to it. The fiber must climb the chisel 
at the full amount of pitch in which the chisel is held. If the chisel is
skewed to this forward motion, the fiber does not climb straight up the 
blade, but, instead, climbs the blade diagonally. The path of travel is 
farther, but it is less steep, a fact that climbers surely recognize.

It will be in the FAQ if the FAQ doesn't wind up being too big.  If the FAQ
is too big the Plane section will summarize this and say that I'm willing
to email the whole thing on request.

  Now that the mechanics of the simple chisel are recognized,
various contrivances can be added to the chisel to regulate
its pitch, its depth of cut, its support, its thickness, all 
in an attempt to eliminate tear out.

  The first object to add is an iron fixed onto the chisel, 
on the opposite side of the bevel. As explained earlier, this
iron, the cap iron, breaks the shaving as it is lifted from 
the wood's surface thus reducing tear out by eliminating any
leverage gained by the shaving.

  Naturally this cap iron can't be fixed permanently to the
chisel, henceforth called the cutting iron or iron, due to the
fact the cutting iron wears from use. The cap iron must be free 
to move when the workman either needs to hone the cutting iron,
or when he wants to back the cap iron off of the cutting edge
a bit. 

  The distance at which the cap iron sits back from the cutting
edge greatly determines the kind of shaving the cutting iron
produces. With the cap iron practically on the cutting edge,
very tight, crisp curls result, with the likelihood of tear out
diminished due to the shaving's leverage being compromised
nearly as soon as the shaving is cut. For the finest smoothing,
this setting of the cap iron is prefered.

  Should the cap iron be set back noticeably from the cutting
edge, a coarser shaving may be had, but at the risk of tearing 
out the wood. This will all be explained in greater detail later.

  Next, a suitable method of securing the cutting iron is mand-
atory so that its pitch may be held constant during use, some-
thing that is very difficult to do freehand. This is commonly
done by a support that attaches to a base. This support, if
adjustable to the base, is called a frog; if non-adjustable, is
called a bed.

  The troublesome problem of chatter, a fact briefly touched 
upon during the chisel description, is something that presents
itself in other situations - those being a cutting blade that
is too thin in cross-section, a frog, and a plane of insufficient
weight.

  There are two general classes of cutting irons, the tapered
iron, and the parallel iron. The tapered iron thins in cross-
section along its length away from its cutting edge. These can
be, and often are, very thick at their cutting edge, making them
very useful while new, but problematic as the iron is re-ground
throughout its life. Parallel irons, on the otherhand, don't
taper in cross-section. They are the same thickness along the
entire length of useable cutting steel.

  Adjustable frogs can contribute to chatter when the cutting
iron is thin in cross section, as is the case for common Stanley
irons. The reason for this is due to the frog's necessity to
be adjustable; as the frog is moved forward, in relation to the
base, there becomes a small unsuported portion of the cutting
iron along with the never supported bevel. Though this problem
is usually insignificant in most applications, there are woods,
because of their tenacious grain, that present a problem for the
cutting iron to cut cleanly. The thrust of the iron cannot over-
come the wood's tenacity, and the cutting iron flexes backward
a bit building up tension on the wood's surface. As the thrust
continues forward, the tension between the cutting edge and the
wood either is overcome, causing the cutting iron to release its
tension making the iron jump forward, or the the iron embeds
itself in the wood and the force of thrust is overcome causing 
the plane to bind. This same action is noticeable if the iron 
attempts to take too deep a cut.

  A thicker iron is less apt to flex due to its mass, and can be
used on plane's equiped with frogs, though these planes rarely
admit thicker irons without some modification. 

  A plane that uses a bed to support its iron fully, like a common
wooden plane, nearly eliminates chatter, for the iron is fully 
supported, except at its cutting edge. Chatter can be a problem for 
these style planes if the iron is deeply set, usually because the
plane's mass, or the downward force exerted on it, is insufficient
in relation to the set. The workman will need to exert more down-
ward pressure, thus increasing the amount of forward pressure to
thrust the plane forward, in order for the plane to cut evenly with 
a deep set.
 
  Parallel irons are commonly used in planes of this design for the 
fact that no matter how many times the iron is ground, the iron's 
cutting edge will always remain constant within the as yet discussed
mouth. Unless the cutting iron is secured to a frog, tapered irons
will increase the effective mouth opening as they are ground. The
addition of an adjustable mouth can overcome this deficiency.

  Finally, tear out can be reduced with the addition of a bearing 
surface ahead of the iron. In the simplest of terms, the nearer the 
bearing surface to the cutting action of the iron, the finer the 
planed surface produced. The distance this bearing surface is situ-
ated from the cutting edge is known as the mouth. A plane can func-
tion without a mouth, or more properly, a mouth infinitely wide. 
These are, however, special purpose planes used only over small areas,
like in a stopped rabbet where a normal plane can't reach, and are of
little value for smoothing or putting a finish surface on the wood. 
These planes, called edge or chisel planes always have their bevel 
up, their irons seated at a very low pitch, and a very fine setting
all in their effort to overcome tear out.

  A plane with a mouth opening too small to admit the passage of
shavings is useless. So a plane must be designed with a suitably
sized mouth in order for it to be the general purpose tool and 
offer practical use for the workman. These common planes handle the 
vast majority of applications, with some tweaking of the frog, the 
depth of cut, and the position of the cap iron in relation to the 
cutting iron. However, these common planes were found to be in-
adequate in design for stubborn woods.

  Turning back to the cap iron, recall that the distance it is set
back from the cutting edge of the iron will determine the resulting
shaving's characteristics. The farther back the cap iron is set from
the cutting edge, the coarser the shaving will be as it is lifted
from the wood's surface. Here too, the iron's set, or the amount the
iron projects from the sole, will effect the shaving.

  Consider a cap iron secured so a fine shaving results; the cap iron
is but a hair's thickness back from the cutting edge. If the iron is
set fine, that is it projects from the sole the smallest amount 
possible to lift a shaving, the expected thin shaving will result.
But, if the iron is set deeper, the same shaving will also result, con-
trary to what might be expected. A thin shaving results here because
the cap iron prevents the cutting edge to penetrate the wood's surface.
In both cases of the iron's set, once the shaving is lifted from the
wood's surface, it is immediately turned back upon itself by the cap
iron. Very thin and wavy shavings, usually 3 to 6 inches long (they'd
be longer, but the weight of the shaving breaks itself due to its
thinness), are produced with this combination of cap iron position and 
set, and is the optimal setting for final smoothing of a surface.

  If the cap iron is set back a distance, say 1/8"-1/4", from the
cutting edge, the plane will produce long, continous shavings. When
planing with the grain, these shavings will be very tightly curled -
the shaving's grain, as it rides up the cap iron, assists the cap iron
as it turns or breaks the shaving back upon itself. If planed against
the grain, the shavings will have a slight arc to their length - the
grain's orientation, as it passes over the cap iron, works against and
resists the cap iron's attempt to break the shaving. Naturally, the 
plane's mouth must be a sufficient width to admit the shaving, or the
plane will choke. Regardless of the direction the plane is pushed in 
relation to the grain, the resulting surface of the wood, with the cap 
iron set back from the edge, will be of a lesser quality than that pro-
duced with the cap iron nearer the cutting edge.

  There is another combination of cap iron distance and iron set that
must be recognized - the cap iron is close to the cutting edge, and the
iron is set deeply. This combination is undesirable, since it causes 
the plane to choke. The shaving is immediately turned back on itself by
the cap iron, but is then interrupted by the bearing surface of the
sole ahead of it, the front of the mouth. The shaving can't curl, but 
instead collides with itself. As more and more shaving is lifted, the 
shaving's progress is further impinged, causing the shaving to pack
tightly upon itself. The plane's mouth becomes choked, and the plane
stops cutting.

  One other point about choking bears mentioning - a cap iron that
doesn't fit tightly against the cutting iron, along its full width,
will cause the plane to choke. Any opening between the two will permit
a shaving to lodge between them, and the same action as described
before will occur. Make sure the cap iron is ground straight and flat.

0.56l), sponge over the whole of the offending surface (stripped of course)
and allow to dry thouroughly.  Once dry, you will find awhitish deposit on the
surface; this is crystals of oxalic acid, whice can be brushed off (wear a dust
mask  eg. duhhhhhh)  VERY IMPORTANT next step.  Residual acid in the wood has 
to be neutralised with a solution of 1oz borax in a pint of warm water (28.35g
in 0.56l), sponged on and allowed to dry.  Afterwards, the surface will be 
fuzzy, due to raised grain, so give a very light sand before staining and 
finishing. eg.  This is important too.  When you bleach wood it only goes into
the wood a little.  I had a black water marked oak piece and  bleached it 
(with clorox)  and then sanded and got my black back :(  bzzzzt start over.

Two part wood bleach (Hydrogen peroxide)

Oxygen is, chemically speeking, an extremely active substance. When produced 
during a chemical reaction, it is so chemically active that it readily attacks
organic materials (eg. YOU) and metals.  This introduction to the chemistry of
these bleaches is important to remember, as it will determine the safe approach
to the use of what are HIGHLY dangerous substances.  The chemicals in the wood
that produe its color are highly sensitive, and by producing oxygen gas within
the wood by chemical reaction, they are attacked and changed to
near-colourless
materials.  This is termed an oxidation reaction.
  As their name implies, two-part bleaches comprise two chemicals.  One is a 
strong solution of Hydrogen Peroxide HPO (typically 100 vo.), and the other is
a strong alkali (either 2% caustic soda or 0.880 ammonia solution).  You can 
buy these chemicals individually from a pharmacist but they normally only sell
20 or 40 vol. HPO, but it is probably better to buy a specially formulated 
proprietary wood bleach (eg. I do A LOT of wood refinishing and have NEVER seen
this in a catalog or store).  

1.  Brush the first solution over the wood, taking care not to flood it, and
leave
for about five minutes.  This is the strong alkali, and on some hardwoods
you may be horrified to the the wood darken considerably (eg. espasially OAK!)
don't panic this is normal.

2.  Brush the second solution over the wood and leave to dry.  This is the
HPO and you may witness frothing after a few minutes.  Again, this is quite 
normal, as it is simply the oxygen being released from the peroxide - it may
even sizzle.  

3.  Leave for two or three DAYS to thouroghly dry out.  The wood will be furry 
due to raised grain, and there may be odd watermarks.  Gently wash down with a
week solution of white vinegar, and leave to dry for another day or three.  

4.  Gently sand smooth with a 320 grit paper, NOT TO DEEP.  

5.  Repeat if needed or you sanded to much. :(

O.K. remember this.  The alkali acts as a catalyst, or (speeder upper) in 
to release the oxygen from the peroxide which, after drying, is harmless;
THE ALKALI IS NOT GONE!!!  The vinegar is what neutralizes the catalist!

Now the MOST IMPORTANT PART.

1.  DO this outside! Or with 3 times more ventilation that you think you need.

1.  ABSOLUTLY wear eye protection.  ALWAYS.  I wear eye protection when I 
use my scroll saw.  I am serious!

2.  WEAR your stripping gloves.  I got some acid gloves that a buddy filched
from his Chemistry department.  They go up to my armpits.   

3.  Wear cloths you don't need anymore.  That ammonia is not so bad over the
counter. .880 is NASTY stuff.  So is 100% (vol.) Hydrogen Peroxide.

4.  Use a brush you don't want anymore.  If you use natural bristle brush
it will just dissapear.  

5.  DO NOT USE METAL CONTAINTERS!!!!

6.  If you pour these solutions back into their containers with impurities
RUN!!!  So do NOT pour the solutions back into their containers.  

7.  If you pour these two solution together we'll read about the explosion in
the paper.

8.  Use pyrex glass or plastic containers. 

9.  I got the solutions mixed from my chemistry dept at school.  When I was
done
I took what I didn't use back and PROPERLY desposed of them.

10. Label your containers WELL!!!!

11. Enjoy.

This all came from Complete Woodfinishing by Ian Hosker.  And me.
I would buy this book ($14.00) if you do any wood refinishing/finishing.

I'd like to make a couple of comments here, speaking as a chemist:
Jay A. Davis says (speaking about hydrogen peroxide bleaching):
>Oxygen is, chemically speeking, an extremely active substance. When produced
>during a chemical reaction, it is so chemically active that it readily attacks
>organic materials (eg. YOU) and metals.  This introduction to the chemistry of

If this were the case, wouldn't wood lighten as it sat in air, with about
20% oxygen (YMMV)?  The oxidant here is hydrogen peroxide, which is more
active than molecular oxygen (which, you note, is released during the
reaction--hence the fizzies, although there are other possibilities for
the identity of the gases).  It's attacking the color components, disrupting
the light-absorbing molecules.  

Secondly, let me urge that people *leave alone* 100% hydrogen peroxide,
even if they can buy it.  Treated with even a bit of disrespect, it is
a high explosive, and, I was told, requires a special permit to buy.  

I almost wonder if you mean 100%.  Common hydrogen peroxide you use for 
disinfection is 3%.  The stuff I buy to use in lab is 30%.  Either of those
are safe if handled properly, although the 30% stuff will raise some welts 
on your skin if you don't wear gloves.  I would predict that the 3% would
be too weak to work, but the 30% stuff ought to do plenty of bleaching.

One nice thing about both of these processes is that the products are all
quite innocuous, once the chemicals are used up.  The oxalic acid is converted
to carbon dioxide (CO2), and the hydrogen peroxide converts to water, plus some
oxygen.  The problem to the wood comes only from the catalyst added (acid or
base, which must be neutralized).

Summary:  don't use 100% hydrogen peroxide, and be plenty cautious with the
30% stuff.  It doesn't take long to lose an eye.

By way of personal experience, I tried two approaches to cleaning
up some T-11 siding on a barn I'm repainting.  I live in a 'moist'
area and mildew had blackened all the boards.  I tried some
expensive oxalic acid ($12/gallon) which foamed and fizzed but
didn't do much to lighten the wood.  I then tried some cheap
bleach ($1.25/gallon) straight from the bottle and this stuff
instantly took out the stain and peeled off all the grime.

I am NOT at all impressed with the oxalic acid.

The paint store recommended mixing something called "chlorinated TSP"
with the bleach.  But it was rather expensive as well, so I have
just stuck with the bleach from the bottle.

	I just ran across it in the stores the other day.. there is a
non-phosphate version of TSP (and the only kind available here in Oregon
because of a "no phosphates" law).
	With this in mind, I'd make sure I was getting the right stuff -- TSP
seems to have become a brand name rather than an abbreviation of a chemical
name.

	I've used the TSP with phosphate.. I'll second that it's caustic.
I use to use rubber gloves till it dissolved a couple a pair.  Then I gave up
on them entirely.. but was pretty wary about just how caustic the stuff was
since it *dissolved* the hair on the back of my hand!.  I was using it to
remove nicotine, dirt and (!) the gloss from semigloss paint, before
repainting.
	This stuff is a powerful cleaner, but I certainly wouldn't want to meet
up with it in a dark alleyway :-)

GarrettWade (800-221-2942) is having a sale on the Record 151
and 151R spokeshaves.  They usually sell for $21 each, both are
being sold for $30 through 12/31/93.  I can't vouch for the
quality but the picture shows a pretty reasonable adjustment
mechanism.  Don't buy one with a single screw holding the blade.
If anyone out there knows about these, let me know.  I'm being
tempted at this very minute (need a new toy!)

  Of course us handtool lunatics use them. They are wonderful tools that
go places a plane can't. They can be pushed or pulled and make round work
easier to accomplish than it otherwise might be. I also use them to rough
out work, clean up drawer bottoms (after the drawer is assembled), to 
chamfer, and other junk I can't think of right now. 

  They are tons of them out there, with many different designs geared for
particular trades. You can pick up used ones for $10-$15. 

  After I enter the Stanley plane crud, maybe you can persuade me to enter
the Bailey/Stanley series of spokeshaves. But, if you're in a hurry for
that info, don't hold your breath - I've got several hundred more Stanley
planes to enter. UGH!

	I bought a used spokeshave to make some drawers fit better and
have found that it is hard to live without.  The scraper and spokeshave
are 2 tools that I thought I would never need.  I learned once again
to never say never.

  For the umpteenth time, the Bailey name that is cast on the plane is a
tribute Stanley paid to the man who invented the plane as we know it.
Leonard Bailey made planes himself in Boston, and the markings commonly
found on them are located on the brass adjusting wheel, and will have 
"BOSTON" on them. Stanley purchased his plane business in 1869, and re-
moved their production to New Britain, CT, where they now make spiffy
garage door openers.

  I have parts for your plane. If interested send me fanmail, your first-
born, a Big Mac (with extra pickles please), some Milk Bone dog biscuits,
and a million dollars in small, unmarked, American bills.

New or changed material is marked with a "|".  You can skip to the
new sections by typing "g^|" in most newsreaders.

I will extend this from time-to-time as comments come in, or it
seems appropriate to add new stuff.  This is not formated as Q&A,
just as a series of points.

This is a summary of the "Crib and Cradle Safety" pamphlet published
by the Ministry of Consumer and Corporate Affairs, Canada.
The date on the pamphlet seems to be 1987.  I don't imagine that
it's changed much since then.  The pamphlet ID is:

	C&CC No 190 17342 B 87-07

>From what I've heard of US regulation, they're fairly close.

These are probably a good start when you're determining the safety
of an existing crib or are thinking of building your own.  When in
doubt, though, it is suggested that you obtain the latest applicable
regulations.  I've done my best to transcribe them accurately, but
I do not warrantee the accuracy or current applicability of these
rules.

The measurements in this pamphlet are metric.   I'll take a stab at
the conversions, but if there's a conflict, take the metric.
(for reference, you divide centimetres (cm) by 2.54 to get inches.
There are 10 millimetres (mm) in a centimetre).  Even if these
are a direct copy of the USA's (or vice-versa) people should be
aware that the actual US regulations will probably not be
exact conversions (eg: it's been rounded off one way or the other)

slat spacing: maximum: 6cm (2 3/8")  [This may seem unreasonably
narrow - no child that's likely to be at home is going to have a head
*that* small.  True.  But a child's body can often slip through
a gap only a little larger, resulting in strangulation when the
child's head gets caught.]

corner post protrusion (above rails/frame): 3mm max (1/8")

When the mattress support is at the lowest position and the drop side
is at the highest, the top of the rail must be at least 66cm (26")
above the top of the mattress support.

When the mattress support is at its highest, and drop side at lowest,
the top of the rail must be at least 23cm (9") above the top of the
mattress support.

Other rules:
	- drop side requires two separate positive and simultaneous
	  actions to release the side, and engages automatically.
	- there must be no gap between the lower edge of the end panel
	  and the upper edge of mattress support.
	- all small parts are firmly attached and able to withstand
	  a 90 newton (20 pounds) of force, pull or push
	- there are no split, cracked or broken, loose or missing slats,
	  or broken or missing hardware or screws
	- threaded bolt ends are either inaccessible or covered by
	  an acorn nut
	- mattress support mechanisms are firmly attached so that they
	  cannot be released with an upward push from under the mattress
	  support.
	- there is no mmore than a 3cm (1 3/16") gap between the mattress
	  and the sides or ends of the crib when the mattress is pushed
	  into a corner.
	- the labeling on cribs, cradles and their containers clearly
	  identifies the manufacturer, model number and date of manufacture.
	- all open holes are too small for a child's finger to become caught.
	- crib mattresses should be no thicker than 15cm (5 7/8").
	  They should be kept in good condition.  if they're too soft
	  or worn down in any area, a gap or hollow may be created where
	  a baby could become trapped and suffocate.

    Literature which must accompany the crib or cradle should:
	- state and show clearly how to assemble the product
	- contain a warning on proper use of the product, including a
	  statement not to use it if the child is able to climb out
	  unaided or, in the case of cribs, is taller than 90cm.
	
    Mattress support mechanisms:
	The mattress support mechanisms or hangers on some cribs may
	not be secure.  Check them by rattling the mattress support,
	thumping the mattress from the top and repeating the thumping
	on the support from the bottom.  If the support dislodges, your
	child's life could be in danger.  To prevent this, prop up the
	mattress support firmly from underneath, perhaps by using large
	boxes.

	[Ed note: when in doubt, bolt it together.  This one item is
	probably responsible for more deaths than all of the other problems
	put together]

Precautions:
	- Some people like to protect the mattress with waterproof sheets -
	  but these could hamper a child's breathing and should not be
	  used.

	  [Ed note: many new mattresses come with integral waterproof
	  coverings.  You should use a quilted mattress protector *and*
	  a fitted mattress sheet (cotton or flannelette) over top.]

	- bumper pads are used to protect a baby's head if he or she happens
	  pump it against the side of the crib.  Bumper pads come protected
	  with a plastic cover, which should be checked as often as possible.
	  If it's punctured or torn, it could be chewed or torn even
	  further, and a baby might swallow or inhale pieces of it and
	  choke.  A torn plastic cover also leads to holes in the bumper
	  pad, and babies have been known to stick their heads in these
	  holes and suffocate.

Pointers:
	- Always make sure that your crib is assembled strictly in
	  accordance with the manufacturer's instructions, and that
	  each component is properly and securely in place at all
	  times.
	- If you own a portable mesh crib, make certain that the drop side
	  is fixed very securely in the raised position.  Otherwise, the
	  baby might roll into the mesh pocket formed when the drop side
	  is not fully raised.  The baby's head or chest could easily
	  become compressed between the floor of the crib and the mesh
	  side and the baby could suffocate.
	- Never leave a baby in a crib with something like a necklace,
	  elastic, scarf or with a pacifier on a long cord...
	- People like to hang mobiles over cribs.  These should be too
	  far to be reached by a baby standing in the crib.

Building your own crib/cradle (not from the pamphlet)

Finishing:

Ideally, you want to use a totally non-toxic finish, because some children
tend to act like beavers....  The best solution is to use some sort of
edible oil.  Unfortunately, most of the vegetable oils (corn oil, sunflower
oil et. al.) take a long time to dry, if at all, and under some circumstances
will go rancid and smell and may cause a child some distress.  Three oil
finishes that are known to be suitable are:

	- pure tung oil (make sure it says it's *pure*.  Most "tung oil"
	  finishes are combined with metallic driers and solvents to improve
	  hardness or speed up the drying)
	- walnut oil.
	- Behlen's salad bowl finish.

It's recommended that you let these finishes dry for two weeks or longer.

Some of the standard finishes will dry to a non-toxic state, but this
will depend on the brand, and a long drying time.  This FAQ will make
no recommendations as to whether any are suitable.

Mineral oil can be used because it is non-toxic, but it never really
dries completely.

Materials:  Many woods can cause skin irritation or other problems.
If you stick to a domestic hardwood (maple, cherry, walnut, poplar,
pine, oak, beech etc.) and use a reasonable finish, the cradle will be
safe.  Woods to avoid without extra precautions are: most exotic
hardwoods (especially rosewood, teak), cedar, juniper (aromatic cedar)
and some of the less common domestics, such as Oleander and Mimosa.

  If all the parts are there, and nothing is broken, $75 is a fair price,
a bit on the low side, but then that's to your advantage.

  If you can wait until next week, I plan to devote one entire SB&G to
the #45, provided I can get the #39's-#44 finished for tomorrow.

Subject: metal plane questions
Lines: 41

I find, with a variety of Bailey-style bench planes, that if I follow
the standard advice for very fine shavings on difficult wood, and set
the cap iron as close to the edge as possible (about 1/32") and the
throat as close as possible, the cap iron collides with the top of the
mouth before the edge can protrude.  This seems to leave four
possibilities:

1.  Set the cap iron close, and open the throat as needed.
2.  Set the throat close, and move the cap iron back as needed.
3.  Compromise; use moderate settings on both.
4.  Forget about the throat, and align the frog with the base to
    minimize chatter.

Which approach should be used, for which types of wood?  Any general
rules?

There really was a fifth possibility:

4.  Grind away enough of the top of the throat so that the cap iron
    clears.

This clearly won't work; but raises another question.  The planes I have
all have the edge at a slight angle to the vertical, tilting forward
(away from the blade).  Wooden planes normally have the throat undercut.
What is the correct geometry for the front edge of the throat in a metal
plane, in relation to the iron, chip breaker, and lever cap?

A final question:  I have a cheap Stanley #4 (hardware store variety,
marked "12-204 Made in England") that I have tuned, and that works quite
nicely.  There are two annoyances remaining.  One is the plastic tote.
I started making a wooden tote, and realized that the only advantage my
wooden-toted planes have is appearance; none of them are particularly
comfortable.  It seems that a tote which swells to the sides in the
middle, and widens in profile toward the bottom, would be an
improvement.  On the other hand, I've never seen such a tote described
anywhere.  What are your opinions on the best shapes for plane totes?

The other annoyance is the plastic adjustment nut.  I tried the metal
nuts from my other planes, and they seem to have a different thread
pitch.  Any suggestions on sources for a replacement?

  Welcome to the reality of a general purpose Stanley plane. You've
found its physical limitations, and perhaps now can understand why the 
Norris style planes were made. Norris style planes were made for one
use only - to remove the finest shavings for final smoothing. Stanley
planes were made for a range of uses - from the roughest work, where
they can tackle any wood, to final smoothing, where most woods are
managable. It's the difficult woods where they fail miserably, without
any modification of them.

  A general rule for a common bench plane is that the frog's position,
cap iron position, and set are all related. Put simply, if the frog is
set all the way back, then the cap iron is backed off from the edge,
and the iron set a bit deeper, all of which help to make a coarser cut
when you want to remove a lot of wood. When you want a fine cut, reverse
everything - frog forward, cap iron close to the edge, and iron set
shallow. But, as you've found, there is a limit to how fine this latter
setting can be made. That's why Hock irons and books devoted to plane
tuning are out there for your consumption - to make a general purpose
plane something into which it wasn't designed, a finely tuned machine
capable of tackling any wood.

  There is no correct geometry. Various manufacturers made this to what-
ever was was easiest to allow a relatively fine set of the iron. All that
matters is there to be sufficient material ahead of the iron, to form the
mouth, and enough clearance for the cap iron. Since cap irons have differ-
ing curvatures across the many manufacturers, there is really no standard
way of finishing the throat.

  This is kinda like asking what the best beer is. Whatever tote fits your 
hand is the best. For you. Ohio Tool, Sandusky, and Disston made totes
shaped for right handed dudes, which are supposedly more comfortable to
hold. They have a flattened left side, and are shaped on their right to
a form for the closed right fist. I've tried them, but can't comment on
their comfort since I'm a leftie and anything in my right hand feels
odd (except scissors or a beer).

Nope, the pure stuff is non-toxic (though it doesn't taste very good).  It
builds up a beautiful finish.  One drawback to it is that it takes at least a
week or two for the first coat (which sinks in quite deep) to harden
adequately.  Failure to let it harden enough means that it later "bleeds"
out, causing a rough finish.  I haven't used polymerized tung yet--which does
contain solvents and driers--but plan too next time I have a project to
finish with oil.

BTW, I use paraffin wax on my cutting board.

	OK, OK, so I gotta get my .02 in..... I don't actually put any finish
at all on my cutting boards. Most woods are pretty good at killing off
the bacteria that cause problems in food, so why seal off all that antibiotic
power? I read a study (i don't remember where, but it was in some microbiology
journal) where a host of cultures were plated out onto new and used cutting 
boards of many different materials...The only ones that had little to no
bacterial growth/survival were naked wood....
	I usualy just use the cut off ends of boards from projects - I use
a board for a few years, and when its getting chewed up or cracked, I save
the end from another project....
	Softwoods are nicest to knives, but tend to die a lot faster. I tried 
some black walnut left over from some furniture making once, and it lasted
a long time - a housemate ended taking it with her when she moved out, but if
you put a quickie edge on a knife, it would take it off right quick....

I've built several cutting boards finished with Salad Bowl Finish.
None has ever cracked, nor have I had any other problems with it.
Works like a charm.

  Futon matresses are most frequently made with cotton filler, however
  manufacturers are exploring other fibers including synthetics to prevent
  the lumping.  Construction of the matress shell is also improving from
  the original without internal partitions to various designs with them.
  It seems to be very similar to the evolution of waterbeds which went from
  seasick-city to waveless.

  I have never slept on a futon, but I have done surveys for the industry's
  major trade magazine and the trend is going toward a better product.
  Manufacturers are also doing a better job with the woodworking.  Next
  time you are in a store selling futons, ask to see their lastest issue
  of Futon Life.  It is sent to over 15,000 retailers across the country.

  Tom, I had the set of the Norris a bit strong, so that's why there was
some tearout. With a finer set, tearout isn't a problem, as witnessed by
the tiger maple blanket chest top I showed you. That's what they're capable
of, when it's set optimally.

I know this subject has come up many times before, but here is a little
info. from the Dallas Morning News today:

                        SAFE CUTTING BOARDS

For decades, cooks have taken it on faith that plastic cutting boards are
safer than wooden ones, the thinking being that plastic inhibits the growth
of bacteria and wood doesn't.  But it just isn't so.  Microbiologists from
the University of Wisconsin tested cutting boards made from seven different
species of tree and four kinds of plastic.  They found that a good way to
get food poisoning is to slice bad meat or fish on a plastic cutting board
and then use it to chop vegetables.  Bacteria stayed very much alive on the

Seems to me that putting any type of finish on your cutting board may inhibit
this killing effect (if it is true, I'm kinda skeptical about guys who study
cutting boards for a living anyway, but hey, who knew?)

According to the research carried out at the University of Wisconsin, it didn't
make much difference when the plastic cutting boards were washed between uses.
Bacteria seem to thrive in the micro-slices in the plastic since water and
cleaners have a hard time penetrating such places.

Not so, the research was carried out (according to the articles) on at least
some unfinished wood.

Just anecdotaly, I have used a block of maple, untreated, for the last 20 years
to cut meat and veggies. It usually just gets a quick wipe with a damp cloth,
sometimes it gets passed through the dishwasher (doesn't look any "cleaner").
I'm still alive, and the only time I've ever had food poisoning was from a 
meal at a restaurant where they used plastic cutting boards for the prime rib.

go figure.

The results of this study were originally reported in Science News a few 
months back.  It was a good study, not 'flawed' as someone here reported.
All the tests were done on bare wood (unfinished), so there was no effect
from any finish.  I'll try and dig out the article.

I bought the Milwaukee a few months ago.  The 12V drill I think you're
describing is the 0401-1 with keyless chuck, 1 battery and charger.  Add the
metal case and it becomes the 0402-1, add a second battery to the 0402-1 and
you have the 0407-1.

First of all, I bought the 0407-1 (2 batteries and metal case) for $172 here
at a local hardware store.  I thought it was pretty low because the lowest
mail order price I could find was the same $172.

I love it, it's drill heaven as far as I am concerned.  

The keyless chuck will hold very well as long as you learn to give it a tight
twist.  BTW you can get it with a keyed chuck if you want (don't do it!)...

I like to stay away from posting about rechargeable batteries, it can be a
hot topic.  But I just leave the second battery in the charger until the
one in the drill starts to slug and then I switch.  The charger turns off
automatically after the battery is fully charged, so this works fine as
long as the drill is actually being used at least occasionally.

BTW, Milwaukee has a blanket 30-day no-questions-asked return policy for
full refund.

I've slept on one of those futon bed/couches which were dowel based
but didn't have my keyboard handy. However I did see plans and
special hinges on page 5 of the new catalog from the Woodworkers Store.
They can be reached at 800-279-4441 or 612-438-8868 and have a dozen
locations in the U.S.
The hardware is $32.95 a set and the plans $9.95.
The sliding action is all in the hinge and the back and seat are
two separate panels that hook on the hinge which mounts to the side frame.

Hope this helps. I haven't actually seen the plans or hinges.

to take a look at it, but the following information should be able to
get you going on the right track.

I don't have any experience with this company or with making my own
folding futon bed, but my fiance has a futon bed and a futon couch
that folds into a bed (I guess that could be a futon bed that folds
into a couch).  At any rate, I prefer the futon bed over the couch for
sleeping, simply because it is bigger (they are equally comfortable).
The folding couch is a good idea, but as a couch it has a major
shortcoming (IMHO -- not hers :) Anyway, the futon tends to slip off
the couch after it has been folded (and sat upon) for some time (I
guess this would be called futon slouch :)  Anywho, I have been
meaning to fix this for some time by adding small covers that fit over
the lower corners of the futon and attach to the frame to keep it from
sliding.  My fiance is very protective of her futon and insists that
simply flipping the futon over every once in a while alleviates the
problem (I disagree, but I have yet to add the straps so the problem
couldn't be that bad).  I don't know if the brand of futon you use is
important or not.  The two beds that we have are from different
companies and both are very comfortable.  I hope this helps you out
some.  Hopefully it made sense (it's late :)  Anyway, my point was
that futons are great.  Making furniture is great.  Put the two
together and you should be happy.  Whether these plans are the key to
that happiness, I have no idea.  Good luck.

Hi Paul. 

The wedge is used to remove the drill chuck from the quill. Place a 
piece of scrap wood (about 6" x 6" x 0.5") on the drill table, under the 
chuck. Extend the quill with the hand-lever to expose the elongated hole 
inside the quill (you may have to turn the chuck through 90 degrees). Insert 
the wedge, bevelled edge downwards, and strike the end of the wedge with 
your hammer. One sharp blow should cause the drill chuck assembly to drop 
out onto the wood scrap.

To re-install the chuck; place the drill assembly back into the morse by 
hand, locating the 'tang' in the correct spot as viewed through the hole, 
then lever the chuck down onto the wood scrap and firmly seat the morse 
taper into the quill.

Drill bits for all the larger sizes are available with morse tapers. Most 
drill chucks only take up to about 5/8", so beyond that size, drill bits 
with tapers are required. They are removed and inserted as described above.

Drew.

Over the years, I've collected (and discarded) several different grinders.
I use grinders for sharpening turning tools, putting hollow grinds
on chisel and plane blades, buffing and honing metal, and for general
metal-removal tasks.  I'd like to hear about what people think is the
ultimate grinder, or is there isn't such a beast, what combination
of two machines would be ultimate.

Here are some of my rambling thoughts on the subject:

The Delta (and similar) wet/dry grinders have a nice wet stone, but the
smaller dry stone spins at 3450 RPM -- to fast I think for any serious
sharpening -- although for general metal removal they're great.

It would be nice to be able to have a 1750 RPM aluminium oxide wheel
on one side of the machine and a buffing pad on the other, and have
variable speed for the buffer (at least).  

Belt sanders are another idea -- can these work for sharpening
turning tools as well aas chisels/plane blades?  Do you need to
mess with changing grits all the time, and how long does a belt
last?  

Is 8" always better than a 6" wheel?

How many HP are required?

What's the ideal machine?

P.S.  I know about and use water and oil stones.  No need to clue
me in to that alternative to sharpening.  In this case, I crave 
POWER!

Steve I own a fair assortment of these gizzmos, couple of bench griders,
1" belt sander and my favorite a Makita water stone.  The Bench grinder
in my shop is relagated to grinding the heads off bolts!

I use the belt sander for rough grinding and fine grinding (depending on the
need) any large cutting tools I have.  Lathe chisels fall into this catagory
I seems to do an extremely fine job.  I move between a 120 and 320 grit
belt.  Belt changes are easy and quick.

The Makita water wheel is my mainstay grinding / honing tool.  I have 3 wheels
for it (120, 1000, 6000 grit).  I use it for all my standard chisels as well 
as my carving chisels.  Typically I will go to the 6000 grit stone on the
piece I am grinding and then go to water stones to grind the secondary
bevel.

For polishing carving chisels I have an old 1/3 hp motor set up with a variety
of buffing felts and various polishes.

This combination seems to work well for me.

I truly do enjoy using the Makita water wheel, it is a bit of a pain to set up
and it can be messy if you forget to raise the splash guard but it does to a 
good job and the fear of burning a tool just does not exist (unless you run out
of water!).  If you do urchase this machine and intend on doing some heavy
duty grinding please consider buying the coarse stone as it will make your life
a lot easier.

Regards - Steve

Guess it's time to send out the answers to this question I got when I asked it.
I'll now thank everyone for their answers, and time spent. The futon is on the
drawing board, I'm taking all the plan info and input and a scetch of ones I've
seen and comming up with my own, as none were excatally what I wanted (ain't it
allways so? :-( )

	Fine Woodworking has plans for just suck a contraption.  Not sure of
the issue, but it was within the last year.  Looked nice, too...

   Dave, I seem to recall something like this in one of the Fine Woodworking
On ... series of books. I think it was in "Chairs and Beds" or was it "Beds
and Chairs"? It's something like that anyway. It may be of some use.

19). Where can I find futon plans?

        1. TODAYS WOODWORKER JULY/AUG 1989, VOL 1 NO. 4
                Queen size futon folded in half length wise.

        2. WOODWORKER'S JURNAL NOV/DEC 1992 VOL 16 NO. 6
                "Standard" futon frame for standard 2 fold futon.

        3. Fine Woodworking    July/August '89 NO. 77

I've slept on one of those futon bed/couches which were dowel based
but didn't have my keyboard handy. However I did see plans and
special hinges on page 5 of the new catalog from the Woodworkers Store.
They can be reached at 800-279-4441 or 612-438-8868 and have a dozen
locations in the U.S.
The hardware is $32.95 a set and the plans $9.95.
The sliding action is all in the hinge and the back and seat are
two separate panels that hook on the hinge which mounts to the side frame.

Hope this helps. I haven't actually seen the plans or hinges.

I don't know if this will help you or not, but I saw an ad in
this month's WOOD (October 1993) that seems to be along the lines of
what you are looking for.  The article is on page 25 incase you want
to take a look at it, but the following information should be able to
get you going on the right track.

I don't have any experience with this company or with making my own
folding futon bed, but my fiance has a futon bed and a futon couch
that folds into a bed (I guess that could be a futon bed that folds
into a couch).  At any rate, I prefer the futon bed over the couch for
sleeping, simply because it is bigger (they are equally comfortable).
The folding couch is a good idea, but as a couch it has a major
shortcoming (IMHO -- not hers :) Anyway, the futon tends to slip off
the couch after it has been folded (and sat upon) for some time (I
guess this would be called futon slouch :)  Anywho, I have been
meaning to fix this for some time by adding small covers that fit over
the lower corners of the futon and attach to the frame to keep it from
sliding.  My fiance is very protective of her futon and insists that
simply flipping the futon over every once in a while alleviates the
problem (I disagree, but I have yet to add the straps so the problem
couldn't be that bad).  I don't know if the brand of futon you use is
important or not.  The two beds that we have are from different
companies and both are very comfortable.  I hope this helps you out
some.  Hopefully it made sense (it's late :)  Anyway, my point was
that futons are great.  Making furniture is great.  Put the two
together and you should be happy.  Whether these plans are the key to
that happiness, I have no idea.  Good luck.
