Daryl:  Thanks for the info.  I am not a machinists so I am guessing at some
of the terms but here are the dimensions of the gear as best I can tell.
Diameter of the gear minus the teeth is 1 1/4".  Teeth are each 3/16" high.
There are 20 teeth and each one appears to be 1/8" thick at the base with a
distance of 1/4" between teeth. The gear itself is 5/8" thick at the top but
it is dished so that the thickness is 9/16" where the gear meets the shaft.
It appears to be a streight spur gear as you call it since it is not
helical.  The reason the machinists said he could not make one is because he
said he did not have the "cutters" to make it.  I am assuming that cutters
come in standard gear sizes. If I can't find a replacement I guess I will
try welding the gear and filing the teeth.  Since the blower is a crank type
the gear goes slow.  Thanks again.  Chris Hubbard

Chris, 

A straight Spur gear is listed in the WW Graingers catalog.

as 16 pitch, .500 face width (thickness of the gear at the teeth), 20 teeth,
1.25 pitch diameter, (dia where the center of the teeth from each gear
contact) with 1/2" bore 
It also says 14 1/2 degree pressure angle (will not work with 20 degree spurs).

Grainger's is all over the country. If they aren't listed in your local
directory, their phone number for replacement parts is 1-800-323-0620. I'll
bet they can give you the nearest branch.  Tell them you're a small business
looking for new sources, you might even end up with their 3200 Page catalog
of motors, tools, parts, blowers, mat handling equip, etc.

>the gear goes slow.  Thanks again.  Chris Hubbard
