Joe, there is another way to make the jets.  Locate an old furnace,
canibalize the orfices  ( or is it orfose) braze the hole shut and re drill
with a number 60 bit, or 57.  The bits are available at hobby stores, but
hold your breath...a collection a little bigger than a golf ball will run you
about 30 bucks.  Natural gas orfose :-) are too big for propane, you'll have
fuel all over the place if you get the wrong size.  Experiment with hole
sizes, or ask your dealer what size they're supposed to be.
    My local propane supplier had no trouble selling me two, at a buck fifty
each.  I threaded the gas supply pipe, screwed them in then silver soldered
solid, after a trial run to see if it worked ok.  Discovered I needed one
size larger orfice for the one farthest downstream.  Merely drilled it out
with one size larger bit, works like crazy.  Those bits are little more than
hair, but have patience, you'll win.   Enjoy.

I need a flat belt pulley with a 1 1/4 inch bore.

Thanks.

I just drill my orifices in a brass pipe fitting. I think I use a #68
or #70; I need to measure my forge. Use a drill press at high speed
and feed slowly and carefully.
