   Tom.

   A word of advice about posting an email address in plain text in a forum message. Never do it!

   You are leaving yourself open to bots that crawl the web looking for live email addresses. Expect lots of spam, or worse in the near future.

   Something like

   "Tomtwentyfivefifty at comcast dot net (replace with real numbers)"

   disguises your address but gets the message out.

   There are several ways to make wooden pulleys. A lathe is the easiest way. You could use a built up pulley for slow speed applications. Two outer disks the same size, middle disk 3/4" less in diameter will give you a 3/8" recess for a vee belt.I have made cone pulleys for some machines. A cone pulley can be trued up in place. Run a belt on one diameter, true up the others . Then switch to the finished diameter and true up the first pulley you originally drove with.

   One more way is to bandsaw the stock as close as possible, then using a circle jig on a disk sander to define the outer perimeter. The vee groove if needed ( flat belt drive needs a slight crown from side to side) can be done with a router and straight bit followed with a champher bit to angle the sides. The router needs to be mounted vertically.The fence acts the bearing surface, 1/32" cuts against the rotation of the cutter is best.

   If the pulley you are making has a hub( recommended for a pulley over 2" diameter).The hub makes installing the pulley easy. Sometimes just a setscrew thru the hub is enough to hold the pulley. If you need a keyway, lay out the spindle bore and keyway location. Bore a small hole first for the keyway.The bore the spindle hole.The keyway can be squared up with a small chisel or rifflers. A machinist broach works better if you have access to one.
