VPI MOTOR PULLEY ??

info@vpiindustries.com

I went out today and bought a metal turning lathe so I can make my own pulley.......It seem that if you don't want to spend your life trying to contact somebody that doesn't want to be contacted, then you might figure out how to do it yourself.....Its given me another viewpoint on some businesses like VPI and PRO-AC ......Its OK to buy a 1000.00 turntable but don't trouble them with the small stuff.......I will make my own out of brass and skip the plastic VPI ones......  Will

autospec, let us know how that exercise turns out.  Seems a bit extreme to go that far.  Sure hope you have experience on a lathe, not an easy task for the uninitiated.

pmotz,
it's not biggie, but you gotta be very good with numbers and math.
all you need is the brass rod, good mirror scale caliper, micrometer and calculator(optional) and cut at least a few pulleys with various curve radius and barrel size +- few micrometers to ensure proper speed.
if going automotive machine shop, request also to manufacture few sizes with provided engineering draft.
 

And don’t forget the pulley will need to be bored for an "interference fit" on the motor shaft: (https://en.wikipedia.org/wiki/Interference_fit) If it won’t go on the shaft, or falls off it, it won’t matter how accurate the OD of the grooves are.
