Motor from Menard's, axle from Northern tool, pulleys and pillow blocks from Axman surplus, belt off a Volvo 240, stand from Harbor Freight, buffing wheels from Stew Mac.
That axle, is that just a steel rod? It looks like it's threaded on one end. Did you cut those threads yourself? Sorry, it's hard to tell with the size of the photo...
What HP is the motor? Does it provide enough power to put any pressure on the wheels without slowing down? I need to make one of these - nice job!
You can probably find a 1/3-1/2hp motor on Craigslist for not a lot of money. That's what I use (1/3hp, an old GE motor that was made to run gas pumps), paid $45 for it.

There it is! That's my next project, (or second to next). Great job! Nice distance and clearance around the wheels. That's usually one of the 2 problems with off the shelf buffers. Size and too small a motor.
