That about does it for parts. The next step will be finding pulleys for it. The two shaft extensions are different diameters, so we'll see which one its easier to find pulleys for. I've was told I can go down to the local farm supply place and pickup hubs that you just bolt different size pulleys to, so I'll probably try that out. After I have that sorted, I'll look at mounting the motor.
