One trick is to make a collet that can be chucked in the three jaw. Make it out of whatever round stock or pipe you have. Turn a bore just a thou or so bigger than your sheaves with a shoulder inside a little shallower than the width of the rim. Then slit one side with whatever you have that will make a clean cut. The slit will allow the collet to squeeze the sheave when the chuck is tightened. I whipped up a quick pic with my CAD program but it isn't making it easy to post it.

Jared,

That does make sense. I may have to try that.

Since you are going to have the center hole in the pulley, why not put a bolt and nut thru it and hold onto it when you turn the second side of the pulley? This works as long as you make sure to really tighten the bolt that you are putting thru the center hole and take light cuts with your tooling.
