We made the pulleys ourselves using 2.25" acetal that we got pretty cheap from a company in our town. We have access to three lathes and eager students so it wasn't too time consuming. We cut them to length, turned down a groove in the center to fit the cord, bored them to 1/2", and then hex broached them.

Looking back I probably would have just done what 188 Blizzard did which was use the Colson wheels as their pulleys. https://www.youtube.com/watch?v=UOMRgVIzI0M

That's the stuff. We used the 1/4" round solid core tubing.
