What isn't simple to make? If you have access to a lathe, simply chuck up a pulley and turn a groove. If you don't, a student can achieve the same results (although a little less pretty) with a file and some spare time.

What isn't simple to repair? You would effectively cut the teeth off the pulley in the center. So if you used a fastener with a .25 head on it, cut a quarter inch groove in the middle of the pulley teeth. The only thing that might fail would be a fastener and those are pretty easy to come by.
