Urethane belting was a fantastic find. We've used it every year since 2008 for various mechanisms with no failures, solid core mostly 1/4". You can easily make your own pulleys cutting a 'V' groove on a lathe (no need to make a round groove, a V works great.)

One important hint: You should NOT USE A FLAME as the fumes from burning urethane are toxic. Use a heat gun (expose only the ends to the heat) or soldering iron. The ends will get molten, push them together in the corner of an 'L' angle and wait for it to cool. Start long, you can trim a bit out later if needed.
