  1. In the App Notes section about Wheels, Wheels, Wheels, you state: Use a sprocket for a wheel (but remember that uncovered sprockets are not legal so you will have to cover the teeth with something – perhaps plain old chain. Is it legal to use an uncovered sprocket as a roller to collect a ball, as long as the roller will never touch the carpet? I’m assuming the reason that uncovered sprockets are illegal is to prevent damage to the floor.

  2. Can we use the supplied crimp connectors as mechanical stops by crimping them on the end of a cable?

Thanks again,
Jason

Answer:

This is fine, assuming that you don’t damage the balls or rack either. We only have a limited number of spare balls. If you start hurting them, you will be forced to change your machine design.

Answer:

Perfectly legal.
