I thought it would be interesting to find out what people do for slipping belts since this is a fairly common problem. You can obviously tighten the belt but that will affect play if it gets too tight and doesn't always solve the problem. Some people put a coating on the back side of the belt to prevent slipping. Auto stores sell a stick to stop fan belts from slipping but it depends on heating by friction to apply it. What solutions do you use? Ken Danckaert
