Thanks for the many suggestions. By far the coolest thing that we have found with a week's worth of play with this urethane belting is that no tensioning system is needed at all. The elasticity and friction between the belt and the UHMW pulley is terrific. Even when the belt looks slack, it grips the pulley and does not slip. We'll look at the side load issue and may go to the two belts from the drive shaft going to a single wheel as a fail safe idea. Since the belt is under constant tension, is that making the side loads more of an issue then in previous years when we ran the Kitbot and transmissions in very much the same configuration with ansi #35 rollerchain?
