I have broken my belt on a 9×20 lathe, recommended size Gates vm 710, but its far to small, I actually snapped it trying to put it on. Has anyone know the correct size for this lathe and a good place to buy from. Tried Quality Bearings but they sent out Z710 belts totally wrong shape. Problem with these lathes is the cost of replacement belts after a lack of concentration, and where to find one not at great cost.
