Want to create more speeds for your lathe, make it spin very slowly. This is what you need. Connect this between your motor drive pulley and the spindle. It's very elegant with a cast iron base, bronze bushings complete with oilers. The largest pulley is 10". The two step pulleys are compatible with most 4 speed v-belt driven lathes, but if not it's simple enough to hinge the platform. To use the large pulley you will need a separate v-belt. The last 2 pictures are not mine but added for clarity. I'm not real eager to sell this but if someone needs it, it's yours for $100.
