I wanted to modify my lathe to cut metric threads. But it requires 7 gears. Of course none of them are commercially available. I don't really want to be in the business of hobbing gears, so I'm going to an electronic gearbox instead. The stock setup was a timing belt, so hooking up a motor is a lot easier than cutting gears. I am not positive, but I think you could switch back and forth with the gear train setup. Eric Keller Boalsburg Pennsylvania
