So my King 10X22 lathe is a traditional belt drive 110v single phase machine. Prying the belts off to change speeds gets old real fast. I know, they won WWII with belt drive lathes. I should just respect the heritage. But Ebay has all these cheap speed controllers........ The motor shops all tell me that there is no way to install speed control on a 110v motor. Has to be 3 phase they all say. I could easily swap out the 110v motor for 220v if that would help. Motor shops say no, but Ebay......etc. So I am thinking maybe a mechanical variable speed arrangement on the belts themselves? Sort of like a split pulley? Anybody have any ideas/experience with this?
