I just watched YouBoob about converting my lathe from ac motor to variable dc motor. I have a 1.5 hp treadmill motor I intend to use. Sounded like a good idea but after ordering the components I had some second thoughts. If I switch to a DC motor that will change my feed speed and thread cutting ability. Currently the lowest speed I can get on my lathe is about 575 rpm, if I remember correctly, with the AC motor. Is there a "work-around" for this issue? Should I just turn the DC motor up to match the AC motors speed when doing threading?
