I got another idea the other day, and I was wondering is anybody here has tried it. I have an old Delta Rockwell lathe that is running a 1/2 HP 1725 motor through a jack shaft and gets as low as 375 RPM.
It occured to me the other day that treadmills use 1 to 2 HP variable speed DC motors and come with speed controlers. I have somebody willing to give me their old treadmill and I think I am going to take it, and take the motor and speed controler out to try to use it for my lathe.
Has anybody else tried this? any luck?
