I'm thinking of converting my Jet mini lathe to variable speed. Several years ago I bought 3 dc motors with controller boards from Vega. I tried to use one when I converted a 6x48 sander to a wet sander for sanding the edges of glass. I got it to work but it didn't have enough power and stalled under heavy sanding pressure, so I switched to a standard motor.
The motors I have are listed as 1hp, treadmill duty motors. Vega was selling them for the purpose of converting lathes to variable speed, so it should work. But I have a question.
In general, without a motor curve or much other info, should I design the 2 pulleys so the motor runs at low, medium, or high speed to get the best motor performance during normal spindle speeds (600 to 1300 rpm)?
Thanks, Perry
