Lathe Question

Darn near "anything" is better than nothing. So long as it's not "cutting oil" LOL I used to have an Atlas/ Craftsman 12" and got rid of it when I got a SB. Not sure I gained much. The SB is I think a 9" I had subbed an old style (simple) treadmill motor on the Atlas which had a simple speed control so it was completely controllable for speed and direction.
I put a treadmill motor in my Craftsman 12" band saw. I can slow that puppy to a crawl to cut metals now. I kept the digital speed controller on it so now when I want to slow it down. I just dial in 3MPH....:-) I have it 5:1 reduced too, turning a 10" pulley. I'd still like a little more oomph as it still seems to labor on some material. Blades are probably shot.
