Just me, my current speed is very slow and easily distracted.
Everything else I use is old and junky and wouldn't be worth the effort to put in a different drive.
Perhaps the exception would be the 1/3hp Atlas Lathe, but a variable speed motor would be just another layer of lipstick. And the DC drive would probably require extensive drive belt modifications since the original is designed for a 1725rpm motor. Meh.
Guess the drive will go into inventory and eventually, the dumpster. As in, "Wonder why dad saved this?"
