Lathe mod
I changed the motor on my larger lathe to a 3-phase with a VFD, so I now have a variable speed lathe, adjustable from the front panel. Should have done it years ago.
I've also been unhappy with the accuracy of the 3-jaw chuck, so I ground the jaws and took the twist out of the bed. Final result is runout of 0.0004" over 13" (was about 0.015 before).
