Rockwell Delta 46-111 Lathe, Part 4: Remote Control Pendent

A long overdue update. The lathe has been repainted, reassembled, the variable speed motor installed, and I've began working on a remote control pendant like those found on Robust or Vicmarc lathes.

Treadmill motors have a soft start feature so the treadmill must always start at the slowest possible speed, a good safety feature in a treadmill but not desirable in a lathe. Reportedly you can bypass the softstart feature on an mc-60 controller (most common type) by switching the wiper on the potentiometer. Unfortunately I am not using an mc-60 controller and switching any of the potentiometer wires individually does not stop the motor. As time goes on I will experiment with switching multiple wires at once and report back. As it sits now, the speed control works just fine but the little on/off switch does diddly squat. There is a main power switch on the lathe stand for cutting power to everything.

Switching the center wire to stop/start the motor, an idea that did not work.
