[GrizHFMinimill] Re: Power feed on X - my version of engaging/disengaging drive unit.

Forgot to add, the pots are 10K @ 2watts, about 1 1/8" diameter. For a speed control it would not be possible to wear one out electrically speaking.

I unsoldered them and removed the crimps to remove the pots, the wire wound pots are a lot bigger than the original pots. What I did is mount the small circuit boards out of the way on one side of the control box and ran separate wires from the board to the pot. Pot is placed in its original hole.
