I decided to put together a motorized armature rewinder as the task of rewinding to me was one I dreaded.

The device is powered by a small geared down N20 motor coupled to the arm drive by a driveshaft with a universal joint.

I can vary the speed and polarity as It is powered by a 10 amp variable power supply.

The toughest part was the counter and how to get it working. I used a small electrical counter activated by

a plastic strip mounted to the arm holder. I should now be able to wind a motor in short order.

Incidentally a stock 14 ohm arm has about 390 turns of #40 wire on it. I unwound one to find that out.

Seems to work pretty good in tests.

Pretty awesome! Will you be winding for yourself only or will some be available to purchase?

If all goes well I will do some winding for others.
