Very nice write-up and great pictures.

What's the RPMs of the motor you got? I need to motorize the head lift on my Enco mill also.

Thanks,
Ed

Ed,

The motor I used is 140 rpm. I think 200 at the top end would work great. Just make sure you have enough torque. My first motor was 1/12hp, 200 rpm but only 10 in-lbs torque and couldn't move the head even with two 100lb springs. I would guess anything over 30 in-lbs would be fine.
