Arthritis and the hand crank on my mill don't get along. I had made a temporary powerlift (3 years ago, Ha) using a leadscrew that worked well ( a little too fast) but it had one drawback. If the leadscrew ever fatigued and broke the head would come crashing down. My permanent solution is a worm drive gearbox. I didn't have any plans so I made the gears and then built the gear box around them. My design was dependent on the stock I have, the equipment I have, and the experience that I don't have. I'm a retired building contractor so I had a powerful 500 rpm paddle drill laying around and it made a suitable motor for the gearbox. A bit crude but the finished product works great and the 30 to 1 ratio goes just the right speed for my purpose.
