Hi
Gang:
I built
a power feed for my Unimat with the motor from my Erector set.
I arranged the gears to have two speeds forward and back. To
connect it I used a 10mm hex socket to connect to the handknob
nut with the Erector set flex shaft. Worked great, but more
nuance to me than just turning the cranks.
If I
did it again I would use an Arduino with a stepping motor to
get full speed control. I think you could build one for less
than $50.
Carl.

The alternative approach is to drive the lead screw with something
like an electric screwdriver. No rubber bands or gears needed, and
I reckon most people have one or two of them sitting about doing
nothing most of the time. I binned a few last time I has a clear
up in the garage.
