Hi Mr. Key:
I did this
for my Unimat DB. Only I used the flexible shaft and a 8mm
socket. That way I could drive the cross feed too.
Also if you
add a second shaft to the motor you can have two speeds, in both
directions!

I just got done cobbling together a cheap power feed unit for
my Unimat 3. I used nothing more than an Erector Set motor and 2
of the pulleys that come with most sets. The 1 to 1 pulley ratio
actually seems like a nice speed. Can easily make multiple
pullies to add options for different speeds. You can use a
Unimat belt, too. Haven't tried it under resistance while making
a cut yet, but it should do well with light cuts. The video
looks like the feed is a bit herky-jerky, but that is just the
video - it actually feeds very steadily. Any thoughts?
