I'm interested to see if anyone has come up with a retrofit that will
motorize the the rack and pinion crack on a drill press. My specific
drill press is the Delta DP-350 which is a benchtop. It has the R&P
and I know some floor models do as well.
I'm interested in this as I have low hand and upper body strength and I
try and motorize and automate everything I can. I've not figured out
how to do this yet although I do have an idea.
My idea would be to use a DC geared reversible motor mounted either on
the head of the drill press or to the base that had a heavy duty
flexible drive shaft with appropriate couplings from the motor shaft to
the keyed shaft that the R&P handle fits on. That, and a switch
mounted up on the head.
Seems simple in my head but I don't know what sort of motor and DC
control to look for (it would need to be high torque VERY low RPM). And
I'm don't know where to look for the coupling shaft.
I'd appreciate any ideas you have on this. Please post or email
" firstname.lastname@example.org" if so,
I drilled and mounted a 5/8" nut to the shaft that the crank
handle mounts on. I did this because my auxiliary table
interfered with the crank. Now I can use a socket and
ratchet or speed handle. I might try to use my 1/2" right
angle, reversible drill with an adapter to fit the socket.
Thanks for the idea to power it.
either one has the ability to be changed to low speed, high
torque by reversing the right angle adapter. Mount it to
under the table and it would be very accessible.
They would probably be cheaper and easier to adapt than any
other type of drive system.
Let us know how you make out.
I think the site onlinereviews did a review of a counter weight system
that allows you to move the table with a minimal amount of effort.
Also I would think an air cylinder could be used to raise and lower the
I don't have a rack & pinion system on my DP, so I recently added a
cable (attached to the table) and a pulley (attached near the motor)
with some barbell weights on the other end of the cable to
counterweight the table. Not quite perfect, but a heck of a lot easier
than heaving up the table + auxiliary table + fence + clamps, and
trying to have a soft touch with that. Anyway, one of the things a
friend suggested when I was working on that was to get a winch from a
boat trailer or come-a-long, and then do the same pulley-cable thing I
did. From there it wouldn't be too hard to motorize the winch or buy a
motorized one, but even without a motor, a winch handle or come-a-long
should be easier to move than the little handle on your R&P.
