[TowerTalk] motorizing my winch

[Bill Heinzinger]

I have a 2000 lbs hand powered winch manufactured by Thern of Winona MN.
It has a oil filled gear case with the kind of gears that hold it's
position.
What I mean is that what ever position the crank is in it does not
freewheel.
I forget what kind of gears those are called.
It does a great job raising my old Wilson 55 ft rotatable.

The only problem is that it takes 25 turns of the crank to make 1 rotation
of the drum.
That's a lot of turns from nested to full extension.
The though of removing the crank and placing it with a motor has crossed my
mind.

Anybody done such a mod. I think it should be a small gear on the motor
shaft and a large gear on the winch crank shaft if my high school physics is
still with me.

Anybody have any ideas?
I've got the steel, welder and skill to fabricate a mount.
Need a reversible outside proof motor though.
