Just looking for ideas.
I just acquired a milling machine. One of those mill/drill machines.
It has a handle on the side of the head to wind it up and down on a gear rack. I am finding it to be a real major effort winding it up because it's so heavy. Even though it's geared quite well, around 5mm per handle rotation, it's still a struggle. To add to this, I can't get it to the top because the handle ends up way over my head and that's ridiculously awkward.
The force required to wind it up is approx. 8Kg @ 135mm (handle length).
What I need is a motor gearbox arrangement, like a windscreen wiper (worm drive) but stronger and more powerful. DC would be and advantage too for speed control.
The rack has 23" of travel at 4 TPI. That's 92 turns of the handle to get it from the bottom to the top. If I could fit something that does that distance in 1 minute or less I'd be happy. Of course I could fit extra gearing if necessary to obtain that power and speed.
Without spending too much (pensioner you know), what items have a thing like that so I can scavenge one.
