Ok, this table
http://www.ebay.com/itm/332138282892?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT
is what I am looking at to frankenstein into a welding positioner. I was looking for knowledge or experience with one mainly regarding how smooth the crank rotates the table.
I am aware of what up to 300 amps will do to worm gears and bearings and I think I have came up with a way to mitigate that (by cutting down and lining the the table lock plates with copper and grounding through them....crude brushes).
I have a controller and DC gear reduction motor sitting here that wants to be put to use. The idea is to mount a #25 sprocket where the hand crank is on the table and drive that with a length of chain from the motor. The table is a 90:1 reduction ratio and the motor turns about 100rpms max. I am looking for a range of .5-2rpms. With 20 teeth on the motor and 10 on the table, I *think* I can get that.
Feel free to throw any ideas my way......Your ideas may be more skookumer than mine.
