Picket Twister

[KFCHambone]

Im trying to make a picket twister. I'm basically set on my idea of a gear reducer and a electric motor. My question is, does anyone know what kinda of torque it would take to twist .5 square stock? I'd be twisting lengths of 6 feet. I seen one on ebay for about 100 bucks and in has an output torque of 700 foot lbs. Any torque specs would be greatly appreciated. Thanks, Gregory

I built a human powered one. Its on my second floor and i can twist 16' pcs with ease. I just walk around the twister like a horse tied to a circus ride. Mine has a 3' handle and i use about 30" of it. It doesn't take much effort its more of tiring dizzy motion walking in a small circle because you have to keep pressure on the barstock until done. Someday i may add my 60:1 gearbox/motor to it if i did more with it but i can twist 10 or 15 parts 15" long in about 15 minutes...Bob

I made one using a old pipe threading machine. It is set on a bench I made with a adjustable tail stock,so I can make different lenght pickets. It will twist 1/2 to 3/4 solid square stock like butter. It takes less than 30 seconds to twist a 40" picket. Turn it on and count rotations.

Another gearbox/motor pic. I use this setup on 3 different machines so its portable. Its all bolted to a 3" angle so i just adapt the angle to my next project and line it up...Bob

I know you ask for torque specs which I can't help. A unit that puts out 700 ft lbs must have a v-8 engine on it. I made a twister some years back that may help you. If you click on my youtube link below...you'll find a video of my electric picket twister and other stuff.
