    Default Picket Twister

    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

    Cool

    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

    Default Picket Twister

    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.

    watch ebay and craigslist for pipethreaders.

    the old oster machines show up quite often.

    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.

    If you have a tractor, you can make an adapter for the pto, and put the stock in a vice on the other end.

    I would NOT do that unless you really gear down the PTO, barstock spinning at 540 or 1000 RPM would be *dangerous*
