A good many years ago I saw the set up a guy used for his " Wrought "
iron fence business. He used a small electric motor ( about 1/3 hp )
which drove a worm gear reducer. The output of the reducer drove a
manual auto transmission. The square stock was dropped into a square
three sided socket on both ends, the switch turned on, turns counted
and switch turned off. They came out straight and with a uniform
spiral.

I want to spiral some small square stock. Probably 1/4" and 3/8" dimension.
What is the easiest practical way to do this? Hold one end in a vise and
twist the other with a crescent? How do I keep the whole thing straight, or
do I straighten it later? I want to spiral sections along a longer piece
rather than spiral the whole length.

And when I do want to spiral the whole length, will it spiral equally along
the length?
