home-made weld positioner or plasma circle cutter

[worntorn]

I made a weld positioner for doing circular tig welds. By mounting a pivoting arm on the base, I find that it works really well for cutting circles with the plasma cutter. Cost of the postioner was zero, all from junk under the bench. Power for the positioner is a small variable speed Makita cordless drill.

Here I have cut a couple of 18" discs (both at once with the little Power Ultra 205 multi)for a custom drum I have to build. The drum will go into a new machine being built for a large bakery somewhere in Salt Lake City.

Here is a link to a video clip of the cut http://www.youtube.com/watch?v=iI0qbNjLCHs

Looks like 28 amps is the setting showing there, not bad for cutting 2 at once (3/16" ea.) which is much tougher than a single thickness of 3/8".
