Group, I plan to mount my plasma cutter in a fixture in such a way
that I can feed 4130 tubing under it to cut saddles. The tubing
would rest on a receiver which would allow me to move it in and out
and also rotate it. I don't plan to follow templates, just silver
pencil marks the same as I do now when grinding the saddles. The
advantage would be that the cut would be perpendicular to the wall
(grinding and all rotating tools make feathered edges), it would be
very fast and much cleaner than grinding. Does anybody see any
reason why this would not work? Jerry
Sounds like a great idea Jerry. You could make paper templates using 3D and
transfer the curves to the tubing with silver pencil.

Jerry,
That will work great. I have had tubes laser cut using a 4 axis laser system
to do the same thing. The squared up edges make a far better weld. Even in a
manual system, you could do hard templates on a larger piece of tubing, and
clamp a guide pin to the part you are cutting. This would allow you to
replicate a cut very easily and make your parts very `. If you want
a drawing on how to do this, let me know.
