Well, you must be a stronger man than I am. The only way I could
possibly see doing that is where a bend has a couple of feet of
straight pipe on each side for leverage. It doesn't always work out
like that. If you ever get a chance to see the "Working with Tubing"
DVD by Ron Covell, he takes a piece of metal channel and sets a piece
of tubing in it raised up on some stands, maybe an inch high. He
claims the metal channel redirects heat from the torch back onto the
pipe. Anyway, he gets a section of tubing a foot or so long bright
red using an oxyacetylene torch. He just keeps running the torch
back and forth while turning the tubing a little bit. Maybe I can
get him to come over and give me a few pointers.
