I'll keep everyone posted on this. I burned a lot of acetylene trying to heat and quench the tube to no avail so I'm going to try the press next. I ordered a large Vee block to try to avoid crimping the tube. My plan is to go slow and see how the tube reacts to the pressure. I figure I'll probably wind up having to push it slightly beyond straight and let it spring back. I can also use the torch in combination with the press if need be. I don't want to create a larger problem than I already have!
