I'm going to try my hand at building the chainup stand posted in this forum. Only problem i'm running into is figuring out how to bend the square tubing. I've thought about heating it up with a torch to bend but am afraid that will kill the tensile strength of the steel and make it vunerable to breaking at a bad time. Was thinking about tryin the sand trick I was taught with a brake line but dont know how hard it's going to be bending the tube by hand. Any suggestions guys?
