Here's a stupid question. I am making the intake for the Sandia forge and I am not pleased with the way my first set of tubes came out. I am heating them with a rosebud. What is the most effective way to get this done? I don't have access to a forge. The end product will be an oblong opening in a piece of 2" std bip. which is 9" long. mitered 90* to a round piece of the same size pipe. Thank you for the feedback. Kenny O
