Build a jig from a old car wheel or brake drum,lock it in a vice,heat your tubing cherry red .you can weld one end to the jig.Start bending.Easy as pie.HD P.S.Fill your tube with sand it wont flatten out.

fill it with sand first to keep the kinks out.

And pack the sand very, very tight. Have you thought of trying an electrical conduit bender. They're cheap and available at most hardware, home improvement and electrical supply outlets. 1 1/8" O.D. is close enough to 1" conduit.

Make sure the sand is super dry before you pack the tubes and don't seal the tube completely. You need to leave a slight leak so that when you heat the tube, the air inside can escape as pressure inside the tube rises from the heat. Wet sand will steam and cause the same problem if you don't allow the tube to breathe.
