Thanks! I used MIG to weld and the tubing is 1/2" 16ga ERW, cheap and easy to find, Home Depot, Tractor Supply, etc carry short lengths that are overpriced....much cheaper to buy a 20' stick from a steel supplier. I packed the tube with sand (MUST be completely dry or a steam explosion is possible), heated sections with a MAP torch, then bent them around a big socket clamped in my vice...made a template out of coathanger wire first to get the bends right.
FWIW there is a good article on sand bending at http://www.rorty-design.com/content/sand_bending.htm
