if you pack the tubing with clean dry sand and plug both ends the tubing won't collapse while you heat and bend it around a form. if the tubing is 1/16" wall a peice of 5/8" round welded in both ends should work, it has to be packed very tight. i just made hinges for my car using 5/8" stainless tubing and bent them around a much smaller radius.
