I have some 3/8" copper tubing that I need to bend at a tight radius. Like
2". I have the spiral bender, and another hand held type, but can't find
either. Next week, I gotta get organized. In the meantime what's the best
way to bend it? I've heard of putting it full of sand. If I do that, do I
bend it around something round, or just bend it slowly and cautiously?

I bent some 10mm copper tube recently into a tighter radius and used
some nylon rod I had about inside the tube. I do have Cerrobend but
didn't want to use it at the time. The nylon was just slightly smaller
than the ID of the tube and after bending I could grip the rod in a vise
and twist the rod out without too much trouble, the subsequent bends I
lubricated the nylon which eased removal.
