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?
