![]() ![]() BTW, what size tube? what wall thickness? what material? EDIT: One thing I thought of.I've hand bent 1/2" diameter aluminum tubing by packing the inside full of sand.this was cold bent. I've bent some other things in the past using a bending jig/fixture I made form scrap and found one secret is to put slow but constant tension as your making the bend.too quick a movement and you'll surely collapse the walls. The only way to know for sure is to go out to your shop and try it. I think it would be difficult to bend at home even with a bend jig and heated up as the inside would try to wrinkle, or the outside/side walls would likely want to collapse. The manufacturers use what is called a mandrel bender which has a die that runs inside the tube to keep it from collapsing during the bend (they bend it cold). I've seen rear frame rails made of 2" x 3" rect tube bent to different shapes. I've never tried it, but it's fairly common in the auto racing industry. ![]()
