Talking Re: Bending a 4130 chromoly frame with heat question

The proper way to bend tube without getting kinks is to fill the tube area with sand, then heat and make bend. I do my bending on a bending table at work. Filling a bike frame takes alot of tapping and shaking to get the proper fill. Once it is filled, you can bend it into a pretzel with no kinks.
