So, the current project for my Chevy truck is to build a fuel tank for it.

I have the plans drawn up, I have the material (1/8" 5052) and I have everything else needed to go about building this thing.

The problem is, that I would like to bend the sides, instead of cutting and welding. I do not have a brake. I do have an Oxy/Acetylene setup, and I have thought about annealing it, so that I can make the bends. I tried this today, and did not have much luck.

The thickest material I have annealed prior, is .060 3003 H14.

Can anyone give me some pointers on what to look for? If I cant get it right, I'll end up just cutting and welding, but I'd like to form it if at all possible.
