Body Dolly made for convex/concave areas?

Do some looking up minimum bend radii vs. the different materials that can be used plus the material thickness. Tables are out there for looking up the info.

This and minimum flange length(s) assuming you are doing just simple bends and the strength of the material and flange length.

There are many ways of bending metal and each of them needs the information to meet the strength needed and this is true for both new materials and older materials. Welding has different limitations also.

Added info. By-the-way, I think I probably have mentioned it before but just for what it is worth, I was a draftsman and did draw plans for parts, assemblies and installation of parts and some new fasteners used in the assembly and installation for airplanes.

I had to be aware of materials such as different shapes and fasteners and their composition and structural requirements for forming and matching of parts, assys and installations which includes the strength(s) that fasteners (for example) need before clamping of parts together.

A lot of the information is on the web but be careful as some of it is/may be questionable. A lot of the information I was to use is supposed to be secret.
