We've used material as thin as .050 and .063 in drivetrains, back in the days before mandatory bumpers (we had no bumpers, they lived).


As to tubular frames, how about this:http://www.chiefdelphi.com/media/photos/12949 and http://www.chiefdelphi.com/media/photos/12952 (same robot) - Chief Delphi 2000
It just takes a patient welder

This is a weld I did in college, but one of my students two years ago was welding soda cans together like this for fun in her shop class. It is certainly non-trivial, but definitely doable.
