All depends on what is done, there are very simple techniques to make a flexible sheet stiff.

Won't a stiff sheet crack under stress rather than a flexible one? During flex, the left and right parts of the body will bend in opposite directions. A flexible sheet will twist and reform to original shape. A rigid one will resist bending until a critical stage after which it will either give way at the welding joints from the body or crack itself.
Am i correct? Quote:
Observe the roofs of vehicles and you will understand, moreover you will have to add strengthening ribs for added strength. Incorporate gutters for water drain.

Please elaborate how many ribs are required? On the phone behram said to make a frame using hollow 1" x 2" square pipes to make the frames and then weld the sheets over it.
Can you give a schematic of what the frame would look like. Eg: a square first then maybe and X pattern inside? Quote:
Aluminium is also a metal. I understood though.

Lol. Ya sheet metal steel. Quote:

I'd love to have a concept like that but it's not possible to do. I've many times toyed with the idea of bringing down the tub of a CJ7 or some other Jeep body so that i can get direct bolt on hard tops and other fittings for it. The cost factors are prohibitive though. Quote:

as a result you see cracks in the rear tail gate side and under the front doors.
a roll cage internal or external straight to the chassis at 6 points can reduce this chassis twist to tolerable limits,
but then you compromise on articulation |
True. Let's find a solution. Quote:

And yes, it is made out of metal sheet. |
Nice to hear that. But i think the gypsy flexes less than the jeep. I may be wrong though.
What is the chassis section of a gypsy? C or box?
