Box Section Wall Thickness
I am about to order the box section tubing for my chassis but where I work there are loads of off-cuts of 25 x 25 tubing which, unfortunatley, is only
1.2 mm thick.
Are there any areas of the chassis where this could be safely used or should I stick to 16swg as per the book.

My whole chassis is made from 1.2mm! There is plenty of tensile and compressive strength, most use 1.6 because it's a lot easier to weld.

im sure you would save enough weight that you could strategically add more tubes to get strength back where required, and still save weight overall.

Thin Wall Box
The main problems you have with using thin wall is getting loads into it. For example suspension brackets. You can not just weld straight onto the
flat of the box. You have to spread the load using reinforcing plates and by spreading the load over a few members and into edges.
