Sorry this is out of order... it was an afterthought, and I wanted the chart for .065 wall first since it's most common.

Thanks, SportsCarDesigner and Cheapracer. These are helpful. The .049 chart is particularly revealing. Thinner wall, larger section = less weight, less twist; I knew the concept, but the figures are impressive.

Hi SportsCarDesigner, That is great info but I'm so ignorant I'm not sure I fully understand the implications. As I understand it "Torsional" applies to a twisting motion e.g. holding one end of the tube in place while trying to rotate the other end. If that is correct how does torsional strength apply, if at all, to bending force e.g both ends of the tube supported and a weight suspended from the middle? Does higher torsional strenght relate to higher bending resistant? I'm not sure I've even expresssed this in a way that makes sense. :?
