[Roll bar advice]

There is no simple answer as much depends on the geometry of the tubes / load path. In some instances the twin tube design may be significantly stiffer than a single, while in others there may be no appreciable difference. Formal calculation against the design / perceived load cases will give you a clearer understanding.

Yes, I understand the geometry matters but I was just hoping to get an idea of the difference ceteris paribus

Hi, can anyone advise on how to compare a single tube to twin tube design with regard to diameter and wall thickness?

thanks

Hmmm, mine is the most reliable vehicle I have ever owned, is driven fast off road every day. It has shed a few bits that drop off and make it lighter but the treatment it receives would kill anything else, thinks I. I don't find the clutch heavy and nor do I find it particularly uncomfortable or unacceptably noisy except perhaps at motorway speeds. And yes, it still brings a grin to my face every time I get in. Now, where did I put my rose-tinted specs

Military bumpers have box section between the chassis rails. The outer sections are the same as standard bumpers, but they have flag holders. The centre of the bumper has a towing pin.

Sound familiar?

Not quite, no centre pin, no flag holders. Here are pics

I wonder if anyone can shed any light on the construction of my front bumper which is of different construction from others I have seen. The channel section is the same but some box section is welded inside this as well as some plates?
