Rear bumper materials

[MattF]

Would an aluminium 1-1/2" or 2" tube make a suitable rear bumper, strength
and resilience wise?

Never said there would be just one. What is the minimum wall thickness
one would need for a usable aluminium tube with enough strength?

bear in mind the grade of alli as well, some are more maliable than others, some could be prone to cracking with a bump!

I can't weld for toffee, so I'd try to find some other way first. No idea, yet.
I always brainstorm as I do a job, so I usually only have a vague idea initially.
The job usually dictates the method as it progresses. I never was any good at
pre-planning.

And nobody could say Surfenstein didn't end up on the right side of perfection. It's usually better 'cos you don't end up with the specific mindset of it having to be done in a certain way. It makes it a lot easier for working around unexpected problems, doesn't it? The purist planners hate it though.
