Re: Bumper Pics and Info
In a wreck, it probably would fold, but that is better than the frame folding. You would be suprised how strong the tube really is. I used to design semi-truck trailers, and we made our rear underride guards out of 1/8" tube, and they were made to absorb the impact of a car rear-ending the trailer. I did some destructive testing on some of these trailer bumpers, and it actually took a lot of force to bend the tubes. Quarter would be great, if my frame was also quarter inch, but I don't think my little 60hp flattie would do too well lugging around a 1/4" thick frame. In an accident I want the bumper to absorb impact, not transfer it to the frame. For off-road situations the 1/8" is more than strong enough. If you are interested, I could go through the math and give the specific reasons of why the tube is adequate, but I promise it would probably bore you to death.
