Default Bumper build

Ok, I've been thinking about some bumper builds for my F-150 and here's one of them, an air tank for a rear bumper.it would go the whole width of the truck but I'm not really sure how to do it so it would look right. Any ideas?

How big are you thinking??

Why not just put an air tank up under the box and make some much less ugly bumpers.


I have only built one rear bumper, idk where my pics are, but heres a couple front ones.

How you guys like the bumper? - Great Lakes 4x4. The largest offroad forum in the Midwest

I don't want it huge, but I figured I could kill two birds with one stone this way

Makes sense putting pressurized air in the thing that is most likely going to take most of the impact if you crash.

How are you going to weld it? Are you using pipe or plate? If you are using pipe are you using end caps or plate?

Unless you are a certified welder and have a clue about how to do it correctly it is a terrible idea.

Would be cool if you could pull it off but I can't see building a decent looking bumper that is big enough to hold a worthwhile amount of air. Plus it must be sealed perfect and you must have compressor

The main problem is have is getting it to seal, I could figure out the compressor or I could just put a gauge on it, and fill it up with air before I leave home. And the only way that I could see it being a problem with the compressed air is if I smack down on a rock, and even then it would blow up, maybe just get a hole and let the air out, it couldn't hold enough to explode.

you are dumb. If you can't make it seal you have no business even doing it.

You have no clue either. If a cap or something came off it can turn into a cannon. There is more energy in there than what you think. I weld high pressure pipe for a living and I have seen the aftermath of explosions. Just think about if you took a bicycle pump and pumped it up to 150 psi. How much energy would you physically have to exert to do that? That is the same amount that would be coming out instantaniously. I wouldn't worry about a puncture as much as a failed weld.

watch a punkin chunkin video - it shows the power of what you're contemplating.

if you have to have oba on the cheap, get a hp steel 120 cu ft scuba tank, or power tank of some kind, or rig your ac compressor. Plenty of air whenever, and little to no risk maiming or killing someone.

I wouldn't be concerned with the metal, I would be concerned with the weld.

The weld will be fine, after its done I'm going to test it to make sure there are no leaks, I know the welder, haven't seen a bad weld from him yet.
