    "This works dandy, I know because I plan on trying it."

    Worst advice ever.

    Since I am looking for a rear bumper, does anyone have any pictures or have actually done a rear tj bumper on the kj?

    Thanks for the tips! I picked up a used Lincoln Easy Mig 140 and have yet to use it. I really need to break this thing out but other projects and general lack of funds keep me from doing what I want to.

    Just curious, why do you think it's a bad idea? I'm not questioning your judgement just curious if it's a safety issue, fabrication issue, or cosmetic issue that leads you to say stay away from this idea.

    Considering it's a flimsy-ass bumper to begin with, and the fact that TJ owners give these pieces of crap away for a reason, it's a combination of safety and being an ass-ugly way to devalue the shit out of your Jeep and make it look like some Janky ass hilljack owns it.

    I'm pretty sure the ARB bumper is around 100-110lbs, so I would use that as a guide for weight. I would probably use 1/4" steel for the frame and maybe 11 gauge to skin it. I saw something about using steel and aluminum earlier on here. Be careful with dissimilar metals, they can corrode each other. Also remember to either use 316 stainless (not 304, it will rust), or if you're using mild steel you'll need to either powder coat it, or at least acetone prep it and spray...otherwise you'll start getting surface rust in a few days.

    Now I'm sure you guys all realize I know zilch about fabricating and usually have no idea what everyone is talking about, but I do have something to add to the bumper fab conversation :)

    I have seen many "island jeeps" (down here a jeep is anything that's open, squarish, and might have 4wd like sidekicks, sammy's, wranglers...) with bumpers made out of bamboo. Lightweight, attractive, all in all I think it's a great option. Not getting that anywhere near Mr. Darcy, but a valid construction material! :happy175:
