YJ bumper build question

I'm building bumpers for my YJ and need some advice. I'm using A 60 inch piece of 3/16 42 tubing and 3/16 angle iron for top frame mounts with 3/16 2 flat bar for the bottom mount. I made recovery tabs out of 3/4 x 3.5 with a 1 inch hole steel which I want to have welded by a pro (welder friend) onto the face of the bumper. Does that sound ok. I got a couple of pictures before I weld it together

when i build mine, i slotted the tube clear through and made the tabs long enough to come out the back to add more weld area... if you think about the weight of a stuck jeep and the amount of force... i tend to go overkill though...

Chad,
I'm hittin Easy Street on MUD TIRES!!!

I fine with my old school tow hooks on top. Those big bosses are fine for towing the Jeep behind a motor home or something, but I feel are overkill for a simple extraction nudge via strap. If I'm really stuck, my winch is used rather than a hard strap pull. While I'm giving you a hard time... Simply fabbing up a simple bar bumper seems way under imagined. Design something that wraps around the frame, not just a minimal bolt on.

Ok Ill paint some unicorns on it. But is it strong enough if I have to go through with the recovery blocks i need more steel bar. I just want it strong enough not to break. Show me a picture of "wraps around the frame"

I know you're well into your project, and it will end up fine. Since you asked though, I made this one a couple years ago. The unpainted photo shows the 1/4" steel 'box' that slips over the bumper, making the Jeep only 1/4" longer compared to no bumper. The only design points were, minimal rock climbing interference, tires as exposed as possible, protect the fenders, and hold the winch and hooks. The whole thing is held on with six grade 8 bolts, four for the hooks and two underneath below the hooks.

Looks good! I did the same for my 3/16" bumpers and after running the numbers of the weight of my jeep there was no notable advantage to extending the recovery points through the bumper to the frame. The 3//16" wall tubing will be plenty strong to pull your jeep in any direction if it's welded right.

Did you end up making slots for your shackle mounts or just welding them to the face? Im building a front stubby bumper right now.
