Installed my DIY4X A-Bomb about 18 months ago and have finally reached the place in my build where I can add the tubes. I went back and forth with getting a bender but in the end knew that I wouldn't be using it all that much and it would just take up space in the garage.

I reached out to Kurt with measurements and angles for the wrap bars and stinger and he bent them up for me. Took some back and forth with numbers. Basically Kurt telling me "you really want that? Are you sure those numbers are right... etc etc". Ha ha. In the end he came up with something that would work and I got them a few weeks later.

they came exactly how I had planned it. I just wasn't sure what I was gonna do for the support.

First issue was to get the wrap bars mounted up and tacked in place.

The challenge that I ran into that I would run into during the whole thing, was my 140 amp hobart just doesn't have the heat to really get good bite into the A-Bomb. I ended up triple passing some of the welds to the A-Bomb and the are still not wonderful. But they will do, I got towed by the stinger the other night when my fuel pump died and it held just fine.

one of the toughest parts was just getting them up and held in place where I wanted them.

Once I had notched the stinger and welded it on, I started measuring on the support bars. My notcher sucks so I knew it wouldn't cut it for the support bars which were gonna see some pretty severe angles, so I just used a chop saw and a grinder. LOTS of grinding.

The first bars were easiest to do. The part I knew would be tough was making the opposite side match up. I was pleased with how it came out. I had to cut a couple more than once, but knew that I would be happier if I had it done right than skipped out.

you can see that my welds were a little cold even when the hobart was maxed out. I also need to speed up but I am self taught and these things take time!

All in all I am super stoked on how it came out. I still have some welding and grinding to do, but it looks exactly how I pictured it in my head. I wanted something that I could use my high lift on should I need to and this should serve that purpose.

Looks really good dude!!! In fact, that is almost exactly what I was going to try and do on my a-bomb when I was putting tubes on it, but my brother and I only had a HF pipe bender to work with and it wasn't up to the task of bending a harsh enough angle to what your stinger has (it would kink the tube pretty bad if we bent it that far), so we had to come up with a different design. And that's when we came up with what is on mine right now:



But I really like yours. My oldest brother (not the same brother referenced above, haha) has contemplated getting an a-bomb bumper for his rig, and now that I have access to legit bender we might copy your design. :cool1:
 
I must have stared at your bumper a hundred times when I was planning my bends. I always liked the supports that came off the a bomb and tried to do that with mine but not enough room. Still a big fan of what you have done with your truck
 
Haha, that's funny. There are times that I wonder if anyone even looks at my build threads (since nobody seems to comment on them anymore), but I am glad that you got some ideas by what we did on mine.

Its all about strength, and I think your design with all the support tubes you added will be plenty strong, and it looks killer!! :thumb:

I just sent some of your pics to my older brother to hopefully coax him into ordering an a-bomb and do this same thing to it. I know he will love your design. I am even wondering if Kert has the dimensions still of what he bent for you and could replicate it real quick and mail the tubes with the abomb? (Kert...what do you think?). That would be even easier for my brother as he has limited time to spend fabricating, so if it came as a kit and he could just bolt/weld it on, it would work even better. (I may have just came up with an add on package idea for the A-bomb Kert. Could have two different designs....Mine and 4wheelinfury's that customers can pick from......)

Either way....NICE WORK man :smokin2:
 
I think those outside bends should tuck under the fender tighter, other than that it looks good.

Kert sells caps for those open ends too.
 
I actually wanted them to flare out a little. That way if I do come up on a tree or rock, they will deflect away from the body like a rock slider would.

I know what you mean about the threads. I posted up so much stuff and not sure if anyone was ever watching. ha ha. My youtube channel is getting views so I know that there are people out there interested in it.

I must have read your thread front to back so many times. There is so much similarity in out builds, that I would reference yours before I did mine. For example, when I moved my axle forward, I knew you had the same axle, shackle and bumper so I knew what mine would look like before I moved it!

I have talked to Kurt about offering a kit for the A-Bomb as I think it would be a great addition for the kit. I am sure he still has all the same numbers from my bends as it wasn't too long ago.
 
Nice job on the build. Good looking rig.

I like the idea of the tube being angles out to deflect the front end away from an obstacle. I think it could be a grabbing point if something gets behind it and it could prevent you from backing up. My friend's exo-cage had a flair to the rock slider and the back edge left a gap by the B pillar. It was amazing how often it would snag on a tree when he had to reverse.

You might want to add a bit of tube back towards the body to prevent that.

Exactly.

It really need to tie to the frame to be anything like a slider. Theyll get bent right over into the body with any rock or tree scuffing.

This! It either needs more bend in those corners and/or those entire wing tubes could have been angled back to the fender more but overall I like the style very much. That kind of simple tube work really fits my personal taste. Good job.
 
i think the angle of the pic isn't helping much. It actually traces the factory body pretty well. Just seems like it flares out. But I hear what people are saying.
 
I do still have the drawings for the tubes so they can be reproduced anytime.

Both you guys Abomb creations are cool. That's the one thing I like about the Abomb the most. I find it interesting to see what people come up with to finish it out. There are so many out there that are still just the center and that's cool too. Whatever ya wanna do. I do like seeing these, guys that take the time to add their own touches and make it "their" bumper and not another one like it.

If you can, try and hold on to those drawings for a while and I will see if I can convince my brother to pull the trigger on an a-bomb and possibly have you replicate these tubes with it and mail it all at once. I know for him that would make his life a lot easier :waytogo:
 
I got the bumper painted.

This is a huge milestone for me. When I started this build it was a focus on mechanics as fab seemed so far away from my skill set. Now I see that I have built the bumper I wanted I get fired up. No it isn't perfect but I am stoked on it. And I built it (with bends from DIY4X).

Cheers man. Really fired up on how this came out. Big props to Kurt for helping me out with this. Hopefully this helps others. I know he still has my basic measurements.
 
You've done a great job with the whole rig!

and the snowball begins!

Kert makes some great stout stuff, and I like what you've done to finish it off, good looking truck!
