modified stock bumper
 
This is my first write up so be gentle.:D Alright I have been wanting to get a shorter bumper for a while and since I do not like the idea of spending alot of money just so I can have a name on my bumper I decided to modify my stock one. I cannot find a picture but when I bought my Jeep my bumper was bent right in the center so I found the center of the bend and marked it in the front, then I took my speed square and put it on the back and slid it down till it lined up with the center point then did the same for the other side and the bottom. After that I had my measurement so I cut out the wedge I just drew and bent the bumper back straight and welded it up.
I only measured things to make sure each end was the same, I also made a card board pattern just like the frame and cut and taped it together to make sure it looked ok. Now that the thing was straight I measured the frame on the front and decided I would add 3/4" on both sides just for looks, measured out some more wedges and bent each end, you will see what I mean in the pics but that is how I got the ends to angle back incase you could not understand my dribble that is the same way I straightened the bumper.
Once I got the ends bent back I cut the angle off the end and used the scrap I had cut off to cap the ends, welded it all up and took a grinder to it to smooth out the welds then used a 60 girit paddle wheel then a 120 grit paddle wheel to make it pretty.

and after it was welded and ground down.

and after I hit it with a little primer to keep it from rusting but I think I'm going to bed liner it.

sorry for my other reply I used the wrong code and it took me so long to fix I could not edit it.

very nifty, i like it. i wish i was that talented at fabrication but i just havent had enough practice.

no problem. i took care of it for ya :).

broken-fish 03-03-2010 11:16 PM

thanks that was all done with about $180 worth of tools compaired to the $489 I saw one for sale the other day.

P.S. I love harbor freight and thanks jgano

yj-genral 03-04-2010 10:55 AM

thats not a half bad idea. looks good man.

InfernoGirl 03-04-2010 11:54 AM

It does look good! Nice job! :D

oldman 03-04-2010 11:58 AM

that is a nice job. you have talant

broken-fish 03-04-2010 02:52 PM

Thanks for the compliments. Once I find a pipe bender I can use I would like to add a stinger style brush guard, and I am looking for a 1/4" plate so I can add a winch plate. But I am quite proud it turned out better than I thought it would

Find a tube bender instead! use tube instead of pipe.

I would use either probabely, but considering I could bend the pipe with a cutting torch I would use whatever I could get ahold of. Also I might be just flipping it backwards but isn't pipe way stronger.

Pipe is made as pipe where as tube was just flat stock curled into a tube and sealed up where you can see the seem creating a weak point?

stobob1 03-04-2010 08:56 PM

What tools do I need to do this. I have friends with tools and I have been looking at doing something like this. Im thinking grinder, welder, but am I missing anything? I have never "fabricated" and this looks like my first attempt!!

jgano23 03-04-2010 09:10 PM

tube is better. pipe is measured by the outside diameter so wall thickness is inconsistent which creates invisible weak points. tube is measured my inside diameter so wall thickness is consistent throughout the length. there are different types of tubes.

broken-fish 03-04-2010 09:19 PM

Not everything I used is necessary but here is a list. Cardboard, sharpie, speed square, tape measurer, welder, and grinder (grinding wheel, wire wheel, cut off wheel, and a couple paddle wheels)

I would suggest making a pattern with cardboard or something, and depending on how well you trust yourself you don't even need to pull off the bumper but I suggest that you do. I actually only had one bolt come out I stripped the other 3 and groung the heads off.
one of the other nuts that's part of the frame came off due to rust, so once I rust proof the front I am just going to weld it on.

Thanks jgano I always get lost in the tube/pipe terms.

stobob1 03-04-2010 09:54 PM

Sounds great. Thanks!

broken-fish 03-04-2010 10:33 PM

yep no problem the hardest part is deciding which angles you want

First you said you were going to get a pipe bender, now you are going to use a torch, use whatever you need to but pipe was meant for water and sewage, tube was meant for structural applications, just make sure you cut the threads off of the end so no one can tell.:)

broken-fish 03-05-2010 11:07 PM

The reason I said it the way I said it is because I have neither a bender or a torch so if I am needing a tool I do not have I would rather use the easier one, being the bender. But I plan on buying a torch before a bender so if that happens before I find a bender I will just use the torch.

Frankly I do not care what the technical jargon is I am going to use something in a cylindrical shape and bend it however I can. strength is only prefered not necesary since I probabely wouldn't actually use the stinger anyways I just like the way they look.

nice job man!

Bignuke 03-07-2010 05:13 PM

nice

Blazin420 03-07-2010 06:06 PM

that looks phat i'm thinking about doing something like that

mcgyver1467 04-09-2010 05:12 AM

Thanks
 
Thanks for the idea. Heres how mine turned out. Before and after shots. I didn't have any channel or square tubing around, so the factory bumper re-make was the way to go. I added 1/4 inch plate to the inside for strength.

Before...........

Thanks. Its a work in progress. I have made the winch mount and installed the winch. Still working on the rear bumper. I'll post some pics soon. I like the black too. When I bought it there was a black top on it, but I wanted a contrast to the black, so I swapped it for the spice color. A friend had an orange YJ and I convinced him that a black top would look better on his.

TroyD 04-16-2010 06:00 PM

great job, both of ya....Broke fish and Mcgyver.

Fish, is like to see the stinger when you get done. no matter if its pipe or tube. lol.

mcgyver1467 05-07-2010 09:24 PM

Heres my finished bumpers, front and rear............

looks good man

Everybody else seems to be able to make cool stiff out of their bumpers, all I could do was grind off the ends :rofl:

Looks GREAT!
