I've been talking about doing it for a while, now it's time. I'll keep a updated list of the parts that I used. I did the Rear bumper first and then went to the front. So if you're interested in the front bumper skip to page 2.

Parts List:
4x6 steel rectangular tubing 6'
2 - 1x2 solid steel bars 11"
extra 3/16 steel plate
Ruff Stuff DIY Custom Bumper Fabrication Package
2x2 steel rectangular tubing 4'

I decided to use the mounts from the old bumper. I cut them off and welded steel bars on. These are going to be my main supports and go all the way through the bumper so I can attach D-rings on them on the other side.

First test fit looks good

I then cut triangles out from either side and bent the bottom up. I then welded them together. Note: the bumper is upside down in the pic.

Drilled some holes and welded in the spindle for the spare tire swing arm.

love the bumper man! its really similar to what i want to do. i have a few noob-ish questions if you dont mind. i will admit, i dont even have a welder yet and have limited fab skills but i want to learn.

first, how did you cut the holes for the shackles and receiver hitch? plasma cutter? angle grinder? jig saw? i dont have a plasma cutter but it looks like it would be pretty difficult to do without one.

second, what kind of welder were you using to burn in the shackles? thats awful thick metal. i dont think i've ever seen a non-industrial machine rated for 1" metal.

third, did you weld the spindle to the top and bottom of the bumper? if so, how did you weld it to the bottom? the bottom of the bumper is at an angle so it seems like that would be hard to cut/fit/weld.

thanks for taking time to answer the questions, and i cant wait to see the rest of the bumper!

I cut all of the square holes with my angel grinder. I first drilled hole in all of the corners and then cut out the edges.

I'm using a Hobart 230v welder with. 035 solid wire and 100% CO2 gas. It's rated up to 5/16 thick Steel. The Steel I'm welding to the 1" thick piece is 3/16 so that should be fine.

Yes I did weld the spindle to the top and bottom. It was difficult to cut the bottom. But what I did was drill both top and bottom holes first. Put the spindle in place where I wanted it. And then traced the bottom of the spindle where I would need to cut it. I then cut it with my angle grinder.

If you have any more questions or even advice feel free to post it. I'm not an experienced metal worker myself. I learned to weld off YouTube. But I like to build stuff so I just go for it.
