The lower tubes are 3/16" and the upper part (that holds the tire) is 11ga.
cool. Mark was sayin a 220V Mig with gas would be a minimum requirement for this kit. did you experience any problems with penetration (lol) or proper heat?
None whatsoever. The Millermatic 250 (it's an older model) is a 220v welder and did just fine. You just have to experiment a little to get the Voltage/Wire Speed right for the 1/4" plate.
You just have to make sure that you only weld 2-3" at a time and move around so you keep the warping down.

I did my whole bumper, and two sets of sliders with a Millermatic 140 (110v) and everything has held together fine. I just did two or three passes for each weld. Penetration was not a problem.

Desperation is the mother of invention.
lol. Use what ya got I guess. The thing is rated for 3/8", so I wasn't too far off. It helps that it's a good quality welder and I had my father-in-law (who is a certified welder of some sort) come over and help make sure my junk was burned together correctly.

Yah and it's not like it's a motor mount or crossmember or anything that could seriously wreck you if one of the welds failed.
^ yeah.. unless you're towing a huge load and your self-welded hitch lets loose..

True. Heh "huge load"

Not gonna happen. Not sure if you can see just how many places that thing is welded and the gussets I installed, but it's impossible for it to let go unless something rips all 12 grade 8 bolts out of the frame, in which case I have bigger things to worry about than a trailer disconnecting.

Nice job on both bumpers guys. I hope these kits are still around when I need them

After a bumper sabbatical, I'm back to it! Started on the swingouts tonight. I'll eventually have a tire carrier on the DS and a jerry can holder on the PS.
Here's some pics of tonights progress.

That looks really great, I've been following along here for awhile. What is that thing welded to the center above the receiver?

Is the latch mechanism (last pic in the first post of this thread).

Thanks, I did something like that on the bumper I made for my FJ40. I guess you can answer my next question, have you ever made design allowances for a planetary style winch to go in the middle of the rear bumper? I really like this bumper, looks fantastic and very well thought out. J

That would be super easy to do. I would build a custom rear cross member to replace the factory (most likely rotten) cross member. It would bolt to the same spots as the rear bumper mounting brackets. Then attach the witch to that custom cross member. Give me some design time and I could come up with something. PM if interested.

It's been a few days since I posted. I've only been able to get a few hours into the bumper due to work, but I did get one side all welded up! On to the jerry can holder, then lots of grinding....Pardon the goober welds. If anybody feels I need to add some strength, feel free to pipe up! My main idea was to keep the tire tight to the truck and at a bit of an angle while still being able to see out the rear window and see the tailight from behind.
Whattcha think? it's my first, so it's certainly not perfect, but I like the placement.
