Killer bumper, great job from a former Idahoan! 
Beautiful Craftsmanship.

I could probably make just the lower portion. Shot me an email at tetoncruisers@gmail.com and we can talk.

Well, the bumper is obviously finished (resurrecting this really old thread). Tested on some rough trails and seems to be more than strong enough. I have had quite a bit of interest to have few of them made. The killer right now would be shipping, but trying to change a few things that might make it easier to ship. I can get a pretty good rate at the plasma cutter if I get more than one cut at a time. So, is there anyone out there wanting to get one of these built for them? If there is something you don't like I can make some minor changes. Shot me a PM and we can talk.
Sweet set up! Where did you get your latches? I can't find them anywhere.
Looks AWESOME bro!
Doing the plate steel is IMO the BEST way to go with that type of bumper. I made the mistake of using square stock and had to fight with it.
Do you have the plasma cutter? Im diggin those fro sure.
Great job!

I don't have a plasma cutter, but found a place local that has a CNC system. Sent my drawings and they plugged them in and away they went.

The latch is a De-Staco clamp. I don't have the part number available right now, but when I get home, I can get it for you. I think it is the 331 on reidtool, Unsupported Browser: Reid Supply Company

If I can get about 5 people interested, I think I might try it.
Hey, looks great. Did you use Solidworks? I saw that you got a weight calculation, so that's why i'm thinking SW. I've been playing around with bumper designs in SW, too. I'm trying to figure out the best way to design the parts so that I can also just send it over to the cutters and then go pick up my bumper puzzle.
How do you determine the sizing for the angled pieces on the ends? Did you have to grind angles onto them, or did you just make it work?
I'm curious because if an angled piece is cut square, it'll end up slightly bigger than it should be, which could affect how everything lines up in the end. Maybe that's only an issue on really complex plate shapes.
Just wondering the best strategy/method for determining sizes to be cut for angled plate pieces.

Not sure I understand what you mean by the angled parts. The way I did it was make my upper plate (the one with the two holes in it), then made the vertical pieces (both left right and middle). Then created a plan with points to get the general shape. Kinda hard to explain. All the pieces you see were drawn in CAD then exported to the CNC plasma cutter. Circle the parts you are questioning and I will try to explain better.

What do I need to do to get the plans for your bumper. It would save so much time than sitting with grid paper, ruler and pencil. The old way of figuring it out. That bumper is very nice.
Fourrunner,
I'm referring to the lower angled pieces going from the left and right vertical pieces, down and in towards the truck and the bottom plate of the bumper.
Looking closer at your first pics, I can see that you left an area to fill with weld where each piece meets along the top plate and vertical pieces.
I have a woodworking background. Where you can't fill a gap with wood, then grind it smooth. (ok you can if you use wood filler, and sand and paint it)
Ideally, to build a complex shape with no filler and with compound angles you need to shape the edges of some of the plates on an angle such that they join together perfectly.
I guess I need to "get" the concept of filling gaps as you weld. So, this is how I'm treating some of the angles on my SW model.
The plates are cut square, and then I'll fill with weld?
Also, what's the optimum gap that isn't too big/too little for welding and achieving max strength and weld penetration?

Bumper and truck looking good....
Damn I love that bumper.
That is the sweetest rear bumper design I've seen!

Thanks for the comments...
Had quite a few interested in the bumper. I am thinking that I will sell the bumper as a kit. This would save tons on shipping (box would be a lot smaller) and I found when I built mine and MTN.GOAT built his, there seems to be a fair amount of variation in the FJ60 frame (not suprised). This would make it difficult for me to weld them and have them fit any vehicle without some significant design changes.
