I'm not. I sent the CAD drawings to a buddy of mine who is a fabricator. He's got a plasma table he will be using.

I'd be interested to know about esitimated material costs for this build as well.
Also, any chance of exporting to some other formats, like Inventor Fusion? I'm no CAD guy, but I'd love to take this idea and run with it. Some immediate ideas are to add a swing out or two (if feasible) and rear quarter protection.

Trimetric view please. I think that's the one.
You have inspired me, I'm going to brush up on my SketchUp and get to work.

I'm not sure what "trimetric" view is. Describe it and I will do my best to get you the view you want.

I can export into DXF, DWG, and quite a few others. Once I get the bumper built and installed I will go back and make sure all of my measurements on the drawings are precise and any issues are corrected. In regards to cost here's a break down so far:
The tubing was a little over $100
The hardware was about $15
The 12" trailer hitch tube was $17 http://www.harborfreight.com/18-inch-long-2-inch-standard-receiver-tube-97093.html
The plates are about $40 worth of 1/4" plate
The cost to cut out the plates is unkown. My buddy is giving me a sweet deal. Not sure what a regular shop would charge. Probably another $50.
So were looking at a total of about $230. you include tax and driving around to pick up the parts I would say $250 is a safe overall number. I should have enough tubing to also add some rear quarter protection kinda like the slee design. I didn't add that into the drawing because I knew that piece would probably have to be eye balled into place once the bumper was all mounted up.
Love your design and especially like that you are taking into account a weight savings program. Some of the bumpers offered are indeed beefy but really add so much weight to an already heavy vehicle. I would like to see more of the go light route. Looking forward to seeing your finished projects both front and rear. Maybe look into doing some sliders as well?
why have the shackle stick out so far? i hate hitting my knee on the hitch if i leave it in the shackle mounts are not removable. I figure about a 90 deg rotation is more than enough for the shackle. you could almost move it in line with the the main tube pieces.
I was planing on making a very similar bumper and debating on shackle mounts. I think I will follow your lead three 1/4 plates seems way more than needed and not much more money, why not. I would cut the center plate 3/16 smaller so the weld fills in nice with good penetration. I will probably kick the side wings up a little as I have a 1.5" body lift.
Thanks for the ideas.

Sliders are already on. I bought those and didn't build them. I regret that approach. I could have designed stronger and lighter ones for about 1/3 the cost. Oh well, lesson learned.

Thanks for the feedback. Good ideas in there. In regards to the shackle mounts sticking out; I wanted them to stick out past the tubing so I could wrap the plates/shackle mount up and around the uppder and lower tube. That way the tube is quite secure when tugging on my 12k winch. I might still be able to keep my idea but bring the mount in. I will look into that.
that makes since. some gussets on the inner corners could help with that too. when i think about tow points i think about how companies make hitches. there is not to much to them and a bet they are way over built. the stress analysis your class is doing will be great to figure out what is needed. looking forward to what you find out.
what about a receiver next to the frame so you don't have to worry about it? then you could save $ and use HREW. a quality HREW is made of 1018 and not a bad piece of tubing. most comparisons are 1010 HREW/pipe to 1020 DOM. Just a thought. I have spent a ton of time thinking about tubing and doing my own research and do not think DOM is worth it unless its a high speed role cage or suspension and in which case a 4130 Chromoly would probably be justified.

What do you mean by the "reciever next to the frame"? Are you saying to slide the reciever over (offcenter) and weld it right up against the frame mounts?
I like it! The longer I've been in to 80's the more and more I like the simple tube bumper look. Especially for the rear.
Trimetric is probably not the correct term, it has been over a decade since I did any CAD. Starting with the Iso, move the perspective down.

Here's a couple more pics. One in orthographic iso with the perspective pointed down and another from the other side in 2 point perspective with the angle higher.
Awesome! I can't wait to see pics of this on the truck.
Looks great. Subscribed.
Ya. Put a second receiver next to the frame so you do not have to worry about the forces a 12k winch will put on it
I wouldn't worry at all about winching from the receiver. You look to have your force from the winch spread out through the mounting wings and the grade 8 hardware that will be holding it to the frame. The outer wings will be more than sufficient to handle the stresses of side pulls with the material you plan on using for your build, but I personally would stick with DOM over hrew.
This is very similar to the rear bumper I had on my 1992, and after seeing this, I'm tempted to cut the one off my current 80 and borrow your design.

Have you made any progress on this rear bumper? I would love to see what it looks like if built up and installed?
Not sure where you're at but looks like the ps wing frame brace will interfere with the exhaust??
