Rear Bumper Fab Underway
After designing this thing months ago, Im finally starting to build it. I used SolidWorks to make a rough 3D model of the rear of my runner, and then I modeled a bumper to fit. Then I spent some quality time at work to make the 2D AutoCAD drawings. So, as long as my 4Runner model is perfect, everything will go together perfectly. Yea right.
Anyways, so as of now I got the 1/4" connection plates tacked onto the main tube (3"x4"x1/8" sqr tubing) and got the holes drilled. I am using the 1/2" stock towing hitch mounting plates to attach my bumper to. I used a friends shop to cut the bottom of the towing hitch plates off and got some holes punched in them. So now the next step is to get the 1/8" side plates welded on.
You'll see in the close up pic that I had to redrill my mounting holes. I realized after I punched the original holes that I wouldn't be able to bolt in that location because the 1/2" plate I was mounting to had some steel welded to the back of it there. So, I had to redrill back a couple inches. The bolts are a little cramped and one is too close to the existing hole, but it will get the job done.
I'll update with more pics as the works progresses.

I'll support the sides off the main vehicle frame. Come off perpendicular and angling up to the frame. I didn't inculde the frame in my 3D model so I haven't designed that part yet, but I'll just field measure something in after the bumper is basically done.

I'm asking cause it looks like a good stout design you might be able to market since it looks similar to some of the winch mount fronts I've seen.

More than anything this is kind of a learning project for me. I've only been welding for a couple months now. This is about my third project, and definately the biggest. It should be fun and hopefully it looks good in the end.

Well, the plan was only to buy it, do the valve job and sell it, but then I crashed my gold 4runner and never got any money out of the lady that hit me. I hate people from Evanston WY that drive in Utah without car insurance and then get thrown in jail so you can't garnish their wages in order to collect on the judgement you were awarded in small claims court. I'll probably never get my $4000 out of her. So, the blue runner has been good to me and we'll keep her until I decide I can afford something else.

OK, I've finally got all the main pieces tacked together. I still need to tack on a few final pieces, but you wouldn't even be able to see those from the pics I took, well, except for the trailer hitch and the tow lugs. I had to do a little grinding and have a quarter inch sheared off a few pieces, but overall Im very pleased with how its turning out. I do want to cut out a piece that will fill the gap that you can see in the upper corner of the bumper. Also, the very front upper edge of the sides are rubbing on a tiny spot of the body, so I need to figure out the best way to deal with that. Im thinking maybe epoxy on a piece of plastic or something so that it won't rust right there. I'll get quite a bit better departure angle with this new bumper. The bottom of this bumper sits about 3" higher than the stock bumper. Check out the new gap I have between the exhaust pipe and the bottom of the bumper. I'll have to think about relocating that later. Anyways, here are some pics:

Not sure if the body and frame flex on a second gen like they do on a third, but if you have any part of the bumper rubbing or quite close to the body now, you may want to re-think that clearance. I would want, at a minimum, an inch clearance away from the bumper and any body part. Otherwise, if you hit the bumper hard, you stand a good chance of getting some body damage. Just a thought.
