Rear Bumper Fabrication - DONE - PIC added

I am attempting my first real fab project; a rear bumper. I am making out of 5"x2"x3/16" stock. I plan on shackle points and 2" receiver. I think I have a good grasp on the overall design of the bumper. What is throwing me is how to mount??? If any of you have some pictures of the mounting of custom rear bumpers I would appreciate seeing them. I am basically building the bumper that Downey Off-Road offers for the Tacoma, so if any of you own this bumper I would love to hear about how it mounts up.

Thanks for the time,
Brent

Thanks for everyone's help.....

On my Stout Equipment bumper, the mounting brackets are 1/4" thick ANGLE IRON, that slides along the frame rails from the side and bottom of the rails. Unfortunately, I have no pics.

I would at least make it out of angle iron for added strength. The mounting should be stronger than the bumper itself. Otherwise, you'll have a strong, heavy bumper that will simply cave into the tailgate or fall off if rear-ended or the truck slams onto a rock during a departure angle. Better that the bumper get bent, than the mounting brackets or frame.

One of the earlier designs that Demello did on his rear bumper was to pancake 3 pieces of 3" wide 1/4" bar stock, run that through the bumper for the shackle point and bumper mount, then leave out the middle piece back where its bolts to the frame and it then just sandwiches around the frame. He used that before switching over to laser cut brackets.

You can use square tubing, angle iron, burly plates, etc. Rear bumpers are pretty easy to mount, just have the mounts squeeze the outside of the frame rails.

Burly Plate??

Thanks Mike, that picture really clears it up. Also, what the hell is a burly plate??? After seeing your picture I think I will go with 3/16 square stock or maybe even channel stock. The square stock that you used, what size is it?

Thanks,
Brent

I don't know if its a consideration, a bumper as stout as the one your descibing as your planning to fabricate, you may consider reinforcing the outer part of each side of the frame up to the front leaf spring purchases. I can think of a variety of good reasons to do this at the same time. If the bumper it going to be drug, or used to extract another vehicle, thats a fair amount of leverage against the lightest and least reinforced part of the frame. The frame is .120 square wall tubing and the area where the cross member is, is open on the inside. Anyways, a thought.

It is done......

I finshed my first bumper last night. The only welding I "farmed out" was the shackle point welds. My welder just does not have the power to weld one inch thick material. I did not want those coming apart when pulled on. All the other material was 3/16" steel. I ended up mouting to frame with channel stock. It is ready to work.....
