Rear Bumper Project

Wednesday a friend and i decided to make a rear bumper for my tj. we headed down to the metal yard to check out the scrap pile and got enough materials for two bumpers. we decided to make two and sell the second one or something. i'll try to get pics of the bumper as soon as i can.

heres a list of materials:
2"x4"x1/4" wall rectangular stock 55" long (can sub thinner material if you like but I like it beefy!)
approx 7" length of 2 1/2"x2 1/2"x1/4" wall stock for receiver (can sub a store bought receiver tube.. Northern has one for like $10)
approx 7" of 2 1/2"x1/4" thick flat stock for chain plate
approx 6" length of 3"x1/4" wall square stock (for mounting legs and receiver lip)
approx 18" of 3"x3/8" thick flat stock cut in half for the bumper mounting flanges
approx 18" of 2"x1/4" thick flat stock for bumper end caps
approx one foot of 2"x3/4" thick flat stock for clevis mounts
...and a bit of expanded metal to make a logo (we are dorks...but my friend has other stuff he can use the logo for.)


PS - we followed BESRK's write up minus the swingout tire carrier. THANKS BESRK!!! and....we're both in high school

I did mine this way for several reasons:
one i prefer the look of it out a bit, two i plan on adding a tire carrier later, three i needed practice welding and i wanted to practice on something out of the way

I do mine like that for a couple reasons. One, I do quite a few bumpers. It's much easier to generically drill 4 predetermined holes in a plate than to drill and sleeve a bumper blank... and I would sleeve to prevent crushing of the bumper body. I will cut/drill an entire length of flat steel (3"x1/2" thick), toss all the pieces into a vat of acid for 24hrs, and then rinse/dry/stack them on the shelf for future use or sale. Then, when I actually make the bumper, I just drop the plates onto my jig (the actaul rear frame portion of a CJ, YJ/TJ) and set the bumper on it for tacking. Tack up, remove and weld a good fitting bumper.. quickly. And yes.. it does help when doing a tire carrier. Keeps the carrier off the tailgate.
