2nd Gen Rear HC Bumper Build (Pics)

[tweeek]

I have started fabbing a rear HC bumper for the taco... My plan was to do a swingout with a 33 (probably a 35 sometime in the future) and 2x20L Scepter MFC fuel cans. I have a Summit machined spindle coming in the mail, but I am concerned of all the weight on a single swingarm, and am considering going with duals.

Can anyone chime in who has 2 cans on their swingout??

Main body is a 4x4x1/4 hopefully have the mounts and recovery points finished today....

Obviously the sides havent been cut to legnth yet. Waiting on my spindle to come.

My plan is to bolt the recovery point to the mounting plate with a couple 5/8 grade 8 bolts. The way I have the mounting plate sitting inside the 4x4, it would be impossible to weld the recover point while inside the tube, or if I welded it first, I couldn't get the recovery point through the hole in the front of the bumper without making it quite large because of the "keylock" design. This way, I can fully weld the mounting plate, then attach the recovery point after.

Ill get the other one drilled out and hopefully get them welded in today.

I love to see DIY projects! Keep going...looks like you're off to a great start.

Havent had alot of time to work on this in the last few days, but got a few things done.

Got the recovery points drilled and welded in. I changed my desig a little and as it turned out I had plenty of room to weld them front and rear, so the 5/8 bolts were really redundant, but I had already drill pressed the holes.. no matter.

Got my main mounting plates welded in. Definitely not my best welding, but it was pretty awkward welding inside the 4x4. This is only my 2nd metalwork project really.

Spindle came in the mail... this thing is extremely beef! Just to give an idea of scale, thats a 35mm axlenut socket beside it lol. I pounded the bearing races in and got it ready to go.

Laying the swingout out

Still trying to decide whether to go single or double swingout.

I went with a duel swing out, thinking it would be too much weight on the single pivot
Three fuel cans on driver side and tire on passenger side.

Got a few more things done. Progress is slow but surely moving forward.

Did some CAD work (Cardboard Aided Design lol) Mocked up the wrap around sides and got the holes drilled for the spindles. There is gunna be alot of pieces to cut out! Lol

Still have to finish the mounting brackets before I start putting the sides together I think.

I think.

Looking good. The side wings are gonna help a bunch.

What are you using to cut the holes in the 4x4 square tubing?

 

[Fleetwood]

I would say a plasma cutter

Oops, sorry, I missed this first post.

Yes, I am using a plasma cutter I was fortunate enough to borrow. While the plasma is super handy in some aspects, its pretty rough too.

Realistically, you could do all of the adove with nothing more than an angle grinder & zipdisc, maybe a 3" cutoff for the smaller recovery tab holes. I didnt have access to a plasma when I build my front, just 1 4 1/2 grinder.

I have a CBI with a single swing, full size spare, 2- 20L scepters and fold down table, no problems. Ron

Thats awesome. Good to know! I am leaning in this direction just to keep things simpler. Does your spindle have a bracket on the top to tie back into the frame of the bumper? Also, I am gessing tire is mounted on the hinge side?

No bracket and the tire is center mounted. Ron

Got a few more things done today. Fabbed the tire carrier portion of the tiregate. Also got the spindle welded in.

Going to get some gussets on tomorrow and finish the frame mounts.

Making progress! Nice going.

After having a rear mounted spare on my FJ, I would urge you to take a look at the way Toyota chose to build that. There is a nice lip that sticks out farther than the lugs (through the hole in the center of the rim) so that you can set the wheel and tire up on that to get the lugs aligned with the holes. Made life a lot easier when hefting up a heavy wheel/tire. May not be a big deal unless you rotate your spare into your normal tire rotation like I do. I like to have all my tires wear out at the same time. That lip will also save your lug threads from getting messed up by banging your rim onto them and then dragging it across.
