Taylor's steel rear bumper

Well, starts off as a "teaser" because im not finished with the bumper yet.

Hacked up my rear hitch some. Using 2 inch square tubing. 1/4 inch thick. Beef.

Ill be stick welding all of this. 8018 rods. Bumper will include rear hitch, and two clevises.

More pics to come later.

Why would you stick weld it? Just gonna create more work for you when you go to clean it up.

If a stick is all he's got then it'll be fine. As long as he's ready to do PLENTY of grinding afterwards. lol

If it's what you have, it's what you have. I would suggest MIG... Something that's not as dirty as SMAW.

Well, it will all be welded at work. Long story short, its too much of a hassle to mig weld it at work due to my supervisor and the maintenance guys.

And as for cleaning it up when finished...it depends on how good you are at stick welding.....hehehe

Oh and I have a quick question.

I posted this in another thread, but will the two stock bumper mount bolt holes be strong enough for towing and pulling other vehicles with the bumper?

Also can I use the stock bolts, or should I get some 8 hardware?

Still gonna take quite a bit of time to clean up, regardless of how good you are

Here are my templates for the hitch mount holes. These were the original mouting points on the hitch (minus the third bolt that bolted to the bottom side of the frame)

Edges all cleaned up. These will double as templates and reinforcement for the mouting.

These will be welded onto the hitch where it will mount to the frame

The question still remains as if the 2 holes on each side for mounting will be strong enough for towing and pulling?

It's not just the tensile strength of the bolt... It's also the base metal, and being that looke 3/16" or smaller, it's gonna be a hard guess.

OP - Trace those brackets out on a sheet of 1/4" steel and drill/cut the brackets out of the 1/4" - Then weld that to your bumper. If you can, use 3/4 grade 8 hardware for mounting. It'll tow enough and pull more than enough to rip the truck in half. That's how my old 89 Rangers bumper is mounted. I built it and abused it majorly.

Also, it's more of the shear strength of the bolt that comes into play I'd say. The way most rear bumpers would be mounted, the bolts wouldn't be under tension but shear loads instead.

The plates I just cut are about 1/4 (7/32 to be exact)

Also, these plates combined with the portion of the hitch that I'm welding it to will be about a half inch, so I should be good haha

And yeah I plan on running grade 8 hardware.

And I have also decided that the plated that the clevise will mount on will also be bolted to the bottom of the frame right underneath where the bumper mounts are. Yay.

hmm...Im thinking that I should have bought the clevises with the cotter pins instead of the threaded pins.

Any suggestions? Im worried that they might vibrate loose while on the road.

You could use thread locker but if you tighten them good enough they shouldnt rattle out. The biggest problem you will have is getting it lose after it rusts.

Well I might go back and trade them tomorrow anyways.

Dont wont to worry about it bouncing down the road. Would I have trouble getting the cotter pin off once it rust (or will it rust?)

I thought the pins were rust resistant or something.

I am liking the build!

About the cotter pins, I would make sure they are stainless. I got several pins all over my Gravely walk-behind mower that is 3 years old and none of them have rusted. But the gravely is only out for like 2/3 of the year anyways lol.

The only cleanup needed: Knock off a couple of spatterballs, and wire brush. TADA.

Bumper is now about halfway done.
