What did you do with your 4runner today?

[emelianenkov]

I though you did one before, well nice looking bumper, how much does it weight.

It's the same one haha. We just never finished it. We built it in 8 hours so the welds were unground and the inside wasn't welded. We also didn't have recovery points, so we added those too.

I'd say it weighs about 110lbs. Maybe less, maybe more. I kinda struggle to lift and align it on my own lol

 

[Brutalguyracing]

I'm still confused as to what cracked the bumper...

You no see poles

 

[Casper421]

You no see poles

Apparently you didnt either.

truth.....

 

[Nathana92]

Glad to see you aren't giving up on it.....:banana:

Nope not given up at all. I have a new to me motor with 89k that is pretty much ready to go in next weekend.

Wow do you think you could post a write up??

Take off hood, pull out motor.

 

[emelianenkov]

Welllllllll sheeeeeeiiittttt. Grinder time!

Take off hood, pull out motor.

Best write up I've ever read. Bravo, sir, bravo.

 

[zopperman]

New mod today

time for a call to shrockworks

I was confused how that boomerang looking wood thing did that to your bumper :rofl:

I put in a call to my friend in the shipping department and he is having one rerouted form a guy in the nj/pa area
But thanks

Naw thats just project crap

 

[PWGUNNY]

Look at the pics
Was parked and went to pull out

Wow, that sucks. I imagine those poles have claimed a few victims.

 

[Nathana92]

Best write up I've ever read. Bravo, sir, bravo.

Haha yeah it wasn't anything we looked at a write-up for. It was pretty challenging as far as locating all the wires to disconnect and header clearance issues. It was a tough job but it'll be worth it once it runs again!

 

[kevinpt]

Finished it up after 16 straight hours!!!!!

Primed

Blue can of duplicolor bedliner

Now to wait for it to dry and to reinstall, then drive an hour and a half back home... I need coffee!

are the recovery points welded to the face of the steel or did you cut holes and weld it in? if i was to build my own bumper i think i would cut and weld it in and add gussets on the back side, then again i tend to over do everything i make

edit: just a thought but how about adding a front mount hitch to the bumper?

 

[jsmith21]

Got these, sucks that I'll have to wait a few weeks to go home to get them installed, the wait is killing me now that I'm staring at them..

 

[ZOMBRNR]

Nothing special, but installed the Pioneer ND-TMC10 traffic tuner for my Pioneer AVIC-Z140BH.

 

[emelianenkov]

Got in behind the bumper with my grinder and cut back the fender tab that was hitting the inside of the bumper. I also added a second coat of bedliner.

Yep, we cut through the face and TIG welded them on to the 1/2" steel of the side of my winch plate, directly in front of the frame rail, so the stress is transferred linearly. The majority of the bumper was TIG welded actually, it looks prettier This whole thing was over engineered and is STURDY! But that's how I prefer it, it makes me incredibly confident with my bumper. I know it'll stand the test of time, impact, and stress from winching/recovering.

I'm going to be adding a winch when funding allows, so no hitch for me. I feel bad for Cam (the guy that made this for/with me) because we always work CRAZY long days to get everything done lol. The only hitch I'm gonna have added to my bumper is in the rear bumper when we get to building it.

You say it's over engineered? What type of engineer are you? And can you post up your stress/strain analysis and your testing process? I am curious as to the type of testing is done on these bumpers. Also would like to see the how/where frame stress transferred under flex versus the OEM bumper. If you have load information under winch load that would be beneficial too.

Not actually analyzed but it's built stronger than cbi

As a mechanical engineer by education, a naval nuclear engineer by training and a safety engineer by profession, I feel confident saying you're really excited about a bumper you fabricated in a garage that increases your approach angle and provides better protection offroad than the oem plastic one.

Not hating, just saying.... To claim anything else is, well, just your opinion as you have no actual analysis or data to support your opinion. I personally would love to see the CBI data/ analysis as they claim in marketing and advertisements there bumpers are "bombproof"... this is just comical to me... so your bumper must be "super bombproof" then by comparison... Also, I'd be cautious claiming something is stronger than a company's product without evidence... you may find yourself in court one day because of this on the wrong side of a lawsuit....

The bottom line is your bumper looks great and you did a great job and you should be really proud of that. I know I couldn't fabricate one like that, so props to you!

this comes to mind lol
