If I wanted to customize some plain jane but very heavy duty front and rear bumpers, how much more support would they need than the original bumpers bolt holes on the frame. Also, thoughts on wall thickness (just in general) for steel tubing.

Come on now, I need some advice from some of you engineering types. Fabricators and DIY's, maybe someone who has made a bumper for your D1. A nearby semi-retired welder might be willing to do some work for me fairly cheap but I don't want to waste a bunch of money by overlooking something. Have a design idea, just need some been there, done that, hands on expeirence advice. Be back Friday! Thanks. Tim Oh, and by the way, if the bumpers go OK, I might try some sliders next.

Tim,
my front bumper has 4 mounting points per chassis rail. I use the stock 2 on the front, the 3/4" one right beind it (sleeved it) and the last one is the steering box mount that runs "under" the chassis rail. Total distance from the 1st bolt to the last is 27cm which restricts movement.
I'm happy to say that I have had a LOT of strain placed on the bumper without it budging a mm!

as for thickness i'd go with atleast .1875" if using box, and atleast .120" if using round tubing (DOM)

FWIW: We used 8mm sheets and 50mm x 4mm tubing

Nadim would you be able to post a pic of your bumper mounting design? .. I'm crafting up some bumpers myself and would love to have a look at the backside/underside of yours..

I just made a rear for mine and its real beefy and plain but I like it. It's not a tube because I wanted it to match the sliders and front bumper a little better. Its under my profile but to answer your question I used four 1/2 x 3 1/2 grade 8 bolts and that bumper is on for keeps (way better all around that stock if you like the looks). But you can't look at it Peter. lol

Nice thanks for the pics... Burly ass! I think it looks pretty tuff...like you could probably winch the bumper right off Peters truck!! lol Definately liking the way you've mounted it..

Tim - email me and I'll send you some pics.. I'm just starting my second bumper the first one was designed to accomodate a 2" lift.. I start with cardboard templates, and all my cutting is done with hand griders, sawzaw and welded up with a mig. If your friends a welder he'll be able to handle it all its very basic fabing.. anyhow maybe we can even trade some ideas who knows!

Peter, You're probably right and it is UGLY, BUT, was it meant to be pretty, NO...simple.

For 180$ worth of metal supplies and work, 30$ worth of painting, AND 8 hours of my own labor and welding, I truely think its a piece of art :-).

Yes, it is strong, yes, it han haul, and yes, if I want to change it later on (have a new idea to take out the current lights and make it look like a Series I Landie...can you imagine that?), its 210$ that I can sell locally for 300$ :-).

Nadim: Too bad you're in lebanon -- I have $300 burning a hole in my pocket. I asked you a few months back if you'd make them and sell them, dunno if you remember or not :-)

That and some old lady hit me in the parking lot and destroyed my stock bumper. So I'm suddenly in the market for and upgraded model.

Dave,
I'm flattered...I hear shipping a 40KG hunka steel ain't that bad of a cost! :-)

Wow! Thanks for the responses all. And as for the "ho", I just did that for fun. I have seen some snack pies marketed under the "Ho-maid" or "Ho-made" name, and when I see them I always think why would anyone want to buy a pie made by a ho. Nadim, I think your bumper looks pretty cool. Fortunately, I'm not trying to build a winch bumper right now. I just want some quick, cheap protection. I had too thought of using the large hole and the two existing holes. I was thinking that would be sufficient for a while without a winch. And maybe I was thinking a little heavy, but I was thinking about using 5/16 rectangular steel tubing. I wanted something strong enough in case I had to jack on the corner. Anyway, keep the advice coming. I want to get something going so I can have my bumpers for the Uwharrie Safari 4/23-25.

Thanks again,
Tim

You know Steve, it took a few minutes and a couple of trips to your link, but I figured it out. Like I've said before, I may be slow, but I'm not stupid!

Nadim that bumper looks like something off a Mad Max film. Foreigners always do it a little different. I guess if I lived over in the middle east I would have a big ass bumper too. You never know when shit might his the fan again. Congrats on doing your own thing

Thanks guys.
Actually got inspired by some mad americans and australians alike, so i'd like to think that my bumper is "multi-cultural" :-)
Tim, if you wanna go "non-winch", I have just finished a design for my daily driver / dune basher that I'm willing to share with you or if you can wait, post some pics up over the Easter Holidays when I fab it up.
Idea is to be light, maximize airflow, strong, and somewaht of a pro-truck style. I predict it in the 15-20kg range. Same mounting style.

Anymore thoughts on rectangular steel tubing thickness for the bumper? Chris says 3/16. Too thick, too thin? Same for the bracketry?

1/4" for brackets, no less. anything over 3/16 for the actual bumper and it'll weigh it down. each 1/16" adds up weightwise when talking arb-style bumpers

Well, I guess I'll be going with channel steel. Adequate protection (I hope) for under $100. This should do till I can afford a winch and a real bumper.

Just to throw a spanner in the works here, especially for the guy in the US...
What about airbag compliance????
Or is that something one thinks about when the time comes...

Some of the after market bumpers claim to be airbag compliant, but I don't know if they have been thoroughly tested like the original bumper. Some aftermarket bumpers do not claim to be airbag compliant at all.

There are sacrifices you make when modifying a vehicle for offroad use.

The airbag sensors or what ever they are called...are located in the frame rails. The problem with aftermarket bumpers is that they ussually do not have crumple zones. The crumple zone in your stock bumper absorbs some of the impact before transfering the force to the frame and setting off the airbag.. without crumple zones the bumper can not absorb(or bend) the initial impact which could cause the airbag to go off fractions of a second early.. or possibly in less severe impact... Thats why you should turn off your airbags when wheeling esspecially with an aftermarket bumper..

Phill, so how do you turn off the air bags on a disco? I don't suppose it's as easy as a switch. And when you go to turn them back on, will the light come on?

Timothy, for the record, I think they were talking about Ho Chung not a "ho" as in a whore. Sorry, I guess this does not add much to the post, but it was bothering me.

Yes, I got the "Ho" thing from Steve Cooper's post. This was totally unintentional. The original "ho-made" was short for home made, with a slight attempt at "ho-down" humor.(and that does refer to whore) But anyway, I think I have my front bumper figured out and hope to have it by the Safari.
