Title: roll cage specifications.
Post by: xr6jeeper on October 21, 2008, 09:53:35 PM
Hi folks! i was wondering if anybody knows the size and wall thickness for offroad competition vehicles.
I make cages for drag racing etc, we use chromoly which is very expensive so i wondered if off road spec cages were the same.
Cheers
Geoff.

hmmmmmm interesting - i have a poison spyder cage and that was the best i could find at the time.....you may have found a little project for yourself here in my opinion.

I dont suppose you know the wall thickness do you? the reason i ask is because i was going to make one for my cj, based on the rock crawler rigs in the states. If i used cromoly id probarbly have to sell a kidney, but if i can use a thick wall cds it would make it easier on the wallet and i could get away with just selling the missus. :shock:

Yep! thats what i was looking for many thanks mate.
Ive fitted a couple of those bolt together cages in drift cars, but if im honest they should change the rules and make them fully welded.
Then again skidding about isnt that dangerous, is it.  :?:

You!

I.O.M has some cool toys but I don't think he's a fabricator.

P.S. I didn't open the links above but the cages I have enquired about use CDS or T45 tube in 45mm O.D.

don't have the time to fabricate - in fact don't have much time at all for anything other than work.

It might be possible, but i cant do it pronto as ive got a major chassis job on at the moment.
Let me know what kind of cage you want ie , 4 point or 6 point etc etc and i might be able to help out .

Absolutely no rush at all, I have quite specific ideas but they are only ideas. Kind of semi-internal, semi external cage and justed wanted to know someone that might be able to do it. I have to do some body reinforcements first becaue it's a unibody on a Cherokee.

cold drawn tube is best for cages but it aint cheap and not many places stock it. scafold tube is good but try bendin it :shock:

Post by: JamesH on October 24, 2008, 09:38:35 AM
The only quote I have had was about £120 per 6m length and that was through an engineering company that I have contacts in. What total length of tube would you expect to use on a Cherokee size cage with (probably) six body/frame mounting points (3 main hoops)??

Whats size tubing is that and what wall thickness, its not far off what ive been quoted.

that my friend only you can answer, tape measure basic shapes of where u want the hoops and always round up. no matter who you are, when you start making anything with tubing - it goes quick.

or if your good ole Ponyracer, it quickly goes across the street in the grass!?!?! :twisted:
Title:
Post by: JamesH on October 24, 2008, 10:57:14 AM
Measuring is the only sensible way but I'm stuck at work and needed a little distraction - thinking about making stuff and driving on the rocks keeps me going  :roll:

I'll get some picture of NAXJA later, have you got any of Ponyracer's cage.

P.S. I think the tube was something like 1.75" OD 0.120" wall CDS but it may have been a metric equivalent, 45mm OD 3mm or 3.5mm wall. It was a while ago and I was enquiring about it to build a tube bumper not a cage so this may not be the right spec for a cage.

Sorry greg! i didnt mean to piss anybody off, you guys an gals seem to know what youre doing, and where to get the best materials to do the job so i thought id bow out gracefully.
The roll cages i make take a fair while to design and build, so i couldnt really give a price without having the jeep in the workshop and discussing what the owner wants .
Theres so much to it..... 4 point... 6 point .. then theres the cage that goes through the floor and links into the chassis.
At the end of the day what it boils down to is a lot of work .
I would like to think that one of my cages would save a life. Providing the person in the vehicle had a 5 point harness on and the seat was mounted correctly theres no reason why they shouldnt be able to take a big tumble and walk away laughing.

Ive had a roll cage i made crash at 300mph and the guy walked away , what more can i say.  :-)

you aint pissin no one off mate. all is cool. it would be nice to see an external cage available for jeeps that dont cost an arm and a leg ya see. i am gona fab some stuff for mine soon and i know it will take time but its all good fun. i enjoy making stuff for the jeeps but sometimes it would be nice to see the stuff available at a fair price for those who cant make their own. get designing somethin mate cos i am sure there is a market. 8-)

Geoff we need members willing to make kit for those who can’t or don’t have time.

True there’s a few on here who could build a rig from the tyres up, but I bet there’s a few who would have trouble fitting seat covers :-? And every skill level in-between.

Having someone who can bend tube and fit it to a vehicles is actually quite a hard find! Just because some of us know what to use and have design ideas doesn't mean we can build a cage. I'd be happy to pay several hundred pounds + materials for a cage that had some of the design ideas I wanted.

The last enquiry I made was for a front 'cage' (A+B pillars, external A and internal B - like a lot of Landrovers have) and it was £1200 +VAT. I'd like to have a 'fullsize' cage for that kind of money, something that would protect me and a lot of the body of the vehicle during a typical off road roll accident (i.e. not 300 mph, just a slow tumble, 3 at worst).
