Outer Limits 4x4 Board

What would be the mimimun OD and thickness pipe you would use on a roll bar?

The pic is the kinda setup i'm going to make... black bit being the tray....

I have a sh*tload of 25mm ID that is 5mm thick, but i'm a bit worried about the strength....

ask cheezy 9761 8111

My bars were made by cheezy and are 50mm OD 3.2mm Dom tube.

hmm i would ask cheezy but i'm pretty sure he wont be at work still!!

I am asking tonight because if some1 reckons it will be ok, i'll make the buggers tonight!

We finished making those bars at 4.30am on a Friday morning, I wouldn`t be surprised if he was still their

which comp was it for guts?

No luck, if he is there he aint answering!

I just found a 3.2m length of 50mm OD 5mm thick... only one tho.... Might have to settle for that... Definately beating otis' budget still , the spray job and the tray have only cost bout 400 bucks together so far... 200 for paint and about 170 for checkerplate and a bit on other bits n pieces...

most rollcages for cams approval are 32mm od with a 3mm wall thickness. if it isnt for racing and doesnt need govering body eg cams approval then it should be fine to use

HMMMMM, it's touch and go with it. Being 5mm thick it should be ok, you could always make it then go for a test, really the ID is a bit small, but it should be strong enough.

got it all mapped out on the ground... just about to start bending... who's going to make the decision for me??

50mm OD 5mm thick 1 bar up front

or

25mm ID 5mm thick 2 bars up front


My ex handbrake always said because i'm a libran i am a bad decision maker.... Made one right one tho... (read: EX )

5MM is heaps,its all you will need,PM MY45 he just rolled a few times with small OD and ID it saved him but it was in a mess.
And also are you useing seamless tube?

yeah dump the woman and work on the car is the best way to recover

first of if it a big vehicle i would definatley go with the 50mm pipe.
I made a full cage for my zook and i used 50mm pipe for the main hoop and rear supports and 32mm for the front half..

Just my 2cents worth...

Most of the comp rules allow 1 3/4 pipe and the DOM tube has a wall of only 2.3mm so I think what you are using will be fine.

Sorry my last post probably didn't read well, being too bloody sarcastic for my own good

The tube will be fine!!!!!!! 5mm wall will be more than strong enough for the job, but as has been said if its a big 4x4 you may consider a bigger OD tube but not really needed.

"N*A*M" yeah dump the woman and work on the car is the best way to recover

yeah... the car doesn't crack the shits half as much!


Anyway... ended up going with the 50mm. rather safe than sorry, even if i only use it once, i want it to work!

Come up alright for an amatuer.... almost straight will fix it up tomorrow night, cant be bothered getting the lights out tonight.

Thanks for the help guys

When you said that you wanted Bar work... i thought you wanted to DO some work!!
"I'll have a Stella thanks"

five cougars thanks

cross brace your main hoop, and try not to bend those rear stays.

Bending the rear stays will make it weaker I'm guessing?

Only thing is, I dont think my new 90L esky would fit under straight ones... And remember i am a lux driver so I dont do no trip without my esky

Where's my Stella? I ordered it ages ago!!!!
