You can't use aluminium. You can't used high strength 4130 cro-moly, unless you are going full international spec.

For CAMS in Australia, you need to use mild steel (or a low carbon steel specified in their manual), and the tubes have to be 1.5" diameter I think. The wall thickness is specified also.

Buy the CAMS handbook, its about $50 and has everything.

Basicaly you need a 6 point roll cage. A center hoop, bars going back toward the rear shock mounts. Front bars going down the A pillar to the floor. Side intrusion bars. For some racing the roll cage has to be within the cabin (not go threw the firewall), and often the cage can not extend rearward of the main suspension points.

Where the vertial tubes meet the floor, they have to be welded to a 2mm thick boxed fotting I think. A bolt in cage needs thick plates bolted to the floor.

Welding is done with a MIG, and often you have to strip the car and take all glass out to do it.

roll cage material has to be 'cold drawn' pipe. that is to say, the pipe has no seam on the inside. must also be of no less than 3mm wall thickness.

[mattysshop]

you don't have to MIG, you can TIG also..

Is there a reason why you cannot use Aluminium or chrome molly?

[Steve-AE86]

you can't use aluminium cos it's too weak, and brittle.

you can use chromolly, but it's WAY expensive, and only needed for international level cages

I see, I don't want to be a pain but if aluminium is weak, why is the chassis of a NSX made completely out of aluminium?

And chromolly is WAY too expensive but how expensive is it here?

[Monk]

i her dits cheaper to buy a bolt in then to make one yourself?

Well then why start?

I'm pretty sure the NSX body is aluminium as well as most of the suspension components. I think the main chassis is still a very light steel.

CAMS banned aluminium cages quite a few years ago.
I thought you'd know this if you'd rallied for 10 years as you've claimed before, it's been covered many times in CAMS newsletters and bulletins, materials specs and design are listed in the CAMS manual. http://www.ae86drivingclub.com.au/forums/emoticons/wink.gif

The biggest problem with aluminium is that it may well be ok when new but it will work and age harden becoming brittle and losing strength with age and stress.

Chrome moly is fine for any cage but probably overkill for a non load bearing cage due to cost. It is also much harder to weld and bend than low/medium carbon steel.

Cams is basically the australian arm of the FIA, and follows standard FIA rulings, which almost all major forms of motorsport across the world follow.

Again, if you had any motorsport experience at all, you would know this, as it is written in the handbook for even the very lowest level of FIA affiliated licence.

Absolute rubbish. WRC yes but not all forms of ralli.

[crazy86]

What? what is absolute rubbish??

Sure there are local forms of motorsport which do not follow FIA regulations, but you said thet there is no CAMS in Europe, CAMS = FIA which is a European based organisation, therefore there are the same regulations in Europe as used by CAMS

[.wolfwood]

hmm fight fight fight.....

Do you want to bet on that?

[crazy86]

What country did you do all your rallying in?

[Dorio86]

Mostly Germany, but also Philippines Malaysia China Spain England Sweden France Finland Italy and Cyprus.

[crazy86]

well, therse are the governing motorsport bodies in those areas

Germany DMSB
Phillipines AAP
Malaysia AAM
China FASC
Spain RFEA
England MSA
(I assume you mean GB)
Sweden SBF
France FFSA
Finland AKK-Motorsport RY
Italy ACI
Cypress(Greece?)ELPA

Now, you havnt necesarrily driven under these bodies (example, you can drive in australia without being governed by CAMS) but these are the governing bodies for Motorsport for these countries, and ALL are FIA affiliated. Many of these areas also have many other motoring clubs that are FIA affiliated, and below that level the countless local clubs that are affiliated with their national governing body.

Ban this fo0l!

[Dorio86]

CRAZY86: I have never driven a car with a aluminium cage but I do know that most of these motor sport governing bodies usually are interested in big name competitions (big $$$), some even pass a blind eye but that's a different story.
I have seen some cars with aluminium cages, I think they were spacecraft alloy aluminium but not too sure.

hmmmm i saw on toymods earlier a fool call bubbles......he went by a whole lot of other names...and this guys ranting seems very familiar.....http://www.ae86drivingclub.com.au/forums/emoticons/blink.gif
