does anyone know of a fully bolt together roll cage out on the market. I want to design my own for a project but i want to know if someone has already made one. I know there are roll cages out there witch are all welded up and just need to be bolted to the floor but i want to design one which comes in different parts and bolts together kind of like the polls of a tent.
cheers

No offence but i thought the idea of a roll cage was so it would be strong and withstand massive blows. Wouldt a bolt together cage just fall apart, no matter what size bolts yours using? I think there are some available tho, but as far as i know they're purely for looks. If you want a custom cage, spend the extra and get one made up, even get one and modify it.

Just a query, for all of you that are thinking about getting one made, or even making one yourself.. What schedule pipe is to be used? Sched/40 or shed/80, also must it be seamless?
Are there design lines that must be strictly adhered to, and if so does anyone have the specs on what they should comply to and also design features.

Thanks for that, will check it out tonight as I have limited access to the net here at work. I feel lucky enough to be able to access toymods forums, which i spend all day reading.... A good way to pass the day...

You have to buy the CAMS manual, and I doubt there are any new bolt together cages anymore, as they are now not legal in competition cars.

PS I would not have an alloy or bolt together cage in any car that I own. I have seen the difference between them and a good weld-in cage, and the strength difference is chalk and cheese.

I have been in 2 majors in rallies with bolt together roll bars by CDP Industries, one rolled twice the other barrel rolled 6 times, cages held together fine, pity the cars didn't survive but we basically walked away both times apart from harness bruising and very severely dented wallets.

Remind me not to drive with you  Good to hear that all is well though.
My dislike for bolt together cages is that the joints are not solid, and often the method of bolting into the car is not real flash.
Like the old helmet ad goae "If you have a $10 head, then buy a $10 helmet". My life is worth more, and in my RX2 Club car that i had, I spent about $1k getting a VERY good cage welded in that made me feel vey safe.

Actually I was only driving in one instance the really big omne I was the navigator, but it still all comes back to how they were made, these were all custom fitted and engineered to fit the particular car they wee fitted to, not bought off the shelf and fitted. Hence mounting points and braces were solid and correctly positioned to supplement the original strength in the shell. Agree that the only option is to buy the best that is available, hence I was using above the recommended spec Chrome Moly tube when everyone else wanted to use aluminium to save weight, the way I looked at it my head was woth more than saving 5 kilo's in weight, and as I said we both walked away without real damage.
p.s. seats and harness also need to be up to it, safety is a total package where all bits must be right and is more important than go fast bits at the end of the day.
