Roll Cages


Recommended Posts

'Nige & Jon', great job - how did you bend the plates where the cage mounts to the body (like the outer curved edge of the roof, for example) - just heat / brute force or what? Looks like a great fit.

Series3_mad - can you not just measure your truck?

Cheers, Al.

I'm a bit sketchy

That why I was asking

I have been told that its coming in but not when I don't fancy turning up for a meeting be being told I can't race due to my cage is out of date. I was watching the WRC on ITV and you can see on the WRC scuby that there is a extra cage brace like a quater light in the cage next to the driver and co-driver. I assum this is the new brace. Robbo did not tel us anything about it but I will have a look at the Auto Sport Show in jan to see whats new. My main worry is that the cage will have to be hacked about to weld in the new section and it will look a mess. I will be well Mildly miffed if it meens a new cage for both cars.

The roll cage Regs are very rarely applied retrospectively Jules. The cages you see on the WRC cars are totally different from your "basic" FIA approved cage, having additional bars for rigidity well beyond what the FIA Regulations require.

If you bought your cage "off the shelf", contact the supplier/manufacturer and ask for a copy of the "Roll Cage Certificate" or "ROPS" Certificate. You can download the technical cage specs from the FIA site (once you find them).

You wil need to get a Competition Car Log-book from an MSA Scrutineer (Nat B or above) if you intend to rally in UK. The Freelanders should be fine as they still use the original monocoque and you will know what the rest of the safety kit is. BTW remember you'll need in date FIA belts from 1 Jan 06. John Cockburn got his RRC log-boked for Mull last year with few problems (by me), so I don't expect too much hassle with your Freelanders. Robbo should be able to sort you out. Drp me a PM if you wnat any more info.

Roof plates.

These are both inside and out, and are 6mm platework.

Basically Jon Made a cardboard shape of the profile of the roof, and we jointly then made up a HUGE clamp which was to go inside and be joined to the cage.

This was then clamped in the vice, and some predrilled 6mm plates bolted to it on just one side..., heated red hot with my Oxy acet and then bent, ......and 'presuaded' to follow the profile....

They did make an amazingly nice shape, ..............

the trick was to take time, have very very red hot, then lay a big piece of solid rod ......(50mm rod !) ......over the metal bolted to the mandrel clamped tightly in the vice...........................................

and then hit the living daylights out of it, ................

just a few blows "Rolling" the plate over the former...

after a few blows the steel was reheated and red hot and repeated....

These then gave us the plates for the rooof shapes.....hope this makes sense

Yeah great cheers, makes sense - it worked really well. That pic looking along the side of the roof with lots of sky in it - the profile looks perfect. Nice work.

This post is for White 90. The attached photos should be all the ones required. I'm pretty sure they all came from the thread under discussion. I tried to attach them to the original thread but it wouldn't let me, nor would it let me start a new post in that section, so I've posted them here!
