Building a Roll Cage
Hi
Does anyone have any advice about building a roll cage, I need advice on everything really like tube diameter and wall thickness, how to join the cage together and how to fix it into the car.
I have been looking on tinternet and havn't found many pics or diagrams to get a good enough idea of where to start.
I dont want it to weigh to much, it needs to be quite strong, but not going to be going 200mph or rallying into trees (I hope), but also I wont be able to afford hugly expencive hightensile carbon steel or anything else fancy
Many thanks
Ed

No I wouldnt do such a thing
Its my only car that I use it for everyday duties, but Im slowly changing it into a sort of v8 powered road going rally car.
The main reason I want the roll cage is to offer me & my passenger (only 2 seats) a bit of protection should it all go wrong, because I dont realy trust its ability to suvive a crash

Have a look on http://www.robinson-race-cars.co.uk/.
They've done an Austin A35 and there's some good pictures which would give you an idea for a home-brew cage. All you'll need to do is scale it up and then you'll need some seamless tubing, a big pipe bender, a decent welder, some floor plates and various other brackets. I'd ask them for a quote and then you'll know the sort of build budget you'll have to beat.
If it was me I'd be sh1tting myself every time a wheel lifted because i know how bad my welding is!

Budget around £125 / £150 per corner though, not cheap but worth it if you do have an offsmokeonthewater wrote:Nice one thanks
Ill prob get in touch like you say.
Looks like it might cost more than I was hoping (Im not tight just skint ) but looks top stuff

Actually John is closer for you... http://www.john-sleath.com
The MSA Blue Book has a lot of information about roll cage design and construction. You may not need to comply with the Blue Book if you aren't planning to race/sprint it, but there's a wealth of information about how to make it safe, which I assume is your goal.

Give Dave a ring, @ http://www.retroford.co.uk/ He is in Corby or try Northants Motorsport, both can probably make or supply a box of bends for your requirments.

You could always start with just a simple basic roll bar, welded to two pads bolted solidly to the floor. Then fit a diagonal. Then expand on that, but you'll need a tube bender, and some tube that can be bent without distorting.smokeonthewater wrote:Nice one thanks

Retrocar magazine did an article on building a roll cage a year or two back too. Check their website, see if they have a back-issue reference section.
