Roll cage material

Right so CDS is £18+VAT per metre from a place over in leeds. I need at least 15 metres of the stuff. £324 for tube! Then I\'m going to have to spend time binding and measuring all that.

For the time and money it will take, I may order one online and pay extra for less hastle as there seem to be some full cages from the states for $450.

But by the time the cage gets here it will b costing me close to £600 and I still have to weld it in myself.

I just can\'t make my mind up as to what route to take.

Offers, suggestions, and help would be much appreciated.

Depends how confident you are at bending and welding it, there will be no room for mistakes here, if you get a bend wrong, that\'s however many meters X £18 down the drain.

My personal choice if you are a bit wary of DIY bending would be to save up a little extra and buy one pre-bent.

That\'s what I\'m worried about. The rear wheel tub to the front of the car is going to have 4 bends in it, roughly a 3 metre piece.

Its not like you can unbend the stuff either.

With a decent bender its easy enough to do the job yourself Grant but it must be a decent bender you use! Plenty of software out there that will work out pipe lengths bend radius\'s etc. If not use copper tube to make dummy pieces up as templates.

I have a bender in the shed. I was thinking of doing it in metal conduit first as I use this at work for installing cables.

A normal crush type bender Grant forget about it you will kink the tube.

[rx7boy]

you can use a standard crush bender, however you must fill the tube/pipe with sand and seal using gaffa tape. this way the pipe retains its shape and doesnt kink, its a pita though

[Skifledanabit]

So, I\'m guessing the general consensus is... buy a pre-made one... or get the material and pay a pro to do the bending?

You want a rotary draw bender tbh, you\'ll find even if you fill it with sand and bend it the ratio of the tube ovalling from a compression bender exceeds the 0.9 ratio allowed anyway.
 Try Proformance metals for the CDS, you want their ROPT510 (it\'s their specification for the CDS, bends a little neater than most).

As clive says, it depends what you want to do, as the drag guys have different regulations to the MSA, etc, generally, 1.75" 2.5mm wall CDS will do you fine for most stuff.

you need 3mm wall thick CDS for Drag racing in this country Grant

Yes I have been through the HKS rules twice just to check on the size. I am wanting to do a full cage in the car but I am wondering what the minimum would be required.

I have noticed that cage requirements are dictated as to how fast you go. So if I cage it for 8s I should be fine. Lmao.
