bending CDS tubing
spy - 12/5/03 at 10:20 AM

Hello guys!

I've been looking for someone who can bend the 50mm CDS tubing to make the rollbar on my car (I need a specific width/design so I can't buy a pre made one).

I've phoned a few rollbar companies up but their prices seem very steep (cheapest was £180+VAT+postage) . I've tried a couple of tube bending specialist in my area but they're either unreliable (ie never phone back with details I've requested and generally ignorant) or they only want to do mass production runs

Any suggestions?

Thanks

You could hire a hydraulic pipe bender...

I did my roll bar with one of these - cost me around £20 - £25 for a day.

Just take care to use the correct-sized formers when you do it (they're usually labelled for the standard-sized tubes' inside diameter. )

...and try it out on an offcut first, until you get the hang of the way it works!

Me and a friend had a couple done at a firm at Darley Dale near Matlock. I had to wait till they set the machine to do 50mm, they make custom chassis for 4x4s but they did us 3 roll bars for £30 each in 3mm wall 50mm CDS with a piece for a crossbar. These were to fit the standard book chassis and were done with a 7" radius bend so they didn't kink on the corners. If you are in the right area you can find someone to do most of the stuff you want at the right price eventually.

yours, Pete.

where abouts are you in the country maybe some one could lend you one .i have a pipe bender {industrial hydrolic one,not the old micky mouse machine mart type}im in teesside

Hayzee, I'm in Blackburn, Lancs (a bit far from you). Thanks for the offer anyway.

I've considered using a pipe bender but have heard it's difficult to bend 50mm OD/ 2.5mm wall thickness CDS tubing without creasing it. Is this true, or is there just a technique to it?

That would depend on the bend radius and the method being employed to bend the tube - tighter radi are harder to do without creasing.

Take a look at www.saage.com, a german stairs manufactor. They bend my roll-barr and it's PERFECT!!!!!! and cheap. It's made of 50mm brushed stainless. It really looks the part!

I had custom cages in Northants make mine for me they charged £140 quid for all the material and the bends for a complete racing roll cage ie two hoops, diagonals, braces the front hoop with multiple bends. I think that included delivery as well

Kind regards,

Hi Rob,

Absolutely love your ali/(stainless?) panelling!
Is it all done with one sheet? Or just neatly joined?

Cheers,

James

Well, James, that are 3 parts joined together at the arches. It was a pain in the ass!!! It costed me 3 days to bend and hammer the alloy around the rear end!

I certainly looks worth it, hope mine looks as good when I get to that stage
