Default Oval Tube

Just wondering if anyone had a couple of bits of oval tube left over for the headlight supports they would be interested in selling? Also can anyone comment on how long they need to be to meet the IVA?

Cheers

Dave

Hi David,

if you can,t get any oval tube then just use some round stuff squeezed in a vice

as for the length.....mine are 12cm from edge of the chassis tube to the center of the hole for the headlight fitment.

cheers

Hi David

More or less what I done mate

I got a small piece of 10mm flat bar. cut it to the width that i needed, Rounded the edges with a flap disk.

The end result was a rather nice dolly that I could place inside the round tube when it was partly flattened.

This prevented over flattening & distorton of the tube

I would make you a couple of pieces up but alas....I have no more of the 25mm seamless tube left

Can't remember the length either & cannot get to may chassis to measure it for you.

140-150mm seems to ring a bell though !!??

David.......

Ronnie doesn,t have any 25mm tube left cos he made my headlamp stalks

& the way Ronnie has described how to make them works a treat...... cos they look really smart on MY chassis

Thanks Ronnie, they do look the business

cheers

Slightly off track but is there a minimum size of tube ? I have 19mm, left over from the rear tub and some 22mm. I don't have any 25mm.

I wouldnt imagine for one moment it matters what size tube you use to fabricate the headlamp stalks.

Provided It has sufficient strength to do the job & has an IVA friendly radius , whatever you have kicking about should be fine

Personally, I would say that 19mm ERW round tube would prove to be a bit flimsy, the 22mm stuff should be strong enough though

Thanks for the tips guys - will have a play when I get some tube.

If you know the mass of the headlamp, then assume it sees say 4g due to bumps - you can work out the deflection for a given tube size
