Cheers Andy

I must admit that idea had crossed my mind

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
