15mm Inside Dia tubing ( anyone got any?)

[gingea1pom]

Andy I think I might need something a little bespoke.

My original shaft that I have cut in half is 19mm diameter, so either end of the new extension would need to that big internally with enough wall thickness say 4mm.

Then for most of the length it could be turned down to 19mm outside diameter to match the original.

Cheers Ginge.

PS I am only up early as I am of to Weymouth at some point today until Wednesday. I will be taking my dongle hope I get signal.

Ginge......

If you can supply some dimensions....length/diameter/couplings needed etc with a drawing then i,m sure Saturn could make something for you , also we,d need to take into account the prob that Ash encountered where as his upper coupling was deemed to be too close to the CP16 bulkhead.
We,d be happy to help out if we can for you.

I wonder if putting the bulkhead on the inside would be an easy fix, would give a little extra clerance. The joint is very close to the bulkhead on the sierra so I am a bit unsure why it's a problem.

This one has me a little confused myself

I understood that the Sierra's steering shaft is designed to collapse ..... One of the clamping plates on the triangular section is held in place by a shear pin & in the event of a frontal impact, this pin would shear & allow that clamp to slide up the triangular shaft !!??

The later adjustable column has a sliding triangular shaft, the whole unit is a bit bulkier though.

Tallon???

Any news?

sorry got preoccupied with repacking my exhaust. bonus is that its now well under 99db. there was naff all wadding in the blooming thing.

ok back on subject...

this is how it was before. the inspector didnt like the fact that the bearing and joint were so close together. he felt that if i had an accident then the fire wall would have to collapse before the steering rack behind it collapsed



the solution he suggested was to put the bearing behind the firewall as this would demonstrate a degree of collapsibility

here is the picture.

as you can see the bearing is now held in place by a piece of 15mm plate made nicely to shape and welded to the chassis tube all the way round (was tricky i admit)

Is that an adjustable column Ash?
