Oh sh1t. This is going to cost me...

Your too old for that sort of thing Jon
manek said: Ouch -- sorry to hear that Jon.
Could happen to any of us...
Yeah, luckily I missed the wall backing my F1 out this morning. Could happen to me any time ...
Seriously though - hard luck John. Looks like McLaren are going to be helpful now though. I'm sure new tyres will cost enough without worrying about major body repairs.

Well - if you think the damage a Mr. Bean mini caused to Rowan's F1 then . . .
Hope there isn't the projected shortage of carbon-fibre . . what with the war coming soon - all those carbon choppers needing spares!
I am very glad to see the response from our Mclaren clooeagues at Tracy Island . . maybe their attention was distracted by the Merc they are working on . . .
GOOD LUCK

Edited to say: glad Mc Laren have got thier act together big time!!
Hope its nothing too serious though, if its 10k for a little check-up and repair, how much is it for replacement panels
* Btw don't assume that the youth of today are all dis-respectful muppets - there are exceptions.

"It's not our policy to repair door panels without a full ultrasound inspection of the composite. We would estimate a turn-round of 8 weeks and a cost of around £10k, assuming the damage is only to the paint and outer layers"
Sorry for asking but what does a "full ultrasound inspection" consists of?
So what if the layers aren't sufficiently compressed together on a microscopic scale?? 
I suppose that if you get it decently fixed without this being done nobody else except you will bother wether if it's had an ultrasound inspection or not, having in mind you would be the only one to know of this "little incident" of course.
I guess it depends on the depth of the scratch...

So they are now going to mend it properly !
I think the concept is that the layers are either very well bonded or not bonded at all, bearing in mind that carbon fibre delaminates fairly easily-this is part of its energy absorbing characteristics.
Someone help me out on this please ! :limitoftechnicalknowledgeexceeded:
John,
I am sat here with my father commiserating at your misfortune .... Unlucky mate !
But ..... I do have some good news, and although this may sound a little Heath Robinson I can tell you of a test that is more accurate than the Ultrasound. (which is a pain to work with - sounds cool though)
This is coming from my father, rather than me. He is an airframes fitter and works in the Aeronautical Industry.
For testing for 'voids' in composite you conduct the 'tapping' test. All Ultrasound does is reflect back a frequency signal from the back of a composite and detects where there are voids as this reflection will not happen.
To test whether you do have any 'voids' - (delaminated composite) you will need a 2p coin, if you want to take the more expensive option a 10p does work as well.
Tap the coin along the section and you will hear whether you have any voids in the composite. It really is as simple as that.
Mc***** may want to run radiowaves through but it really isn't necessary !!!!
If you speak to any enigineer who works with composites they will confirm this as a recognised and very widely used form of checking for delamination.
I know where my father works certainly use it before mucking about with soundwaves !
Good luck John !
Cheers
Mark

You might try going to an F1 or F3000 team and asking who mends their chassis. Repeat this until you find an outside contractor and bring it to him.
The checking-for-delamination-with-a-coin test really does work. I haven't tried it with carbon fiber but it does work very well with fiberglass.

Ted ? Any danger of you closing this thread and directing people to this one
www.pistonheads.com/gassing/topic.asp?h=0&f=23&t=30699
instead ? My contact at McLaren is starting to get stroppy at the implication that I should get a third party to sort the car, when they have now offered to sort it.
I think that covers my legal position Chris
