Guy Martins Spitfire
Watched this last night and thought it was very entertaining ! The bit where they mock up a dog fight with a 109 is fantastic ! Did you have anything to do with that resto Billy?
If anybody missed it and wants to see it I reckon you will get it on catch up

Re: Guy Martins Spitfire
Same company , but not one of my projects, That was a for a private customer, I look after the BBMF aircraft. Currently finishing off a Spitfire MkVb.
That dog-fight lasted about 12 minutes, he was a bit green at the end of it!

Re: Guy Martins Spitfire
I know its naive but I never realised that they were made to such exact standards. When he holds that wing bolt in his hand for to long and it wont go through because its expanded by a few thou ! I would have hammered the bastard through good job i fix diggers not aircraft

Re: Guy Martins Spitfire
Hi Ian
The wing bolts are a Newall push fit, this is an old standard of fits (specifies the tolerance of the fit)that has since been superceded by the ISO standard of fits (specifies the tolerance for the hole and also the shaft to achieve the desired fit, as it simplifies modern production). Anyhow, for that diameter of bolt the limits for the push fit are -0.00025" to -0.00075" (IE the hole is a quarter of a thou to three quarters of a thou smaller than the hole).
We fitted our wings two weeks ago, there were new stub spars on the fuselage and new spars in the wings (which had taken 20 months to rebuild), consequently they all needed line reaming before the bolts were fitted. Thankfully it was not me doing the reaming! As its the Newall standard we are working to, once the holes are reamed, they are measured and then the bolts are finish ground to provide the required fit.
We prefer to use "knocking sticks" instead of hammers

Re: Guy Martins Spitfire
All sounds very complicated mate. It would explain why the standard of work on the race car I produce may be described as agricultural when compared to yours

Re: Guy Martins Spitfire
Very cool mate. That must be one hell of a job flying these beasties everyday. I to was fortunate to be invited to Billys playground with Ryan.Whilst there he showed me the carcass of a Hawker Hurricane that was being restored. When we were racing at Donington this year the same (now restored Hurricane) flew over the top of us side by side with a Spitfire.
