Hi yulzari I have found the book (right at the bottom of the 3rd box very dusty box
) its called
The Rolls Royce Meteor, Cromwell and other applications, historical series No35. Published by the Rolls Royce Heritage Trust. ISBN 1872922244
Theres too much for me to type out so I am going to try and scan the relevant sections.
A few facts to get you started the Ministry of Air Production transferred 2000 worn out Merlins with 2 piece blocks to Rover so Rover could strip them for the crankshafts and other parts.
The Glasgow factory sent 600 crankshafts to Rolls Royce Derby that had failed inspection because of hairline cracks these were tested for 740 hours and showed no problems so they were used in the initial RR built batch of Meteors.
Browns foundry of Derby produced cast iron wheelcases, sumps and exhaust manifolds which were of very high quality. There usual product was cast iron fire grates and cookers.
The bore size was standardised as + 20thou so that liners removed from Merlins could be reground, chromed and used as standard Meteor parts.
The Meteor ran backwards to suit the tank transmission and the camshafts used the same lobe form as an unsupercharged Kestrel engine.
Its an excellent book and I had forgotten how interesting it is I would highly reccomend getting a copy.
