Ref. Mr Royce's note on M1C/95212. Re Coronation Vibrations. TBB4/1.22412. Members of the 22.4.12. Tech. Committee With reference to the suggestion that coronation vibrations are due to the uneven turning moment of the engine, Mr Royce says :- "This seems a very slight amount but enough." With reference to the lack of alignment of the clutch coupling affecting the coronation vibrations, Mr Royce says:- "These also seem very small, but even this amount of unevenness is fatal."
