| To Sg. {Arthur F. Sidgreaves - MD} From Hs. {Lord Ernest Hives - Chair} c.c. to Wor. {Arthur Wormald - General Works Manager} STANDARDISATION OF CHASSIS PARTS. We think you should be aware that the whole of our motor car production in the Works at the present time, i.e. Phantom III, Big Bore Bentley, and Big Bore 25, is going through without any Standardisation Sheets whatever. In fact the Standardisation procedure has entirely broken down. Our own personal view is that the risk we are taking is justified. It must be remembered however that the original purpose of the Standardisation procedure was to safeguard the products from the optimism of designers and the Experimental Dept. If, therefore, the Standardisation procedure is going to be neglected, then it should be fully realised and consideration should be given of what it is to be replaced by. {R.W. Bailey - Chief Engineer} Since the accident with Phantom III in France Rm. {William Robotham - Chief Engineer} and myself have given this matter considerable thought. It is obvious from the Quarterly Complaints that the tests in France do not give us the complete answer. On the other hand, the fact that our cars will stand up to severe punishment and hard driving with the minimum of mechanical failures we consider proves the advantage we have gained from tests in France. Recently we have sent G.W.H. around the country on long runs and the conclusion we arrived at was that although considerably more Standardisation tests can be done in England we cannot do away with the French tests. We have tabulated the various units on the cars and are getting out a standardised test procedure for each of these units. We are confident that by revising our methods we can improve on the 10,000 miles in France. The scheme we have outlined is as follows :- We have specialists for the various units on the car. They are divided up into sections, i.e. - Leslie - Suspension, shock absorbers, frames and bumper tests. Smith - Special engine problems, superchargers, and clutches. Hardy - Steering & Gearboxes. Grylls - Brakes & Special problems. Salt - Carburetter & Induction pipes. Whyman - Air silencers, Exhaust silencers, Noise insulation, and Engine mounting. | ||
