| X64 Exptl. Dept. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}9/KW. 12th September,1935. C.W. Ward, Esq., Messrs. Park Ward & Co.Ltd., 473, High Road, Willesden, London, N.W.10. Dear Mr. Ward, The steel-bodied car will be at your Works on Friday morning the 13th inst. We have kept the car longer than we intended so that we could complete tests on it on our torsional rig which you saw. The results of the tests indicate that the best thing that we can do to improve the car as it stands is to fit single piece wings and running boards. We have not tested the car with solid body mounting instead of the silent bloc, but we have tried it with the scuttle bolted solidly to the dashboard. This reduces the total movement slightly but carried the frame vibrations to the passengers rather too much. We think we cannot take advantage of the body stiffness until we get more rigidity from the dashboard forward, and therefore silent bloc bushes are the best mounting for the body at present. Yours sincerely, FOR ROLLS-ROYCE LIMITED. | ||
