| Exptl. Dept. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}9/KW. 10th December, 1934. M.{Mr Moon / Mr Moore} Olley, Esq., c/o.{Mr Oldham} The Cadillac Motor Car Co., Detroit, Michigan, U.S.A. Dear Oy., Thank you for your various notes. With regard to pistons, Ellis already has particulars of the can form with which we grind our own pistons. In case he has lost them we send the latest figures of the Aerolite pistons which have been standardised on the Bentley. With regard to steering, we have reverted to the parallel links on the front and find that these completely eliminate road shocks, even with the Rolls-Royce worm and nut steering. Apart from road shocks the steering is not quite as nice as with the Cadillac link lengths, as it tends to over steer somewhat on corners. We think, however, that we can see a way of getting over this; we may come to some compromise between the two arrangements. The fact that the gyroscopic forces due to the tilting of the wheel do cause road shocks is confirmed by the Dubonnet suspension which we have now got fitted to a 20/25, this is also free from road shocks. We are interested in your remarks re the front roll rod. At the moment we like the roll rod at the back because it helps to keep the rear axle on the ground. Can you tell us whether the rubber in your shackles has any bearing on the freedom from axle dither in the back seats? | ||
