-2- Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}8/L.25.4.30.Contd. W.W. is so small that to get what we want, the rubber has to be exceedingly soft and in consequence, is not likely to wear well. We are therefore trying springs instead of rubbers as they have more the type of rating we require, and take up less space. The lost damping we can regain on the centre support. Major Segrave's car is worse than 1-WJ because the scuttle is so terribly flabby, and while we can prevent the radiator being very noticeable, the frame movement still knocks the scuttle about. We are, however, doing the best we can with this. Since we have managed to improve 1-WJ so much we are letting Sales have it back. though We are doing the solid engine feet on 20-EX which was not as bad as 1-WJ, has enough 'jellying' to shew us the results we get. We tried playing about with the body mounting on Segrave's car but did not get any very marked results. Since the 19" wheels were bad on 25-EX we have ordered some American 20" rims to fit our wheels so that we shall have an alternative for the second left-hand car. We will see that you get all information up to May 1st. at Le CanadelHenry Royce's French residence. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} We think the radiator connection may require modification to withstand the single point radiator mounting because the relative movement between the radiator and the engine is now increased. | ||
