VISIT OF RG.{Mr Rowledge} AND HS.{Lord Ernest Hives - Chair} TO WW. TUESDAY 8.1.24. X.9940 X.4247 X.4260 X.9770 The following notes were dictated during a meeting of the design committee at WW. to consider the outstanding work on EAC. chassis etc. and Mr. Royce's recent memos. Mr. Hives was also present. RE. EAC.3. CHASSIS. STEERING LOCK. It appears to be not possible to get 40° lock on the left hand side of EAC.3. chassis. This will be 38° L.H. and 35° R.H. which however compares satisfactorily with present standard car which is 41° L.H. and 33° R.H. lock. FRONT SPRINGS. WHEN fitting brakes to existing chassis we are compelled to keep the present length of front spring in front of the axle. We should otherwise have to pull the front to pieces to set up the front ends. There will be a large number of these cars to be modified away from the Works and if they can be made satisfactory without lengthening the front of the frame it is suggested that all EAC.3. chassis could be like this. We cannot fit the longer springs anchored at rear ends to chassis we are now building for delevery until these have been tested and standardised. We should be glad of Mr. Royce's remarks on this matter. The only car we can give to the customer is the present car with the present length and weight of springs until EAC.3 is tested and standardised. From the Works point of view there is no objection to extra length of spring at the back as a new rear support has to be fitted in any case and has already been arranged for. It was thought that the new front axle for front brakes together with new front springs and rear brackets should be completed and bumped and tested as soon as possible for 10,000 miles so that as many cars as possible can be handed to customers fitted with these parts. These springs will be 25% stiffer and will be used in conjunction with the thicker rubber buffers originally arranged for. It is also thought that the car for this 10,000 miles contd:- | ||
