CHASSIS DESIGN. ---------------- Phantom II - The design and detail work has been completed for the 10,000 miles test car 28-EX; the chassis itself is well advanced. Further work in hand includes the synchromesh 2nd speed gear box, the design work for which is well advanced and will shortly be issued for detailing. 20/25 HP. Chassis. ------------------ The design work covering all the modifications which are to be incorporated in the next 10,000 miles test car, details of which have been previously circulated, has been completed with the exception of:- (1) Brake leverages for direct-pedal operation to all four wheels. (2) Servo with reduced frictional losses. These two items are being dealt with at the moment. The detail work for the 10,000 miles test car is well advanced and there remains only a few items to be cleared up. 20/25 HP. Engine Single Cylinder Engine Unit. ------------------------------------------- Detail work for this section has been completed and the principal castings have been made and are on the machines. This unit will therefore be available for test in the near future. Bentley. -------- Numerous design modifications have been issued to deal with failures that occurred on the last 10,000 miles test and to improve the car generally as the result of tests and criticisms. There are as a result quite a number of features available for incorporation in the next 10,000 miles test chassis. Design work is in hand for the following additional features for this car as follows:- (1) Dropped front crossmember. (2) Improved engine undershields. (3) Modified position of battery box crossmember to give increased body accommodation. | ||
