| Hs{Lord Ernest Hives - Chair} M XYV20. EP{G. Eric Platford - Chief Quality Engineer}12/WH.27.11.33 re 22-Ex - Run by EP{G. Eric Platford - Chief Quality Engineer} & H.G.Clark November 22nd/25th ------------------------------------------ As discussed further with Mr Leslie this morning, I confirm my opinion of the springing of this car, as reported in EP{G. Eric Platford - Chief Quality Engineer}21/1.11.33. I am quite satisfied that this is an improvement and in its present state could be adopted on our cars to advantage. The over-riding range seems normally more than you require for speeds up to 50 m.p.h. I quite appreciate, however, that this is advisable in order that the customer may appreciate its virtues. In order to obtain the best results from the damping as it is at present one has to continually use this control and for low speeds to run at minimum setting and gradually increase to maximum for maximum speeds. It rather confirms the fact that more automatic range is required - in fact the damping should go up fairly slowly up to, say, 50 m.p.h., and then start increasing rapidly. As discussed with you, the question of swaying is a fault with this car, and in spite of its size, bulk and high centre of gravity is still a type of car which is often bought by our customers. Some action therefore should be considered as to how the swaying can be dealt with without sacrificing the normal riding qualities of the car. EP.{G. Eric Platford - Chief Quality Engineer} | ||
