| contd -2- whereas it is only necessary for a passengers to ride a few yards on the floor to realise that without the cushion any car is absolutely impossible. We are now running a Phantom car fitted with 72" semi-elliptic springs and Hotchkiss controlled back axle. This car does, we consider, ride better than the standard car. We feel that there is considerable side translation on the overhung portion of the 40/50 HP. frame. We also think that with the front wheel brake 40/50s. one gets more road shocks on the steering, which is in effect, the same as a wobble without a period. We think these shocks can be felt thoughout the chassis. We are very interested in your arrangement for testing cushions. Could you please let us have particulars of the scheme you propose to use. Knowing Messrs. Woodheads Burford and Searight as we do, we do not put much value on their comments on R-R springing. We think that individual impressions of springing are valueless. The best guide is the average opinion of the users of the car. Our records shew that the complaints of springing on the 40/50 HP. are actually less since we fitted F.W.B. than they were previously. In spite of that we still get approximately 20 complaints of the 40/50 HP. springing against one complaint on the 20 HP. This is rather surprising because with the lighter and shorter wheelbase car one would imagine the springing to be worse. Hs.{Lord Ernest Hives - Chair} | ||
