X.8410 X.3900 X.235 X.4429 One or two things seem necessary to make us happy on the above and then apparently all will be nearly in agreement for the moment, but we shall all be hoping for still better results later. (1) We must have well lubricated springs free from excessive internal friction, (nip etc.) This should be tested on every spring - (I am inclined to believe OY's improvements are partly due to fitting springs with less friction). (2) The springs must be correctly selected for the weight of the body and to our intended standards, 12½%. (3) We must at once fit shock dampers which will not cause harsh or excessive damping friction; immediately these can be RR. kxx hydraulic at front, and Lovejoy at back, and as soon as convenient RR. all round. A car with a good body should be so fitted and submitted to Sales and Messrs. Fuller and Nadin who will judge on behalf of the American Co. This is written with the feeling that Hs{Lord Ernest Hives - Chair}' convincing report of 16.4.26 is correct. It agrees with my views that it is not our standard spring rating which is wrong, but where it is not nerves it is something outside the intended rating of the springs - (unsuitable to the loads is so frequently a fault), internal friction or harsh shock dampers, or long chassis with light bodies. contd :- | ||
