In addition to my memo R4/G26.4.20, I think it will be advisable that if we use a single spring behind each ball, instead of four springs, that the rating of the springs shall be much lower. I am not sure whether the existing tubes would have room enough on the straight part to permit of a spring of, say, one-third the rating being fitted. The principal reason for this is that we must not exceed the present shock of the steering gear with a given shock to the wheel. X.205. X.3465 In addition to this point I would like you to tell me if you are thoroughly satisfied with the pendulum lever near the root. I understand we are now fitting the strengthened oval section, and the "H" section is being condemned as fast as we can conveniently change them. I would like to refer you to extract from report E1/G24.10.19: PENDULUM LEVERS. "Mr. Royce considers that new type pendulum levers should be sent round to every service station, and should be changed over on cars as they come in. He does not consider it necessary to send round to customers. This should be carried on for three months, and then the position should be reviewed again. If many defective levers are found, they we must consider sending round to individual cars, but if not, the matter might be dropped. The modern cars with centre point steering, do not get such severe shocks that the old cars have had to meet. The matter seems all to have arisen since the War, as HM{Capt. W. Hallam - Head Repairs}, had no cases previous to the war. Standardise the new lever as soon as possible without delaying out-put. p | ||
