| R.R. 493A (40 H) (SL 42 12-7-23). J.H., D.{John DeLooze - Company Secretary} -4- Expl. No. 9940 REF: Hsl/LGMS.5.24. EXPERIMENTAL REPORT. If we have a very weak spring in the side steering tube, the car will dive to one side although the steering is being held tightly. We find that the springs instructed for the new steering joints are very much too weak. The normal set-up on the ball is 30 lbs. On the 20 HP. it is 70 to 80 lbs. On the 40/50 cars which have been running in France with the weaker buffer springs in the side steering tube, the initial load on the ball with balance springs has been 120 lbs. From our tests so far, we think that in order to compromise between - steering wobbles, springy steering, and road shocks, the initial load on the ball will have to be between 100 and 150 lbs. Further information on this to follow. Hs.{Lord Ernest Hives - Chair} | ||
