| To HM.{Capt. W. Hallam - Head Repairs} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X2430 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}5/LG30.9.26. .940 STEERING. X2430 With reference to Hml1/W29.9.26. In connection with the trouble experienced by Paris after fitting the .940 steering. We do not agree that the steering shocks with the .940 worm can be as bad as those with the 1125 worm, provided that both steerings are fitted correctly. We have several reports shewing that the .720" worm is considered an improvement. It is quite illogical to say that the .720 is an improvement, and that the .940 is worse for steering shocks. From our experience we know that the characteristics of the steering can be materially altered by a small amount of friction. We suggest that an examination is again made on the steering of this car. Possibly if a figure was given for the amount of free movement on the steering wheel rim when the worm and nut are dry, it would be useful. We consider that Ps's report on high speed wobbles is not very convincing. We do not agree that the customer is likely to be satisfied if a reversion is made to the 1125 steering.
