| To Hs. {Lord Ernest Hives - Chair} & BY. {R.W. Bailey - Chief Engineer} from R. {Sir Henry Royce} c.c. to BJ. Wor. {Arthur Wormald - General Works Manager} OY. c.c. to PN. {Mr Northey} CWB. EP. {G. Eric Platford - Chief Quality Engineer} X4565 R2/M3.9.26. STEERING, AND LOW PRESSURE TYRES. X. 8430 X. 4565 X. 5430 I understand it is now agreed by Sales and the RR. engineers that larger size tyres can be used, and recommended on all RR. cars now being produced, and it is necessary that the following points are included :- (1) Well damped axles by our hydraulic shock dampers on the front axle. (2) Well damped steering pivots by the extra washers on the pivot pin thrust. (3) Lower geared steering, either .720 in latest box, or .850" in XXXX original Phantom box, and .750 in original Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) box. Any complaints of steering should be met by putting in one of these slower speed worms and nut. I understand there are many complaints of Phantom and Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) steering, and I recommend that we deal with them promptly and generously. I also understand there are complaints of insufficient rigidity of steering column. These have been met by the use of the extra stay from dash to column (triangular), which should be made and stocked for back numbers of Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine))s or Phantoms. Hs. {Lord Ernest Hives - Chair} makes some error regarding 20 HP. Some public, or press demonstration should be arranged. R. {Sir Henry Royce} | ||
