| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to CH. BY.{R.W. Bailey - Chief Engineer} PN.{Mr Northey} X457 R5/M25.8.25. STEERING WOBBLES. X. 457 X. 8430 In the conversation on the telephone yesterday I asked you to test as soon as possible an axle with vertical steering pivots, as near as possible opposite the rim. If this will not 'high speed wobble', weights should be added ne-ar the centre of the hub either revolving or not revolving. R | ||
