| X8430 Wer. c. Hs.{Lord Ernest Hives - Chair} BY16/H.{Arthur M. Hanbury - Head Complaints} 16.11.26. -------------------- PHANTOM STEERING. ---------------- Referring to R4/M.6.11.26. I have discussed this matter with Hs.{Lord Ernest Hives - Chair} and our decision as to the three points referred to in the last paragraph of R's memo, which he states lie between Da.{Bernard Day - Chassis Design} BY and Hs{Lord Ernest Hives - Chair}, are, respectively:- a/- The strengthened pendulum lever. No pendulum levers had actually been forged at the time we heard of this proposed change. we therefore at once modified the die and a proof has been actually produced from the modified die, so that we know that this point has been complied with. b/- In order to stabilise the steering generally, R.{Sir Henry Royce} introduced a scheme for loading up the ball joints on the cross steering tube by means of springs so that a definite friction couple was introduced into the steering system by this means. Particulars of this were supplied to you under cover of BY/Cghl/H.9.11.26. (of which we attach a further copy in case you have not same to hand), giving a list of parts replaced and additional pieces necessary. In the memo we have quoted we ask for the present production position so that we might formulate a proposal as to when this scheme could be brought in. Apparently R.{Sir Henry Royce} now considers this design an essential factor for the lightened front axle. The Standardization Sheet has been issued and is practically fully signed up for the introduction of this part. The further information you require on the subject is that the position has now changed. R.{Sir Henry Royce} is calling for the modified part as an essential factor for C.2. Series, which means that any of the old parts listed on BY/Cghl/H.9.11.26. which have been machined, would, to meet R's requirements, be definitely scrapped. c/- The third proposal is a modified springing scheme in the side steering tube. This scheme has not actually been standardized with this axle, but a similar scheme was tested out and proved for steerings prior to the present standard of .720 lead worm and nut. To utilise this scheme it would mean scrapping the springs in the side steering, but certain other parts which would have to be replaced would be suitable for use on the next Series. when a longer side steering tube would be available and the special parts which we propose to introduce on C.2. to lengthen the side steering tube, would not be necessary. /ap Contd. | ||
