| To - BA. from R.{Sir Henry Royce} Copy to G.I. HN.{F. C. Honeyman - Retail orders} HW. CR.{Mr Cra???ster / Mr Chichester} ORIGINAL. D R1/69/2/20. 3 X.3920 RE STEERING BOX AND SHAFT - 40/50 H.P. CHASSIS. With reference to DA{Bernard Day - Chassis Design}1/CBS/2/20, I think it would be better not to call this a steering axle but the steering box and shaft. This is rather an extensive alteration for the present 40/50 H.P. cars, but if it is convenient to make such a large alteration please put the work in hand, if not, kindly suggest some less alteration that can be applied to the existing materials. For instance, it would appear quite easy to arrange the shaft between the two levers to be increased in diameter. Certainly we would have the new 20 H.P. style in the new chassis. In comparing the scheme N.244, it would appear that you are proposing to make the shaft in two pieces. I can see the advantages you expect to derive from this scheme, but I should like a continuous shaft with the left hand lever loose, drawn for comparison. In the drawing take care to shew ample end play for the ball bearing next to the pendulum lever, which is not intended to take end play. R.{Sir Henry Royce} | ||
