| To By, from R.{Sir Henry Royce} Copy to Wor.{Arthur Wormald - General Works Manager} Copy to Jt C O P Y. R3/P 10.12.13. COPY. It is of the utmost importance that we save a considerable amount of weight in our rear axle, and I should be glad if you will go over the drawing with the model pieces before you, and find out how much and where the weight can be saved. Special attention should be given to the box holding the differential and differential wheels, and in fact everything which will not reduce the ultimate strength of the weakest part. Some little time ago we proposed that the driving shaft should be hollow throughout the entire length. This would be metal well saved. As soon as you get time, please make out an account of the present weight and the possible weight when reduced. This applies right through the brakes and the hubs and the smallest details, and also to the parts belonging to the smaller model of axle known as the light back axle. R.{Sir Henry Royce} Also will you tabulate the relative weight unsprung on the Daimler, Delaunay, Lanchester and any other cars you can get the actual weightof. It is thought that our axle is relatively heavier. It may be, but I hope not. X137 | ||
