| COPY. R2/P.20.9.13. To Wor. {Arthur Wormald - General Works Manager} from R. {Sir Henry Royce} Re. Front Axle Pivot, for 10 HP Cars, X714. Chandler 11/9/13 WOR {Arthur Wormald - General Works Manager} /S/S/L17913. With reference to Type 2 Front Axle, section 200, Blue Print 132, it appears that the track of these No. 2 cars was 50", but it could soon be ascertained by examination of the rear axle as well as the original front axle. I do not know that there was any difference between them, except in the case of the one car which I used at Quarndon. I should think that it would be quite in order to continue the use of the tubular axle, but before making a number from the Drawing 132, I should like to see the wheel leaning outwards at the top, say 1 1/2 degrees and the steering pivot inclined from 3 to 5 degrees, so that the road contact shall be nearer to a line continued through the steering pivot. The blue print 132 I have marked with the following notes:- "Inclination of wheel. 1-2 degrees. Inclination of steering pivot 3 to 5 degrees. Add something to the centre of the pivot to make up for the inclination of the wheel, so as to keep the track constant. | ||
