| 18th Jan 1911 Re Coachwork. C.J. 18/1/11 [Handwritten note top left] Design of new back axle. July 1910. [Handwritten note left margin] X393 [Handwritten note bottom left] Just introduced R14/D18111 In altering the back axle I found it desirable that the angular torque rod should be abandoned. This is the part, I believe, that requires the floor of the body to be higher than seems necessary otherwise; and also in planning the new engine we could choose between having more room on the frame for the body or a shorter wheelbase, but owing to the necessityof putting the slipper flywheel on the front of the engine, we still cannot give more room than at present for the body, unless we lengthen the wheelbase. As far as I can see it is no use our making the frame any different shape to what it is. It is bent out to clear the axle and allow for the rubber buffer at present in use, but less room may be allowed for the buffer than we have previously given The longer main rear spring allows | ||
