DT/NS{Norman Scott} 102 DA.{Bernard Day - Chassis Design}10/G.4.7.38. A.F.M. BENTLEY 111 and 50. CHASSIS. Referring to HPS.{Horace Percy Smith - Experimental Factory Mgr}5/VS.{J. Vickers}9.6.38. the items in order :- (1). Ignition Distributor. (a). A Delco distributor is now standard. E.CD.515 is not now applicable, and will not be used in future, even if a RR. distributor is finally adopted. (2). Rear Axle. (a). Rear brakes to G.CD.482. This has been dealt with by detailing. (b). Rear springs - suspension bracket secured by welding, and reduce or delete the taper pins. We do not agree to welding, but think we might reduce the number of taper pins to approximately half. We are doing a scheme. (c). Extracting tackle for pinion flange piece. The elimination of the thread is a suggestion for economy. We think it might be tried. We can easily add a thread if found necessary. (d). Hand wheel for rear brake adjustment. We do not consider a hexagon is really sufficiently accessible at the rear. We are sure the convenience of the hand wheel will be appreciated. We have issued a drawing of one less bulky looking, which we think might be tried. (3). Frame and Fittings. (a). We are issuing a scheme for flash butt welding. (b). Preventing mud and stones entering the front of the frame. We agree that this is desirable, but are not sure that altering FB.3580 is the best way. We are doing a scheme. (c). Removing rear springs. Since we are prepared | ||
