| -4- RM{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}1/MH.{M. Huckerby}5.1.39. Lubrication. HPS{Horace Percy Smith - Experimental Factory Mgr}/WB.{Mr Brazier/Mr Bell} is doing tests on the Tecalemit pump and Clapham should keep "au fait" with this work. Shock Dampers on 9.B.V. Should be altered to standard setting when the noise tests are finished. B.50 Ride. No work at all has been done on this ride. When Whyman can spare the car shock damper settings should be investigated. Continental B.V. The idea is to fit 14.B.V. with Gordon Armstrong rear dampers, to save 8 lbs. of weight. Clapham should contact with Roy{Sir Henry Royce}/Les.{Ivan A. Leslie} and order a pair of Gordon Armstrong dampers with bellows control. Nothing must be done to render impossible the fitting of standard rear dampers (i.e. petrol tank mods.) Draper is designing the sheet metal shock damper fixing and Clapham should contact with him to make sure the damper lugs suit the fixing. Draper is going to design a rear damper similar to B.V. front (all the latest mods.) but with an aluminium case, and bellows control, the valve being similar to the front. Wraith II. 29.G.VI Ride. Clapham is trying various shock damper mods. to see if the "floating" effect can be eliminated. W.II is an impossible car to deal with. The heavy front suspension and the inadequate bracing across the front of the frame bring up harshness immediately reasonable damping is applied to the front end. Autolock dampers are probably the only way to deal with the situation adequately, but we haven't tried them yet on account of complexity. Contd. | ||
