| 1381 To HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}3/MH.{M. Huckerby}23.3.39. With regard to the various points raised at the Conference yesterday afternoon (1) We cannot say at the moment which of the 8-cylinder engines will be put into 30.G.VII. If, however, you can have an exhaust manifold ready suitable for the Buick silencer, details of which you have - By/CS.2/EH.7.3.39 - we shall be able to put any of the engines into this car when the time comes. Controls to the carburetter are not yet designed, we may have to mock these up. (2) Rm.{William Robotham - Chief Engineer} does not agree to more than six all helical gear boxes, as by the time we have the last of these we shall probably want something still more advanced. (3) We are not in a position to instruct more of the B.80 conventional engines than the patterns which you are already making. (4) It is agreed that you can go ahead with two more B.80 crankshafts with large journals, and that if it helps the situation, a further four in addition to these. The noses, however, of all these crankshafts should be left unmachined until we have decided what kind of crankshaft damper will be fitted. (5) We shall probably fit one of the early B.80 engines' 4.B.50, but at the moment cannot decide which. (6) We have asked Swdl.{Len H. Swindell} to instruct B.80 engines Nos. 4 and 5. (7) The radiator design for 4.B.50 should be finished in a week from now. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
