Bailey - Chief Engineer} X4256 Hs {Lord Ernest Hives - Chair} 7/LG12.6.22. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) II - REAR AXLE SHAFTS. X4256 We have had made by an outside firm (E.N.V. Ltd) two pairs of Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) rear axle shafts, one pair in air-hardened steel and the other pair in selected C.H.N.S4 We are carrying out tests on the road wheel dynomometer running the car with unequal sizes of rear wheels. Comparative tests of these shafts with those which have worn badly are being made. The air-hardened shafts appear to be what we require. The teeth are really hard whilst the shaft has a brinell figure of 321. Hs. {Lord Ernest Hives - Chair} | ||
