| To RHC. {R. H. Coverley - Production Engineer} X5310 Hs {Lord Ernest Hives - Chair} /Gry. {Shadwell Grylls} 6/KW.5.3.34. Synchromesh 2nd Speed Gearbox. We think it essential to have a second gearbox of this type. The one fitted to the Vulture(Experimental 6 CYL OHV LONG STROKE / Aero Engine) is very noisy and the synchromesh operates erratically. We could fit this box to 1-J-111. Will you please also put in hand a set of close ratio ground gears. We think we should also try 8º cones screw threaded in a similar manner to those shown on N.Sch.3994 for the 20/25. Hs {Lord Ernest Hives - Chair} /H.Grylls. | ||
