| X22Y To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer}10/KW.16.9.35. Cross in Bentley Frame behind Gearbox. On the above cross which you are at present making, the upper plate forming the arch for the propellor shaft is arched to clear the propellor shaft on full bump. We think that the arching of this plate may detract considerably from the stiffness of the cross. Will you please make a flat plate as an alternative to the present one, so that we can determine this point. Hs{Lord Ernest Hives - Chair}/F.J.Hardy. | ||
