| To RHC.{R. H. Coverley - Production Engineer} x4094 327 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}15/KW.17.7.34. SpectreCodename for Phantom III Frame. Da.{Bernard Day - Chassis Design} has asked us to carry out further deflection tests on samples of SpectreCodename for Phantom III frame channel. We have one at the moment in which the two parts are spot welded together. Will you please prepare a second specimen in which the two parts are bolted together, the pitch of the bolts to be the same as in the first Experimental car. We wish to compare the torsional stiffness of this with the spot welded one. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
