| X50D To RHC.{R. H. Coverley - Production Engineer} from HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}/LGS.12.27. Will you please modify the 20 HP. shaft in the manner shewn on Lec. 2480. Before the modification we should like to test the shaft stiffness, and after the modification to repeat the test. This test is somewhat urgent as it affects all the new crankshafts. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
