| BY/Btnl/P1.11.19. - 4 - We propose following this up by making tests on full size aero engine cranks, Falcon, Eagle & Condor, which can be cut from scrap shafts. The capacity of the testing machine is 150 tons inches, which it is thought will be sufficient to break these. We hand the fractured test pieces to Bn{W.O. Bentley / Mr Barrington}, for examination, and to forward to R.{Sir Henry Royce} BY/Btn. | ||
