| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to CJ. EY. X.5300 R2/M25. 8. 25. 20 HP. SLIPPER FLYWHEEL. FAILURE IN FRANCE. Regarding the broken bolt on the 20 HP., this was probably caused through difference of friction, or seizing between the two halves of the stiffer wheel. We want this to be impossible by dowelling the two halves, and increasing the clearance in the pressure bolts. See drawing sent by E.{Mr Elliott - Chief Engineer} yesterday. R.{Sir Henry Royce} | ||
