| X8010 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} 2/LG11.11.27. X634 CRANKSHAFT TESTS. Will you please machine a second key-way on the crankshaft which we are using for our tests at present. We think this will be necessary even if the taper is made 100% fit as at the present moment the single key-way is stressed up to about 9000lbs/sq.in.
