| To RHC. {R. H. Coverley - Production Engineer} from Hs {Lord Ernest Hives - Chair} /Rn. {Mr Robinson} [Handwritten]: X639 Hs {Lord Ernest Hives - Chair} /Rn {Mr Robinson} 2/LG11.11.27. CRANKSHAFT TESTS. [Handwritten]: X634 [Strikethrough] [Handwritten]: X8010 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 8000lbs/sq.in.
