| To RHC.{R. H. Coverley - Production Engineer} X1020 Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}15/KW.9.12.35. LEAD BRONZE BEARINGS. We are allotting B-4 unit for the test on lead bronze bearings slightly bell-mouthed. The main object of the test of course is to see how small a clearance we can run at with these bearings. You will see from Grylls' memo. that with certain manufacturing methods they definitely state in America that they can get down to whitemetal clearances. Perhaps you will let us know whether you can use their methods. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
