To HPS. {Horace Percy Smith - Experimental Factory Mgr} from Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} 12/AP.17.12.36. P.3. GEARBOXES There are some more modifications we should like to test on the dynamometer. They are - (1) The strengthened side shaft rear end N.Sch.4969. Could you please prepare this for 4.HS. {Lord Ernest Hives - Chair} from the scheme drawing as the alterations are very small. (2) RHC. {R. H. Coverley - Production Engineer} 's gears with soft splines. New shaft will be required. Accurate measurements of the slack should be taken before and after the test. Box 8.HS. {Lord Ernest Hives - Chair} can be used for this test. All the old bearings should be refitted except G.56227 at the rear of the 3rd. motion shaft which should be a new bearing. Neither the 3rd. and 4th or 2nd. speed sliding pieces should be altered. We do not wish to test a concertina with soft bore yet. Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} | ||
