| R11/E28313. From F.H.R., Copies sent to: Mr. Johnson, Mr. Wormald, Mr. Nadin, Re Back Axle Periods and Bevel gears wearing noisy I think that it is highly desirable that we do not use too low a gear at present and that we make our gears of as fine a pitch as possible. The fine pitches, in the long run, will be the quieter axles, even if they are not quite so quiet to begin with. Do not make any further experiments with coarser pitch for the light model of back axle. F.H.R. L W Wormald X134 | ||
