| X. 7340 DA.{Bernard Day - Chassis Design} from R.{Sir Henry Royce} R8/M5.3.28. c. to BJ. BY.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} 'SS{S. Smith}' PROPELLER SHAFT. N.sch.2547 I prefer the pins going right across for fixing the tubular shaft to its ends. Avoid oil pumping by passages or holes to return oil or air past sliding serrations. I think we should keep to the square hole with rounded corners, like the original - as N.sch.2547, not N.sch.2550. R.{Sir Henry Royce} | ||
