| 628 To HPS. {Horace Percy Smith - Experimental Factory Mgr} from Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} c. Wym. {G. Harold Whyman - Experimental Manager} Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} 6/AP.2.2.38 WRAITH GEARBOX In view of the success of the experiment of fitting a more flexible transmission shaft on 24.G.Vl. {V. Lewis / Mr Valentine} and its stiffer subsequent failure, we should now like to try a shaft softer than standard, as this might also remove the critical period. Will you therefore, please put in hand a shaft to GW.779 but with the outside diameter increased from 1 1/4" to 1 1/2". The driving teeth on the shaft can be left soft.
