| To BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to CJ. HS.{Lord Ernest Hives - Chair} X9430 S E C R E T. DA{Bernard Day - Chassis Design}1/M7.2.24. E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. X.9430 We send herewith N.sch.1747 shewing roller and ball bearings applied to the rocking shaft for EAC.1.11. and 111. steering box. In the event of the steering as arranged for EAC.11. with reduced lead of worm proving satisfactory this scheme will not be required. Should the original lead of worm as for EAC.1 be preferred, and the steering still be heavy with plain bearings, the use of ball and roller bearings should be tried. It will be noted that the distance between ¢ car and centre-line steering is 10.250 with this scheme. We think the bracket shewn supporting the steering box on frame will present no manufacturing difficulties and will avoid any tendency to bind the roller bearing.
