| X. 8430 To BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to CJ. HS.{Lord Ernest Hives - Chair} S E C R E T. DA{Bernard Day - Chassis Design}2/M28.8.24. E.A.C.ll. STEERING COLUMN. X. 8430. Mr. Royce has recently instructed that the mixture control should be replaced on the steering column. It is intended to use a single pole switch, one side of the Klaxon being earthed, and this enables us to get a single wire down the steering column, getting over the trouble you have recently referred to. We send you N.sch. 1837., shewing the slight adaptation to the Goshawk switch to make it single pole, and shewing it mounted on the top of the existing 40/50 control gear above the steering wheel. The switch on the existing controls you have already had, but these are slight modifications shewn here. We have also looked into the question of the connections between the steering worm and its driving tube, and Mr. Royce would like to try the simpler method used on Goshawk 11. of brazing the case-hardened worm to the tube, which he believes you can do successfully. Alternatively to this, we have proposed a tube solid throughout with a case-hardened worm, and should like your remarks on the three methods now suggested, as regards manufacturing.
