STEERING. Regarding the strength of the steering levers carrying the cross steering tube, the report originating from Hy.{Tom Haldenby - Plant Engineer} and confirmed by Hs.{Lord Ernest Hives - Chair} seems to be an error. I could not understand how the improved ones could be weak without other parts connected with the cross steering becoming weak also. My examination convinced me that Hy.{Tom Haldenby - Plant Engineer} had been mistaken by the natural lean of the pivots giving an apparent bend to the levers. If this is so more harm than good would come by making the levers heavier. There is however a very quick bend in the lever which has been introduced by Derby; this certainly should be made slower i.e. of greater radius. We had already suggested some slight additions to the section of the lever carrying the longitudinal tube; these are just safety suggestions which certainly ought not to do any harm: the appearance looks very light. We have on 4-Goshawk-ll allowed more clearance in the set-up spring buffers at the bottom of the pendulum lever. These buffers had very tightly set-up springs, and only .062" of movement each. We have reduced the set-up on the spring and allowed .125" movement each way, also these set-up nuts are fastened with split pins. I think one buffer might have double nuts contd:- | ||
