| BY.{R.W. Bailey - Chief Engineer} (struck through) FROM DA.{Bernard Day - Chassis Design} Copy to DJ. (struck through) HS.{Lord Ernest Hives - Chair} ORIGINAL SECRET. DA{Bernard Day - Chassis Design}2/M29.12.28. 'SS{S. Smith}' STEERING. X7430 Replying to BY/CGH{W Clough}3/N181228., as far as we can see from the drawing any difficulty there is arises with N. scheme 2574. We have indicated on N. scheme 2791. (herewith) how by increasing the size of the hole through the frame, and slightly shortening the pressed steel reinforcement it appears to be possible to withdraw the steering, having first removed the oil release valve. We should be glad if you would confirm this drawing by actual experiment, which appears very easy to carry out. We think the weakening of the frame by increasing the diameter of the hole is negligible. If the steering shewn on N. sch. 2569. had been used we believe that these difficulties would not have arisen. We are rather in the dark as to which steering is actually in use, and also the centre distance. It will be seen for instance on N. sch. 2574. that we call for 10.3. We believe steerings are actually fitted to 10.125. We prefer this latter dimension if it can be obtained without consequential difficulties. DA.{Bernard Day - Chassis Design} ◇ | ||
