With regard to the proposal in Rm.{William Robotham - Chief Engineer}1/R.25.7.37. to use .062 thick shells in place of the present ones of .125, there is no objection to this from the Production point of view apart from the increased distortion which may arise and complicate machining. In order to confirm that machining cost and scrap are not likely to arise unduly, we should like the opportunity of producing some experimental parts on production machines so that possible manufacturing troubles may be investigated before the pieces are Standardised. The smaller bore in the connecting rod itself will be of assistance in preventing the slight distortion which at present occurs after service. RHC{R. H. Coverley - Production Engineer}/S.Bannister.
