Referring to Rm.{William Robotham - Chief Engineer}6/R.17.3.38, whilst we are equally anxious to apply American practice wherever possible, consideration must however be given to conditions operating in these Works which are so different to those which apply in American Factories. Regarding the last paragraph in your note, an investigation is being carried out as to whether it will be more economical to machine ribs from solid castings. When the result of the investigation is known a decision will be made as to which, Cast or Machined ribs, are the more economical. RHC.{R. H. Coverley - Production Engineer} | ||
