You will note that on the Vauxhall one side of the engine is fitted with a pressed steel plate, retained in position by studs and nuts. The object of this arrangement is to save weight as the steel plate is considerably lighter than the cast iron wall which it replaces. Fords do the same sort of thing, but weld the plate on to the iron casting by means of a somewhat elaborate machine. In view of your success mating up iron and steel pressings on the drums, we wonder whether it would be possible for you to cast in a pressed steel plate on B.50. If you think there is a possibility, and would let us know how you would weld it in position, we will make a drawing to which you could work. Rm.{William Robotham - Chief Engineer} | ||
