| 850. Rm{William Robotham - Chief Engineer}/FJHl/R.{Sir Henry Royce} 22nd June, 1938. The Adamant Engineering Co.,Ltd., Dallon Road, L U T O N. For the attention of Commander Maltravers. Dear Sirs, In order to simplify the manufacture of our steering cams and to reduce the chances of eccentricity between the tracks and the cones, we wish to try some cams with the bearing cones unmachined after hardening. Will you please send us three cams to your M.22517 finished in this way. We suggest that the cones should be ground to size as at present, but that this should be done before instead of after hardening. We will subject the cones to a burnishing operation when we receive them. An official order for these cams will follow. Yours faithfully, For ROLLS-ROYCE LTD. | ||
