In view of the difficulty experienced by ROY{Sir Henry Royce}/Les.{Ivan A. Leslie} in finding anyone who would be able to produce the fan pulley in the form shown on PD.260, we have altered the pulley making it in two parts welded together, one part being a pressing and the other a spinning. The thickness of the material to remain at 16.SWG. for the time being. Will you please detail and instruct for the experimental B.80 engines. DA.{Bernard Day - Chassis Design} | ||
