| TO - E.H.S. } FROM R. {Sir Henry Royce} Copy to - GJ " " RJ " " DA {Bernard Day - Chassis Design} " " BY RECEIVED 5 APR 1924 V627 SLIPPER FLYWHEEL. Mr. Olley says "that for the above "they find Bone grey fibre the best material". I think if we use a thin sheet of fibre and leave enough clearance in the springs for back lash it will be quite satisfactory. I am aware that a very small clearance is used on Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) because of trouble with crankshaft, but we should get away from the need of so close adjustment as soon as possible.
