| (2) cooling - one thinks for stiffness it should be reeded - simple pressing from thick sheet turned all over, or at least have outer flange. (10) To make a suitable supporting pin one might use ferrule construction, thus - Shallow serrations Sheet steel plate spanning both kept on by rivet. One thinks this scheme seems light and simple, allowing ample thickness or stiffness in the drum. R.{Sir Henry Royce} (Stamp: RECEIVED 19 FEB 1938) 2 | ||
