| AV. Bailey (2) I agree that our standard [crossed out] gear wheels shall be steel castings we ought to have a standard design & a number of good advances by adding say 10/20% on all proportions such as 10", 12", 15 3/8", 20" dia by a usual proportions width. When making up a design one of these wheels must be used, any departure [crossed out] requires sanction from higher control. Use up stock of steel arms & cast iron hubs, | ||
