| To EFC. {E. Fowler Clarke - Electrical Engineer} from R. {Sir Henry Royce} -2- R14/09/11/21 Contd. of forcing the erection rings over the commutator plates. Mr. Hives informs me that there has been an attempt to force the bakelite between the plates, but surely this must be a misunderstanding, because as far as I can understand it is impossible to build a commutator up without separating the plates by sheet insulation of uniform and exact thickness.
