In connection with the above Unit please receive herewith one blue print of each of the following details:- Will SFT.{Mr Swift} and EB also receive one set. D.{John DeLooze - Company Secretary} 50280 Commutator Bush - S/N 206 - 1 off. D.{John DeLooze - Company Secretary} 50281 Commutator Ring - BZ/PC 214 - 1 off. D.{John DeLooze - Company Secretary} 50282 Commutator - Brown - 1 off. Bakelite. It is thought that it will greatly facilitate moulding if the Steel Bush D.50280 has a parallel bore, we have therefore shewn this and the operation of tapering the bore will have to be done after the piece is moulded, probably at the same setting up as when the solid portion of the copper is turned off. The Commutator face will be finally trued up to 2.100 diameter when in position on the Armature. BY/WER. WER FC AUG 29 1921 RECEIVED! | ||
