E. 67 motor is used as standard, and besides doing allits own armature work, the company builds all its own com-mutators. Hillings & Spencer drop-forged commutator bars areemployed, with Chicago Mica Companys mica bars as seg-ments. These bars are assembled in a three-part clamp, asshown in Fig. 5, and faced and slotted in a lathe, as shown inFig. 4. The commutator is held in place while being turnedand banded mi the outside by a core, which is cast in two see- as it is claimed it can lie dune more accurately than by are first taped with white braid, and then dipped in anna-lac, and the portions which fit into the armature slots are tapedwith Star friction tape.
