Method for assembling armatures

A method for assembling an armature for use in a dynamoelectric machine with the armature including a commutator having a bore, and a core secured about a shaft intermediate a pair of opposite shaft extensions, a hardenable adhesive material and an actuator therefor. In practicing this method, the commutator bore is coated with the activator, and the commutator is located in a preselected position. The hardenable adhesive material is applied about a part of one of the opposite shaft extensions, and the one opposite shaft extension part is disposed within the bore of the commutator in its preselected position thereby to communicate the hardenable adhesive material and the activator. Only the core and shaft are rotated to arrange the core in a preselected rotated position with respect to the commutator in its preselected position, and such rotation of the core and shaft ensures the mixing of the communicated hardenable adhesive material and its activator.
