Bend the wires so that they will fit closely to the paper core and bind them tightly into position with silk thread.
Two Bearings are required to support the armature. They are cut out of sheet iron or brass and are shown in detail in Figure 12. Extra care should be exercised in making the bearings to insure their accuracy so that the armature will be in the proper position when the motor is assembled and run freely.
Two small washers or wire rings, to serve as collars and keep the armature in the center of the field, should be soldered to the shaft as shown in Figure 22.
The Base is a square block of wood, two and one-half inches wide, two and one-half inches long and three-eighths of an inch thick.
The completed Manchester motor is shown in Figure 29. The brushes are made by flattening the ends of two pieces of copper wire. Each brush is fastened under a small clamp made from a strip of tin held down at each end by a small round-headed wood screw.
Be sure that the armature is exactly in the center of the field, does not scrape at any point and turns perfectly freely.
The armature and the field windings should be connected in series. The terminals of the field marked "B" in Figure 32 should be connected to the brush clamp marked "C" in Figure 29. The terminal of the field marked "C" in Figure 32 forms one terminal of the motor. The other is the brush clamp "A."
Oil the bearings of the motor, adjust the brushes and it will be ready to run.
