Now put the armature up in tlio stand, put on the pinion wrenchand allow the end to rest on the floor. Then put the other wrenchon the ring, and with the pipe extension and two strong men onthe end of it, you can start the nut. which is taken off entirely withthe mica insulating rings. We now have the whole front and apart of the inside of the commutator exposed. Set a gasoline torch or blow lamp, so that the flame will strikethe segments as near as possible where the leads are soldered intothem. When a few segments are hot enough to melt the solder. on them, take a small pair of narrow nose pliers ; catch one seg-ment and pull it toward the end of the shaft, leaving the end of thelead as it was before the segment was removed. Take the next seg-ment in the same way, and in this manner go around the commuta-tor until all the segments have been taken off. Take the pliers and lift up the ends of the leads, just enough toleave room for the new segments, and put on the ring of assembledsegments, being sure that the slots in the segments line up withthe leads. Put on the mica rings; then the clamping ring; then theclamping nut and casting. In tightening the nut, use as much pres-sure as was necessary to loosen it. Now take a hammer and chisel and set the leads into the seg-ments ; try for a ground, turn down the commutator, wind stringover the leads where they were soldered, and the job is complete.
