Next for the springs. Take 4 pieces of either sheet iron or brass for the supports, 1-1/2 inches long by 1/4 inch wide. Drill a hole in either end as shown at C, Fig. 26. A should be three-eighths of an inch wide, drilled through, a pin put in and all riveted together loosely.

Now take a clock spring and cut it into shape, as at D, Fig. 26. The top piece requires to be made hot with your blow-pipe, then the ends turned over to hold the pin B. Each piece of spring must be a little shorter than the one above it, and the ends neatly tapered, all to be inclosed in the brass band F, which has a small hole drilled at F to hold the end of the pin by which the pressure is directed on to the axle boxes, as shown in Fig. 20. A hole is also to be drilled in the bed plate over the center of each axle box to allow the pin to pass through, and also a smaller one an inch and a half on each side for the support A, Fig. 26, to screw into. Now all can be fitted into position.
