Cycle Repairing and Adjusting
With a Chapter on building a Bicycle from a Set of Parts

CYCLE REPAIRING 150 strands will fly open. Draw ont the wire and cut the spiral, then grease and push it through again. Heat the nipple (not the wire) and push it on the wire at the same distance from the end as the piece cut of! the spiral. Then run solder round to keep the strands from opening and cut of! with a sharp chisel £■ in. from the nipple. Spread out the strands and run the solder through, leaving a round head on the nipple as it was before. Screw the blocks into the shoe so that they fit the edges of the rim and miss the spokes. Fix the lever clip on the handle-bar, and bridge and spring clips on the stays. Clip the nipple in the shoe, raise the bridge until the blocks touch the rim, and pull down the spring clips until the blocks miss the rim. Fit the band clips round the spiral, and screw up all parts tight. If there is not sufficient power, raise the bridge.
