i8 CYCLE REPAIRING carefully how the spokes are crossed in the wheel before taking it to pieces. A very common job is to fit a new two-speed or three-speed or coaster hub in place of an old plain hub. In this case it generally happens that the flanges of the new hub are considerably larger in diameter than the flanges on the old one. This will, of course, necessitate the spokes being so much shorter than before, and the spokes will thus require cutting and re-screwing. The best plan will be to measure the diameter of the old and new hub flanges at the spoke holes, and cut nine spokes shorter by half what this difference may be. For example, assume that the old hub flange at the spoke holes is 11 in. in diameter and the new ones 2| in. ; cut these nine spokes è in. shorter, screw them the required distance, and fit in place as described above ; if correct, cut the remainder the same, the odd ninth spoke serving as a gauge for cut- ting them. The new hub may possibly be drilled a different number of holes from the old one ; in this case a new rim will also be required. Taking down American Bracket Axle.—There will be no particular difficulty in removing one crank and all the cones from the bracket axle of an American cycle, and as much will have then been done as is possible or necessary. The other crank and bracket axle is all one forging, so these cannot be disconnected, but with one crank and all the cones removed the axle should come out of the bracket case. Removing Sprocket from Coaster Hub.—In taking to pieces a Green and Houk back-pedalling hub, the axle can be taken out and the lock ring removed from the
