The crank should be as light
as is consistent with sufficient strength, and be balanced so that there
shall not be unpleasant vibration when the string runs out fast, and of
course it must be attached very securely to the spindle.
What will be the front of the framework must be rounded off on the top
edge, which has a wire guide running parallel to it (Fig. 123) to direct
the string on to the reel; and into the back are riveted a couple of eyes,
to which are attached the ends of a cord passing round the body, or some
stationary object.
[Illustration: FIG. 125.--String winder in operation.]
A pin should be provided to push into a hole at one end of the reel and
lock the reel by striking the framework, and it will be found a great
convenience to have a brake for controlling the reel when the kite is
rising. Such a brake is easily fitted to the side of the frame, to act on
the left end of the reel when a lever is depressed by the fingers. There
should be a spring to keep it off the reel when it is not required. The
diagrams show where the brake and brake lever are situated.
