In each end cut a deep V, the sides of which must be carefully
smoothed and rounded with chisel and sandpaper. Nail a wooden rod, 15
inches long and slightly flattened where it makes contact, across the
centre of the board, taking care not to split the rod, and clinch the ends
of the nails securely. The projecting ends of the rods are held in the
hands while the string runs out. The projecting piece, A, which must also
be well secured, is for winding in. The winding hand must be held somewhat
obliquely to the board to clear the spindle. Winding is much less irksome
if a piece of tubing is interposed between the spindle and the other hand,
which can then maintain a firm grip without exercising a braking effect.
This kind of winder is unsuited for reeling in a string on which there is a
heavy pull, as the hands are working at a great disadvantage at certain
points of a revolution.
[Illustration: FIG. 123.--Plan of string-winding drum, frame, and brake.]
A far better type is shown in Figs. 123 and 124. Select a canister at least
6 inches in diameter, and not more than 6 inches long, with an overlapping
lid.
