How long does the traditional slingshot 80 saw rubber band use?

Traditional slingshots are generally stretched in the middle and long distance of 22-24cm, which can meet the stretching distance of 80cm. The short slingshot is generally related to the individual's height and arm span. If a person's height is about 170 cm and the short pulling distance is 70-80 cm, then the length of the rubber band should be about 17 cm.

The thickness of leather depends on the diameter of steel balls used. Compared with the No.8 ball, the thickness of the leather should be 0.5-0.6, so that the shot beads will not have bad trajectory or handle. The taper of rubber band is generally 20- 12.

Optimal configuration of short stretch flat skin

Whether beginners or skilled people, the choice of rubber band tension involves the configuration problem. At present, the popular saying is that the traditional bow uses four strands 1745, and it is more suitable for beginners to choose four strands 1842.

1745 four-strand short draw can drive No.9 bead, 1842 can take No.8 bead at most, but when it comes to No.9 bead, the kinetic energy is slightly worse. Of course, at present, all kinds of competitions limit the steel balls to no more than 8 mm, so too much tension is just excess kinetic energy. Beads with large pulling force are not only unstable in the front hand, but also difficult to pinch the pocket in the back hand, which makes them feel unable to pinch.
