Saw 1.4m slingshot leather configuration
Slingshot is a toy that we used to play with when we were children. The rubber band used for slingshot directly affects the tension of slingshot, so the key to slingshot is the choice of rubber band, which is beautiful and durable, and the strength is different, and the suitable rubber band is also different. Let me give you a brief introduction:
The model of slingshot rubber band is generally represented by four digits, such as 2040, 1842, 1745, 2550, 3060, etc. The first two digits represent the diameter of the inner hole of the rubber band, the last two digits represent the outer diameter of the rubber band, and 2040 represents the rubber band with the inner hole 2mm and the outer diameter 4mm.
The tension of the slingshot rubber band is mainly related to the rubber band model and the number of strands. For example, the four-strand tension in 2040 is 1, then the four-strand tension in 2550 is 1.56, the four-strand tension in 3060 is 2.25, the two-strand tension in 2550 is 0.78, and the eight-strand tension in 1745 is 2.89. Generally, the four-strand rubber band group belongs to the light bow, and the eight-strand rubber band group belongs to the heavy bow.
