Can a single bow catch prey?

You can shoot some small prey, such as sparrows and cicadas. The more rubber bands, the greater the strength.

A single catch bow is a slingshot. Slingshot is a cold weapon or a game tool. Slingshot is generally made of branches in the shape of a "ya", with epithelial tendons at both ends of the upper end and skin blocks wrapped around the body in the middle. Strength depends on the tension of the rubber band. The greater the tension of the rubber band, the greater the power of the slingshot. A long-range weapon that fires projectiles with a bow. In ancient times, projectiles were mostly used for hunting. In ancient poetry, there is a description of "breaking bamboo and bamboo and flying soil to eat meat" It means cutting bamboo to make bows and shooting birds and animals with clay balls. Later, it developed into a martial arts instrument. There are many ways to launch a projectile, such as "Su Qin carries a sword" and "Zhang Fei shoots a horse". Zhang Xian, a Shen Lu legend who sent his son to China, is an expert in using slingshots. Leonardo da Vinci in Europe also suggested launching smelly bombs with slingshots. Because it is a dangerous weapon, please don't shoot people indiscriminately.

manufacture

1, wooden slingshot frame: generally made of tree forks on willow trees. Choose the right fork. When you stop your hand on the fork, you can see that it is an isosceles triangle. Pay attention to leave more space when cutting to avoid cutting. Remove the skin from the cut fork and dry it naturally, not in the sun, because it will crack in the sun. Arrange the shapes in order and twist them, and you will get the belt.

2, the production of iron slingshot frame: If you have never seen a slingshot made of wire, it is more complicated to teach you face to face.

3. Rubber band: generally the kind on the valve core of bicycle tires. Buy 4 pieces, each cut into two pieces with the same length. If possible, you can use a bladder.

Now there are special slingshot rubber bands on the Internet, such as Wusuli River and Panda rubber bands, which can improve the quality and ballistic stability of slingshots.

4, elastic pocket: you can go to the place where shoes are repaired and buy the best cowhide.

Precautions for use

1. The tension of the heavy bow is large, and the elbow holding the bow is hit. When the joint is reversely impacted, the rubber band suddenly contracts and diarrhea, which is easy to cause injury. When using a heavy bow, the rubber band can be slightly longer to reduce tension, the arm is not straight, and the bow is not fully stretched to avoid injury. After getting used to it, you can return to normal requirements.

2. The wrist is not easy to grasp and unstable, so you can wrap it properly with inelastic canvas belt to strengthen your strength.

3. To some extent, the main factors affecting the accuracy are: whether the forehand is correct, the control of the bow arm and whether the bow is full.

4. Whether you can hit a drillable hole (the diameter is 1%) is a necessary condition for you to continue to practice accurately. As the most important thing to master the long-distance shooting, it is most important to play the trajectory of small arc. I have made considerable efforts here.

If it is difficult to hit the target size on this paper, you can hang a bigger target bottle first.

6. Complete long-range aiming before pulling the bow. The bow is slowly pulled, and it will be fired as soon as it is fully pulled. The bow pulling time is about two seconds. Of course, the previous practice may take longer, and there will be a pause after the full bow is pulled.

7. You must understand the meaning of hitting the target. Don't think that shooting at such a long distance is not accurate, that is, shooting at the target bottle or practicing the control and trajectory of the slingshot. Try to get into the exercisable position, and you can hit a 40-meter exercisable spread. It is much easier to try to hit a target of 30 or 35 meters, and it is much faster than practicing shooting directly at a target bottle of 35 meters.

8. The light bow swing is not correct, so it is not easy to play more than 30 meters for practice.

When the target is far away, the trajectory arc is large, so it is impossible to judge aiming according to the direction of the rubber band. It is an aiming method that automatically adjusts the slingshot direction according to the target position, feeling and experience. Small targets over 40 meters, such as 50 meters, are not easy to hit, let alone slingshots, even guns, slingshots are artificially fired, which is even more difficult to grasp. Moreover, the slingshot has no sight, and even if it does, it is believed that it is not allowed because of elasticity and man-made instability. Therefore, long-distance slingshot shooting is entirely based on a lot of practical experience in ballistics. It is a natural reaction to feel and perceive by looking at the position and distance of the target and decide what angle and posture to launch. Therefore, to hit a slingshot from a long distance is to hit the target with intentional aiming. This is also one of the reasons why the slingshot can't hit the horizontal. When hitting horizontally, the slingshot blocks the line of sight and cannot see the target, so it is impossible to accurately judge the aiming.
