How to Repair Badminton How to Repair Badminton

1. Separate the feather and the ball holder of the old badminton, and take down the ball holder and wool available on the old badminton for later use.

2. Cut off the broken hair on the badminton to be repaired, and pull out the hair rod inserted in the ball holder with needle-nosed pliers.

3. Drop a small amount of glue into the ball socket, and twist the wool sheet to make its inclination angle the same as other wool sheets.

4. Find a hemisphere with the same size and specifications as the badminton, put the badminton on the hemisphere bracket, and ensure that it is fixed with glue.

How to choose badminton:

1 and the weight of badminton is between 4.74-5.5g, generally 4.9g, 5.0g and 5. 1g, and some other units are used to mark the weight. The common symbol is 49 (4.9g) =76 50=77 5 1=78. Relatively speaking, the heavier the ball, the faster it flies. Use balls with different weights at different altitudes and temperatures (feathers need to absorb water and deliquesce, as well as air density). The higher the altitude, the higher the temperature and the lighter the ball. The most commonly used is 5g ball (18-27 degrees Celsius).

2. Badminton consists of 16 feathers, the length of which is 62-70 mm, and the length of each ball's feathers from the ball support surface to the tip of the feather should be the same. The top of the feather is round, with a diameter of 58-68 mm. Made of duck feathers or goose feathers. Relatively speaking, goose feathers are more durable than duck feathers. But it's also much more expensive. Hair can be divided into straight hair (Mao Mao piece as thick as Yashilong No.5 ball on both sides of the pole), oblique hair (Mao Mao piece as thick as Yashilong No.7 ball on only one side of the pole) and curved hair (hair on both sides of the pole but thin as Double Happiness 402), and straight hair is the best. According to the appearance, thickness and identity, the rough pieces are divided into grade one, grade two, grade three and grade four, which are used for different grades of badminton. No matter what kind of hairball is, it must bend in one direction, either to the left or to the right, in order to rotate stably during flight. Feather distribution on goose wings: from outside to inside, 1~3 are half feathers, making low-level balls; No.4 ~ 10 is a knife feather, which is a medium and high-grade ball; 1 1~ 16 is a nest feather, making a low-grade ball. It can be seen that only 14 feathers on each goose can make middle and high-grade balls (about).

3. Badminton tray should be made of cork (actually a kind of bark), and the outer bread layer is made of PU material. The diameter is 25-28 mm, and some of them are made of foamed plastic, so it is best not to buy them. At present, only the feather insertion part of the ball holder is a whole piece of cork, and some even have a thin layer or none at all, and other parts are cork residue. A good cork tray will not become soft or broken no matter how it is smashed, provided that the weight is qualified (unlike Shuangxi 40 1).
