The customer sent a Bright Sword 12L. The silver and blue color feels very fresh. It is a bit better than the old Bright Sword 12 in my impression. Before threading, the thread hole was checked according to the usual practice, and several positions collapsed, so I persuaded the shooter to replace the nails. Five hundred words are omitted in the process. The following is the process of installing the nails.

1. The unbelievable Bright Sword 12L, the line holes that can collapse, have collapsed to varying degrees;

2. If it is only the collapse in Figure 1, between replacement and no replacement, I would never think of consuming saliva for the shooter to replace the nails, but the two holes on the top have collapsed too much. I You can only tell the racket owner that if you don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t change it, you can now count down the racket, and there are only about ten times of stringing life left;

3. The six nails used are YY 416 L3, pure large holes, and are the original six nails of the AT700 500 70mg titanium tenth-class racket model. When comparing the hole positions on the Liangjian 12L, it was found that some hole distances were incorrect, which has been done. After the psychological preparation of cutting a knife in the middle, the last pilot hole was found to be fully installed. The elasticity of the original nail body was beyond my imagination. It is no wonder that after so many years, there are almost no such nails on the market. Fake products, it should be because the production threshold is not low; the second nail used is 416 W1, in fact, there is really no difference between W1 and W2. I have been mixing them for so many years, and they are all designed with one large hole and one small hole. W3 is pure The big hole is not used here;

4. Note: L1 2 4 with large and small holes, these three types of six-connected nails, do not worry about the installation direction, because the direction is reversed, the large and small holes will not match up, but the L3 with pure large holes is different, they are all large Hole, the direction cannot be determined by the size of the hole, so I can only tell you the direction after the DIY is successful, that is, the number-letter should be on the YY LOGO;

Note: Be sure to prepare an awl like the upper right corner for the guide hole when installing the nails. Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t think about installing them with bare hands. Borrow the original nails of other brands and models for DIY, not so simple.

5. The effect after successful installation and after installation is just right, almost tailor-made.

6. The racket head can be used with a strong bow strip or ten nails on the racket head. The strong bow strip has 22 holes, which can cover the racket head and both sides of the racket head. But it only covers ten holes on the head of the racket, and you can buy it on demand.![](https://img.alicdn.com/imgextra/i1/11293736/TB29UyFghHI8KJjy1zbXXaxdpXa_!!11293736.jpg)
