Many piano friends have the phenomenon that the qin reel slips and the qin reel cannot be twisted. There are two main reasons for the slip of the qin reel.
One point is that the velvet buckle will naturally slip if it is often twisted in a very tight state, and another point is that the piano materials that everyone uses now are relatively good, such as red sandalwood, purple sandalwood and so on. If the red sandalwood used in qinzhen and the red sandalwood used in Zhenchi, the frequent friction between good woods can easily cause slippage.
The first point is to see if his velvet button is too tight. If it is twisted like a twist, then loosen it to a natural state and rewind it, because such strings are very loose. If you want to tune it to the standard tone and twist it into a twist, you must rewind the string. After winding the strings, fine-tune to achieve the standard tone. This step can be fundamentally solved, and the strings must be re-winding. If there is no twist-like phenomenon, we have to remove the zither and zither from the reverse side to see if there is frequent friction, and there is a smooth phenomenon. However, considering that it is difficult for many piano friends to wind the strings by themselves, you can also sprinkle some rosin to increase the friction, or use sandpaper to pry it open and then slowly grind it back and forth inside to increase the friction to solve the slipping phenomenon.
The second is that the zither can't be twisted. It is necessary to judge whether the position of the zither is in the middle of the pond. If the zither is skewed, it means that the eye of the string is slanted, and the upper and lower sides are not in a straight line, which increases the friction between the twisting of the zither. As a result, the qinzhen cannot be twisted, and the friction between the qinzhen and the pond is too large, which causes the phenomenon that it cannot be twisted. So we need to use 120 grit sandpaper to polish it (same as solving the slippage of the violins just now), loosen the trusses and then sand the edges, or we can apply Vaseline oil to it to increase its smoothness, but Once you apply too much, it may become more slippery, so it is recommended to use one hundred and two sandpaper for fine sanding.
These two points can be used to solve the problem that the zither cannot be twisted. If it is because of the string eye, the zither is skewed, etc. (this is something that the piano friends cannot solve by themselves), it is necessary to get the string eye to the qin workshop and adjust it again. A straight line, so as to solve its phenomenon.
If beginners want to solve the problem of slipping and unscrewing, they can consider replacing it with Xuanji qinzhen. Xuanji Qinzhen's patent has expired this year, and the inventor, Mr. Wu Yuehua, is also generous and did not extend the patent time. In this way, there will be many works similar to Xuanji Qinzhen in the market in the future, the cost performance will be better, and the market penetration rate will be better. Wider, this can effectively solve the phenomenon of the piano wheel slipping and not twisting.
