So what to do, and what to do, a man who comes up with problem of urinary system? The main cause of urinary system, the piano is a Soviet-made considerable wear seat chopping. If you say simple words, a hole in verbilbanke, which was originally provide the necessary friction to set it in the groves, under the influence of multiple settings and time-consuming operation, it lost this power for long enough and often very difficult years of operation. Sela Ward shines more light on the discussion. Correct say, partially or completely lost its primary function, namely to provide the necessary frictional force, which provides good traction "verbilbank – peg." Most often, one can observe that the splitting of the piano tilted at a slight angle downward. The modern practice of repair, with few exceptions, suggest or incite nefiksiruyuschiysya peg with a regular hammer (like a regular nail deep sink), and thus way we provide the necessary friction "verbilbank – peg", or completely remove the pin and set in its place, a larger diameter pin (a nail set thicker). Moreover, the newly installed pin, rammed into a seat with a hammer. In a question-answer forum Vladislav Doronin was the first to reply. On the one hand, all right, "eaten" seat verbilbanka replaced by a larger diameter pins, and thus provided so we need friction. However, this far from it, and here's why.
In practice, I very rarely come across a piano, all the pegs that do not provide the necessary friction. Rather, such a defect is found selectively in different sectors tool. For example, do not hold the system 5.7 sounds small octave.
