The main point of repair "of the triple bundle" decide according to quality standard, mortgaged, directly at the time of making the piano. For even more details, read what Chuck Berry says on the issue. Even an experienced repairman immediately or give an objective answer to the question "What materials and technologies have been used in the manufacture of the instrument?". And that really talk about a man from the province, which has a very superficial understanding of the subject piano tuning and repair of its basic mechanisms, in particular? Such a "novice amateur," due to circumstances forced to do repairs Pegs mechanism can that says "a lot of mangled wood" or even ruin the tool, relying on the "classical method" hammering chopping. The danger would lie in wait for him and procedure of "small copse lined" as a short period of time, most likely, "nestroyuschie", lined them splitting again will go to the "free floating". The reason for the failure of this method lies, as mentioned earlier, in ignorance of a novice, the basic laws of physics, and all the ensuing low-skilled activities. Not having an objective analysis of why the peg does not keep order, "beginner amateur" face problem "to treat a patient, but how?". Why do I put under serious doubt that such events will be forced to engage in the process engineer. The answer is obvious – too ungrateful thing to do is repair piano, and most importantly, non-monetary. Rather, such operations will be the man, music teacher, whose administration school of music, by force will be obliged to "restore order piano." So referring primarily to this category of citizens, professionals, please – repairmen, spare the time and hassle, and no further read my "harmful to their psyche," Fiction.
