Universal key for control of a piano
Because in the former Soviet Union there was a critical situation with service and repair of a piano, I bring to your attention a certain council for acquisition of the it is repair - an adjusting key. For anybody not a secret, as in Soviet period control of a piano, was the subject closed, unclear for the simple consumer and “put“ the client before an inevitable dilemma to invite for control of the expert if that was, or until the end of days to play on “sour fortepiana“ (I. Turgenev).
In this article would not would be desirable for me, to mention difficult and sometimes inexplicable system of this relationship: the adjuster - the client. The owner of the Soviet tool in most cases has very superficial knowledge about work and quality of own piano. The adjuster called to eliminate any defects not always has necessary qualification and the special equipment. It is good when, the invited master manages to adjust a similar “masterpiece of a muzsovprom“. And, the client is happy that the tool began to sound. The client, having own ideas of work of the master, considers that he paid dearly for service. The adjuster considers that IT costs, in his opinion, much more expensively, constantly complains about own poverty and misunderstanding of people.
misunderstanding is aggravated Now also with what in small towns and villages, because of absence of customer service, is good if someone in general practices, there is a situation of total absence of any information on a subject and at least approximate quotations on this type of service. In full ignorance on this matter there are regional centers and the cities. The reason is banal, the USSR is completely destroyed, and “the new state“, with all its functions, alas, so far, something is not visible. The parents who are sincerely wishing that their child comprehended the bewitching world of art, would only be limited to purchase / at a piano. In certain cases this piano, sometime and somebody, is allegedly adjusted. The child appears the hostage of incompetent adults and bad quality of the tool. Often similar contradiction leads to rejection of desire of the child in training in music. Financial side, of course, in this question main, but not always. Let`s assume that the parents having necessary means managed to buy technically serviceable piano, however, if not to adjust it, then as it was told earlier, to sense from occupations on it will not be. And, here that also arises an immemorial Russian question: “What to do? “
Further, will be a question of how to be in the circumstances when at your place costs a piano, but it is correct “refuses to play“. To you do not remain there is nothing another if there is no adjuster and, in the short term, it is not expected how to adjust him for occupations independently, naturally, if you have at least ear for music rudiments, and you imagine how it becomes in principle. The most important what it is necessary to begin with, so it to make an adjusting key. The matter is that I would not advise, to buy a factory key which in hands of the skilled adjuster is more convenient, however, owing to existence of some constructive shortcomings, can the reason of irreversible damages become caustic. You need to serve own tool and there is no need to spend money for an expensive key which is necessary to the professional - a remontirovshchik.
Cannot try to arrange the wrong sounds by means of passatizhy or any other devices. As in my practice there were cases when daddies took passatizh in hand and tried to adjust the tool. Result, alas, as a rule, negative. The notes sounding not truly did not begin to give the necessary tone, and splittings, that is a special core on which the string is recorded, unfortunately, damaged. On such splittings the professional repair key refuses “to climb“ and means a lot of work it to dismantle and again to establish into position. So with what to begin
? Or you find splittings of the necessary size identical a splitting, established on your tool, or by means of a usual cap wrench, naturally, previously having released is caustic from a string, unscrew the MOST extreme (on the right) is caustic on own tool. The second is more preferable as the key made on a splitting of your piano will work most qualitatively and without serious consequences for all kolok. Having available it is caustic, you need to address on plant which is engaged forge - press works and heat treatment of metals. It is necessary to specify in a task that the key was made in a form a splitting. Main technical characteristic of a key: chromonickel steel of type 18XHBA, or something similar according to characteristics is desirable. The key has to be made with small “weak point“ between working sides of a key and caustic. After production the key has to be subjected to heat treatment to the hardness of working sides not menee180 by HRC.
Is important also key geometry. For a start you need to make a key which diameter of a head slightly more than the size of a side it is caustic, literally on 0,5 - 1,0 mm. Which durability and hardness if it was made according to my recommendations, will quite provide setup of your tool and it “will approach“ all splittings, even in those places where distance between splittings absolutely small. I in the practice of repair work use several similar keys with the increased diameter of a head, but it is already following stage of your “professional“ preparation as adjuster.
B what essential advantage, the key made in such a way, over so-called “classical“ or “Swedish“? The matter is that in our situation, the key made on a splitting will solve a problem not only settings (a temperation of sounds), but also will allow to carry out some incidental is repair - recovery work. Namely, replacements of the torn strings and strengthening of a system. Our key, possessing high strength qualities and firm sides, it is capable to provide full contact with caustic, excludes even insignificant mechanical damage of external sides a splitting, smyaty its sides as its working surfaces have contact with all conical head a splitting, but not with local, its small site as at standard keys, during the work as which, owing to the considerable efforts made for a limited site it is caustic, some residual deformations and damages of sides are not excluded it is caustic. Internal sides of “our“ key completely repeat the standard sizes of kolok, are made on a cone. That is, except durability, it also universal as will be suitable for setup of any tool, the head of a key will without serious consequences provide necessary fixing with splittings of any size which slightly differ at different tools. Order
, produce a key on the way offered by me and seize knowledge of control of a piano. If at production of a key all are observed, the characteristics described earlier, and to you “the bear did not step on an ear“, then the good system is provided to you!
