Sooner or later, a person who has a piano will need to dispose of it. This situation happens most often due to the wear of the technical parameters of a musical instrument. The most common problems are: poor fixation of the peg mechanism and the appearance of a significant crack in the cast-iron frame.
Of course, in this case, the piano cannot be sold, and therefore the question arises “What to do?”. One of the easiest options is to dispose of the tool in a landfill, but it is quite costly financially. Probably the most profitable and reasonable in this situation can be called the surrender of the piano for scrap, however, for this you will need to properly dismantle it.
This work can only be done by men who have the skill to work with machinery. For the complete disposal of the piano, you need several different screwdrivers, 2 crowbars (small) and a tuning key. The optimal place for disassembling a piano is a non-residential premises, but, in most cases, this operation is carried out in an apartment.
Therefore, it is important to free the room from unnecessary items, at the very scene of the action it is recommended to cover the floor with several layers of rags, first resolve the issue of lighting, and determine a place for storing piano parts.
First you need to remove the bottom and top covers, they are fixed with two turntables. Then, remove the cornice (the cover that closes the keyboard) by moving towards you. Next, you need to pull out the hammer bank, a kind of hammer mechanism, it is fixed with two or three nuts. Once you’ve removed the hammer action, the keyboard strap must be unscrewed from both ends so that the keys can be removed.
When removing the keys from the stem, it is recommended to make a swinging movement to the right and left and lift them from the ends towards you. When all the keys are removed, you need to unscrew 2 bars on the left and right (there was a keyboard strap on them). Next, you need to knock out the side consoles using a mallet.
After that, you can begin to unscrew the keyboard frame itself. Some of the screws are located on the top and five or six on the bottom. At the end of this procedure, the piano must be put “on its back” and beat off the basement floor, as well as the side walls on both sides.
In the process of unscrewing the pegs and when removing the strings, be very careful and careful. The bottom line is that until all the pegs are unscrewed from the virbilbank, it is impossible to free the cast-iron frame from the back of the piano. It is recommended to start unscrewing the pegs from the winding strings, which are located on the left. Using a tuning key, you must first loosen the string, and then use a thin but strong screwdriver to remove its end from the peg.
In order to make it easier to unscrew the peg freed from the string, it is necessary to pour plenty of water on its wooden seat. Having unscrewed absolutely all the pegs, having unscrewed all the screws that fixed the cast-iron frame, you can feel that the frame is “playing”.
Next, you need to push one crowbar on the right, and the other on the left, between the resonant deck and the frame, lifting it alternately, then to the left, then to the right. If everything is done correctly, then the cast-iron frame should “slide” to the floor. It will not be difficult to disassemble the resonant deck, since now it is possible to deploy it in different positions.
