A piano is a musical instrument that stood in every Soviet apartment 10-20 years ago. There are music lovers today. But every musical instrument requires tuning, the piano is no exception. We suggest you make your own piano key.
Watch the video how to make a piano key yourself.
For the manufacture we need:
- Three migrant heads for the key;
- handle.
Many tuners of Soviet pianos erased the edge. The classic key has a handle and a notch for adjustment.
Kolkak at the piano has the shape of a cone, if with an ordinary ring spanner we can grab part of the face, so that all the power load is distributed to a small part of the stake (1 cm).
It is advisable that the kolkak is completely seated on the key, as shown in the picture. The keys that are presented in the bazaar do not have backlash. The peculiarity is that if there is no backlash between the sides of the key and the tuning ring, we are in danger of folding this side.
We should not have an 8-faced key, but a 4-faced one, so that it completely repeats the shape of the split. He needs the recess, which will be on the key, to fit into different parameters. It may happen that we are able to work with a small asset and the key simply does not fit in there.
It is convenient to work with a universal key, it has 4 faces and the distance taken in a circle makes it possible, as if we had no peeps in the piano - the next one will not.
If you look at the following figure, you can see, the thicker the wall, the less wear.
There are universal keys that you can configure almost any actu in the piano, but there are other keys that are used in rare cases. If you compare two keys: universal and small, you can see the difference between its walls.
When we have the edge of the pegs very close to each other, you can use it to tune the piano to the desired tone.
Such keys were used for the piano of the late 20th century.
Now the keys are used, where the octahedron is at the end.It has a comfortable grip and a migrant head.
Also used to tune the piano wheel. They are smaller than a standard key.
If you have a regular tivar at home, then a peg is refueled inside the tibar, and the blacksmith shakes it all in a cone. The peg inside the key should not wobble, it should stand exactly along the diameter of the inner surface of the key.
Otherwise, if the metal of the key is soft, then it can simply remain on the key during operation.
