Do you know how the piano works? Of course, you press a key and a hammer hits a rope, but what are the key points of this operation? In the 3D printed scale model of a small part of the [mechanical] grand piano keyboard, the complexity of the ingenious mechanism is exposed. The “big” difference here is that the length of the piano is unknown, only referring to any non upright. These operations are the same, but the layout is different to save space.
The keys of the acoustic piano are much longer than those shown – they are long levers that can do a lot of work, including using their own silencer. The really interesting part is a mechanism that allows repeated playback of notes without first releasing the key. The same mechanism allows the pianist to speak softly, loudly or in between according to the amount of pressure applied.
So you know that the hammer hit the rope (or, in this case, the rod), and you might think it would step back and make the rope sound. But there is also a complete system to keep the hammer nearby for repeated knocking, as long as someone holds the key. Make sure to view it in the build video after the break.
[mechanical] will certainly stand up and applaud, because they said in the video review that they would release the STL file after completing the compilation Guide (!). What a wonderful Encore it will be.
There are many ways to crack the acoustic piano, but don’t think you can substitute in the guitar string.
