Dear Pianoexpert, I saw online a type of string regulation that is truly special; at least for me, I was able to observe that the soundboard of this grand piano had the string terminations in a coaxial position to themselves, located on a specific rectangular bridge; tuning is done with a special key.....can you please tell me something about this?

THANK YOU SO MUCH

A big hello

If I understood correctly, these are screw-type tuning pins. I saw one of these instruments from a collector. However, the system does not seem to work well. The pin "lives" well in the wood. When it is turned, friction occurs and the subsequent "rest" with springiness fixes its position. The screw, even if it has a "refined" and "micrometric" movement, lacks this final phase, which allows it to counteract the "drop" of the string during vibration. In short, I would say that the "crude" system of the "small pin" in the wood—turned, rested, and stopped by the wrist movement of the tuner (who is sensitive to this fixing system)—works marvelously. ...(unless the holes have become loose)

Saverio absolutely must learn to play the piano. In a few years, I am sure that if he continues at this rate, he will be able to build one of his own! eheheh 😆

Ah, Ah; ah if only!!! I am just a simple enthusiast of this FANTASTIC INSTRUMENT and I try to understand a little something from our legendary Pianoexpert, and that is why I keep questioning him; you know, these days, finding capable people like Paolo and Simone from whom one can only "learn" is a lot for me, and for this I THANK YOU!!

Greetings
