On some keys, I cannot adjust the hammer drop after the escapement; I fully tightened the repetition spring screw, but with no result. After the escapement, the hammer remains too close to the string, less than a millimeter; where did I go wrong?

I think I didn't turn the right screw, I would need a small manual with instructions on how to use each screw or button.

Thank you for the information.

The screw is located right at the top of the forcola. Anyway, if the depth is excessive, then the hammer rises back up after falling,.....annulling the fall

Thanks Pianoexpert for the clarification, I am trying (with great difficulty) to record my piano, I join my voice to the chorus of many who are asking for a small manual, not for expert technicians, but for (simple) pianists or

(simple) amateurs who can't stand calling the usual technician who, as usual, achieves nothing...

I am trying to address this long-standing problem. One should not always think that many skills can be acquired with a simple manual. It is true, yes, that everyone can and has the right to try their hand and perhaps become [proficient], but, generally, because our instrument is very complex, the tuning/regulation should be performed by an expert. I do not believe that a good technician "cannot pull a spider from a hole" [is incompetent]. Of course, there are "amateur" people and expert people, as in all things. Piano adjustments and regulation depend on interventions that can be interdependent with one another, and it is not enough to simply "follow the instructions for use."

This Forum was created with the intention of helping pianists better understand how their instrument works and arrive at determining the reasons for any potential dissatisfaction. This will facilitate dialogue with a good and prepared technician who will know how to intervene on the instrument, seeking to make it "express" itself to the best of its possibilities.

By watching my video tutorials, you can also obtain technical information to use directly on the instrument, but sometimes a small error is made which, however, acts in a specific way on the expected final result. There are many books and videos out there. I recommend Reblitz as a basic text, written in very understandable English, for example.

Considering also, excuse me for intruding, that sometimes it is not enough to "turn the right screws in the right way," because besides the wear problems that need to be resolved, one must also evaluate potential defects due to the mechanical positioning not being performed correctly at the factory and the consequent incorrect balancing. Example: the Bechstein uprights from the 50s produced when they resumed production after the war (the old experts were no longer around), the Kawais from the 70s, and sometimes even products from even more prestigious companies, depending on the craftsmanship performing this extremely delicate operation. There is not always a standard and for these or other reasons, the millimeters provided by "recipes" may not work! Because while it is true that the action is supplied by Renner or another equivalent company already assembled, and it is true that the keyboard is supplied by the keyboard maker according to the manufacturer's design and well-calculated (not always), the real magic is performed by whoever bores the keys for the pins and places the action in the right spot, whoever bores the hammers at the right height and calculates the point of percussion etc... certainly today with CNC technologies everything is more standardized, everything is more repeatable, and yet not all pianos are equal.

That is why a manual is not enough, because it does not explain the "compromise" that is acquired with years of practice on actions and on pianos.

The mood of the player should also not be overlooked, an aspect that significantly influences our perception of our instrument from one day to the next.

Thanks a million for the answers, I apologize for the somewhat strong language and I am certainly going to purchase the Reblitz, at least I will educate myself on the subject.
