Damper release adjustment

From a distance it is difficult to suggest, because in these adjustments, a minimum shift makes the difference. One must be on site. The regulation of the dampers is "difficult".

If you have already solved the sound problem, I advise you to leave it as it is

I realized right away that it was going to be a difficult thing, unfortunately

The problem now is that they do not lift at the same distance as the others but remain a little further forward, reaching the string sooner

Sometimes you have to act on the pins and sometimes on the hammers (if vertical). On the grand, you must act on the leveling

Alright, I will do a few more tests

I hope to succeed, even though the problem occurs when I use the pedal, so I believe it is a problem with the action parts that need tuning

With the Forte pedal completely depressed, how far must the dampers move away from the strings?

a millimeter or two compared to the depth of a black text

And in the choruses, up to which note must the wedge-shaped felts with a central cut be placed?

On my vertical [piano], they start from Eb3 and this defect goes up to about A3

At the moment there are felts for the highs which obviously leave an aura in the resonances and do not immediately block the sound

Is it normal that when playing loudly, in the choruses, when the wedge dampers with the center cut block the strings, a small squeak is heard?

How to resolve this?

I thought about "stretching" the two "little teeth" that fit between the 3 strings... I don't know if this can solve it

The chirping can originate if the damper is not well centered and adjusted in all directions (longitudinal and transverse)

Agreed, I solved the problem by perfecting the centering of the damper and stretching the felt tips a bit

Thanks again!

Is there a treatment to be done before installing the felts?

For example, moistening or ironing them?

The previous felts that dampened the choruses were all flat like those for the highs and worked excellently (not perfectly)

Now, changing them, I am forced to use wedge-shaped felts with a central cut at least for the first 8 notes of the choruses because once the flat ones were mounted, the sound damping was not sharp

I am asking this question out of curiosity

It depends a lot on the right encouragement and the quality of the damper

All right Mr. Paolo, in the end it was more convenient for me to change them all and the work is optimal anyway with the wedge ones...

Thank you for the precious advice
