Réglage Schwander

Post by huguenant »

Bonjour
J'ai récupéré un Gaveau n°1 de 1925 équipé d'une mécanique Schwander. J'aimerai obtenir les cotes de réglage de cette mécanique. Merci au participant qui saura m'instruire !
Cordialement

Blow 47mm
Dip 9.5 mm
Sharp height 12mm
Sharp dip 10mm
Set off 3mm
checking 15mm
The above measurements are not finite as a lot of it depends on the age of the piano action. The key height from the lock rail will vary a model to model depending on how the keybed has been set up.


Coup 47mm
Plongeon 9,5 mm
Hauteur pointue 12 mm
Tranchant pointu 10 mm
Décoller 3 mm
vérification 15mm
Les mesures ci-dessus ne sont pas finies car elles dépendent en grande partie de l'action du piano. La hauteur de la clé à partir du rail de verrouillage variera d'un modèle à l'autre en fonction de la configuration du clavier.

Thank you Barrie for your answer, that I found only yesterday.
I have some problems withe the translation. The technological vocabulary about mecanism of piano is not known by google.
I think that "Blow" means for the piano in french : "chasse",
"Dip" means ""rechute",
"Set off" means "échappement".
I have no idea about the specific signification of "Sharp height", "sharp dip", "checking". I you have time to explain ?
Sorry for my bad english speaking, and once more thanks for your answer.

Blow 47mm (this is the distance from the noise of the hammer to the string)

Dip 9.5 mm ( this is how far the natural key goes down.)

Sharp height 12mm ( this is the height of the shop from the natural key hight)

Sharp dip 10mm (this is how far the shop goes down)

Set off 3mm or let off (USA) (this is the distance the hammer travels to the string before the set of buttons trips it, it stops the hemmer from blocking)

checking 15mm (/USA catcher) (when you play a note firmly it hits the string then it bounces back and he's caught by the check )


Hope that helps.
