... Ich würde mit 11 zu 44 aber nicht sehr glücklich sein. Ist das Niedergewicht richtig? Stimmt das Aufgewicht? Hat es eine Möglichkeit, den Pilotenangriffspunkt zu ändern? Sind es recht große Hämmer - oder eher Kleinere, hebt die Dämpfung eher weit ab, usw.usw.

Thank you again for the translation. Would you please oblige once more?

Instead of capstans, the Schiedmayer has flat headed screws in the keys with a strip of felt on top. The stickers rest on the felt and are attached to the wippen with pins. So it is practically impossible to change the action ratio. I think the weights and damping are satisfactory in general.
I have taken another look at the 11 mm key dip for three reasons: you are not very happy with it, your previous point about sharps disappearing into naturals, and the quantity of original card punchings I had removed and not put back under the keys (the thickness of the pile outside the piano averages 0.3 - 0.4 mm per key).
Measuring E4 with calipers, the key travel up to let off was 10.3 mm with 40.86 mm hammer travel (3.14 mm let-off); at 10.7 mm the hammer fell back to 39.46 mm. G4 was set closer to the strings; key travel was 11.0 mm with 42.7 mm hammer travel (1.3 mm let off). G4 details: 10.08/41.1, 10.37/42.1, 10.56/42.51, 10.72/42.7, 11.04/42.7, 11.25/42.0.
With let off just over 3 mm E4 plays well at 10.6 - 10.7 mm but not at 10.5 mm. Touch and repetition seem good. Other test keys also play at 10.7 mm, even C4 which has a tendency to double strike. Its butt leather/jack graphite/usw. need attention.
The Schiedmayer hammer butts appear more rectangular than normal, with a sharper curve at the let off point. I wonder if the idea was to limit the amount of after touch required to 0.3 - 0.4 mm.
Would you be happier with 10.7:44?
