Piano Action Problems in Kohler & Campbell Player
By Piotr Barcz
Ben Gottfried mentioned [250715 MMDigest] that damper regulation is
important, which I did forget to mention. My piano has a bent damper
rail so when the pedal is depressed (and it has a lot of travel) the
treble dampers lift first and then the bass dampers will lift but
only after the treble ones are way off the strings.
I'm not sure what there is for a solution other than pulling that rail
and having a metal worker bend it straight again.
I do intend to have the dampers regulated so the pedal lifts them high
but so the actual spoons don't push them off almost at all until the
hammer is practically hitting the string and then checked, especially
with how the sustain pneumatic already struggles. I'm going to try and
make that as efficient as possible down the line.
The hammer check distance I do try and keep rather close because of
the forementioned ease of playing quietly when there's control of the
hammer almost to the string itself (bobbling problems taken into
account, naturally).
Thank you, Don Teach, for your input as well! :)
