[pianotech] Refining Damper lift

[David Love]

First level the key end felt or replace if it's worn (which sometimes still
requires leveling), then set the damper timing to the keys, then adjust the
tray felt to get pedal lift uniform.  A capstan adjust system is very nice
in this case but paper shimming of the tray felt works too.

List,

 

After the initial adjustment of the damper levers, in a grand, so that the
dampers lift as one unit in general with the pedal and so that the damper
begins to lift when the hammer is approx halfway to the strings, how does
one go about the refinement procedure so that 1.  All dampers are lifted by
the key when the hammer is halfway to the string.  I find it difficult to
assess and know how to go about this refining.  And, 2.  All dampers move as
one unit?

 

I understand that one uses strips of paper of various thickness and that one
might need to iron felt.  What I really would like to know is the process of
assessing for refining and how one goes about the actual refining for damper
lift to hammer and to pedal?

 

Thank you,

Mark Davis
