The total amount of action restoration is dependent
upon the amount of use or misuse the piano has had. Felts hardened
with age and pressure, or worn and moth eaten must be replaced to
insure a quiet and smooth playing action. Only the finest quality
felts are used.
Action replacement parts by Renner are chosen for
their high quality, exactness and longevity. Key and key frame replacement,
should that be needed will be from the manufacturer best suited to
fit the need.
Key work and leveling is the foundation of a solid
and lasting action regulation. The keysticks and frame are thoroughly
cleaned and repaired. Felt bushings and frame rail felts are replaced
to insure precise and quiet key movement.
Often the key stick needs repair. This involves
a re-wooding process that returns widened key spacing to the correct
original specifications. Widened key spacing is caused by improper
top replacement and wood shrinkage.
Key top replacement choices include fine grade acrylics,
legal ivory, pre-historic mammoth tusk ivory and bone. Sharps of original
solid ebony are reshaped and sealed. Replacements choices are solid
ebony, rosewood/ebony and plastic resin.
