[pianotech] Bass dampers

[Delwin D Fandrich]

The blocks have moderately more mass (which is important, especially in bass
dampers) but require sometimes extensive wire bending. Whether this is a
problem or not depends on your skill and experience. Factory workers do the
job in a couple of minutes (at most); I've known technicians to take a
couple of hours and still not do as good a job. The dowels (barrels) are-by
far-easier to install and regulate but have very little mass. Usually when I
hear from technicians having problems with ringing dampers in the bass
section it is with a damper system using wood damper barrels.

 

The best of both worlds are the brass damper barrels offered by several
European piano parts suppliers. I've been encouraging PianoTek to stock them
for us but don't know if they have them as yet.

List,
What are the advantages of using the dowels versus blocks when installing
new dampers?
Also, has anyone ever replaced a set of damper levers, and how challenging
was the wire bending?
