Corrosion of Piano Action Springs
By Jurgen Goering

In response to Paul Tramm's query about moisture-related corrosion of
piano action springs:

I suggest not to replace only the broken springs if "quite a few" are
broken.  Replace them all.  This way you won't have another one
breaking every week for years to come, and they all have the same
properties, such as spring tension, etc.  The additional investment
(your time plus the extra two dollars) is well worth it for the peace
of mind that you won't have to replace a spring again for a long time.

Also, after the action is thoroughly dry, check all the center pins
carefully.  More likely than not, there will be seized up centers which
need repining to avoid sluggish, slow, or soft notes.

Keep in mind that the best restored player can only play to the limits
of the piano action.

If you have any doubts about the piano's performance capability, call
in a piano technician.
