size=2>> Dear List,<BR>> <BR>> I have a 110 -year-old B with =
a 35 year
old board (NY: Camilleiri? <BR>> A&C?), with whose voicing I've =
hit the
"wall". This is the main <BR>> concert piano for one of my summer =
music
programs, and the piano <BR>> lives over the winter in the =
uninsulated
concert shed. I believe <BR>> (based on 8 years of taking care of =
this piano)
that I've hit on the <BR>> best musical use of the resonance in that =
board,
but still the 5th <BR>> and 6th octaves never balance satisfactorily =
with the
rest of the <BR>> piano. (35 y.o. board & block, 15 y.o. =
stringing, and 6
years ago, I <BR>> put new action parts - NY hammers. This summer I =
did sell
them <BR>> Pianotek's turnbuckle brace.)<BR>> <BR>> Underneath, =
the
crown has collapsed. I've got an M-shaped board: the <BR>> bridge has =
pressed
a downwards ridge into the soundboard, all along <BR>> the treble =
bridge,
except when the bass bridge stands behind it <BR>> (between ribs #2-5 =
counting from the bass corner). Here the long <BR>> bridge has crown =
under
it, and it's the bass bridge which furrows the <BR>> board. The board =
BTW,
doesn't show compression ridges.<BR>> <BR>> On top, there's =
respectable
downbearing *and* front bearing <BR>> throughout (the only exception =
to front
bearing is at the mid-treble <BR>> break where front bearing =
disappears, but
downbearing is still <BR>> respectable.<BR>> <BR>> Having =
listened to
some fine new factory fresh Bs at Marlboro this <BR>> summer, this =
board's
resonance needs to be better. Based on the crown <BR>> readings, I'd =
tend to
say that we shouldn't expect anything better <BR>> from this =
board.<BR>>
<BR>> That judgement call aside, it's still interesting that things =
should
<BR>> look so good from the top side. I know when a crown has =
reversed and
<BR>> bridges have rolled that such a board can give false =
positives on
<BR>> downbearing. But I would expect that to be accompanied by badly =
<BR>> negative front bearing. Which is not the case here.<BR>> =
