<DIV>Thanks for the clarification; I was seeing it in the wrong direction :-).
As far as "Wapin-izing" the piano, if you're happy with what you've gotten so
far, maybe let sleeping dogs lie (lay?). </DIV>

<DIV>Paul,</DIV>
<DIV>I was talking about getting more pin into the bridge, hopefully where
the wood might not be as affected by the WD 40. I left the exposed
pin height the same as the neighboring pins. I think that due to the
pin being much tighter and deeper, the termination is more solid, thus
transferring more energy.</DIV>
<DIV>As far as the Wapin bridge configuration, and although I'm not versed
in this concept, this would be a good candidate to get this
instrument to speak.</DIV>

<DIV>A question. You said that you got more sustain after re-pinning the
bridge "with a longer profile". I take you mean that they extend higher
above the bridge surface than the originals? Of the two factors--1) new
and tight pins, and 2) higher profile--to which do you attribute the
longer sustain. There is no experimental data that I know of that speaks
to bridge pin height (there has been sporadic discussion on this list),
and I know the Wapin folks have played with bridge pin angle and
termination position with interesting results. Any thoughts? Or are there
too many variables involved here?</DIV>

List <BR>Had some time to do some experimenting with this Steinway B
which had the <BR>WD40 treatment. If you remember, the instrument was
quite decent prior to <BR>the owner spraying WD40 everywhere. Now the
tone and sustain is dead. <BR>Many of your suggestions dealt with wood
becoming soft, espeically in the <BR>bridge cap. Some suggestions
dealt with terminations be hampered. All good <BR>leads. <BR>1. I
cleaned with the termination points ( capo/ agraffe, bridge pins/bridge
<BR>cap) on 5 notes throughout the piano. <BR>Result- some clarity
improvement, but no improvement in sustain. <BR>Test - plucking the
string only ( hammers also are damaged) and listening to <BR>the sustain
and quality of tone. <BR>2. Check bridge pinning. So loose they came out
by hand with ease. <BR> Installed #8 bridge pins with longer
profile <BR>Result: Increase in sustain by 5 seconds. Tone much
fuller. Still not up to <BR>my expectations, but an improvement no less.
<BR>Some good news: the wood on the bridge cap appeared very firm
and not <BR>mushy. <BR>My hunch is that once the board is stripped,
sanded, and refinished, new <BR>bridge pins installed, new agraffes, and
capo cleaned/shaped thoroughly, the <BR>sustain will improve
dramatically. <BR>I'll keep you posted. <BR>Tom Servinsky
