    Adrain....so I would need a way to test your theory.  If I understand you correctly, 88's right string, the one that sounds nice in the oxX key driven hammer test, as evidenced by the discrepancy in the carbon paper test, is still being hit, but later ...

    Maybe it was actually the leftmost string of #88 (in more firm contact with the hammer, and hence probably lower) which was precisely the culprit responsible for a quicker hammer rebound speed that allowed the rightmost string to speak louder during your ...

    It's funny how it seems that most piano technician' s shops tend to all look the same when it's time to "retire", actions and pianos and parts stacked and stored, squirreled away for that one time that "I'm going to need that"... Then it all gets thrown ...

    Wait, I read that wrong.  I meant, what if you muted o and x, holding the wedge so there's no transmission of the impact through o and x to the bridge. Would X sound then. I'm wondering is there a twist when the hammer strikes, or is X responding to the ...
