[pianotech] wooden click at letoff?

[Mark Purney]

I've had clicks like this that turned out to be the glue joint between 
the hammer and shank, even though it didn't seem loose. But the knuckle 
glue joint seems more likely here.

Obviously, checking that the flange is tight to the rail is one of the 
first things you do in troubleshooting a click like this, but I've had a 
very strange thing happen on 2 or 3 occasions: Tightening the screw 
didn't make the click go away, but loosening the screw (enough to 
separate the flange from the rail), and then re-tightening the screw 
fixed the noise. I don't know why this would work, but I now do this 
whenever I'm stumped on a clicking sound, just in case it happens again.
