<< I've had to reglue a few dampers including one after their practice so I'm suspecting the hammer-shank glue joint. Would this be a candidate for a little vinegar to reactivate the glue and tighten the joint? Or would it be preferable to simply remove the worst hammers, knurl the shank and re-glue? >> Greetings, I don't think vinegar is as good a treatment as thin CA,(vinegar only works well on hide glue joints), but if there is time, simply taking the hammer off and wiping a small smear of Tite-bond or Bolduc's glue on the joint and then spinning the hammer back on has always given me a permanent fix. Take care to protect the pinning, ( I like to take the shank off before removing the hammer). Before tearing things apart, though, it is easy enough to swap the suspect hammer and shank with a silent neighbor and see if that is, in fact, where the noise is coming from. Don't forget the knuckle! I have had several clicks that were coming from loose core/shank joint. Don't forget the top post on the underlever, ditto. I have had clicks coming from loose underlever leads, too. They can feel tight if you press them firmly in testing, but using the lightest touch, they often will give, just a little. A paper towel underneath to protect the keybed, and a drop of thin CA on the edge of the lead always seems to alleviate the click. If there are clicks in the three-lead underlevers, you will have a more difficult time getting the CA on the back ones without making a real mess, (you can tell if you have glued the underlever to the tray when those notes seem a little heavier to play...).
