Loose lower rail (where the sticker- tongue-flange screws on) `Tom Driscoll -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of Farrell Sent: Wednesday, March 19, 2003 7:45 PM To: pianotech@ptg.org Subject: Tonight's Puzzler Worked on an old upright (Adam Schaff - Chicago) tonight - better condition than most - 88 functioning keys, but still, 90 years worth of wear. While giving many of the keys firm blows while tuning I noticed a reverberation in the keys (maybe 25%-50% of them - some more than others) - a bobbling-like feel at the end of the keystroke. You would not feel anything abnormal on a light to medium blow. But on a hard blow it felt like something was dancing on the back end of the key at the end of the key stroke. It took me a little while to figure it out. It was not the first (or second) thing I checked for. What was it?
