[pianotech] wooden click at letoff?

[Tom Driscoll]

Jim,
 I had a click from the rosewood to shank glue joint on a part that did not 
"feel" loose at all. I pulled the knuckle (with ease as it turned out ) and 
reglued. All the others were fine. This was new Chinese and not a Renner 
part but that's my guess
