 List,
 
Action clicks have been costing me  time of late.  I had yet another click today.  The piano is a Kawai K-30 upright.  
 
On hammer blow, there's a click, as well as some resistance late in the key stroke.  This was happening on many notes in the middle section of the piano.  I thought I'd cured the problem at my last visit when I regulated the backchecks to catch the hammers sooner.  I found more clicking today, though.  I was determined to find the cause rather than to try to treat the symptoms. 
 
What it isn't: 
 
jack hanging up or hitting anything it isn't supposed to
loose hammer head or shank
loose catcher or shank
loose anything
 
Some of you long-time techs should get this one in a hurry.  It was a new one on me, though.
