Rick-
Just going through some aging email.  You probably already solved your 
knocking problem, but, just in case, I noticed that no one seemed to 
mention the source that I have most often encountered, which is: too thin, 
or excessively compressed  jack-stop felt in window.  Even if key dip is 
not excessive, the jack can/will hit the hammer flange if that felt does 
not stop its travel.
