Here's Matthew's first post:

>I went to tune a clients piano today.  It is a Kawai Console, year 1986.
 
>The very first thing I noticed was the hammer line was totally screwed up.  Some of the hammers were resting on the rail, and others were off the >rail.  I unscrewed the action bracket nuts and pulled the action back a little until all the hammers were resting on the rail. "

What is the likelihood that the piano had overly strong damper flanges, un-noticed for 22 years ?  The customer didn't complain of bobbling hammers. That problem occurred after Matthew adjusted the capstans and let-off. We are into the second or third stage of treatment without diagnosis.
