[pianotech] Hammer Line Issue

[Barbara Richmond]

Oops, I didn't read carefully. Duh.  



OK, what's the keydip (& key height--bet that piano hasn't had its keys leveled in a while), hammer blow and all the other pertinent specifications? 



Still wondering about those hammers that were sitting up off the rail...

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.
