Just when I think I know what I'm doing, something small humbles me.   In 
this case, it was the damper on the tenor of the bass-tenor  break.  The funny 
shaped one.  It's a new Kawai grand, and the  customer complained of a b3 that 
wouldn't stop sounding after being struck  lightly.  Sure enough, the tricord 
finger closest to the plate wouldn't  seat in because the other finger wouldn't 
go down far anough between the  strings.  
 
I looked for tight flange and guide rail hole, but those things were  fine.
 
I tried string spacing, but since there are agraffes, the effect was  
minimal. 
 
I did some wire bending, and that helped a little.
 
I did some very minor trimming of the damper to shape it so both  fingers 
could rest equally on/between the strings.
 
In the end, it worked fine.  Better, in fact, than the damper on the  A# 
bicord on the other side of the break...:-)  But it looks tilted, and  not spaced 
quite like the other dampers.  
 
My thoughts are:  
 
I could have trimmed more of the felt.
 
I could learn to bend wires more effectively.
 
When I look closely at most pianos, few have the funny-shaped dampers  near 
the plate seat and lift the same as their neighbors. How good  should I 
reasonably expect to get it to look and play?  
 
Damped enthuiasm in CA,
