  It sounds like you've got a grip on it. 
   I will say though initial filing of  hammers create a  better sound when  
pointed up to a nicely  defined strike point. The  the tone will improve & 
focus better if this  is done. If this has been done Then go to  string mating 
then to   fine paper( 320) & ironing . If you still need  a bit more attack then 
 Try some 10 to 1 lacquer &  acetone right on top of the hammer  to  balance 
the harmonic structure .  Use only 4 to 6 drops & call it  good. I call this 
break in fluid. So muich of the sound we associate with  attack is caused by 
the very top 1 mm or so of felt right on top of the hammer  so there is no need 
witht he Ronsen hammer in most case to hose it down with  solutions.

Dale,
I didn't have time Friday to finish assessing the  problem.  I'll be looking 
at hammer-string mating (string levelling  etc.), terminations, bridge pin 
seating (bridges weren't replaced),  dampers (overextended felt possible but 
didn't look like it) etc.  I  presumed cupping because several middle 
unisons are different then the  outside unisons.  Again, other possible 
issues have to be eliminated  before going to hammer voicing.  There is very 
good sustain in the  high treble.  I'm caught between tuning the attack 
phase or tuning  the sustain because it is so long.
By the way, the hanging job looks great,  better alignment and travel then 
I've seen on some makes.  Regulation  much better than I've seen from some 
stores.  The case is exquisite  minus a gash thanks to the delivery 
guy.  The plate is beautifully  detailed etc.  Decal on the soundboard looks 
original.  Neat  coils on the stringing job and so on.  The customer and I 
are very  happy.
The grunt work is done and now I'm busy dialing the piano in.   Can buy that 
too, I understand, but I've got to justify markup to myself.  ;-)
Andrew
