Hi Andre....by the way thanks for your voicing book....now how about 
that bit on hanging hammers that you mentioned in the book???

Actually as I indicated in my original post, I did in fact redesign this 
action/keyboard to allow the use of  modern weight hammers with 
appropriate leverages, and it worked nicely. 

My musings on what "earlier", softer, lighter, currently unavailable 
hammers might allow this instrument to sound like was looking at the 
question from a different perspective.  "Modern" tastes in piano tone 
have optimized power as if tonal power were a holy grail.  I challenge 
this tonal assumption...actually dissatisfaction with the tonal 
assumptions inherent in modern piano tone inspired me to become a tech.  

Having listened to and been entranced with earlier tastes in piano tone, 
and also having heard a very, very few modern instruments where sustain 
and singing tone, rather than power characterized the tone, I was 
curious how this piano, which geometric evidence suggests was designed 
with a different tonal pallete in mind, would sound with an appropriate 
hammer. Alas, appropriate hammers for this leverage are no longer 
available, so my  musing continued, "what if we mess with the hammer's 
brain?"

I do wish someone with experience in the Lighthammer technique would 
chime in here.  What Andre says about the felt "excavation" producing, 
in a short time, a  less than  well rounded tone makes intuitive 
sense...but there are people messing with hammers in this way and 
reporting good results...any chimer inners?
