     Too All
     The pictures show a added cut off bar I posted about last week 
which was recycled from the baldwin upright. I decided to add the fish 
in the treble after Terry posted his pictures & alos because of input 
from many other rebuilders on list that have discussed more modern 
approaches to developing sustain & power in conjunction with sound 
board crown longevity.
  As posted previously the ribs on this piano are extremely long & 
would have provided inadequate crown support. Also the ribs & 
soundboard area in the top treble were extremely generous to the point 
of sacrificing stiffness required for adequate impedance. I'm changing 
all the tri-chords top bichords & probaly a bass bridge change too.
  The jury's still out tonally. I'll report back when its strung. The 
action is already to go so in march I'll tell "The rest of the story" 
We pressed the board today, the block is made  as seen in picture.
