[CAUT] Kawai GS60 Bore distance

[Porritt, David]

Bob:

When the board gets in this shape the best thing I've found is the riblets that Darrell Fandrich makes.  We have a B here that was helped quite a bit by one and we had a D on which I put 2 that really helped.  They're inexpensive, reasonably easy to install and reversible if need be.

1.  I'm putting a new set of hammers on a Kawai grand.  I'm measuring 130 mm on hammer bore distance for this Kawai GS60 - does this match their specs?

2.  Typically, how strong are Kawai soundboards?  Aren't they CC?  I'm hoping these new hammers will help sustain return somewhat - I have tried voicing and shaping to practically no avail.  These have already been shaped a couple of times at least anyway so they're getting down there.  It's had about 13 years of very heavy usage.
 I will measure downbearing later today.  Mainly from about Bb 4 up through octave 5, maybe some of 6 are lacking in sustain quite a bit.
