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. dp David M.

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. Bob Hull
