First, were there any grooves to speak of? Did the mettalic sound change with the shift?
Sounds like you are on the right track, but with Steinway hams having laquer in them, many times the "traditional" approaches may not yield the best results.
Big question: are you familiar with the David Stanwood technique of using a compas needle chucked in a pin vise, followed by striking the surface with a tiny (like 1.5 oz) ball pein hammer? The compass needle does not penetrate deeply but really "rearranges" the packed down felt fibers just below the surface. Then the ball pein sort of "packs down" the suface and kind of rounds out the sound.
I have had tremendous success with this on quite a few occasions (and many of them very critical performance venues! It is definitely something to have in your bag! Then acetone or similar may be the next step.......Kevin

Subject: Voicing Out Metallic Noise
Hello all,
Any suggestions / advice about voicing out metallic noise out of hammers?
My subject in question is a Steinway M, original hammers (or at least Steinway hammers). The owner called complaining about a metallic noise for about an octave around middle C. I tried to break up the hard spots in the hammers (there were various hard pouches, both sides), but wasn't overly pleased with the results. The metallic sound was much less noticeable, and maybe the owner forgot about it shortly afterwards - I haven't heard back since....
Any suggestions on dealing with this in the future (for S & S hammers and 'normal' hammers)? And maybe a faster method (it took about an hour to do)....
Thanks,
