Stephen,
The knife won't work. You'll just mercilessly butcher the hammers
and that will force you beyond any doubt to replace them. These hammers
need replacement anyway so maybe you should just go ahead and try the knife
to prove to yourself that it won't work and then buy new hammers.
The reason new hammers are necessary is because of the described
depth of the groove. These will never regulate properly of you take all
that meat off the hammer surface. As Newton taught me (thanks Newton) the
distance from the hammer flange center pin to the string should be the same
as the distance to where the shank is bored into the hammer. This is
measured from the center of the shank to the tip of the hammer. If you sand
away this much material those measurements will never match and you will
have regulation problems.
I suggest you get together with your neighborhood tech and
purchase a set of pre-bored supply house hammers and glue them on yourself
with a little guidance from the tech. This will get you back to a usable
piano with a little experience under your belt and a better taste for
whether or not this is what you want to pursue. Make sense? Hope this helps.
