Wim, Not only will I not blast you for using the stuff, I will say that if
you work on Steinway hammers at all, you must use some kind of hardener.
Ronsens too. They are designed that way. I like working with these hammers.
You can get beautiful tone with them. Takes work. As do any other hammers.
Different technique, same result.

  Melting Plastic, SOT, (Slightly Off Topic.)

  For hammer juice, I use acetone and keytops. I keep this solution in a
plastic bottle.

  I'm no chemist, so how come the acetone dissolves the plastic keytops, but
doesn't  dissolve the plastic bottle in which it is kept?

  PS. Before I get blasted for using this stuff in the first place. please
be assured I use it very sparingly only on Steinway hammers when I voice.
These Steinway hammers are first given a liberal dose of lacquer and lacquer
thinner, as per factory specification. I don't use any kind of juice on
other hammers. (I keep the lacquer mixture in a plastic bottle too, (a
mustard bottle), and it doesn't dissolve either.)
