  • 1.  soften over-lacquered hammers?

    I am servicing a Steinway D that has hammers that are hard as rocks. Even the
    crown of the hammer has been lacquered. Does anyone have any suggestions for
    softening these rocks? Someone suggested a few drops of lacquer thinner on
    the crown. Has anyone had any success with this.
    
    Thanks,

    I've had very good success with 1 part of "Snuggle" fabric softener and
    7 parts of isopropyl alchohol.  Put it on the striking surface so it
    covers 11:00 to 1:00.  Dry them with a hair dryer and give it a try.
    It really does a great job of softening the hammer and it lasts a long
    time.
    
    Let us know how you did.

    Might I humbly suggest that... "If you have to ask how much, you probably
    can't afford it."  My recently completed divorce showed me approximately
    _how_ much, however.
    
    Them soft legs carries some hard prices.

         It was the nature of recording technology here in Nashville that
    required, (or so say the "old-line" engineers), really bright pianos.  By the
    time digital equipment, and better microphones came in, there were a number
    of pianos that were way over the top!
          Many  were not salvageable, but in an attempt to restore SOME kind of
    tonal range, I tried acetone on the hammers,  and I am not talking about a
    few drops,  more like a teaspoon, right on the top.  I think that as the
    solvent migrated through the felt, it carried some of the laquer away from
    the strike point,  but it was still a compromised hammer.
        Perhaps the use of pliars may help; since you are really in a nose dive,
    try anything!!
    My advice is to try these remedies,  but be ready to replace the set.  (BTW<
     was this laquering done to get at least some sound out of a dead
    soundboard>?)
    
    Good luck, you will need it!

    A few drops?  Just soak 'em with thinner, allow to dry a few weeks, and
    start over. If they are really bad, you can wash them out with a lot
    of thinner, let dry a month, and then built the tone back up from
    nothing. This is presuming that they are not ready for replacement
    otherwise, and you want or need to save that expense.

    Actually, there have been a couple of price increases since then. Current
    price is $169.00.  I have been considering a Swiss made model from a local
    machine tool supplier for about $145.00, but the only reason I didn't get
    yet is because I know that as soon as I do the new, probably cheaper
    digital models will be released.

    Have you tried the steam voicing as discussed here several months ago.  I
    have used it successfully on hammers overhardened with keytop material
    dissolved in acetone, though I haven't tried it myself on lacquered hammers.

    Why should the resin make any difference? What each material does to hammer
    felt is essentailly the same: coat the fibers, glue fibers together where in
    close proximity, and hopefully not fill the airspace in between the fibers.

    Paul,
    
    Sorry so late on this, but I knew this appointment was coming up.  I did a
    full regulation yesterday on a customer's S&S L with very hard, laquered
    hammers.  After reshaping and regulating and getting everything feeling
    right, the hammers were still as hard as rock - we're talking Horowitz
    bright.  After needling for about 10 minutes, I went to the car and grabbed
    the steam pot.  Just a scant 11/2 seconds on each hammer was all that was
    needed to bring those hammers down DRASTICALLY.  So, to answer your question-
    in this case at least- Yes, it does work on laquered hammers.
