    Properly done, a "lacquered" hammer is just as "voiceable" as any other types. Further, while it's become popular for many to do only "crown" needling, that is not the traditional S&S method. Those who cannot hear the difference made by shoulder needling ...

    RE: Lacquer or no?

    Posted in: Pianotech

    If you think of hammers as springs that have varying degrees of stiffness, lacquer is added to hammers to increase the stiffness of the spring.  It does that by coating the fibers and essentially increasing the diameter, by making the fiber more rigid ...

    I'd probably want to clarify a few points made here: The difference in mass of hammers mostly relates to damping effects rather than the ability to deliver energy.  A bass sized hammer in the treble will, indeed, damp too many high frequencies, a light ...

    Hi Jurgen - In my admittedly non-player perception, the impact of the returning damper lever on the overly firm keyend felt can be quite noticeable.  I'd be interested if you have something somewhat less firm than what's generally around.  If you have ...

  • Posted in: CAUT

    My feeling has always been that dense damper tray felt is prone to producing a thumping noise, as all 68 (or whatever) underlevers are struck and lifted at the same time. Key end felt/damper lift felt, on the other hand, can be a bit firmer. This helps ...

    RE: Hammer cupping

    Posted in: Pianotech

    Everyone does realize, I hope, that the reason why the hammers cupped in the first place is due the the fact that when hammers are made, felt is compressed, in a press, to create the hammer.  See my reply to the question about "Why lacquer hammers".  ...

    I agree with you, David.   I found that needling in the shoulders works some of the time on doped Steinway factory hammers.  Usually I am needling there to see if I can get more sustain if I hear it in the board itself (pluck string test).  Other times ...

    There are many factors that I cannot cover in a simple post. But I will attempt to help your thinking by pointing out that the hammer both excites the string and damps it. The exciting part is variable with velocity, as is the damping. The predominant ...
