    Roger, if you do not believe what I am posting, that is fine, to each his own. However, your questions are so generalized and lacking in specificity that I have no interest in answering them. However, if you can be targeted in a question that concerns ...

    The tiny Hertzian contact references what is called the contact patch, which is the surface area of contact between two cylinders. For us that would be the cylindrical string contacting the cylindrical pin. The famous physicist Heinrich Herz did considerable ...

    Glue Containers

    Hi all, What's your favorite way to transport glue for field work? I buy Titebond Quick & Thick in large bottles and used to transfer it to a mini GluBot. While I love the GluBot in the shop, the cap pops off too easily inside my tool case. I'm currently ...

    Don, I'm not wanting to evaluate repetition by limiting key travel, just to observe, because key travel will vary in the natural course of playing. It can also happens very much by choice, when trying to get a very delicate sound. I find that using a ...

    Fred, Yes, it's a good point - the Kawai videos I had showing high speed repetition were all full keystroke repetition. That is the condition where the hammer definitely is stopped by the backcheck each time it is played. If one plays very ...

    The cause is simple. The sound from the piano bounces off the fan blades, causing periodic differences in the sound returning to your ear. That's obvious. It often happens with air conditioning, as well. I just ask my customers to turn it off, but in ...

    Is there a circular thing in the s curve of the piano? Those larger Hamburgers usually have a lock to prevent the opening of the large lid. If it has the circular thing, spin it, one way or the other and it will let go of the lid.
