    From our previous posts on piano humidifying systems, many here know that I consider the use of de-humidifying systems as appropriate. And that I have never encouraged the use of piano-specific humidifying systems, nor have I ever installed one. After ...

    Paul, with the threads getting a good start to halfway-in, I would think you would consider using a 1/4" x 36 (or 7/32" X 36) tap to enable the agraffe to go in the rest of the way. Bring the appropriate drill bit along, just in case, but it doesn't ...

    This is a C171 Hamilton. I don't think it's a Samick, as there are no SG numbers on the action frame. Daewoo? Not Young Chang either. I had some agraffes that looked the same as the original (arched top, not straight), and the threads seemed to work ...

    Hi Geoff, Did you ever get your question answered? I have the same issue currently on-going with an Aeolian I just purchased. I have what appears to be a 1981-1985, Aeolian upright (AU-48), full-sized cabinet, near-flawless ultra glossy white, with ...

    Yes it's an "old idea" that eventually faded away (partially due to logistics). I remember Bob Russell Senior offering me the same "deal" at a Cleveland Ohio conference (including a follow-up phone call a few weeks later)! That was in 1978, a year after ...

    Warning; Long winded post. Thanks all for the replies. It took some digging but I finally found the factory specs for stack height. So as it turns out the magic number was 4 1/4" after all for a model B and 4 1/2" for a model D. To make things ...

    Kind of hard to read, but most of the factory specs are here. Model B string height should also be 7 1/2", and model C should be 7 5/8" like the D. Standard bore distance is increased to 1 15/16" on C's & D's to match the higher string heights. If ...

  • Posted in: Pianotech

    Hi Wim, The cavity opening is immaterial providing it isn't too short for drop screw clearance. What matters is the dimension from the keybed to the string plane. On a D the dimension should be 7-5/8" (194 mm) at around note 62. RE trouble fine ...

    Thanks Mr Gravagne, The string heights are around 192mm. A little higher in the mid-range and down to 190 at note 88. The stack is already a little too high from the factory (1967) as evidenced by a few notches from drop screws at the bottom of the ...

  • Posted in: Pianotech

    Hi Karl, This issue is not too common, but it does come up regularly. For starters, we need to know the string height from the keybed. The S&S spec for models up to the B is 7.5" (190.5 mm) plus or minus a small bit from the keybed to the underside ...
