[pianotech] SnS 45 upright

[Floyd Gadd]

I own one of these pianos.  The last time I tuned the top two octaves, I got the strings close, then fine tuned by slightly springing the pins (no rotation) with the hammer in line with the strings.  It seemed to work, but I need to go back to it and see what the implications were for stability.  (This piano is in my restoration queue, and I'm storing it off site right now.)

Hi, Limhseng: These pianos don't have pin bushings, so the tuning pins will bend easily, especially if they are tight. If you put your tuning hammer in the same line as the strings, the pin bending won't affect the pitch very much. On an upright, that means keeping the hammer almost vertical. If you lubricate the bearing points, as someone suggested, you'll make the situation worse, since part of the problem is that there is too little friction over the bearings. Every little movement of the pin will affect the pitch. You must be able to move the tuning pins in very small increments. Most pianos are hard to tune in the high treble, and especially these Ste.'s with their design, they are very hard to tune accurately. Good luck.

Octaves and unisons were difficult to set and stay stable. Pins are good and the piano condition is still very good.
