[pianotech] SnS 45 upright

[Paul McCloud]

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. Any comments appreciated.
