Tuning Trouble

[Dave Doremus]

I have a problem piano in a hotel bar that will NOT stay in tune in the
top two treble sections. I have tried everything I can think of to
stabilize it, it has improved but there are still a few notes that slip
consistently. Even when I pull them way sharp and pound them down to where
I want them I can still knock them flat with a few heavy test blows.
Admittedly, I think they would stay under normal usage but this poor B
gets three sets a night by very heavy players, one string a weekend
average breakage. I have seated and tightened coils, tapped strings, filed
hammers, tightened plate screws etc. Block is original and a good fit,
piano was restrung in a sloppy manner two years ago, not by me, and had
lots of regulaion and touchweight problems when I first saw it. Now all is
well and everybody happy except for the stability. I'm open for any and
all advice no matter how weird. Thanks all.
