Patrick, I would try tapping the pins down about 1mm and see if that helps. For older Kawai's and Yamaha's This can bring 40 inch/lbs to 60 to 90.

Hi, I have a couple clients with recent (past the 5 year warranty, less than 10 years old) Boston and Essex grands. A few tuning pins have less-than-borderline torque, particularly in this cold-dry New England winter. I have a call back on the Essex ("This one note sounds horrible!!") which I tuned back in November. My options are drive pins (I'm visioning coils smashed to the plate, not a good choice), use CA (my usual choice when dealing with decades old pianos), or install a few oversize pins. Anyone know what length and diameter is the standard on these models (Boston GP-163 II and Essex EGP161)? I recall reading that Kawai and maybe Yamaha sometimes use a pin larger than 1/0 but less than 2/0. Thanks, Patrick -------------- next part -------------- An HTML attachment was scrubbed...
