>I regularly find myself having to retune the notes at the break on >any brand of piano. I have always felt that the gap for the plate >strut leaves no strings and as such, there is unstable tension there. Back when I was tuning full time, I found that Yamahas in particular were a problem at the area. On a thread regrading that many years ago, I think it was Ron O who suggested it was probably due to the difference of % breaking strain across the strut. A scaling problem basically. Also check to see if the bridge is notched to accommodate the plate strut and perhaps it is binding on one side, slipping occasionally. To remedy, a hack saw blade will ride the plate and excavate bridge material (I'm bold and use a reciprocal saw :-). -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
