If there was good crown and bearing, what was your criteria for determination that the piano should have gotten a new board? Was there indeed measurable positive crown in the area where the distortion was, rather than in some other part of the board, and was the distortion there before the strings were replaced? Was there positive bearing on both the front and back notch of those notes, or just overall positive bearing speaking segment to duplex? This isn't one of those mystical soundboard things that just happens and nobody understands why. There is a reason for it. How about some specifics? There is also a conceptual problem here that is nearly universal among us piano tech types. Installing a needed soundboard is not spending extra money. Not installing a needed soundboard is not doing all of the required job to cut costs. I know, that doesn't make the problems go away when the customer won't spend the money, but I thought it was time that was said. Would springs help? I have no idea. I've never tried it. Ron N
