Reminds me of my first adventure into piano technology (before I got into the business). My brand new S&S 1098 with a full quarter-inch of reverse crown - stretch a string across the back of the panel parallel to ribs, let string touch panel in center and observe both ends a quarter inch off the panel. I wish I remember whether I had taken any string bearing measurements - however I seriously doubt it - would have been interesting though. Dog-gone hard to imagine exactly what might have caused such a condition. Terry Farrell > I have a 1990 Baldwin 6000 (52” upright) with an inverted > soundboard.
