Is it safe to assume the piano has been strung for a while and has stabilized somewhere near standard pitch? I would recommend tapping some hardwood shims into the gaps between the plate flange and pinblock and see if that helps - if suddenly it becomes stable, then I guess the answer is obvious. At least it won't hurt anything. Terry Farrell ----- Original Message ----- > Whatıs the latest on whether or not a pinblock should butt against the > plate > flange?
