Ron, Also...I think it is a real disservice to technicians, especially new ones, to express your phobia (I can't think of what else it can be?). From your own words, "the notch edge has been crushed by the bridge expanding with humidity increase"....how is it you can decide that the crushed notches and bridge caps you see are from people seating the strings? So your response to my post about tapping is "get the biggest hammer you can lift, and seat those strings as energetically as you possibly can. Use both hands. Drive them in really deep, and rest assured in the belief that you have rendered a miracle and corrected a situation that isn't demonstrably physically possible in the first place."???? Go ahead, Ron, recap that brand new piano, because that's where the problem is...while your at it redesign soundboard...but wait! Why do that...it isn't going to last...
