After repairs, this thing showed up. What happened? If the action is at a different height than it was originally, neither the string grooves in the hammers, nor the dampers would mate with the strings. That wasn't reported to be the case, so the action height probably didn't change (much) with the repair. If the action height didn't change, then either the keybed height didn't change either, or the action supports (ball bolts, or whatever???) were screwed up to reposition the action after the repair left the keybed too low. If the action is in the right place relative to the strings, then it just about has to be the key frame that's not at the right height. If the ball bolts were adjusted, that would account for it, or if the key frame was removed to make the repairs, and whatever shims that were under the key frame were possibly not included in the reassembly - that would account for it too. Since the key frame, cheek blocks, name board, and key slip all index off of the keybed, some trial fitting needs to me done to see if there is enough clearance between the key and the name board to shim both the back rail and center rail of the key frame up enough to let the capstans reach the wippens. If the key hits the whoositz, it ain't gonna work, and it gets a whole lot more expensive to fix. The trick in this case is guessing right as to what the heck actually happened that accounts for the condition the piano is currently in, and correcting the problem that's causing the problem instead of introducing more problems by modifying what wasn't really the problem in the first place, in the attempt. So if the keybed is in about the right place (a good chance, in my estimation, since there aren't too many ways to get it at the wrong height during a repair), then the key frame is the likely culprit. The back and center rails can be shimmed up leaving the front key height where it was, or wherever it's needed. It's further back where the key needs to clear the name board felt that needs the attention. Or I may be entirely mistaken and it's something else altogether. Ron N
