I wonder if each of those two dimensions were allowed to pass at the factory because they were each within tolerance, though the latitude allowed was too much to accomodate their combination. I see this as a constant example in the Steinway damper actions from about piano # 360,000 on up to 475,000. Perhaps there was no one there to catch those cases where two tolerances were allowed their maximum variance in opposite directions and the result is an action that has no "sweet spot". You can't lower the strings, so raising the stack, (or entire action) is the alternative, but is there some reason why the action is so low?
