Many thanks to all who responded. Paul, I did bow out, but for my own education, for "next time", I would like to learn more about how to regulate these animals. Joe, you say "if the dampers lift at less than 1/2 the key stroke, then the tabs will not be "forced" by the sostenuto bar". But it seems to me that as long as all the dampers lift at the same point, it shouldn't matter whether it's 1/2, or 1/3, or 2/3 keystroke. I would want the sostenuto bar to lift the dampers beyond the point of initial contact, to get out of the way of the other notes dampers, but because of the way the sharpened ends of the metal wires contacted the rubber bar, I was afraid they would chew through the rubber, so it's currently set up such that the bar only holds the dampers at the height that the keys lift them. Dave, Jon, and Julia, thanks for mentioning the manufacturer's models that actually work - I hope I run into one soon so I can check out how they do it. Mike Michael Spalding spalding48@earthlink.net
