Since we haven't totally left Steinway dampers yet, I have a question
regarding damper stop rail regulation.  It seems that if you regulate the
stop rail according to damper height with the pedal, you have dampers
jumping up and down on the keys with a hard blow.  If you regulate the stop
rail according to lift with the key, then when the pedal is activated, the
key jams the damper lever up into the stop rail.  Have ya'll experienced
this, and if so, what is the solution?  I seem to remember an article some
time back by Bill Spurlock about the compound leverage caused by the damper
flanges being attached to the lifter tray - I'm assuming this is related to
the problem I'm having.  Thanks.
