Why wouldn't you want the minimum friction to occur the slowest rising rate of the key, the beginning of the stroke? The momemtum of the key will compensate for increasing friction later in the stroke. David Love www.davidlovepianos.com I think we want the minimum friction to occur at the moment of fastest motion of the key, and the rising rate produces this. If the ratio "falls off" during the last half of the stroke, it is working against acceleration of the action by the key, which means a fall-off of acceleration relative to the speed of the key. regards, Ed Foote RPT http://www.uk-piano.org/edfoote/index.html ************** A Good Credit Score is 700 or Above.
