John Roger Weisensteiner(spelling) showed us a video/film of what happens to an action during playing taken with high speed photography. We were attending a Kimball factory class at the time (mid 1980's). He may know the where abouts of those films. Very impressive to see the amount of flexing and distortion the action parts go through-both vertical and grand-during "normal" playing.
