QUERY: hammer/string interaction

[Paul]

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.
