Inertia

[PSLOANE@OCVAXA.CC.OBERLIN.EDU]

 In regard to Michael's last post: When you set amhammer in motion with touch-
weights, the capstan, indeed, stays in contact with the wippen bearing and
the knuckle with the repetition lever. Therefore, the friction you mention in
your last post certainly could contribute to the deceleration you of ther
your last post certainly could contribute to the deceleration you have mea-
sured in the last half of the hammer arc travel. During a "playing" stroke of
the key (especially one mf or louder), does this contact persist after things
are set in motion. Does the inertia of the parts set in motion keep the parts
moving and nagate the friction. I suspect this is true and actually have
changed friction levels in actions insignificantly when lubricating/polish-
ing the knuckle/replever area -- i.e. when checking well designed actions
with good parts made of good material. (Friction = downweight - upweight
divided by 2).

Sorry to see you go for now, Michael. Enjoy your course!!
