Today's Puzzler--answer

[Bill Maxim]

Lisa,

You were very perceptive.  It rattled before I took the wippen out.  Every
time the key was played, there was this slightly metallic sound as though
something was bouncing around a bit, that I would call more a rattle than a
click.

With the wippen out, there was no sound of anything loose when I slapped the
unit around.

Then when (with the wippen out) I would move the jack through its range of
motion, there was this "click" as the jack tip hit the stop felt, and again
as the jack returned to rest.  I have no idea why it would rattle in one
situation and click in the other.

When you said, "I've had to glue-size the threaded hole in the jack before
because of a click there...it had also
 unadjusted itself," you hit the answer.  With the jack at rest, the loose
threaded hole was under tension from the spring and would not rattle or
click.    In motion, it made the noise.  Fixed with thin CA glue.

Bill Maxim, RPT
