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.
