I was in the process of regulating backchecks and noted that the backcheck wire was loose in the key, so I fixed that with thin CA glue. The rattle persisted and seemed to be coming from the top action, so I pulled the wippen. There was no rattle in the key, the capstan was tight, and everything appeared tight in the wippen, even when banging it on the table. What was causing the noise? Bill Maxim Hard punching on the jack regulating button ,or loose spoon contacting the aforementioned button? Also on a smaller Chickering I had a loose screw mounting the damper action. This was a machine screw with a washer and was more of a metallic sound than what you describe and vibrated on only one note. Took me hours to find!
