<< Hello everyone,
 
 I solved a piano related noise problem that thought it might be good to be
 used as a quiz.
 
 A bit long.
 It is an Ivers & Pond Grand.
 Board shimmed, restrung, sandblasted action, hammers filed.
 I went to tune the piano today, and found a clicking noise on A5. The kind
 of click that sounds like a loose hammer head.
 -Pulled the action out, checked the hammer, it was fine. Checked the
 screws, loose, tightened them (hammer and Whippen flange). Noise was still
 there.
 -I pulled the hammer off and reglued it. Still clicking.
 -I checked the pinning for hammer flange, rep. lever, whippen flange all
 was fine. The hammer flange had been repinned (not important BTW).
 -I checked for loose jack post but ok.
 -Changed hammer assembly with neighboring one and still making the noise.
 -Checked for foreign object at the v-bar, by the string, nothing there.
 -Lift the damper way up and the clicking has not disappeared.
 -Check to see for some reason if there be anything funky with damper
 underlever, but no.
 -Checked to see if there was anything on the key itself that was loose, eg.
 leads, backchecks, maple piece for the backcheck.
 I was almost giving up umtil I looked at the action from inside the keybed
 (slight hint).
 Another hint if I would play the note quietly, it would not click.
 No other note was making that noise.
 
 Can you guess what it was?
 
 I will give the answer on Sunday. Will give more hints if need be.

Pencil, screw or some foreign object loose inside?
