Quiz

[Victor Belanger]

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.
