Greg,
Here are some pics although they are guitars they are pretty self
explanatory.
Hope they are helpful

Gerry,
This may indeed help. If I can’t find a
digital photo online I’ll look through my copy of his book and make my
own photos. I appreciate your tip.

Greg,
I have often found samples in clients own homes as an example of open vs
closed
grain.
Most people have both types of oak in homes. If they have a cabinet,old
desk, shelves (furniture) etc.
most times this is an open pore (grain) finish. Oak floors and most
chairs, tables etc. would have closed pore (grain) finish.
Also keep in mind that many furniture manufacturers are using catalyzed
finishes.
Bob Flexner has written many excellent books which are pictorial references.
Hope this helps.

Does anyone have pictures (digital) of the difference between open grained
finish and closed grain finish. I’d like to email some to my customer to
show the difference. Thanks!

Right, and it also excluded damper leads, flanges, springs,
and up stop rail for similar reasons. It also excludes the
wippen, since the noise disappears with the pedal depressed,
but not with the damper lifted. What's left is what Dave
Porritt suggested as the likely cause. The key end hitting the
damper tray.

And if you remove the cheek blocks and then slide the action out a smidgen,
the noise should go away if the key is hitting the tray. If you are lucky,
this piano will have an adjustable cheekblock that will allow you to
position the action far enough out to eliminate the noise.

"The noise disappears when the sustain pedal is depressed, but still
present when the C2 damper is lifted individually."
The above tells me it is the Sustenuto tab on the damper under lever
"engaging" with the Sustenuto rod. Did you pull the action and then
lift the damper on C2?

Noise
What kind of grand piano?
It wouldn't be in the wippen. The wippen makes the same motion whether or
not the dampers are lifted.
I'm assuming you checked sostenuto tabs weren't hitting the sostenuto
bar? But that would be immediately evident when lifting the damper by
itself,
as you mention you'd done.
More info ... but then you'll probably see what it is whilst gathering
"more info." :-)

would also seem to eliminate the damper flange as the source, and I also
checked that flange and it made no unusual noise by itself. It seems that
there must be something going on within the wippen, but why the noise
disappears when the sustain pedal is depressed puzzles me. Your help
is appreciated.

Marshall,
Tabs break every now and then. Just the way it is sometimes.

Bridal straps are not difficult to hook up right? well this one was and in
the process of trying to hook it over and over and over.. the tab gave up

at the school, and I'm sure I was doing it right, just go up the right side
of the wire and around that loop and kind of under and up over the post
letting the hole on the tab through. Each time I did this the tab looked
cockide.
