Let's come right out and say it, it looks sexy!!  But I guess that means we
pianotechs have a low threshold for stimulation doesn't it?

Hi Will -  Comments below:

 

A couple of questions, though:  First, I noticed at the top of the board,
treble end and just below the pinblock, is a narrow strip of wood that
flares out about 1/3 of the way down from the treble end.  Likewise, you
have two strips of wood just above the tenor end of the bass bride curving
to match the shape of the Z- bar.  What is the purpose of these?

 

Here is my guess:  In those areas you have poor access to clamp the panel to
the liner and z-bar, so these are there to serve as clamps along  with
screws when gluing in the panel.  Is that correct, or am I out to lunch,
like the dog shown below?

 

Yeah, I think that is pretty much correct. Ultimately, it was because Del
told to me do it that way! But it sure did make sense. Up the the treble
area, we really chiseled out as much of the rim as we dared - to make the
soundboard between the bridge and the rim (under the speaking area of the
strings) as wide as possible. The piece of hard maple there makes clamping
easier and also adds a little bit of insurance down the line I suppose. The
pieces that screw into the Z-Bar, yes, provide clamping pressure where it
would be difficult to apply pressure - one could use go-bars, but keep in
mind that the Z-Bar is rather flexible down at the tenor/bass end - the
screwed-in-maple pieces work very well for clamping. I guess I could have
removed them, but they don't interfere with the plate, so I left them in
place.
