The Beauty of the Open-Faced Pinblock

[Delwin D Fandrich]

It's called a soundboard cutoff bar. (There are other names, but that is the one
I use). It is not located in the bass section, it is located in the front left
corner of the soundboard area. The bass section is toward the back of the piano
in the area around the bass bridge. 
 
The cutoff bar, along with the filler block (which I call the "fish" due to its
shape) used along the inner rim up in the treble area, limit the size of the
soundboard, making it more function somewhat more efficiently.
 
Much has been written about these soundboard shaping devices on Pianotech. You
might check the archives. As well, I've been discussing them and illustrating
them in my classes and seminars for some thirty years now. I realize these are
generally presented some distance from your home, still, if you find yourself in
an area where one is being presented you might find it worthwhile.

Hey Now,
 
I have a question about the picture of the sound board that is attached to the
original post. Why is there a cutout in the bass section? I believe Terry
Farrell posted some pictures of a sound board he had made with a similar shape a
while back. Can someone please explain the unusual shape.
 
Inquiring minds would like to know if its not too much trouble.

Well, now you make me wonder. I have all of the photographs of this piano
labeled "Bosendorfer" but I could be wrong. I did this piano some fifteen years
ago.
 
I don't have a picture of the finished piano but I've attached one with the
soundboard being glued in so you can see the shape. As I recall the piano was
pre-1880s. I could probably find the build date with some searching.

Hi Del!
 
What kind of Boesendorfer is that, sicne it doesn't have a capo d'astro? I have
never seen one without before.

Yes, aren't they, though. From an older Bosendorfer we did some time back --
 
See the attached.
