Interesting trip?  I don't think this all that new. I've seen Baldwin L grands with the same deal. It might be a Del Fandrich idea but I'm not speaking for him of course.  Actually when you think about it that little piece of thin rib that goes into the liner is only a small part of the equation as far as the strentgh needed to hold the board on the rim. The glue is doing 95% of .the work. Radio speaker thing and labor saving method. No fitting notches to the rib and the board can float a bit during installation hhm not good.            Dale <BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px"> Hi Dale, This is another one of those "please explain" threads with no proven answers. Whilst I was in China I went to a City called Yenti ?. there was a piano manufacturer there that was making upright pianos based on the Kawai piano. Now these pianos had soundboards with tapered ribs but,  the ribs ended about 1" before the rim and was terminated by a screw through the soundboard, rib and into a holding block of wood. This meant that the board was fixed at its outer edge only by the board itself. To me this is getting into the radio speaker method with a freer edge to allow the board to be more sympathetic to the strings vibrations. All my work in China was done through interpreters so I may have some miss information but I saw the soundboard with my own eyes. Regards Tony </BLOCKQUOTE> </HTML>
