>Many pianos with cutoff bars have an open space, or a different species of >[filler] wood outside the cutoff. Is there a way to gain the acoustical >advantage of a cutoff bar, but have it appear traditional on the top side? Sure, just fit the panel to the available space as if there was no cutoff bar in place. >For instance, could the ribs be notched and continued on to the rim, just >to support this area?

Who says the ribs have to be continuous through the cutoff bar? And if they were, how do you crown the rib on one side of the bar, and leave it flat on the other? You terminate the ribs in the cutoff just like you do in the rim, and make separate short flat ribs for the bass corner. Simple is good when you can get it. >Is the cutoff bar affixed to the beams? Yes. Glued & doweled. >In one picture it appears to pass over the metal termination plate for the >beams. Is this a problem? Not so far. >It appears to be the approximate cross section of a bridge.
