Bent side is just held down tightly by a molding, along with the non floating half of the tail. Molding was just nailed to the rim through the soundboard edge. It doesn't clatter of course or they wouldn't have done this at all. These are old early grands you see this on. Floating parts of the bass area are more common and some designers use this concept today. The soundboard is attached quite solidly to the rim this way... but my question is just how solidly... compared to glue ? The thought dawned on me this might have been an early attempt to allow the panel to stay more stable against the strings with respect to climate changes.... if the thought was that the panel tries to rise and fall with climate changes... this might allow for the panel to simply move out <<sideways>> along (behind) the bridge lengths instead of trying to push upwards.... but thats just musing. Cheers RicB very interesting. I never heard of such a design. No idea what the original idea was, but I argue that design could produce *clattering* sounds. I am not shure if I figure out that correctly: are you talking about wood on wood without glue or any other intermediate layer?
