    Yes. But keep in mind that crown is not, in and of itself, the determining factor in how a piano soundboard performs its function of converting string vibrations into (hopefully) musical sounds. ddf -- Delwin D Fandrich Piano Design & Manufacturing ...

    Del, In trying to assimilate this information, correct me if I am wrong, but it sounds like the compression-crowned soundboard is actually more likely to "cave in" under excessive load (bearing) conditions, vs. a machined-crown board. Is this a sound ...

    As is common in these discussions, apples and pomegranates get mixed up. Floor joists that are milled wet or are cut from unstable (improperly "dried") wood may well bow up as a result of further drying. However, if clear, straight grain wood ...

    I don't believe in the idea that when a rib is made straight on a saw or planer that that becomes it's natural tendency. Quite the opposite, wood wants to bow. Ask any carpenter laying a joist. "Make sure it's bowing up"! If made incorrectly and glued ...

    I didn't say they don't add stiffness to the assembly. I said they do not support load. The ribs -- again, in the original Steinway fabrication -- start out flat. When the assembly is crowned they are forced into an upward curve. Their natural tendency ...

    "the ribs don't support any load"?? As in none? then remove them, they're just in the way. If it's just to create a stress interface, then you wouldn't need ribs 1" tall. They could all be the same size too. The 2 Steinway boards I analyzed clearly ...

  • Posted in: Pianotech

    I think Terry's point is that, the way Steinway boards are built at the factory -- i.e., with straight ribs and compressed panel, the ribs do not support any load. The panel compression working against the stress interface between the bottom of the ...

    Thanks for the question. This may be quibbling over semantics, but I am not particularly fond of the word "downbearing". Slightly esoteric. First, it's really from the term "bearing stress" which is concerned with contact between two bodies.  Second, ...

    The "load on each rib"? Why would there be any load on any rib on a Steinway? Are you referring to the loading of the soundboard related to string downbearing? Again, I don't why/how there would be any load on the ribs. ------------------------------ ...

    Take a look at the sides of the fallboard.  You might find a length of brass or steel, about 1/4" wide and 3" long that is inset into a slot and secured with two or three flat head screws.  Remove screws (on both ends) and slide fallboard off. ------------------------------ ...

    Hi Tapio: I've never seen a Steinway grand, except for a square grand, that the fallboard wasn't attached to the cheek blocks. Are you sure it's a Steinway? Or perhaps somebody put a Steinway decal on another piano? A picture would help immensely. ...
