Wim, Do you mean to insert the eye bolt HORIZONTALLY into the rib, then, and align the hole so that the screw then is inserted through it and is screwed upward into the sound board from the bottom? Doesn't this assume a lot of drawing power of a small wood screw into a thin piece of spruce? Does this leave a screw tip showing through the soundboard from above? Or would you use a machine screw and washers/nuts to spread the load? Geoff, Are you thinking of putting the T-nut VERTICALLY through the rib and then screwing a machine screw into it down from above? This might be another option (and worth exploring!), but I don't think it's what he meant. We'll see when he answers the query above. Interesting thread! John Dorr, RPT Helena, MT Sender: "Geoff Sykes" <thetuner at ivories52.com> Don't you mean something like a T-nut? That actually makes a lot of sense. Thanks. -- Geoff Geoff Sykes, RPT Geoff As David explained, the buzzing is the vibrations between the soundboard and the ribs. One way to "fix" this, is to pull the soundboard to the ribs with the use of an screw through an eye bolt. (the kind you put a hook through on a screen door, only very small). Attach the eye screw into the rib, and screw a small screw into the soundboard, through the eye. It will draw the soundboard to the rib. To make it more permanent, squeeze a little glue between the soundboard and the rib. You can do this from under near, laying on your back, but it will be easier if you tip the piano on it's side. This is certainly not a perfect solution to the problem, and you might not be able to get to all the cracks/ribs, but it might eliminate enough of the buzzing to get you by for a couple of more years. .
