A crack or small separation will buzz, but not rattle. A large separation will rattle, but it would be obvious. The way you described it, this almost has to be something hidden on the board, like a coin or marble or something heavy like that. Use a strong light and a dentist's mirror and look at the ENTIRE soundboard. Don't stop looking until you are sure you have inspected every square millimeter of the board. You will find something. Be sure to look under the bridge loop (between bass and treble bridge section) and under the bridge cutouts (if any - I haven't seen a B in a while) for a coin. They are very hard to see. Don Mannino RPT ---------- From: A440A@aol.com Sent: Thursday, September 11, 1997 8:58 AM To: pianotech@ptg.org Subject: Foote Rattlers Greetings all, Ummm , HELP!! I have run into a soundboard rattle that I cannot squelch. It is a Steinway B, (Hamburg). and there is a buzz on all the bass notes. It is presently in a very high-dollar recording studio, so it absolutely has to be fixed. Here is what I know about it; Light pressure on the board, under the cut-outs around the bend between bass and treble areas will stop it, but wedging a small wedge between the board and bridge here will not. From under the piano, I can lightly tug on the lowest three ribs and hear a scrunch,scrunch sound which sounds like splintered wood. When doing this, the sound seems to come directly from the bridge. There are not visible cracks or repairs on the board or bridge in this area, and the buzz seems to be somewhat humidity dependant. So, shall I drill small holes from underneath, into the bottom of the bridge assembly, then fill with glue and hammer in shoe-plugs hoping to force glue into any opening inside this area? This is what I may try, assuming that there is a separation in the board, under the bridge. The edges of the board are tight, and there is no discernible separation between ribs and boards. The dowels all appear to be tight. Ideas, anyone? Thanks, Ed Foote Precision Piano Works Nashville, Tn. ---------------------- multipart/mixed attachment A non-text attachment was scrubbed...
