soundboard buzz

[A440A@aol.com]

My first try was going to be to drill out the dowels in the ribs and replace 
without taking the bridge off.  It really sounds like the buzz is coming from 
this one rib/bridge "foot".

Any takers?

The first thing I would do would be to drill a 1/16" hole down from the top 
of the bridge into the dowels.  You can locate them by the small dimple on the 
bridge cap.  drill far enough so that you know you are into the top of the 
dowel  (3/4" is usually enough).  Using a pre-heated syringe, squirt a very thin 
mixture of hot hide glue down into the hole and then drive a blunted toothpick 
in on top of it.  
    I have stopped a few mysterious buzzes this way, and if you need to 
dismantle stuff later, it doesn't get in the way.  A sharp chisel and a touch of 
graphite stick and the repair disappears. 
good luck,
