Would this work -- Locate the points where you want the weights and drill a small, appropriately sized hole down through the bridge and out the bottom of the soundboard. This hole will be approximately 1/8" in diameter (I don't remember the exact size but the hole is sized to fit the socket set screw you're going to use). Then run a socket set screw -- say, about a #10-24 by about 1 1/2" or 2" -- down from the top of the bridge until it extends out from the bottom of the board by about 1/2" or so. Drill and tap your brass weight accordingly and screw it on. I make my weights out of hex brass stock. You can usually reach in and screw them on tight with an open end wrench. Del
