I have had good luck in stabilizing the buzz, by using course thread gyprok screws. Bore a hole through the rib, on each side of the crack, so that the screw is free. Run glue, behind the rib. Then insert the screws, which have an aggressive thread, they grab the soundboard, and pull it snug, against the rib. On your next trip, to make it look nice, remove the screw, and drill and replace with a piece of dowel stock. John M.
