<HTML>There are obviously several ways to clamp a bridge to = a new soundboard while gluing - pneumatic press, go-bars, screws with their = holes later filled with dowels. Suppose one is using screws. I have heard several people say they don't like= to drill through ribs. The old Steinways had a combination of screws throug= h every rib which were then dowelled, large dowels  up into the areas b= etween the feet of a footed bridge, and screws through soundboard buttons in= the high treble which were just left in place. Is there a better way, if on= e is using screws? It seems like drilling through ribs weaken the ribs, a ha= rdwood dowel through a thin softwood soundboard between the ribs could break= free later and buzz, and a screw left in place through a soundboard button = could loosen and buzz, especially since many are inaccessible. Suggestions? Thanks Bob Davis</HTML>
