I also occasionally use a clamp at the extreme treble end and a large hand-screw to reach in at the bass end. No holes through the ribs. Ever. Incidentally, this was not a problem with compression-crowned soundboards. Since the ribs did not support crown--they resisted it--the holes were of little consequence. If anything they would allow the rib to bend a little more easily. Hence, the hole and dowel or the hole and screw did not "weaken" the rib in the sense that it (they) would not affect the rib's load-carrying capacity.. It would with a rib-crowned soundboard, however. Del
