After the ribs are properly fit to the rim reliefs, and the new soundboard panel is fit to the rim, I am ready to index the ribs to the new panel. A hole is drilled through all the rib tips into the rim. Following that, a #7 bridge pin is installed in all the ribs and the 3 original indexing holes drilled before the old board was removed. The fit new panel is then placed on top, and the protruding bridge pins are press into the panel, leaving indentations. Using these indentations, the old board is laid on top of the new panel, and aligned to the 3 indexing pins. All the holes are transferred from the old board to the new panel. The indexed new ribs are then placed on the new panel, and traced. These holes will be used to locate the ribs when the board is pressed.
