Then centered a forsner bit over the bridge pin holes and notch, then drilled into the bridge root. Filled the hole with a Dilignit plug - epoxied it in. Then trimmed the plug flat to the bridge cap with a chisel, drilled new bridge pin holes and carved a new notch, inserted new bridge pins . Acton Dag hid the bulk of the repair. Worked just fine and not very difficult.
