The outline of the properly positioned bridge is cut through the finish with a sharp knife.
Then the finish under the bridge is removed very carefully using paint remover and chisels as a scraper
The footprint of the bridge must be clear of finish to get a strong glue bond between the sound board and bridge.
A temporary clamping caul is placed against the bridge plate inside the guitar and the bridge is glued and clamped, here with four wide C-clamps with Teflon pads. In this 12-string there are two “insurance” screws inserted through the bridge after gluing. The holes for the screws are filled with wooden Ebony plugs and made flush with the bridge body.
