|Center drill bit by eyeballing bit edge with plug outer edge|
These specialist bits are not usually found at your local hardware, however you will find them at wood working machinery/tool suppliers. The most common size plugs are 3/8” and ½” of course those of you with European vessels will find the imperial plug sizes are close to metric equivalent or vice versa and will work.
Removing the plug is relatively straight forward, find the center of the plug by eyeballing the edge of the drill bit with the outer ring of the plug. Use the drill on slow speed and using light pressure carefully drill through the old plug. Be careful not to place too much pressure on the drill so that when it cuts through the wooden plug it doesn’t damage the screw head under the plug.
| Lightly sand the plug flush with the surface|
