Towards the end of the day, we created the rosettes that will go around the soundhole. In the center of that spot is one of the locator holes... and there's a special jig for the drill press that is centered on that hole and has an arm that extends and holds onto a vertical blade of just the right width. Lowering that down carefully creates the cavity for the strips of purfling that make up the rosette. (the depth stop is pre-set so there's no chance of going through). That top pic shows the bit in action. That blurry bit in the middle... that's the thing revolving at very high speed.
After the cavity is made, it is coated (e.g. shmeared with a paintbrush) with a sealant that will keep the glue from seeping into the grain of the spruce and causing a stain. Then we took 5 pieces of purfling (thin strips of wood)... 3 black and two white, and alternated them in a sandwich and squeezed them into the cavity (3rd pic). Once that was done, we floated in some thin superglue and let it soak into the purfling. Tomorrow, we will sand it down flush with the top, which will also take off that excess glue and sealant.
