Just as a review...we are going to try to remove the wood where the binding and purfling are going to go with this tool.
It is a gizmo that violin makers, and I guess acoustic guitar makers, use to cut binding and purfling channels...at least back in the days before 'lectricity and routers.
Basically, we sharpen the blade, set it to the right depth, and go round, and around, and around...
and around
and around
there are probably faster ways to do this stuff...but gosh, it is cold out in the garage where I have my router table. Even if I did it with a router, we would still have to do it by hand around those compound curves.
If you know what I mean.
