Amatuer. Latin Amator. Devoted pursuer of an object.
I am an amatuer luthier in that the $$ pays for pleasures and the work is done for enjoyment. This does not detract from skill or talent. I have no miter saws, only dovetail. No guitar I have made or repaired uses mitered joints. Lutherie only involves stringed instruments. Those that are plucked and those that are bowed. Now a Harp may have mitered joints. Some banjo rims start with 22 1/2 deg. mitered joints and then turned round.
No more from me on joints!
