I’ve been making beard combs for about a year now. It used to be, laser engrave with my 2.8w jtech laser diode, then mill the shape with a 1/16" down spiral bit, all on the cnc machine. Then sand. Then 3 to 4 coats of shellac. It was about 30 minutes of hands on time, 30 minutes of machine time. That was a lot of work for $12 each.
With proofgrade thick cherry plywood, its 12 minutes to engrave and cut, package, ship.
When figuring in time and extra material for finishing, you just can’t beat proofgrade.
