The arch on the back of our guitars is critical to the instrument’s ability to project sound well. Off camera, the back of the rim has been carefully arched using a paring chisel and a very sharp, low-angle block plane. Kerfed mahogany linings are then glued to the edge of the rim, as shown here. Once the clamps are removed, the back of the rim is carefully sanded with a large, perfectly flat, plywood sanding board, faced with 60 grit sandpaper.
