Rib bending using a bending jig and heat strip

Rib (maple, 1 mm thick) is first dampened then, sandwiched between a wet strip of cloth and the heat strip, carefully and very slowly bent around the form. The counterform is then clamped in place until the rib has cooled. Three different jigs are employed when using this method: one each for the top ribs, bottom ribs and C bouts.

Finished mold, with bent ribs and liners, "C" bouts glued in place
