These photos show the upper bout rib being heated in the bending fixture. The first bend is the sharpest curve and most difficult. I have applied a spring clamp to temporarily hold it while I so the same to the other upper bout rib.
For this view I have heat bent the remainer of the curves in the two lower bout ribs and they are clamped in the master exterior mold. Here I am making a cut at the center join (in front of where the end pin will be). By cutting through the two ribs together, with a sharp exacto knife blade, they should fit tightly when glued under the end block.
Once the upper and lower ribs are bent and the blocks are fitted, they are clamped together in the master exterior mold. They are left to dry overnight (so they will hold their shape).
..Use linoleum spacers between the wood blocks and ribs to simulate the future glue liner strip thickness (so I can use the same clamp blocks for both operations).
