First lamination

Today, we finally started building the most difficult of the frame ends. These are for the ten split frames around the centerboard, and they reach deep into the bilge, around a moderately tight curve.
Snediker decided that they would be build out of 16 eighth-inch slats, about two inches wide, laminated around a curved plywood mold. The slats are of knot-free quarter-sawn oak, about forty-two inches long, which is four inches longer than necessary. We plan that the frames will come out with one flat side, so that the other side can be planed easily and the bevel can be cut into the concave side to match the curve of the planking.
They are laminated using Aerodux-500 resorcinol adhesive which claims to be water- and weather-proof. Its technical specifications are excellent; it passes boiling and strength tests for use with exterior and underwater structural oak timbers.
Snediker made two inside molds out of four layers of half-inch plywood, cut to the curves of the frame templates. He drilled one-and-a-half inch holes into the center of the jigs to hold the heads of bar clamps and screwed a sixteenth-inch steel strap around the outside to help with clamping. Two frame ends can be laminated on each jig at one time.
He intends to recut each jig after using it twice. The first jig will be used for frames 29 and 28, the second for 27 and 26, then the first jig will be recut for frames 25 and 24, and the second for frames 23 and 22.
I can't help too much with the planning, but I became the apprentice cutting the slats from kiln-dried oak planks. When it came time for the glue, both of us were up to our elbows in mixing and applying.
We were able to assemble four frames in an afternoon. We used about ten liquid ounces of glue per frame; this averages out to 175 gm/square meter.
