With the grooves cut on the “L” stock they were ready to attach. First wholes had to be cut into the plywood platform to allow for the C-clamps to grab the mold without scratching the surface.
First he starboard platform was attached and allowed to cure…
Then the starboard platform was attached.
After the adhesive dried the gaps in the platforms where the grooves were made had to be filled and sanded smooth to ensure that the vacuum bag could achieve a good seal
The corners also had to be filled and faired to a smooth surface. Those areas where the top of the mold was above the platform also had to be filled-in to no sharp turns were needed by the vacuum bag.
