The core is placed on top of the wing sheeting and the top sheeting is later folded over top of the core.

I pinned the sheeting to the cores in the appropriate location.

The sheeted cores are then fitted between the shucks. Pin parts together insuring that parts fit properly in the shucks. Tape the parts together so that pieces don't move while drying.

Place the wing core on the plastic tarp. Tape a piece of twine down the side of the cores. Place a long piece of paper towel on top of the cores. Tape the vacuum line near the twine.

Apply a bead of latex caulking around the cores. Fold the plastic tarp over and seal the edges by stepping on the tarp to smash the caulking together. Apply a couple quarts of paint near the center to insure parts are straight.

Turn on the vacuum pump and pull about 5 inches of Hg. My pump turns on around 3 inches and shuts off around 6 inches.

The finishing epoxy typically dries overnight, but if it is cool it will take longer to dry.
