Hatch covers were molded off the strip-built covers. Lantor Soric was used as a core as and flow media, with a single layer of carbon on each side. Because they were small parts, Raka 127/606 was used for a faster cure than the ProSet. Notice the resin front times/distances, and compare to those for the deck on Infusion page 5. The cell pattern of the Soric was filled with thickened epoxy.

The cockpit had been trimmed at the edge of the recess in the strip-built mold, so it was necessary to build a new recess. Here, the plywood insert establishes the inner edge of the new recess

The recess was shaped by draping .125 in thick Divinimat and tacking down the inner and outer edges with hot glue. The Divinimat is scored on one side and has a glass scrim on the other, so gentle compound curves are possible with the scrim on the convex side. A single layer of 3 oz E-glass and epoxy stiffened the recess enough to turn the deck over and apply a nother layer of 3 oz to the inside.  After trimming the edge, a wet lay-up of unidirectional carbon was vacuum bagged on both sides of the recess.

A mold was taken from the strip-built coaming, and a carbon/Soric coaming was infused in the mold. There were a few minor issues with the as-molded finish, so after a little filler and sanding a single cosmetic layer was bagged in place using wet lay-up. The coaming was joined to the recess with glass.
