I separated the jigs and hot glued them to the table for the foam attachment. Note the longerons face out for access and clamping room.

A fuel cell finish nailer, instead of 5 min. epoxy, was used to affix the foam to the masonite. The sides held tight and after glassing pulled off from the jig like a Velcro zipper, leaving only pin sized holes.

The sides, upper and lower longerons glassed.
