Gidday Graham,
Do you mean to install a ply closeout template just inside the trailing edge
of the fin, where the foam closeout block is attached? If so I imagine you
simply dug out enough foam to insert it. Am I on the right track? By the
way, the massive beam you speak of, did you attach it with double sided
tape, and did it stand up to the postcure temperatue OK?
