I've found cutting HD foam inserts for Fin boxes to be difficult and I have shied away from that method. It occurred to me recently when installing FCS fusions on a planned twin Fin that I could just line the box with some 1 ounce cloth and overlap it beyond the box such that it would bond with the bottom lamination in the next step.
I know some have done used cloth in the routed out boxes but the key is to lap it outside and beyond the box so that it. Ones with the bottom lam. I'm prepared to say right here and now that a few strips of 1 ounce lapped this way is stronger than a HD insert.
Of course I have no easy way to prove this, but being an intuitive engineer, I think this is a pretty good guess. Anyone have any thoughts to the contrary?
