Strap clamp does work but does distort the bottom just a little. I
may need anothe clamp nearer the bow. I may also still need a little
thicker stringer at the bow.
BTW, "Gorilla Glue" does work for flat pieces but I was easily able to
separate the sides from the stringers (well, not easily, but at least
possible) so I will use epoxy for any parts under tension.
