I'm building a lightweight kayak out of 3mm okoume and the deck beams call for stacking (3) 1/4" [6mm] x 1" x 26" strips of okoume to total 3/4" thick. Outer bend radius is 18" and 24" (so I planned on 16-1/4" and 22-1/4" inner bend radius to allow 1" "spring back." I don't want to buy an entire sheet of okoume just to make deck clamps and layering (6) 1/8" [3mm] sheets just sounds like a mess.
Does anyone have experience making deck beams out of different materials? If so what? I was thinking of taking strips of oak...will this spring back too much. In order to get the bend easily without steaming, I'm into at least 5 layers.
If I laminate 6 layers of 1/8" [3mm] okoume, it bends fairly easily. Should I bother worrying about spring back?
