Here is the Nesting File (done by hand) for the 1/4" and 5/16" hull components ready to be cut on our router table.
We use both imperial and metric and prefer metric. This boat is metric 9.912 meters so 32'6". The 6" deep frames are actually 150mm
We settled on router table as there is no heat distortion (plasma) and not foreign material introduced (water jet).
We've cut the 1/4" and one of the 5/16" x 5' x 27' plates but these plates are not flatten properly so I may send them back and change the nesting so we can use 5/16" x 5' x 20' plates instead.
Below are the 1/4" frames and the 5/16" long bulkheads slotted (egg crated) together.
I wasn't sure if this would work. The alternative was to spit the frames into 3pcs. The 5/16 x 16' long bulkheads have a 22 degree bend. This keeps them perpendicular to the hull plate while still leaving room for the fuel tanks. Other than wresting with the curved 5/16" plate it went together easier than I thought.
Frame 1 (at the bottom of the picture) has what is call "a floor" tacked in place. FYI...it(the floor) is 2x bigger than it has to be. Floors are used to reinforce the connection between the 2 side of a frame. Like a collar tie does in a roof truss.
Frame 6 (at the top) is one of the water tight bulkheads.
Frames 2,3,5 are under the fuel tanks as such will have smaller floors added later.
Frame 4 is between the fuel tanks is 13 3/4" (350mm) deep. It has a 3/8 x 2" flat bar welded to the top as a flange.
Take Care
