Pic 1 shows the real tank and you can see why the shape is so complex, it is a laminar flow shape, with the maximum diameter at around half the length and flowing lines to the nose.


I printed this photo and traced the outline as accurately as possible, resulting in pic 2.
Now, following yk's method, i pasted the silhouette on cardboard, and made a second print cut it in half and use that cross section as the holder for the formers to separate the segments of the tank model. I decided on 6 segments, see the redlines a to e on pic 3. These red lines also serve to measure the diameter of the bulkheads of the segments, which i drew on cardboard and cut out.

magnificent!! Ill be following !! Good luck!!
