Step 8: Growth Rings
Using tape, we lay out the growth rings. The tape allows us to fine tune the rings and move them around after checking sight lines for driving and the realism of the look. It is at this point that I introduce the crew to two rules. The rivet placement rule (where the rivets will fall on the metal strapping) is used to make them look consistent and "right". The second rule is known as the golden ratio found in nature, also known as the Golden Mean; and that became the name of our snail car.
With the use of a 20 ton press and dies, we make fake rivets on steel strap and begin replacing the tape with metal parts. Each one has to be custom cut and bent slightly to "poof out" the frame of the shell.
Next, each rivet has to be polished with a wire wheel to give it the illusion of being a separate piece of steel.

Why not actually rivet it?

likely the same reason that welding is used over rivets in most applications. Effort and I imagine welds are stronger than rivets.
