Scorpion Mark III

Scorpion Mark III - by Thomas Tritt 1/19/14
This is the third Scorpion I have produced. As I did not write down a tutorial during the previous two constructs, the structure on this one might differ slightly (kinda 'wing-it' as I go). I used three ring sizes on this one, but only one wire size (16awg/18swg, or 0.0508 inches) of enameled copper wire:
- Large, I.D of 0.310 inches => AR of 6.10
- Medium, I.D of 0.200 inches => AR of 3.94
- Small, I.D. of 0.155 inches => AR of 3.05
There are additional structure supports, the legs, pinchers, and stinger that will be discussed below.
I did reference the anatomy of a scorpion for this construct. While not a perfect match, I did try for some accuracy.

The body is a European 8 in 1 sheet, as shown, using Large rings. The last 4 outside rings are pinned using a Medium ring.

A 'pin' is created using the same wire, then inserted through the outer edges of the sheet. The shape of the 'pin' will be adjusted slightly during construction to aid in structure.

Two additional Medium rings are placed in near the original pinning ring. These also feed through the 'pin' head.

The ends of the 'pin' are cut and shaped to curl around the last two rings of the second and fourth columns. Ensure the sheet is stretched slightly when determining final length of the 'pin'. Crimp the ends of the pin to their associated rings.

The arms use Full Persian 6 in 1 chains using the Medium rings. These are attached to the body, as shown. A third ring is added to help hold the arms horizontal to the body (there will be some droop).

The tail also uses a Full Persian 6 in 1 chain, but uses the Large rings. A wire 'support' is fed through the tail with a Double 'S' Curve on the end. This will be crimped in place holding two of the last rings for the chain. It will also provide a loop for another pinning ring, this time using Small. The last loop will be used later for the stinger.
The 'support' wire will be cut, shaped, and crimped onto the last two rings of the tail (again, ensure a snug fit'). The tail can now be curved into the basic shape.

The tail is now attached to the body using the last row of rings from the body, the middle column ring attaches to the top of the tail, the 1st and 5th column rings attach the sides and bottom of the tail.

Four sets of legs are cut (longest approximately 2 inches, shortest approximately 1.25 inches) with loops at one end. These are attached to the outer rings of the sheet (1st and 5th column), each leg fed through two of the body rings. Each leg overlaps one of the body rings with the previous leg. The legs are then bent to provide shape (I used 3 joints, but there is a smaller 4th joint in the actual anatomy).

Three circles were cut out of sheet aluminum (mine were just under an inch in diameter), one with a single hole, two with double holes. These are shaped to give definition to the pinchers and stinger (there is a slight difference on the location of the bends between the two structures).

The pinchers were attached to the arm using two rings from the arm. The stinger was attached to the single loop from the 'support' wire in the tail.
