“We’ll begin assembling the thoracic cage this issue, build out the spinal frame, and add a vertebra to it.”




Materials: While the Thoracic Vertebra Part is metal, all of the Thoracic Cage Joint parts are chromed plastic.

Components for the The Thoracic Cage Joint and Vertebra

Step 1

Fit the post of the Thoracic Cage Joint (Top) through the hole in the end of the Thoracic Cage Joint (Shaft).

I don’t think it matters, but the two halves of the ball have different posts inside. To start with, we will use the one on the left:

Step 2

Fit the Thoracic Cage Joint (Top with Hole) into the other side of the shaft, completing the ball:

Step 3

Secure these two cage joints together with one (1) PM 3×6 mm screw:

Step 4

Retrieve the leftover Cap from the previous issue. Fit this (hollow side down) into the matching socket on the Thoracic Vertebra Part (37-1).

The Cap should be sitting flush in the socket:

Step 5

Retrieve the Thoracic Vertebra Frame from Issue 35. Fit two (2) M2 nuts flush into the recesses at the lower left end of the Thoracic Vertebra Frame, as shown:

Step 6

As we have done before, fit the Thoracic Vertebra Part (37-1) assembly under these nuts, aligning the holes and pegs:

Step 7

And like before, while holding the nuts in place, turn the assembly over and secure them with two (2) PB 2×6 mm screws:


These recent issues have been quite small, but we are indeed inching our way to completion of the chest frame.
