“This issue, you’ll be assembling the T-800 Endoskeleton’s all-important lower jaw, and the first ball joint in our cyborg’s body.”

The instructions refer to the base of the skull as a ‘Lower Jaw’, but the ‘real’ Lower Jaw will appear in the next issue.



Materials: Most of this issue is plastic and rubber, except for the Lower Jaw which is metal.

Components for the Lower Jaw and Neck

Skull Joint
Step 1

Make sure your parts match the parts list above. You will need the Ball Joint – A, Ball Joint – B, and two (2) PB 2×6 mm screws:

Steps 2-3

Align the screw holes and push the two Ball Joints together. Secure with the two (2) silver PB 2×6 mm screws (the black screws will be used in later steps). The screws should be recessed after tightening:

Lower Skull
Step 4

Next, we will need the Ball Joint from the previous step as well as the Lower Jaw, Ring, and Ball Joint Socket:

Step 5

Insert the Ring into the hole in the Lower Jaw making sure it is sitting evenly:

Step 6

Drop the Ball Joint through the Ring as shown. This is the pivot point that will allow you to articulate the model’s head:

Step 7

Place the Ball Joint Socket over the Ball Joint.

If you can’t find this Ball Joint Socket, it may be tucked up inside the Ball Joint Cover inside the packaging:

Steps 8-9

Take the Ball Joint Cover and place it over the Ball Joint Socket. Align the three holes (it will only align one way), and secure into place with three (3) black PM 2×6 mm screws:


This assembly can be safely stored as it will not be used again until later issues. There was not a lot to do in this issue, but it contained some pretty important parts. All of these joints are going to allow us to pose our endoskeleton once it is completed!
