“Insert the battery box, connect it to the circuit board, and use magnets to close the skull – then build out a searchlight for the base.”




Materials: The Back of Head and Magnets are metal, the Rubber Washers are rubber, and the rest of the non-electronic parts are plastic.

Connect the Battery, Attach the Back of the Head, and Fit an LED into its Housing

Step 1

Retrieve your T-800 endoskeleton and lay him face down. Retrieve your Battery Box (from Issue 3) and insert it into the T-800’s skull with the wiring to the right side of the head, as shown.

The sliding power switch should be at the top of the skull:

Step 2

Fit Rubber Washers over the end of two (2) 1.7×4 mm PWB screws. Drive these PWB screw assemblies into the narrow ends of the two Neck Connectors to create threads, then remove them:

Then, slide the wide end of one of these Neck Connectors down into the open end of the Ribbed Shaft (from Issue 104), as shown:

Steps 3-4

Slide the upper end of this Neck Connector into this matching hole in the bottom of the skull:

Then, secure the Neck Connector to the skull using one of the PWB screw assemblies from the previous step, as shown:

Repeat these steps to connect the other Neck Connector to the skull in the same way:

Step 5

Starting from the bottom left of the board, going clockwise, connect the skull wiring plugs into the Circuit Board as follows:

  • Eye Motor
  • Left Eye LED
  • Power Cable
  • Right Eye LED
  • Jaw Motor

Step 6

Place a drop of super glue into each of the larger round upper sockets of the Back of Head. Then, fit the larger 5mm Magnets into these holes:

Step 7

In the same way, super glue the two 3mm Magnets into the smaller round lower sockets of the Back of Head, as shown.

Once all four magnets are installed, be sure to let the glue fully dry:

Step 8

Tuck the skull wiring cables into the skull so they are clear of any magnets, then fit the Back of Head to the skull so the magnets attract each other and hold it in place:

Step 9

Gently bend the leads of the LED and Cable so they fit into this notch of the circuit board, as shown:

Fit this LED and Cable into the LED Housing (part 107-7 with the solid ring) so the circuit board fits into these four matching lips, as shown.

These LEDs must be pretty bright as the back panel of the circuit board here is an aluminum heat sink plate:

Step 10

Thread the plug of the LED and Cable through the center opening of the other LED Housing (part 107-8), as shown:

Step 11

Fit the two LED Housings together as shown, align the screw holes, and secure the two parts together with four (4) 2×4 mm PB screws:

Step 12

Fit the Lens for Searchlight over the exposed LED and press it down into place until it clicks, as shown:

Step 13

Thread the plug of the LED and Cable through the wider end of the Searchlight Stand, as shown:

Then, slide the Searchlight Stand up and around the rounded tab of the LED Housing, as shown:

Step 14

Fit an M2 nut into this matching hexagonal recess of the Searchlight Stand:

Step 15

While holding this nut in place, secure the Searchlight Stand to the LED Housing from the other side with one (1) 2x10mm PM screw.

Make sure the wire is out of the way before inserting this screw. And, tighten this screw enough that the pivot joint is not sloppy, but loose enough that you can still rotate the joint by hand:

This LED will emit blue light, so I used a piece of blue electrical tape to mark the cable for future reference:


With this issue, the build of our T-800 endoskeleton is now complete! We have also started to construct the futuristic display stand that will support and light the model as well as play sounds – all by remote control. Keep your T-800 safely stored until we place him on the completed Stand in Issue 119. The Searchlight assembly will be needed sooner, in Issue 113.
