Return to the BUILD

“The main parts provided are for the hydraulic actuator on R2-D2’s left leg, which mirror the components on the right. You also have a handy box to keep all your fixing screws in order, in preparation for the internal assembly of R2-D2’s dome and body.”

I took the photos for this issue (and the next issue) with my new Canon 90D DSLR. However, after a long micro focus adjustment session, I neglected to turn RAW format back on. So, I apologize if these images seem to be of less quality than usual!



Materials: Everything in this issue is metal.

The Screw Box

Why this screw box didn’t come with the first few issues is beyond me. Also, there are more than twenty (20) types of screws/nuts needed to build this R2-D2. I am sure I can find some use for it, if only to hold the screwdriver…

From the beginning, I was using this organizer so, unfortunately, this new one arriving so late in the build is basically useless to me:

Adding the Leg Details

Steps 1-2

Apply a small drop of super glue on the pin of the Hydraulic Arm Cap, then press it into the hole of the Hydraulic Arm Coupler:

Step 3

Glue the D-shaped end of the Hydraulic Arm Shaft into the the match hole of the Hydraulic Arm Piston:

Step 4

Glue the assembly from Step 2 to the angled slot on the end of the Hydraulic Arm Piston:

Step 5

Secure the mounting posts of the Hydraulic Arm Shaft into the two sockets of the Left Leg Outer Plate from Issue 38:

Step 6

Secure this into place with two (2) 2×6 mm silver screws:


A little more déjà vu with this issue as we are just repeating previous build processes on the left leg. We will continue working on this assembly in the next issue.
