“As with the left knee, it is essential for the structure of the Mark III armor that the knee joint is firmly secured and as well fitted as possible.”

This issue will be very similar to the work we we did on the left knee back in Issue 32.



Materials: The Upper Right Knee Joint, both Rings, and the Spring are metal while the Washer is plastic.

The Right Knee Joint (4)

Stage 1 – Fixing the Adhesive Tape
Step 1

Remove the backing paper from a piece of the Adhesive Tape, then stick it to the edge of the Washer as shown:

Remove the backing paper from the other side of the Adhesive Tape:

Step 2

Fit this Washer (with the Adhesive Tape facing down) inside this circular recess of the Upper Right Knee Joint, as shown:

Stage 2 – Gear Ring, Rotating Ring and Spring
Step 1

Retrieve your Knee Joint assembly from Issue 49. Fit the Right Knee Gear Ring (with the gear teeth facing up) over the empty post as, align the two mounting holes as shown, and secure it into place with two (2) LM screws.

I temporarily removed the previous Lower Joint assembly and Spring for better visibility here. This is also your friendly reminder to try using 3-in-One Oil on all screws going into metal:

Step 2

Place the Right Knee Rotating Ring on top of this Right Knee Gear Ring, meshing the teeth of the two parts together as shown.

Remember, the tabs of the two Rotating Rings (arrow below) will need to be aligned into the slots of the Knee Joints later on:

Slide the Spring down over the post onto the Right Knee Rotating Ring:

At this point, I replaced the second Right Knee Rotating Ring and Spring I removed earlier:

Stage 3 – Completing and Closing the Knee Joint
Steps 1-2

Fit the both Right Knee Joint assemblies over the Springs, as shown:

Again, be sure the tabs of both Rotating Rings are aligned into the slots of the Upper and Lower Joints:

Steps 3-4

Retrieve your Cover for Right Knee Joint assembly from the previous issue. While keeping the internal Washers in place, bring the two halves of the knee joint together as shown. Secure these parts together with two (2) IM screws.

This was not very easy to do, trying to align everything and at the same time compress the Springs. Take your time and you will get it. Once this is secured, make sure your Knee Joint mechanism is stiff but able to move. This joint has to support the weight of the model:

Step 5

Retrieve your Screw Cover from the previous issue and press it into this hole on the Cover for Right Knee Joint, as shown:


These Knee Joints were a bit tricky and required a good squeeze to keep them together long enough to drive the screws in. Luckily, we now have both knees complete and can move on to the hip.
