Assembling the Middle Ring

Step 1

Lay out the positions of the Middle Ring Sections and Ring Connectors like so. We will also need six (6) 2×4 mm silver screws supplied back with Issue 73:

Steps 2-3

We’ve done these connectors before, so I am going to simplify things here.

Add a Ring Connector under the joint on the right end of Middle Ring Section BF-13, attach Middle Ring Section BF-15, and secure with two (2) 2×4 mm silver screws, as shown:

Steps 4-7

Repeat the previous step at the other end of Middle Ring Section BF-13 with Middle Ring Section BF-14, another Ring Connector, and two (2) more 2×4 mm silver screws:

Step 8

Connect the dovetails between Middle Ring Section BF-14 and Middle Ring Section BF-15, add the last Ring Connector underneath, and secure with the final two (2) 2×4 mm silver screws:

The middle ring frame should now look like this:

Building Up the Frames

Steps 1-2

Retrieve your Bottom Frame assembly from Issue 73. Fit this new Middle Ring assembly on top of the assembly, aligning the rods and upright supports to the matching holes in the Middle Ring, as shown:

Step 3

Connect the Middle Ring to the Internal Supports with four (4) 2.5×4 mm silver screws:

Connect the Middle Ring to the Support Rods with four (4) 2.5×8 mm silver screws:


This framework is starting to gain some real weight. Thankfully, it is also quite sturdy, as it will have to carry the load of the entire model. We will add more to this assembly in Issue 77.
