Return to the BUILD

“This stage includes the parts you need to complete the passage tube. The top has a cutaway section, designed to reveal the interior by lifting off a removable panel after the hull plating is finished.




Materials: The Hull Frames, Radial Stiffening Rib, and Connectors are metal and the remaining parts are plastic.

Screws: I have designated the screws supplied in this issue as follows. See my Screws page for more details:

  • Parts #6 = Type F for Frames
  • Parts #7 = Type C for Corridors


  • Starship Fact File – Imperial Capital Ship: Star Destroyer Deployment
  • Secrets of Spaceflight – Life Support Systems
  • Build the Falcon – Assembly Steps


NOTE: The Hull Frames, Radial Rib, Connectors and screws will not be needed in these assembly steps and can be set aside for the next issue:

The Assembly Jig and Non-Slip Pads will not be needed in these assembly steps either. However, to keep us from possibly losing the Non-Slip Pads, we can install them now. Simply peel the backing paper off and stick them into the matching circular recesses, as shown. I also marked this Jig section with the issue number – I am not sure if it matters but it can’t hurt. Then, this assembly can be stored safely until we need it in a later issue:

Assembling the Passage Tube Top

Step 01

Retrieve your Cushion Pads sprue from the previous issue. Carefully cut Cushion Pad #1 from the sprue.

For details on how I cut and sand plastic parts from a sprue, check out Issue 07. To identify the different parts on this sprue used in this issue, we will assign them numbers as shown:

Test fit and then super glue the tabs of this Cushion Pad #1 into the matching slots at this location on the Passage Tube Top.

To determine the proper orientation of these Pads, test fit them in both directions:

For me, the correct position was the one where the flatter edge of these Pads are closer to the edge of the Passage Tube Top, as shown:

Steps 02-03

In the same way, test fit and glue the tabs of Cushion Pads #2 , #3, and #4 into the matching slots at these locations on the Passage Tube Top:

Step 04

Retrieve your Passage Tube Base assembly from the previous issue.

I temporarily fit the Passage Tube Top to the Tube Base and wrapped them with a rubber band. This was to keep them aligned for the mod zone below:

Continuing with my dirty, used theme, I went ahead and weathered up the interior of these Passage Tube parts. This was accomplished using Vallejo Game Wash 73.201 Black and, to a lesser extent, Vallejo Game Wash 73.200 Sepia. I used various tools to apply the washes, from brushes to cotton balls – this was to give a varied texture to the colors. For the patterns, I just imagined leaking fluids, rusty areas, and where things were touched. I even added tiny footprints and some spilled drops of ‘coffee’ to the floor just for fun:

Completing the Passage Tube

Steps 01-02

Fit the Passage Tube Top to the Passage Tube Base, aligning the tabs along the edges and the top holes to the Corridor Arches.

If you waited to install the Arches, now is the time put them back in:

However, it is important to note that they are directional. If you look at the Arches, this small locating pin at the top of the ring is off center:

When fitting these Arches, the locating pins should be closer to the back wall of the Passage Tube:

Then, the Passage Tube Top will line up correctly:

Step 03

Secure the straight ends of the Passage Tube Top and Base together by slipping the Passage End Ring over it, as shown.

On my model, this was not a very tight fit. If you do not plan on taking this tube assembly apart later on, I recommend gluing this into place:

This is what my painted Passage Tube assembly looks like from a different angle:

Steps 04-05

If you choose, you can also test fit this Passage Tube to the curved Corridor to see how it will eventually be attached:


I have seen other builders put mirrors at the open ends of these tubes/corridors. I might do the same once I see how they look inside the ship.
