The docking rings were one of the first things I made so they've been sitting around for a while. First off was finishing the two side corridors.
This meant adding pieces to the sides and adding ledger strips and some center supports for the end piece.
The ends were capped off.
Armor plates were cut to fit the end cap and around the docking rings.
The plates were glued in place and some patches were added.
The docking rings were glued in place and corner brackets were installed.
Greebles were added by gluing parts from my stock onto a strip of .75mm styrene. Then gluing that into place. I've built up a stock of cast parts and added them in with a few individual parts from model tanks, planes and ships.
