Working on the superstructure...
After the appropriate measuring, I have cut out two pieces to start my superstructure. The first piece is the most important, as it will face directly forward, behind the gun.
The first thing I do is cut out three holes. I tried using my exacto knife on the first, and broke the tip.

I blame that on my wife who was talking to me at the time.

I then use a more traditional method of drilling holes first and then cutting them out with the knife.
Here is a WIP shot:

I then glue in the portholes and door that I bought from Reviresco. I have a bunch of spare metal spears which I then started hacking into little pieces to make bolts and a hinge for the door. Once everything was glued in place, I took out my industrial file and had a go at the bolts to level them out a bit.
This is what it looks like now:

Extraordinary wouldn't you say!

This piece of superstructure will require seven sides and two upper deck pieces on top of it. Will get back to you when I've got this all pretty much sorted out.
Till then...
