Realized i forgot to report here too:
After five years since the last report, there is some news to this project.
The bad ones, are as i did not have that place to continue working on them, for long, i barely advanced on the work, and i could not even try the spruce piece of wood i talked about before.
The good, got access to another carpentry workshop, and while i could not work that much on the things i showed here, i could deceive the manager into letting me do this one by telling it is the city walls on the city we are in, heavily simplified, when he told me to do some test runs on the machines.
As you can see it has been planned so the small cylinders can place infantry and tanks, the heliport on the middle can hold aircraft, and the entry points can be used by Titans.
The result is quite good, save for that i pressed the piece too much to keep it in place when i tried to do a last milling, and a small crack happened. I think it is not big enough to break the piece even if it falls to the ground, but big enough that the piece has begun to warp a bit, leaving a 2-3mm gap with the table, on its middle point.
