So, while I have limited time for my hobby at the moment, and it is mainly going into prepping for running a game at a convention in May, I thought I would toss in an entry based on an objective I wanted to create.
A very large irrigation tank, filled by a steam-driven well pump. I started with a cardboard tube and my favorite base, the ubiquitous CD.
I then hotglued planking all the way around it...after filling the bottom with gravel to give some texture to the next step.
And then I put a bunch of bits together to look vaguely like machinery and a steam tank. Do I think it looks like something that works? No, but who cares, really. It will look impressive with paint on it. I had to wait a while though, because I filled the thing most of the way full with water effects resin.
Now, to paint and send in to the moderator!
