I bought these metal assault terminators back in the days of yore, and painted them up a couple years ago, when I got back into 40k. At the time I left them on the 25mm bases they came with, but always felt a little dirty using them. The time had come to make the move to 40mm, like modern terminators.
I decided to play with some weathering powders. I was planning on putting some of the static grass and flock I use for most of the army, to bring it together, so put in some browns in a few places to represent dirt coming through the cracked asphalt. I also tried putting some red around some of the bricks, to try to represent some bricks getting crushed and spread out, though I don’t think it really worked too well.
I snapped off the old bases and cut off the metal tab with a razor saw. The feet needed a little touching up with black paint from where I cut. I found a spot on each base where the feet would be flat, and pinned them in.
All in all I think they fill the base out pretty nicely, especially the lightning claws. Here you can see the static grass which hopefully ties it into the rest of the army.
Someday I might rebase everybody, but for now I’m telling myself that they’re tied in closely enough.
