You’ve clearly spent some time wandering the aisles of a hardware store, staring at a bag of grey plastic and thinking, “I could conquer a galaxy with these.” You’re absolutely right: to the uninitiated, they are rebar chairs or slab bolsters, but to the budget-conscious wargamer, they are the backbone of a low-cost, high-impact tabletop invasion.

About a half a dozen lengths cut to size.

If you are playing Warhammer 40,000 or Necromunda, you know that “Gothic Architecture” is just code for pointy metal things that look uncomfortable to sit on and of course archers. You’ve just gott have those! Those circular wheel spacers, used to keep rebar off the ground, look exactly like sci-fi power generators or cooling vents. If you glue three of them together, spray them silver, and hit them with a brown wash for “rust,” you suddenly have a Promethium Relay Pipe that costs five cents instead of fifty dollars.

There was even lots left over.

I picked these up from a construction site dumpster but they are readily available.

I will paint these up to match the buildings when the last three buildings are completed.
