Here is a closer look at the panels as they are drying.
Here you can see a couple of the panels standing up. They are actually a little shorter then 8? so that they fit into my living room standing up.
Here I am gluing 1/8? thin 4×8 sheets of plywood to 1? thick 4×8 sheets of polystyrene. These will become the brick walls of the dungeon. The polystyrene can stand on its own, but I wanted something that would be a little tougher to break to allow me to screw the wall panels to the pylons. I have a few pylons sitting on top of all the panels to apply pressure while they are drying.
