For this project you will need:
-Tape measure, straight edge, and a permanent marker
-Sheets of 4x8, 2" thick insulating foam, available at your local big box home improvement store.
-Sheets of 4x8, 1/4" thick luan, also available at your local big box home improvement store.
- Gaff tape, or other all-weather, all-temperature, all-purpose tape
-Liquid Nails or similar adhesive
-Circular saw & saw horses
-Elmer's Glue or Craft Glue, a bucket, paintbrushes, access to water
-Paint of your choice (we used flat black)
Note: You can substitute similar materials for the insulating foam, such as drop ceiling tiles, as long as it's light weight. Obviously you can also use a table saw to rip things down to size, but we are working in a pretty basic environment, and assume you are, too.
We made our cubes more or less 2" square, and we made six of them. Each sheet of insulation makes eight layers, and in our case it took 12 layers to make one cube. Since a cube has six faces, one sheet of luan for every cube. Simple, right?
Step 1: Cutting the insulating foam
When you have broken out enough insulating foam, prepare the surfaces by making sure they are clean and clear of grit, dust, or dirt. Apply the Liquid Nails to the top of the bottom piece, and then carefully place the next piece of foam on top, repeating until you reach the desired height. Be sure to straighten up the edges as you go to keep the cube square. Do this with as many cubes as you like, and then allow them to cure for the length of time indicated on the adhesive.
