Step 1: Preparation
Any type of EPS (expanded polystyrene) foam will work, from styrofoam that you find in the trash, to insulating foam that you buy at a building supply store. Foam that is more dense will sand to a smoother finish. For this project, two sheets of 1" thick pink insulating foam were glued together with an adhesive made for foam. This adhesive won't melt the foam and gives a strong bond.
- Spray both sides liberally with foam-lok adhesive.
- Wait 4+ minutes and then press together.
- Check for gaps around the edge and press them together.
The main concern in this project is that the walls aren't too thin and that the piece will have room for a tea light candle at the base.
Step 3: Cut Foam
- Cut the foam out with a hot wire, CNC router, jig saw, utility knife, scroll saw, band saw, laser cutter, whatever you have available.
- Leave some room when cutting the foam so you can sand it to the exact size.
