Over the past 4 or 5 years on my haunt I have used alot of styrofoam. carry the white insulating foam. I like it and sometimes it can get messy. My tools that I usually use when I'm working with it is a rechargeable circular saw (usually when I'm cutting straight lines). I also have a Ginsu knife that I'll use when I don't have to cut something of great length. My other favorites when it comes to curves, cracks and carving texture ( take a look at my to coffins), are the set of foam cutting tools ( I would call them more like foam melting tools) that I got from the Hot Wire Foam Factory. When I first got them I really didn't like the way I couldn't get very good straight lines. But when I started to use my saw and then used the foam tools for the texture, everything started to come together.
The foam tools especially helped when it came to make the wood grain on the to ground breaker coffins. I didn't have to put alot of hand pressure on carving the grain. I also moved the tool faster so the woodgrain wouldn't be burned in too deep.
I also can't forget my trusty Dremel tool that was used for cutting the lettering. The letters were stock letter and number stencils that we bought in different sizes from Walmart. All of the were cut freehand. Liquid nails foam adhesive was used to glue the parts together. It's very strong and doesn't take alot of time to set up. When I had to glue the same pieces side to side ( like some of the double tombstones), bamboo skewers we used to hold them in place with the glue. Last, I picked up a torch to give texture and a weathered look for the tombstones and the boarded up windows.
