One Step Closer to a Career as a Mad Scientist

Well, I made something in the garage that uses electricity and I managed to not kill myself or burn the house down. Score one for me!
As stated in a previous post, I have two great stacks of styrofoam sheets that are waiting to be made into tombstones. I also was able to find these even larger sheets of styrofoam at another construction site only a block away from my house.
I used a handsaw to cut this cross and base out of one of the large sheets of styrofoam. Cutting styrofoam with a handsaw is very messy and limits you to only straight cuts. I want to be able to have curved details on most of my tombstones, so I needed to devise another method of cutting styrofoam; one that allows for curved cuts and preferably one that is less messy. I know that many haunters use a tabletop hot wire foam cutter. That project seemed a little daunting to me, so I looked online for a less complex version. I found a couple of instructables for handheld versions of the hot wire foam cutter that seemed fairly simple.
Most of the instructables for handheld hot wire foam cutters call for wood in the construction of the base. I opted to use a length of PVC pipe that I had laying around. I applied heat and bent the pipe to create the arms of the hot wire foam cutter. I drilled holes in the arms, close to the ends and inserted eye bolts fastened with wing nuts.
Here is a close-up of the eye bolt/wing nut assembly.
Another close-up at an angle.
I stole the nichrome wire from a hair dryer that I found at the D.I. and I used an A/C D/C power converter or "wall wort" also from the D.I. to power the hot wire foam cutter.
Here is a cose-up of the wires attached to the eye bolt. No soldering required.
This picture shows the power cables secured with cable ties to keep them out of the way.
Here is a chunk of styrofoam on which I have drawn a simple design.
Here is the finished cut. Nice and smooth and virtually no mess. I am excited to cut out some tombstone forms using my new hot wire foam cutter that I made by myself.

I really like the design of your foam cutter. I've been wanting to make some bigger stones, but cutting them with a hand saw makes so much mess. I might have to make one of these.

Great work!!! Yes, a hot knife (if any kind) is so much cleaner than a saw.

Looking forward to more pictures.

Cheers!

Well Phil I think this year we will have to make some tombstones for my yard.
