GotMarko writes in with a hot wire foam cutter made from some posts on MAKE/Instructables – “A hot wire foam cutter and the jig I used to cut 4-inch styrofoam balls in half…Instead of the CD case project box, I just used a three wide plastic outlet box from HD to hold the dimmer and transformer. I cut the tabs off the sides since they were just in the way. Since I had some 1-by material around, I used that to make a small bow for holding the cutting wire. Twine around the top is used to tension the wire and can be adjusted as the wire heats and lengthens.”Link.

    Don’t forget to slacken off the tension when you power down, however.
