I made a basic hot wire foam cutter

Hi everyone! Figured I'd introduce myself to the community by posting a thing I just made this morning.

I needed to cut 2" thick memory foam for some cushions I was making for my wife - using scissors felt awkward, so I grabbed some nichrome wire and ceramic insulators from a different project, and hooked them up to a variac to control the heat.

I was sure to connect earth ground to the stainless steel wire support and to the table to ensure it was safe-ish. All in all, not a bad result for an hour of side questing.
