I stole this idea from Responsible Jon's moped blog. Straight up Stole it.
I got a file cabinet off CL, took all of the controls and heating elements out of my oven.
Maybe I shouldn't be showing pictures of this mess...
Plasma cutter makes quick work out of all the sliders inside the file cabinet.
I have lots of work to do. Next is to make a door, wrap the whole thing in fiberglass ceiling tiles, mount up the heating elements and wire it all together.
