Here's some pictures of the build so far. Its been slow going mainly because I want to keep this enjoyable and the beer consumption usually slows me down. This is whats been done so far and what I'm thinking of: removed and discarded the old insulation, to be replaced with formaldehyde free non-batted insulation, removed all the plastic and rubber trim and replaced it with steel, cut in an inlet vent - 10x2 floor vent with damper, cut in exhaust vent - 4" dryer vent with flapper, installed 1000 & 500 watt hot plate burners with controls, installed 1/8 1x1 angle iron for selves. I want to keep this project relatively inexpensive, so I used a modified hot plate for the heat source, but I'm not sure if they will withstand the prolonged heating. Any thoughts?
