The build started off as a 1951 International Harvester fridge. I stripped it out, plugged all the wholes with guage plugs and gave it a good cleaning. Next came the element which I consulted the forum on and came to the conclusion that a 900w finned heater would work. I mounted the heater to the steel liner and cut a hole in the crisper door for it to act somewhat as a drip pan, then swaped out the glass in the shelf for some expanded metal. I was set on a smoke generator so my dad said he would tackle it. He built it with O-rings and it seals like no other. I am also lucky that my dad is a controls and meters guy so he had a ABB C50 PID laying arond that we decided to use along with a timer. The switches on the control panel are for power, the smoke generator air pump, and the timer.
