Here are the pictures, which speak volumes for the functionality.
As for the guts:
Steel 55Gal Drum
120V 15A input to work on nearly any household outlet.
Dual PID feeding control to a 25Amp SSR. (second PID used as alarm-limiting relay)
Dual PT100 RTD Temperature probes
Output to a single 1000W Electric coil burner with heat-fuse and thermostat bypass
6 qt cast iron pot for heat retention and woodchip holder
Two layers of Reflectix insulation: Single 25ftx24" roll.
Two 22" grill grates with stainless steel mounting hardware
Custom caster platform for easy maneuvering from storage to cooking location
I got the rig up to about 190 Degrees F before I put on the Reflectix Insulation, after that: hits 225 F in less than 12 mins (my favorite pork shoulder temp, have gotten over 250 when testing). Hold temperatures, with +/- 0.5 degree accuracy, indefinitely.
Have smoked 5-6 full shoulders, 4-6 racks of ribs, more sausage than you can stuff a snout with, peppers, corn, and other tasty items, all with simply perfect results.
I have a Bill of Materials if you are interested. All told, it costs about $238.15... give-r-take what you have lying around the house.
