I'm not sure if this is the smallest functioning smoker ever made, but it's got to be close. The smoke box is a 10 gallon tank and the fire box is a 5 gallon tank. Here's all the pictures, from build to seasoning to it's first smoke. Let me know what you think. It all started with a good washing and burn. Then came the layout. I'd never tried to connect two round objects before. Not as easy as it sounds. The welds look like crap. My MIG broke at the beginning of this project, so I broke out my old ARC, which I had no experience with. Things got better as a I went, but the welds are still ugly. Oh well - function before form. After the initial burn it, it got a coat of BBQ paint. Here's the first effort with the smoker - 2 - 9lb pork butts. I used a mustard coating and a mild all-spice rub. I didn't want to over power the pork flavor on the first smoke. I wanted to see what the lump & oak would provide. It held the temp pretty well and more smokes will make it easier. The mini sitting next to the Big Daddy. I put the butts in at 7:30am, pulled them at 5:50 pm with meat temp at 190. I double wrapped the butts in foil and placed them in a ice chest with towels for 1.5 hours. The final result was fantastic. Great pulled port sandwiches with cole slaw. I can't wait to do a brisket next weekend.
