I have been smoking on an ECB with mods for years and want a small smoker that I can put a couple racks off ribs on. I don't really cook for a lot of people so a big pit would be wasted right now. I want a reverse flow with offset box so it is easier to get at the fire and easier to get at the food. I am in northern VT so I would like something I could smoke later into the fall if possible. Parts so far. I ordered a 11 gallon air tank from Harbor freight that I am going to use as the CC. It is 13" or so by 23". I have some 2.25" exhaust tube kicking around that I am going to use as a stack. Main problems in planning so far. The one issue I have is building the firebox. I have a 220 mig and a DC tig. but my cutting abilities are pretty much just a 4.5" grinder. I don't really want to make large cuts in 3/16" flat steel Was thinking of making a angle iron frame for the firebox and then lining with firebrick splits and using sheet for the outside maybe. I have access to a large box brake and a plasma but the plasma is my neighbors and It was having issues cutting some 1/4" plate that I needed cut so I had to go back to the grinder. What are people using to cut the large steel plates for the firebox? Plasma? I guess I could get 6" wide or so flat and weld it together instead of going at 12" plate with a grinder. Worse comes to worse I can use cutting disks but I imagine it will be less than enjoyable. Any firebox build ideas would be appreciated.
