Why didn't I do this sooner? First off, thanks to everyone who has posted their builds. There just isn't enough room in my MES30 to adequately hang sausage, IMO. I don't smoke a lot though either so I decided to build a smokehouse that is quite a bit bigger than my MES but not overkill either. I was having a hard time deciding on materials. I was wanting to use materials I already have layin around. I have plenty of OSB but I'm just not so sure about the glue... and I didn't want to spend a lot on new materials. So I did some figuring and thought I had enough or close to enough short 2x4's in the shed to probably do the whole thing with. So that's what I did. I decided on 33'' wide by 30'' deep by 4' tall, outside measurements. The bottom ''layer'' of 2x4's is treated. It's below heat level and I had the treated in the garage so I figured it couldn't hurt. I then cut a piece of 1/2'' OSB for the floor. I'm covering it in ceramic tile. I then nailed together layers of the 2x4's until I got the height I wanted. I ended up adding an extra layer so its a bit over 4' tall at the peak. I went to Lowe's this morning and bought hinges, fire caulk, a grill grate, ceramic tile, a new forstner bit since mine was getting dull. It all went well. The day flew by though. Going to side it with plywood grooved panel siding that I had leftover from building my kids' fort. Oh, and have to install the chimney and lots of other stuff too. I'm going to add sheetmetal to the roof when I get to our farm where we have some scrap. I haven't decided yet on a heat source... I'll probably buy the Northern Tool burner Pops uses, but am tempted to build a pipe burner. If I had an orifice/venturi I would.
