I have been watching this forum for a while now, and decided to build my own smokehouse. I wasn't going to post it on here but I think its turning out pretty well and wanted to share. I started with a bunch of leftover 2x4's and built a base and sheeted it with 3/4" plywood. The dimensions of it were 3'x5' and then built walls 6' high and put a roof on it. I insulated the walls with wool insulation and sheeted the inside of them with Durock concrete board. I am allowing for 2 -4x10" floor registers across the front and back for intakes and have a 6" chimney with a damper in the back. I am going to be sheeting over the concrete board with 22 gauge aluminum and putting tile up the sides 24" around the burner. I am going to side the exterior with hardie board siding. The cost got a little carried away but I can't stop now. Let me know what you guys think and if you have any suggestions let me know!
