Planning to build a standard smoker (not RF) out of materials that we have laying around where I work... lotsa misc machinery crap out in our "bone yard". So far I've scored a 120 gallon air tank, misc steel parts etc. The goal here is to have a it done in a few weeks for a car club get together and have zero dollars inversted! Altho, I may have to spend a few bucks here and there for a thermometer or something... I'll try to find the correct area to start a build thread and get some pointers from the pros. I was originally just going to put it together modeling on a factory built smoker we have at our facility but once again, my OCD has stepped in and won't allow that to happen.
