Thinking about doing another small batch of patio sized smokers this year. Last year I did four 16" dia, 32" cc and 16" firebox cookers. Even with the problems I had with my guy that rolled the steel, I still had fun, sold three and kept one for myself and made a little money to buy a couple new tools off the deal. So I'm thinking of doing another batch, and even though this is just a hobby for me, I don't want to give away my time for free, and one problem I had with the 16" is that most people felt it was kind of small for a smoker and I kind of felt guilty charging what I needed to to get what I felt my time was worth. There is good money in the large trailer pits, but it's more work than I have the time or space or interest to do very much of. I'd like to do a patio sized cooker , and get a design down to one size, get the design to where it cooks perfect, and build jigs and buy my materials in bulk so I can pump them out a little quicker with less man hours and keep it a profitable hobby. So I'm thinking I need to just break down and order 1/4" wall pipe, and the size I'm thinking about is 20" dia, 40 " long Cc. With a square firebox that would keep the cooker less than five ft long. With this size, I can order one length of pipe at a time and have enough for six cookers, and six 2" slices to make 20" wagon style wheels. With the price of the pipe, the 1/4" plate, and trim hardware, I'm thinking it would put me wanting to get about $1000.00 bucks a pop. Still well under a comparable horizon or lang, but better! I'd model it somewhat similar as far as the wheels and cart as this 20" dia horizon, but of coarse it would be RW reverse flow with all my normal improvements, So what do you think about this size?
