This is my beast! Runs on propane. It used to be a 50,000 btu pork roaster and I capped off one of the burners leaving one remaining. The remamining burner I welded up 1/2 of the holes. It is now basically a 15,000 btu smoker. There is a grease tray on the bottow that I slide open to check on my AMAZE N Pellet Smoker so to not disrupt the heat in the box. It holds 7 commercial size (bun) cooking sheets that I drilled a shit ton of extra 1/2" holes in (over and above the perferated holes that came in them). That was the most work of this build. The pans are spaced about 5.5" apart and even the shelf supports have holes punched in them. I figured more the smoke could move around the better. It originally only had 3 shelf supports up at the top. I added 4 more. It does get a little hotter in the back corner where the burner is located so I hope to add a fan to turn this beast into a convection smoker (hopefully evening out the heat). With just the pilot lite I can hold the heat about 100 to 110 degrees. With the burner on its lowest setting I can achieve 190 degrees. Max temp is in the low 300's. I just smoked 60 pounds of peppers and it worked like a dream. If I had 10 more pounds I could have fit it on the final rack. So far I have smoked 6 racks of pork ribs and 60 pounds of peppers. Next task is learing how to make pheasant and Chuckar jerkey! Can't wait. This was a fun project. Little tweeks still need to happen like wheels on the legs. Mount a holder for the propane tank, add a fan and plumb the exhaust out my garage / shop. Happy Smoking! Kean
