Here's the start of the latest project. Building a smoker out of an older upright freezer. The main fuel will be charcoal, but also adding a 1500W electric element and PID controller. Aluminum interior and exterior with 2" of fiberglass insulation in between. I'm hoping to reach 325 for smoking poultry. Outside dimensions are 51"H x 24"W x 24"D. The inside dimensions will be 40"H x 20"W x 22"D. 4 cooking racks and 1 water pan rack. Racks will be 20" x 22". This gives 1760 sqin of usable cooking area. If things go as planned (usually don't ), I want to get temps close with charcoal and bump it with the element for even temp control. The charcoal will go in a chargriller side firebox. I guess this smoker would be more of a vertical offset. Here's a few pics of the start. I'll be collecting materials and hacking away at it over the next month . Removed the old liner and foam insulation. Used a torch to burn out any leftover foam residue. Riveted .062" thick aluminum to the exterior to add some strength. Aluminum sheet is from a local salvage yard so looks kinda scuzzy, but will clean it up and paint later. Here's where the firebox will eventually go. Fun project so far, I'll post more in-progress pics as it goes . Tomorrow I'll start building in the liner.
