I've been reading and lurking around here for some time now. Had an MES 30 until it stopped working on me. I've made a UDS out of a 55 gal oil barrel and I enjoy that regularly. I have access to a pretty impressive shop, with a stick macine, a mig welder, a cutting torch, and a plasma cutter. I am no expert by any means.. I really want to make a horizontal smoker with a fire box. Undecided if I can pull of a RF or not... I got my hands on 2 16" diameter x 36" air compressor tanks, but the metal is pretty thin. Measuring with a micrometer, it reads .132" - just over 1/8"... Is this going to be too thin to make a smoker with? I can always make a square side firebox out of 1/4" or 3/16" steel instead, but will it maintain cooking temperature with the cooking chamber being 1/8" or should I toss it all together? What are your thoughts?
