I have access to .140 thick pipe, which is about 10 gauge I believe, super cheap. I'm looking at build a 20" x 40" cooking chamber patio unit. My question is this thin of metal even possible to use to build a decent smoker. I'm in Texas so I'm not dealing with cold Temps very often. I've read that 1/4 is minimum but this will be a upgrade over my walmart special offset that leaks like crazy and is made with 18 gauge.
