I am new to this forum so I would like to say hello and I look forward to learning and sharing information. This is my first build. I'm an experienced welder and pretty damn good at building just about anything. I know that I want a 2x2x2 cooking chamber. I want to build a vertical reverse flow smoker with a water pan. I need some advice on firefox size and how to properly get the smoke into and out of the cooking chamber. I've seen a few different designs and I would like to incorporate some of both. Any advice would be greatly appreciated.
