Welding the thin (19G) stainless was a major pain. On the second one I bought 14G steel for the inside skins and that made it easy. The outer SS skins were easier to weld as I had the 18" x 1" tubing to weld against. SS really moves when applying heat, much more so than steel.SouthamptonSmoker wrote: ↑July 24th, 2018, 12:36 pmwow, good going, done in a month.Pete Mazz wrote: ↑July 24th, 2018, 4:21 amHere's the thread.

I've since added an electric element for cold smoking and made sturdier shelves .
How did you get on with the stainless, did you go across large spans, and was the skin structural at all?
I am concerned about warpage, im pretty confident about the welding, patience is the key, but the inn and outer skin combined to essentially box section, so that is the structural part too. i would had to see it buckle first fire lol.
im using 3mm thick for the skins, 6mm for the baffle plate, not yet got to the firebox, but the oven will be 3mm, but instead of insulation, heat accumlation.
I am using 11 gauge all round, and I tabbed it because I know how bad ss is with heat. I intend to let each weld cool down before progressing to the next, they are pretty much 3/4" by 1/8".Pete Mazz wrote: ↑July 25th, 2018, 4:04 amWelding the thin (19G) stainless was a major pain.

I sure hope it does. I thought about the two flues before, with that exact thought in mind. But I would really like the reverse flow to work, and I guess I will cross that bridge if it comes to it. Essentially I would rather put in more holes because I failed, rather than in case I do.pr0wlunwoof wrote: ↑July 31st, 2018, 6:59 amFrom where I sit it looks like it is going to work. Might want to put two flues, one on each side, that way if you have to remove the baffle you can run it like a regular offset with maybe some tuning plates to adjust heat across your cooking surface.
