Started on one for SMF member Shamp... This will have a firebox on the side and effectively a series of tuning plates, and I'll be trying to direct the flow across vs. simply vertically. Started with an oil tank. Built frames for each side which fit tightly. These will eventually be welded to the sides, and will support other parts as well: Strapped them on and cut out a hatch in the front: Then I put together an "insert" which will slide into the hatch as an assembly and be permanently attached. The doors will be attached to this as well. I may use sliders...not sure yet. Doing it this way sped up the fab time considerably: That's about where I'm at. This one may or may not end up on a small trailer, which will influence FB design. Don't think pix are loading... Ribwizard...pulled the plug on a 230v mig welder...211 autoset. Still like stick for thicker stuff, but it will be nice to run .035!
