    I thought i would share the Feldon Calc link with my measurments.

    the only thing that is a little strange from what I have seen on other builds, my chimney is a square pipe.  I caculated the volume and it matches the recomended pipe diameter.  I have 6 inch sqare and its ~29 inches  got the pipe for free and the math matched.  Its 1/4 inch thick and I actually like the way it looks compared to the circle stacks...

    nice looking build i am currently in the beginning stages of mine.Drawings and calculation stage  was thinking of a 250 gallon build with rib boxes and gas assist kind of like a bubba grill smoker. But my brother in law might be able to get me a 500 gallon tank for nothing so plans might change.

    From this point on, it has been in my garage and I have been working on it with a Flux core Mig.

    Got the flat iron welded on the doors

    Did a ton of research on hinges. I went ahead and made my own with 1/2 rods and tubing.  I ended up welding them onto angle iron to raise them up a bit.

    Next, I started building the ash drawer.  I am really happy with this addition. It will keep the hot coals of the bottom of the box. It will also act as another air intake if needed.  Most importantly, it keeps the hot coals off the bottom of the box.  Its easier to replace a drawer than the bottom of that box.

    I wish I would have thought to have the warming box open the way you did. Looking good Jack! Thumbs Up

    Thanks Solaryellow!  It was kinda an "oh yeah" moment when I started to make the cuts.   I had it planned on the back end, but changed it as I was making the cuts.  I had been drawing and planning it for months.  I thought of it right as I started to make the cuts on the back end...

    I ran the pipe with some elbows to bring it closer to the edge of the trailer

    I am starting to look into a sink addition on my reverse flow build. I am pricing out tanks. Any advice on a good tank size and brand for both fresh and grey water? I am penny pinching as much as possible. I was thinking of a 20 gallon, but they are more pricy than I expected.   Also, any advice on a good DC sink pump? All the pumps i see are rated for more GPH than I was hoping for...

    Thanks!

    I also decided to add equal stacks on the warming box.  I had only 2, but decided to add 4 on all corners to make for an even temp inside when opening and closing the stacks.

    oh and found a mascot as well
