Been a while since I've posted, but been lurking quite a bit. I've been gathering parts, so I'm in the planning and cutting stages of my reverse flow build. Starting with a small trailer I snagged to $50, a tank I snagged for free $$ and a firebox that will be a recycled woodstove that I also scored for $50. I have a total of $100 in this thing so far so I think I'm ahead of the game at this point, although it has taken a bit of time waiting on parts to magically appear cheap, Best I can tell before cutting, the CC is 1/4" wall and the FB is definately 1/4". Plan something along the lines of M7's Chain hinges. Scored some large chain from work for free. Best I can tell I'm missing the reverse flow plate and cooking grates. Have my feelers out for wedge grating from the local coal mines for grates.. love the stuff. Anyway this is what I'm starting with, what do ya'll think. I know so far that I need to rethink the vent openings in the FB door. As you can see, the original openings are basic woodstove screw type, And I need both below and above the fire openings. So I need ideas or pics of what ya'll did there. New door? Using the calculators here I came up with the following dimensions. What do ya'll think Dimensions CC=54"x24" FB=28.5"x24"x21" CC volume - 105.75 gal FB volume - 61 gal so my firebox is larger than the recomended Vents - [email protected] under and [email protected] .5 over stack =8"d x 10.7 L And using the circle calculator Radias 12" Chord AB - 22.5 Segment ED - 7.8 Any feedback before I start cutting from ya'll is greatly appreciated.
