Started yesterday to season a newly built RF that I made. I need to iron out some kinks I have. First heat 186F digital therm. was max temp firebox damper inlet too small. Opened up a new hole and fire started coming alive. Then I needed more hear into cook chamber opened that up quickly with plasma cutter. Fired it up again 208F max, I'm fairly sure my exhaust is to small. Before i start grinding por15 heat paint off cutting and welding a new exhaust ( thinking 5" X 30") I figured let's ask more experienced people. I know of the calculator, just not sure about reading it

It looks like the fire box is too small and the chimney is a little small. It's a pretty big smoker.

So inside even with the firebox top plate, there is a 1/4" thick baffle plate that runs all but the last 10 inches. I have just shy the capacity of my camp wood stove the Fisher papa bear, I figured it would be enough. I could be wrong though.

You need a bigger chimney to draw the heat out. Something that size probably needs a 5" ID pipe at least 36" high with bigger fire box vents. It looks awesome though. Nice work.
