I've got some barrels and a decent setup idea for a double barrel build. As I've been looking at all the builds I have seen the same diagram with stacked barrels, stope pipe coming up the center bottom from the firebox to the smokebox(barrel) with dual exhaust out the sides. From reading it looks like using flews and such in the stovepipe is for heat/smoke control. Here's my question/idea: Would running dual stove pipes out of the sides of the firebox then into the smoke chamber naturally control heat smoke? Or would the heat diffuse too much? I've attached a diagram. Thanks!
