Okay. I did the 55 gal drum with a to then a 6" Pipe out the top with vent hole near the bottom. I got too much smoke. So I added a 1/3 of a barrel in top that I attached the top to on top of the barrel held up with square tube. I get significantly less smoke with it. Most of it is drifting out the side but it is burning a lot hotter and faster. But I don’t think it is doing as good of job baking the logs I threw in.
Should I be looking at putting a skirt around the gap, making a more permanent way to set the barrel on top, or increase/decrease the air gap (1 side is 1/2" the other is 3/4 because that is what I had)?.
Also since I am now dumping water on it to put it out…How do you dry out the charcoal? Just out in the sun? It just leave it wet?
