It is a two drum smoker. Both drums are connected throug two 4" pipes with dampers inside. There are dampers on the two chimneys too. This arrangement is to be able to have the smoke make an "S" or "Z" path and force it to have contact with the meat. The upper drum is enveloped into a spiroduct section which diameter is about 3 inches bigger than the drum. The space between them is fille dup with mineral fiber. We can smoke about 4 to 5 -depending on brisket sizes- whole briskets and with a "secon floor" we think it would hold 2 or 3 more; -we have never loaded it that much-. We call it "the pharaoh" because of the four retractable pipes we use to carry it arround like when the slaves or servants of a queen, king or pharaoh used to ride the chief on public acts. I lacks and needs some wheels. "The pharaoh" was built about 5 years ago and was for about 3 years stuck away in my friends warehouse so we took pictures of it all dusted -you can see-; and then we cleaned it and lighted it for the smoke about two weeks ago that I mention on my introduction-to-the-forum post at which we had some problems that I will mention on another post or on this post's chain later on -there are things we did that should no be done-. We do not have pictures of the fist brskets that it cooked fo us. It takes "the pharaoh" 9 hours to smoke 4 briskets with mezquite wood and the results are very good per our humble standards. -We have not tried that many recipes, other woods, other people's ways or other rubs; only ours-. Just about to close the door: This is the first time we smoked a "different cut of brisket" that is sold here. It is a lot longer than the usual brisket we buy. That is one of the things that brought us some problems. I hope you like the Q-views. Regards.
