Ok so I got my drum done but wanted to do a test fire before I try to cook in it. Loaded it and lit the charcoal and 3 hours later the temp is only 150 deg. All the charcoal is burning. I have 2 ¾” air inlets made with black pipe nipples and 90 deg elbows 12” of pipe and ball valves on each. I was running with both valves open. The charcoal basket is about 12” high and held 3” off the bottom of the drum. The lid is made from a piece of 22 gauge sheet metal with a 2” vent hole in the top. I wanted to take picks but it’s now dark outside. I am sure this post is not great but I am trying to type it while being Mr. mom today and the 10 month old wants to play with the computer.
