I built this smoker. I first used the Northern Tools burner, which only reached 225. But that was without any meat, and I'm expecting 100 people this weekend. I know if I put in 40 pounds of meat it won't get nearly hot enough. So I put in a chimney starter full of charcoal, and it only reached 125. I realized the airflow was insufficient, so drilled over twenty 3/4-inch holes on the bottom, and 14 on top. While the first charcoal was still hot I added a second chimney starter worth of charcoal, but can only get it to 200. First question, how do I get it hotter with either heat source. Second question, am I better off with charcoal or LP? Third, I realize now that I need to better seal it. I ordered something off of Amazon, but it probably won't get here in time. Any idea where to buy it in the Twin Cities? Thanks for your help. My wife is getting nervous!
