Got tired of trying to get a firebox to seal. All I wanted was something that I could control the temps on and get good flavor.In my opinion this has got to be the easiest smoker to use. As you can see I had a weber lid. It fits perfectly! The drum was a sealed top that had coolant that goes in turning lathes and such to keep metal cooled while machining it. No liner!! I soaked it out for a couple of days then burned out the lid at work and ground out any sharp edges. I then used a propane/oxygen torch, at work, to burn it out the first time. I had it glowing red so I felt pretty good about the sterilization of it!! For vents I made two 1 inch by 2 inch slots and bent slide covers for them. I can get 450 degrees plus with these wide open!! Got a little dirt splashed on it from rain. Formed some legs for it so it can stay dry underneath it. Smoking Away!! I had already built the fire basket and it fit so I use it. That thing will hold a LOT of charcoal.The great thing is this smoker don't use a lot of fuel at all!! and when I am done all I do is close all vents and it don't take long for the fire to be put out. You can see I put two rows of bolts around it so I have two different grate heights. I can lower the grate if I want to stand a turkey up on it or something. I have some Hickory wood here so I have been burning that down for charcoal. Let it stay open while burning out the white smoke. Still got a bit of white in these pics, however after the coal bed gets established you don't see any smoke at all coming out of it!!
