Just thought I'd run over here and say howdy. I ran into this site looking for mods for my Brinkmann Smoke n' Pit and it has been most helpful. I already cured my smoker and went through a "dry run" of a beef brisket and 13 pound turkey and I have to say that they both turned out fan-damn-tastic! I learned some valuable lessons about temperature maintenance and also about how poorly-optimized these things are at stock trim. I've got some new thermometers to put in at grate-level today and I'm intending to go get some sort of an extension for my chimney and do a firebox mod of some kind, even if it's just to find a grate that doesn't set way down in the firebox and not let the fuel breathe (that was my #1 issue that made me "chase" the temperature all day on the first run). Anyway, I did have a question about the bricks some of ya'll have been lining the bottom of your horizontal smokers with. I can't seem to find "fireplace brick" at any of my local hardware stores and none of them come up with any results online, either. Can I just use regular bricks or am I missing something? Thanks for the great site and forums, though! I look forward to soaking up as much info here as I can to improve my smoking technique and really justify the smoker's place in the back yard.
