Hi ya'll, I just relocated from Dallas to SoCal in June of 2008, and after having trouble finding good BBQ out here, I decided to do it myself. I bought one of these $40 Brinkmann's from HD, and seasoned it overnight last night with about 10 lbs. of Charcoal and 3-4lbs. of Hickory. I was able to keep the heat relatively within the duymmy gauges "ideal" range, but It took alot of care and feeding. Plus the hickory I got was the chipped variety, thinking this would be better in this small smoker. Well, of course it burns up like kindling and didn't last too long. Anyway, I am thinking lump Mesquite and Hickory are in order for my halved shoulder tonight (about 4 lbs. each). My question is, how much coal and how much wood chunks can I expect to go through ? I am expecting right at 4 hr. cook time, but being that adding coal is such a P.I.T.A on this thing, I am going to probably extend that because I'll probably have it open for 5 minutes to add coals from my chimney-starter. Any and all feedback, links, and pointers are appreciated. I'd like to get the coals going and the meat on before noon so we can have pulled pork and slaw for dinner. Thanks.
