does any one have any plans on how to make a smoke generator? also i was thinking since a cardboard box is safe to cold smoke in what about a 35 to 55 gallon plastic drum? i know it wouldnt be good for hot smoking but what about cold smoking cheese? i was thinking i could use a coffee can for a smoke generator. i just dont know how to light it and keep it lit. i want to get a a-maze-n pellet smoker but right now my funds wont let me. "funds being my girl and her daughter" lol. i have a little box i welded up in school but it is to small to use unless i put it in a coffee can and used that for a smoker. lol. so any ideas and if it is safe to use this drum i have?
