I have a smoke daddy i built and dont get me wrong, it works. It actually works too well to generate smoke. I dont even use the air pump. Last week i was making a batch of jerky and got to thinking about the differences between blue smoke, subtle white smoke, and too much white smoke. So i removed the center piece in my smoke daddy and put some glowing red lump charcoal in and dropped a chunk of apple wood and put the cap on. And for awhile i got a really nice subtle, steady trickle of blue smoke. Only proble is there wasnt enough lump charcoal inside to keep that chunk of apple wood smoking. I came to the conclusion i need a bigger container to hold enough lump charcoal to keep a chunk or two of wood smoking. So i thought i would ask some of the experts here at SMF if anyone has done any add-on mods to their MES30/40's that use charcoal and chunks of wood. All the mods i read about seem to use the AMNPS with pellets and im looking to use solely chunks of wood.
