I picked up one of the A-Maze-N pellet smokers thinking I would use it for cold smoking in my SM-045. I have the cold smoke baffle, but thought I would give this a try. The instructions say you can use saw dust or pellets. I didn't have either. I used some chips which are like course saw dust. I started the box outside of the SM-045. I could get it to produce smoke for more than 15 minutes at a time. I know that I have seen mention of using these things in the SM-025, and or the SM-045. What am I doing wrong other than simply not using the cold smoke baffle to start with?
