So, I've cut into my ammo can, as I'm not happy with the smoke (lack of) on my new masterbuilt 30, unless I'm at high temps. After reading a bunch on here, I decided to try the mailbox mod. I didn't have a mailbox, but had an ammo can, someone here has this setup I believe. As you can see from the pics I cut a 3 inch hole in the back, drilled 3 3/8" holes for intake (maybe not enough?) and set out to smoke some ham, and andoulie sausage this weekend. Unfortunately I don't have pics during smoking, because it was Very windy on Saturday, and the temps were in the mid 20's.....to cold to pull the phone out. Anyway, the can started great, for about an hour, then extinguished (I had my amaze-n with pellets, 2 rows, nuked, they are dry) I know this can is waterproof once shut, so I wonder if I need more intake holes? Any advice would be helpful, thanks!
