Last time I made bacon I used a pretty complicated arrangement of a stove and stove pipes to cool the smoke and guide it into my smoke chamber; this time I made myself a small and easy to maintain "Cold Smoke Generator".
16/14 oz. can
36 oz. coffee can
#6 metal screws
8" piece of 3/8" iron pipe
Several brass and copper fittings and pipe (get your idea from the pictures)
1/4" O.D. plastic hose
Some kind of feet (I used 3 shelf brackets) Make sure the apparatus doesn't tip over and set your house on fire!
An old aquarium air pump. (Even a new one isn't too expensive ~ $20).
Wood pellets or Hardwood! saw dust to fire the thing up.
Tools you should have and which will make completion of this project a lot easier -_^
Drill / Drill-stand
