like chip, i use cedar chips and like chip i cheat and use a flame thrower........
(small butane torch).
i use a larger smoker, but what i do is add paper in first, like 3 sheets, from my insurance company booklet..........
(better than newspaper). crumble loosely, shove in/compact a little with hive tool.
anyways i put that in, fire the butane torch on the paper, then add chips, like iddee said puff it and add. i puff it until the flame comes up through the chips add more chips, puff again, until the flame comes up through the chips again, add more chips ( a little at a time) and then pack more in........puff until you get the cool smoke coming out.......good to go, never goes out on me. like iddee said, stays lit.
