I have been using what you all on here call a UDS for sometime now.. Recently I have built what you also refer to as a double barrle smoker where the barrles are stacked on top of each other.. I have never smoked on a true wood smoker before and am in need of some guidance.. I have read some of the threads on here but I am still a little confused.. I understand the whole getting the fire going thing I am just curious as to when you actually add the wood that you are using for flavoring.. Do you add it while youy are trying to get the fire going or do you wait until the fire burns down and you get a steady temp reading before you add it? Any help would be greatly appreciated!!!!
