I have seen the copper type dish pads used in smokers this year. They are held in place at the tip of the smoker by a nail which has been driven through the tip of the smoker and through the copper pad inside the tip. The nail is held in place by some thin wire which wraps around the end of the nail on the outside of the smoker and goes over the top of the tip and wraps around the other end of the nail sticking out the other side. I was told this is a good thing to do to your smoker. It collects residues of the what is being burned in the smoker and it keeps the bees from getting burned by flames that come out of the tip of the smoker from over zelous bellows pumping when fuel gets low.
