Bman here are the photos of the covers over the air intake tube and exhaust stack, very simple to make.
As you can tell I experiment alot, here are some of the most recent ones I'm using. I have the inlet tube on all and a variety of exhaust lids, however I find that the one with the 3 inch exhaust tube seems to do best for some reason than the ones with the holes drilled in the lids. Also if your UDS sits uncovered on the patio you don't have to worry about covering it or plugging the holes to keep water out, just close the cover on the stacks.
You can never have too many smokers!
