I have a 1" hole saw bit that I bought to make holes on the UDS. I'm going to be building one of these Mini WSMs for a friend and I might give it a try. If it works, I'll go buy a 3/4" version of it. Since the aluminum is so soft, i have some significant flaring towards the inside of the pot where I drilled holes with the step bit. It is going to allow grease to accumulate if I don't use a drip pan and I'm concerned that I might get some flare-ups so I'll have to test that when I cook on this cooker Sunday and see what happens. I'm gonna toss some chicken on it Sunday afternoon...
