Looks good sailor. Thanks for the pics too. It makes sens to keep the holes smaller to make the coals burn longer. Once I test out drilling I will decide which direction I will go. Is that one sheet of expanded for the top part? If so what is the length and height you used to make the circular top part?
Yes one sheet of the HD Lowes stuff I think the sheets are 12" x 24" . So this is 12" high. I believe that I used a replacement grate for the weber smokey joe as the base. I'll look at it closer when I get home, been several years since I built it.
