My uds is still a work in process - but am getting closer to pictures. My fire basket is 12"x48" of expanded mesh, with a 14" diameter expanded mesh grate 3" from the bottom.
Initially I used the 18" el cheapo table top grill for an an ash pan. It worked, but I felt it was keeping my temperature down. I switched to a 16" commercial pizzia pan this weekend. It is much thicker/stronger than the el cheapo grill.
Temp was marginally better - but was working with minimal charcoal (only had sausage and abt's on the grill. Will run a full test again next smoking.
Anyway, I really liked the Acemart pizzia pan - it was about $8 and about 3/32 thick.
