wal-mart grill wok. (angled with holes in side and bottom) used this for lump and 1/2 hick chunk, 1/2 JD oak chips. put it on top of the rack where the cast iron box was for wood. put pan (no holes) on top of the lump coal and chips. used gas to lite lump charcoal then shut off the gas. used the gas to maintain temp as needed. saved on gas and made a beautiful smoker, and smoke ring.
