so a few q's that i have. i want to make it into a upright coal smoker. it has a metal insert and insulation then the outer metal. the metal insert is real cool and has a small compartment and a large one. my idea is that i can place a coal basket in the small section and drill holes into the divider then racks in the large section. can i leave the metal insert and insulation in it? it will be a 250*-300* smoker. any coments will be appreciated, thanks tim ps i will post pics tommorrow.
