I've been scrounging parts up for a smoker and I have enough to make two types. I have a small steel drum about 14 1/2' Dia. and about 36" tall. Looks like a mini 55 gal drum, anyways I'm wondering if anyone knows if here are any grills or something that I can use for a lid? Most of what I find are too large. (18" or 22"). Any ideas?
