ok well i recently aquired a few 55 gallon drums for free. there closed top food grade. now here is a few questions. i want the 55 gallon drum to be my main smoke chamber, with an offset fire box. but what should i use for the acual fire box. i thought about using two 55 gallon drums andjust offsetting them, but it would look "tacky" and i really would like a 20 gallon steel drum for it but for some reason there way way moreexpensive than a 55 gallon drum..(more wasted metal probly) any way any suggestions would help. and by the way, i am wanting to have the side by side offset and could use a few pointers all around. mainly how big the fire box hole to smoke chamber ratio should be for good smoke and heat. thanksalot guys cody kerr.
