the downhome homemade smokers i've seen have been constructed of a trash can in the ground, with a smoke hole out the top with 6 inch pipe run horizontally to the bottom of an old refrigerator set on a terrance.
a hole in the bottom of fridge admits the pipe from the trash can, and a damper and exhaust in top of fridge allows airflow to emit. shelves in the old fridge are handy for holding the smoked meat.
not the prettiest sight imaginable, but practical. kinda like something in Mother Earth News way back yonder.
