i have an old fire pit in the back yard. the ring and lid fit perfectly on the drum for a taller lid if needed.
i have a bunch of old brass tubs and angles and fitting left from when i remodeled my old bar. my plan it to have intake holes drilled into the brass "handle" and control airflow by opening and closing some of them. the bottom base of the "handle" is open to the bottom of the drum. the top of it will be sealed, so air dont flow in at the top.
