I am new to all this but have a young son who loves it. I built a 10x10 lean to with a steal roof and a crushed limestone floor. A neighbor gave me 8 inch double wall wood stove flue pipe, cap, flashing, and celing support. My first question...do I cut a hole in the steal and screw the flashing to the inside and caulk the heck out of it? My roof is the standard pole barn steel...not flat. It has a 3- 12 pitch. My second question.. Do I build a side draft or a hood. The building is not air tight. The walls are dog ear fence and I lined the inside with left over roof steal around the forge while leaving 25-30 inches from the fire pot to the walls. I thought of using a cut 55 gallon drumb for a hood or a 25-30 gallon drumb for a side draft stack and attaching the double wall pipe to the top,of it. Just looking for advise. Will any of these ideas work?
