Just finished one today http://milneweb.com . Havent added any intake/exhaust to it yet. Did get a fire in it to try and dry the wood. Any suggestions? First one I have built. Thinking I need to make it as airtight as possible by sealing up cracks. Kinda figured we will use it on the even days as an outhouse, then on odd days a smokehouse. *;o) Got a bunch of birds to do in about a month, then elk season happens.
