Howdy! I just got serious in smokers and am in the process of building a vertical offset smoke house. I was planning on integrating a reverse flow baffle/plate in it but I have a few questions... I'm planning on getting a 1/4 - 1/2" steel plate to put in the bottom of the smokehouse. Where is the best location for the smoke stack / baffle hole when you do a vertical reverse flow? How do you calculate the size of the smoke inlet on the reverse flow plate? My smokehouse is 32"L x 47"H x 35.5"W. My firebox is 30"L x 24"W x 25"H. The opening from my firebox to my smokehouse is 5"W x 29.5"L. I'm planning to put my reverse plate 2" above my inlet. As for hole placement for reverse flow... I haven't a clue other than opposite my smoke inlet from my firebox. I'm planning on using a 10" x 6" wall register for my fresh air intake on the firebox. I was going to mount that center of my firebox. I'm planning on firing my smoker with charcoal and or wood. Any advice is appreciated!
