If you were given a nice 80 gallon (vertical) air compressor tank, which way would you build it? Everyone I know is telling me to go Horizontal Reverse Flow but something's telling me to keep it upright, not sure why? I have drawn out a few plans either way and the vertical design appeals to me and seems like it would run more efficiently with the fire box below the cooking chamber. My thoughts are to cut out a small door below for the fire box with a larger door above for the cooking chamber separated with some 1/4in plate steel vented on all sides as a baffle. Standing upright it looks like I could simply use three Weber 22in cooking grates with enough room for a hotel pan at the bottom for water. I'd also fabricate a slide out coal box with ash tray, side vents, and center mounted chimney. I've even toyed with the idea of placing a removable 120v heating element w/temp controller or propane burner for those butts or briskets that take a while. That idea is only there because I've been spoiled with my MES for the last few years which has put out some great food along with my side box mod. Maybe I'll just keep it all fire, not sure, I really want something that puts out some top notch bbq with a nice smoke ring. Any thoughts would be appreciated, I only have the compressor at this point and the desire to turn it into something great. Thanks, Dave!
