i have read many post on here about not being able to do this but i have seen on youtube a guy who did just this and it was portable which i thought was a great idea he built it on a pallet it was a 6inch batch box with a 30 gallon barrel and a 55 gallon barrel the 30 gallon was the bell and the 55 gallon was welded to the outside of the 30 gallon which created a
water jacket surrounding the 30 gallon barrel it was an open system and his exit gas temps were 160 to 180 so very efficent he told me the onky problem he had was the pallet he built it on caught on fire because the bricks got too hot can anyone give me the exact dimensions of an 8 inch batch box i know there is a resource for it but id like a picture with it so i can see the crtical dimensions
