The exhaust port is bored into the bottom board, and comes out to the front. Possibly pointless if you are working with already built materials, but I thought I'd at least share one design that doesn't have the exhaust port in the top of the chest.   The open weave cloth solution doesn't sound bad though...   Frank Vanaman Baltimore, MD
