OK, thanks cj! The front and back of my hoods will have Openings, approx 4-5" high, and about 2.5' long. I'll probably end up with 3 fans exhausting out the top, and 2 on the rear portion where there is still wood. I'm gonna post a new topic in the DIY
forum, so if either of you would add your input here or there about this idea, I'd greatly appreciate it. Oh, and good luck, Electrobes!
