Bob stepped out for a moment (doing porcelain research I think) so you are stuck with the rest of us answering. There are some plans on the net. Try control and f and at the top of this bbs and look for bbq. I'm sergeant at arms of our local post and we don't have room for a brick one so its a few portable grills on steak night. Wick is the one on this board who has a lot of knowledge and research on that subject as it gets asked at least once a week. As long as you don't get complicated and want one that will heat the building throughout the winter, is self basting, automatic burger flipper, automatic hotdog roller, or automatic cleaning, etc., we can help.
