Here are some modifications we've made. I'm not handy at all, but my father-in-law is great at everything mechanical. We used steel studs to make the base and drilled some holes in the lid and sealed it off with fiberglass gasket for fireplaces. I don't have the pic yet, but I drilled holes in the coal pan and put a lever on it to adjust the air intake. I've never smoked a thing, but I figure before I start I should do it right.
