First allow me to apologize for no pics yet. My net connection is acting up, however I will try to post a few pics ASAP. I took a piece of 55 gal. drum and rolled some bands out of gauge material at work so that I could set it onto the base of my 22.5 Weber, and also to get a better fit for the lid. I placed a piece of 3/16 plate onto the original cook grate after raising it up a few inches. I really like the way it performed when I smoked a couple of butts and chicken for mine and my youngest sons B'day the first weekend of October. My question is concerning the plate. It is square and fits the drum corner to corner, leaving the moon shaped sides for heat and smoke to come up. I rather like the idea of this plate for thermal mass, as well as to let the drippings sizzle back up. Is there a real downside to having this plate in place??
