I have been reading about these things for over a year now and finally decided it's time to build one. Before I bought any parts I searched my garage, my parents, my grandparents, and my great aunts to see what I could find. The only thing I came up with was a Char-Broil portable kettle grill. For now I'm going to use it instead of a Weber because let's face it, free is always better. I bought an IMUSA pot when Walmart decided to offer free shipping and it fits the lid of the Char-Broil PERFECT. My redneck test for fit I stuck the grill lid on the pot, put it in the back of the truck and drove around on the highway. At 70mph it didn't budge so I'm excited to see how it holds smoke. The pot lid also fits very nicely on the grill so I'm going to attach it to the bottom of my pot. By big question I'm having is what size grates do you use for inside the pot? My C-B grate is to big and I can't tell if I need to order the cooking grate for the Smokey Joe or the charcoal grate for the next size bigger Weber? I've looked through a bunch of old posts and for some reason I can't seem to find the answer to this question.
