Hi, I have a ECB that I have made a few mods to, not much, but have gotten it to work fine. However, I want to go hard core with it for smoking for the Super Bowl and am going to do the mods described at this website: http://www.randyq.addr.com/ecb/ecb.html My only question is, how do you build the charcoal rails described as part of Modification 2? He doesn't go into explaining what he did, or how he built it, unless I completely missed it. What are the charcoal rails and how are they attached to the charcoal grill from the smokey? Thanks in advance for you help!!
