Ok, I have had my CG for about a year and have had some succusful rib smokes. The problem is like listed in the mods section I need to make some type of a mod using expanded metal to the firebox charcoal grate after 4-5 hours I loose temp. Let me start this off by saying I have very little knowledge of alloys and their properties. My problem is I can't find a good source for expanded metal and then I am faced with what type of metal to use steel, stainless or carbon and where can I find it. I don't know how to weld so how would one go about installing rails to lay the expanded metal on? I would figure drilling holes would cause more escapes for heat. I have spent two days going through the mods and while I see what needs to be done I am having a hard time implementing it.
