Right now, all I have in the back yard is a charcoaler. This winter, I'd like to create a multi-purpose charcoaler~smoker. I'd like it to be able to do it all--charcoal, smoke, cold smoke, and keep things warm while the smoking grate stays full. I wouldn't be able to charcoal and smoke at the same time. But, I could grill and smoke at the same time if using the bottom fire box. Here is a rough design of what I've got in my head. Dimensions and other features aren't completely formulated in my head....yet. Any ideas or suggestions? Okay all you masters--tell me what's wrong and what's right with the idea.
