Ok So I am working on the last piece of the puzzle that is the UDS my charcoal basket. What size should it be? I want to build it round, so I am looking for those measurements. I have a 13.5 inch round charcoal grate that I will be mating expanded metal to. but wrapping the expanded metal around that 13.5 grate makes the basket look way to big. so what dimensions is your basket?
