For ease in fit up..... insert the FB past the weld seam... the weld seam usually has a backing strip inside the tank that makes fitting up the RF plate very difficult.... cutting and fitting around all those odd shapes etc...
Nice work. How did you come up with the 7" to inset the fire box to the cc? i'm just in the process of my build and i see as lot of fb inserted into the cook chamber, is there any benefit to this? Or does it matter if Fb is on the outside? Im sure The Guru will have some input.........Dave?
