I have followed the advice I received earlier about my cracked firebox. I aquired a new firebox and have continued using the cracked box which is now in four, large pieces.[p]My concern is that in fitting the pieces together I have two crack openings that measure about 1/8" wide. Can I get an opinion from the forum about whether that is big enough to cause problems with heat that may escape throuogh to the egg itself?[p]As always, thanks for feedback.
