Had a little trouble getting the ash drawer out of the firebox mid-smoke last weekend. I couldn't dump the ashes and it worries me a bit with a long smoke planned for the 4th. It seems maybe it expands when it gets hot somehow, and gets stuck about a third of the way out; works fine when cool... I was thinking about bending the top guides up a bit, but not sure if that was the problem. Anyone else had this problem and know how to fix it?
