sometimes i feel that my fires go out bc the splits go flat against the bottom grate and the fire doesnt have space. so i cant see how u can lay 2 splits and pour the coals OVER them. i usually pour the coals and then put 3 splits over the coals. ill try your method next time. does your bottom grate have 2 metal pieces sticking up to lift the splits?
