I was just using the point of the back door as an angle reference. I did a build mistake when I put the ho;e in the side. I measured the middle from the outside without thinking for a second. On the inside the burner is offset to the back because of the back bricks. At first I was pissed but after thinking about it, it may work out better. If I angle it just a little towards the front I am thinking it may spread out the heat even more. (see how I explain away my mistakes ) I can't make any noise right now because the neighborhood is still asleep but when the sun comes up this thing is going to get finished.
