Got14u,
I appreciate the suggestion but I feel like I have the firebox welded on pretty solid. What you can't see from the pictures is that I welded on the firebox before I installed the inside baffle. This allowed me to put one heavy "pretty" bead on the outside and I applied a couple heavy-duty welds on the inside as well. I feel like this allowed me to keep a professional look on the exterior but beef up things where they can't really be seen. I am, by no stretch of the imagination, a professional welder (haven't even been formally trained). Just picked up bits and pieces on the job, researched online, and practiced when the opportunity presented itself. I knew that if I tried to weld in two passes, what I thought could be done in one, I wouldn't be happy with the way it would look. Thanks for looking out because you are right, there will definitely be some heat/stress on those joints.
