When connecting the B pillar (middle hoop) to the C pillar (rear hoop) using stringers or horizontal bars (which ever you want to call them) in a roll cage should I weld the bars on the bends from one corner to the other or should I weld them on the flat part (very top). I see most people have been welding them from corner to corner (in the middle of the bend). Does this help out in strength when a roll occurs or something? My main concern is that the OD is smaller in the corner due to the bend and I can’t get a snug fit when joined. There is some space because of the change in OD due to the bend. The corners become less then 2". I’m using 2" X 0.120". I added a picture of someones cage which is similiar to the cage im doing now. As you can sey the pilars are connected by tubes in the cornors and that is what im refering to in my question.
