Mike,
The videos show how I did my L-girder years ago. In the last video, pay attention to how he handled where his sections along perpendicular walls meet. That looks like how you could handle yours instead of fanning the cross members like you have. I see you commented on it back in 2014. I have done the same thing. Recently I questioned something, then when someone referred an old topic, there I was and had totally forgotten!
Thanks Dave for the link to that topic!!
