Looking good so far. I like the idea with the tubing and robart hinges. I've a couple of builds where I wished the hinges were longer. Such a simple solution.

"I don't know if any of you guys do this or not but I just had to do a mock assembly to see how it looks put together."

I believe I can say with confidence that every "true" builder has done a mock-up during the build.
