That's a really good write up. For what it's worth, here's a clearer photo of the frame I built and a couple of things to keep in mind.
1) You'll want the bar top to be 42" high and the underside to be no lower than about 40" so a standard bar stool fits under it comfortably.
2) Set the height of the long cross-bar to a good level to rest your feet on. I wasn't thinking about that when I built mine, but it has turned out to be really nice to have that bar where it is.
3) I used two short cross-bars on the sides of my bar. I think it adds visual interest, but it complicated the assembly because of the threads. You'll see what I mean if you try it. Things are simpler if you stick to just one cross-bar.
4) Try to select pipe lengths so that you don't have to cut any of the pipe. It's a bit of a puzzle figuring out how the lengths of the pipe and the fittings add up to whatever total distance you're after.
