I have most of that stuff, but i use either the rail or "Special Shapes Company" H-column for my stuff (if i can find it). I also use this steel wire stuff i've found that is a great deal sturdier than the standard copper wire, and i've found some more realistic thicknesses than that i was previously using (which is why i have no new catenary yet, haven't gotten around to it!).
I've been trying to build a couple of the wire spans though, as opposed to the k-brace. I think its a little easier, but just as sturdy. the only problem i've had is that i have to drill through the rail so i can slip the wire through, which anchors it in nicely. the only drill i have small enough for the job is my pinvise, which is not good for my hands, lol! i need to get an adaptor piece for a drill press.
