I found tiny hinges for cheap. The Dollar Tree has little balsa wood boxes that have a pair of these miniature brass-plated steel hinges on them. I attached them to the phone stand halves with 2-56 stainless flat head screws (from my collection of random fasteners), which I ended up shortening the length of (because they stuck through too far) and also shaving down the heads of (so the stand would fold all the way closed). Operates nicely with no play - just pure rotation of the hinges.

Nice - thanks for the link. Their prices on solid brass stuff are very good.
