Theory aside, if I wanted to build one of these beasts (a wire spider) how
much tension is usually used to create a good stable setup? I would imagine
something like piano wire would work well, but does it take a lot of
tension to lock the thing in place? How do you go about making sure that
the diagonal holder is centered (and properly offset) - are there assembly
tricks to make this easier since it seems like it would be a lot harder to
adjust the centering once it was all assembled. With solid vanes, if I make
them all the same length, I can pretty much assume a centered diagonal -
and it is easy to adjust the exact center with spacers and such without
worrying about tension issues. Has anyone tried making a wire spider in a 
hoop arrangement that could then be mounted in the tube rather than
building it directly into the tube? Also, isn't there more room for
vibration in such a setup over solid vaned spiders?
