Wire-to-turnbuckle size

[benz]

I had pegged Hardware Store Guy as unreliable--having been one myself once, and knowing that we just made up whatever we didn't know.....
Brion, I found the table to answer my question in your book, just like you said--perhaps I should read the rest of it. My copy of Skene's doesn't have a lot of the information people keep saying it should, but I guess there's differences between various editions. Bother. There is a handy chart, though, with strengths of various sorts of wire, which leads me to ask: what differentiates aircraft wire from others, and: is it suitable for boat rigging?
If only there were a GasTalk forum for all my propane-related questions....
Thanks!
Ben
