I spent a bit of time this afternoon googling the search term "shaping titanium" to see what came up. Among the hits I got, I found these two links that provide some general information about this material that might be of interest:
here's what the wiki collective had to say:
http://en.wikipedia.org/wiki/Titanium
lots of info on turning/milling/cutting/drilling here:
http://www.espi-metals.com/tech/machiningtitanium.pdf
I haven't found much information yet on shaping the stuff, but I'll keep looking around. I found lots of suppliers and fabricator/shapers as well, but they didn't seem too keen on sharing their trade secrets on their public websites for some reason!
As Tim mentioned previously, shape memory is a seriously dominant trait of this type of metal, so we can expect a good fight when we try to move it around into meaningful shapes. It's a terrific material for making eyeglasses frames that spring back to their original shape after being mangled up, which I suppose would be a good quality for people who tend to get punched in the face alot, but a poor quality for guys like us who want to do some shaping with it.
I'll post any new links I find that may be of interest. I think I see another ball-cap project on the horizon.
