If its airframe grade, its probably a 6Al/4V (aluminum/vanadium) mix,
which I
would think would be better than the "normal" 3/2.5 mix. BTW, I don't
really
know what I'm talking about... my knowledge of titanium comes from the
bicycle
industry.

It is airframe grade. But there are various specs here, and I am not sure
about the stuff I have. In actual fact, the pieces I have are waste bits
from Airbus fuselage construction etc. It is extremely tough, I already
ruined one WC ( Tungsten carbide), and two ceramic sineter cutters on it.
Need tools with a different cutting angle etc. I will get back to it
after
Christmas. Too busy with other things right now.

Thanks for the input though, any and all info is welcome.

"Machinery's Handbook" used to be an excellent source of information on
machining as well as virtually all other matters mechanical. It's been
twenty years since I used it, and I had no reason to be interested in
titanium at the time, so I have no idea if it will be of any help.....but
it's probably worth a look. Last time I glanced at a copy though, it was
selling for about $80. At any rate, you can find it at:

Scanning the Industrial Press catalog, it looks like they have some other
titles that may be of interest.

Good luck.
