Re: Polespear Build - Titanium?
Titanium has some qualities that are interesting to put it mildly, but raw stock cost is pretty high.
In machining Ti, it's really hard on cutting tools, I'd rather cut 17-4 all day than this stuff.
Have your friend do his research on inserts and proper cutting angles for tool wear.
Good luck with build. I stay away from it myself.
