RE: Exotic Wood
It sure isn't as hard as stone. I'm the turned like plastic guy. It's a great wood, It's amazing in musical instruments because it really doesn't require any finish at all to polish up like marble. Of course you will need some finish for your use, and maybe some heavy silencers.
Quite a few woods are sold by weight it always scares me a little too. It usualy means the piece is so irregular in shape they can't measure it for board feet. And no mater whatever yield you get, your paying for every piece of it.
The main problem with cocobolo, other than the fact the stuff makes you cry like you were sprayed with mace, is that it is a very waxy wood. It's just plain hard to glue, which is hardly a recomendation in a bow wood. Pro bows do blow up from time to time, and the wood can be a factor, though I haven't ever heard that CB is more likely to. These are all problems that are manageable.
