I love it when someone (thanks KKrell!) quotes that old taxonomy message of mine. Ah, it brings me back.
Further thoughts of mine . . . first, the lacquer-boxwood-Olwell question is interesting. My boxwood Olwell (see my little pic at left) isn’t lacquered, as far as I can tell. Maybe it is. I haaven’t reacted to it, in any case.
As for cocus: I’ve heard more than one person (woodwindythings makers) say they feel like it’s the most “musical” of timbers. Even tapping a billet makes a musical resonance. And, the timber actually has a little grain to it that you can see, making it visibly more interesting than blackwood. I think it’s a great timber, but I also will agree that a lot of it is psychoacoustic or psychosomatic or psychowhatever. Can I hear a difference between me on a cocus flute and me on a blackwood flute? Yes. Is there? Who knows.
Boxwood flutes are also nice. The warping problem is real, but I don’t feel personally like boxwood is any more delicate than other timbers. A lot of it warps and doesn’t crack. It’s quite porous and is probably the only timber that actually ACTUALLY benefits from being oiled. And, like I’ve suggested before, my own opinion is that it’s Nature’s Hypoallergenic Timber. Find some flamed boxwood (with a distinctive grain) and you’ve got yourself a real looker.
From my own personal (albeit limited) experience, I don’t think there’s any real way to predict who’ll be allergic to cocus and who won’t. I would guess (based solely on the taxonomy and its genetic implications) that if you’ve got a peanut allergy, no rosewood/cocus is safe. But otherwise? I’ve personally got horrible seasonal allergies. I live on steroid nasal spray. But do flutes bother me? No. I’ve even got marked dermatographia (a mild skin quasi-allergic phenomenon) but I could probably wear a cocus . . . well, a cocus shirt and I’d be OK. So who knows?
The other caveat is that I don’t have any way of knowing the incidence of cocus allergy. Anecdotally, it SEEMS common, but that could simply reflect that pasty super-allergic asthmatics spend a lot of time on C&F complaining that they react to thus-and-such. (JOKE, people!) Seriously, who knows. Could be that they’re more vocal. I sure would be if I waited 7 years for a flute that gave me hives. Anecdotally, it seems like many people who work around blackwood/cocus/cocobolo dust (if not all) eventually have trouble tolerating it.
So . . . ? Pick your favorite timber! And, be prepared that cocus or even blackwood COULD make you allergic. Nothing ventured, nothing gained!
