Several sources say that cocobolo is really toxic, but the other species in
the genus (rosewood, kingwood, tulipwood) don't seem to have such warnings.
Anyone know for sure (not that anything like this is ever for sure...) if
kingwood is or isn't hazardous? I just bored a 2.5" x 2.5" hole in a block.
The dust came off in heavy cloud! Fortunately I had an air filter on, and
it worked so well that almost nothing got on my dust mask. I am going to
turn it next and wonder just how many precautions I have to take; I expect
the turning to be even dustier.
I think anything that comes from South America has to be treated like
it was pressure treated deck material. It has to have a large amount
of nasty in it to withstand all the industrial strength bugs they have,
as well as having the ability to resist molds, fungus, and any other
moisture related maladies that would come up with a lifetime of
constant cyclical monsoons.
I actually talked to a guy that lived in S. America and he told me they
use purpleheart, some poorer people use ipe, and there is another wood
that escapes me that they use for decking, gazebos, etc. They don't
paint or seal it the wood in any way, they just nail it up and go.
I would suit up appropriately.
Kingwood is well known for causing near instant sterility and brain damage.
One small whif and a large man is endangered. The only thing proven to be
more dangerous than drilling into Kingwood is turning Kingwood.
The information I've seen is that it's more or less like poison ivy. The
thing about poison ivy is that there are people who can roll in the stuff
all day long and don't even itch. Then one day they become sensitized and
one touch puts them in the hospital. Sensitizers are annoying that way.
