The wood
you are dealing with is usually called Jatoba or Brazilian cherry. It
doesn't have the mystique of 'rosewood' but changing the name just might
keep the feds off your doorstep.

Now, to your question.


All the other things you had to say aside, and having turned no small
amount of jatoba myself, it is my personal opinion that they would do
just as well to turn domestic apple wood, as far as stability goes.
That may be a _bit_ of an exageration, but only a bit. For its
density and __apparent__ dryness (as opposed to the obvious
oily/dampness of most cocobolo you see, for instance) jatoba is
rediculously unstable and apparently incapable of retaining its
finished shape.

Best bet: either find another, more stable wood or rough turn let dry
or kiln dry or microwave dry and then finish turn. Keeping your
fingers crossed the whole time, of course.

At the risk of offending, it seems to me that there are some pretty
basic things of which you are not aware when it comes to wood and
turning.


Absolutely. But you know, I have a friend in the lumber business who
runs into the same thing. He buys stuff that is supposed to be kiln
dried yet when he gets it indoors -- and even turning stock that is
immediately Anchor-sealed -- he starts losing stock to checking.
Personally, I would find a new buyer. But I digress...

I wish you the best but I think you need some expert advice
somewhere along the line. I'm no expert but I have spent a lot of time
in Belize, southern Mexico and Guatemala buying logs and lumber. If you
want to take this conversation off line, let me know.


Heavens no! Don't take it offline. This is precisely the sort of
thing that helps this newsgroup expand its horizons beyond the latest
tool knockoff or discussions of household cleansers and wood drying.
While probably most turners haven't yet turned a wide range of
exotics, most probably hope to at some point, and it is exactly this
sort of forum that helps people expand their knowledge base and know
what to expect when they do get that opportunity. Nothing more
frustrating than getting all excited about turning your first piece of
cocobolo, making a nice, suction fit box and a week later having to
actually _saw_ the pieces apart because they're so tight together. Or
making a platter out of a nice wide piece of jatoba and a month later
it looks like a Pringles potato chip...
