Lignum vitae

I just bought a few b.f. of shorts from Lee Valley's warehouse sale.

The wood seems covered with wax, though now that I read a bit on the
internet it appears this may actually be oil from the wood...or not.

Can I plane this wood on my [DW 734]? will the surface wax/oil gum up my
knives?

It looks like it may only be good for turning - or can I dress it and use it
as an accent with other woods (maple or birch)?

As others said (more or less), it is wood: use it like any other wood.
It is the world's *heaviest* wood though. Also, don't be surprised if
it turns sky blue when you finish it. Or a bilious green. The color
is only temporary and after a day or two it will change to a nice
brown.

Howdy,

It is likely that the material you see is wax... (that is,
not from the wood.)

I have often seen pieces that were dipped in wax for a few
inches on each end to decrease the chance of checking. I
would guess that Lee Valley, or their supplier, just went
wild with the wax.

It would certainly seem to me that you could dress it and
use it in any way you might want, though I personally have
not used it that way.

All the best,

Bowl blanks are often dipped in wax.

The middle box here
http://www.flickr.com/photos/39383723@N00/336793880/in/set-72157594445381450/
is lignum vitae. Planes fine--do a _lot_ of it and you'll dull steel
knives but a short or three should be no problem. While it's oily,
it's not _that_ oily, what you see on the surface is wax. The natural
oil is a pretty good lubricant which is why the Navy uses it for the
shaft bearings on aircraft carriers. You can use it as an accent, but
I'd advise using an epoxy rather than a PVA glue, and bond the
surfaces fresh-cut.

Stuff will polish to a near-mirror finish using just its natural oil.

It *is* covered in wax. This is to prevent splits and checking.

Sure, go ahead and plane it. I got a small piece once and it planed
just fine. Definitely pay attention to grain direction or you'll get
plenty of tear out.
