My second thought would be to look at cutaway_textures

But beware of the killing note:

POV-Ray will determine which texture(s) to use by doing insidedness
tests on the objects in the difference or intersection. If the
intersection point is inside an object, that object's texture will be
used (and evaluated at the interior point).
If the parent object is a CSG of objects with different textures, then
the textures on overlapping parts will be averaged together.

which means that your wood's parts should be clean (and not just
hidden by another part).
