There's a book called "Wonders in Wood" by Edwin M. Wyatt that talks
about carving nexted spheres. It doesn't get into too much detail,
basically turn a sphere, do some drilling to get started, then finish
the sphere inside with sharp stuff :-)

This book is small, cheap $9 at Barnse and Noble, (I just bought my
copy last week), and has a bunch of other neat wooden puzzles and
stuff.

Looking for tips to carve nested spheres in wood, probably no more than two
or three spheres. Any ideas or leads?
