Did you do the cube-in-cube then turn the outer cube?

That is just too cool. I wish I were that good with a lathe. Have you thought about posting a blog on this technique?

Ok, start with a sphere. Chuck it up in the lathe and bore the straight hole through. Do that for half the holes (repositioning the piece so it’s a simple boring operation each time.)

Heck, you could probably remove most of the material (to a “just shy of separating the internal pieces” point) on the lathe with something like a crooked boring bar.

Not only are you a very talented woodworker but you are also a great photographer.

Nice work on both.

Nice!! I am thinking instead of drilling each hole like a square box you turned each one. and kept rotating the blank. Looks like a great bit of practice.

Chris you are right about the technique. Making ball is the easy part. Then mark 12 points on the sphere. The distance between them 0.52xD where D is diameter of the sphere. And then I used router bits in the tailstock. I just add two more pictures to show making of the openings.
