From solid cherry block this peace was made on the lathe without splitting or gluing. Tiny dodecahedron inside bigger one and inside the sphere…

Very nice!

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?

hmm…

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.
