To complete the ball the precision is incredible, how on earth did you do that?

Very cool !!! I assume each panel has 5 (or 6) separate pieces.

Wow! I’d love to see how you “jigged” up the individual pieces for assembly.

I’ve always been fascinated with these. Nice job on the ball. From my calculations:
Hex to Hex joints are cut to 20.9 degrees
Hex to Pentagon are 18.7 degrees
Could anyone confirm?

Great work, your angles look flawless, this is something that I have always wanted to do ever since I saw Malcolm Tibbetts Building an Icosahedron in his book “The Art of Segmented Wood Turning” According to Malcolm, to make a Icosahedron, you need to cut 20- 30degree triangles cut with a blade angle of 20.905 degrees, he goes on to say that assembly of 20 triangles with 30 matching sides and 12 perfectly matched intersections of 5 points is well beyond most peoples ability. He’s right, I am going to have to tune my tablesaw up a lot more, just to think about trying this project. Would you mind if I ask what kind of table saw you are uning? Or are you using a table saw, Miter saw combination?

I agree with the 20.905. From memory, I think the pentagon ishould be lower than 18.7, somewhere between 16-17 degress.

I have a german article where the maker quoted 22.5 for the hexagon and 16.0 for the pentagon. Not sure how he got this to work.

Rance, yes I can confirm your angles, BUT I found petagons always needed adjustment to fit them. no matter how precise you cut them. I think all depends on other factors like the movement of the hexes when you leave them to dry and the change that acured by the thickness of the glue itself. If a tiny mistake here and a tiny mistake there, the result of gluing 32 pieces will be noticeable in the end. It is not easy project.
Sorry Aviad for using your page to communicate with Rance. Thanks.
