A dodecahedron would be a good start. Does anyone have any experience with this? If so I would appreciate any information on how to do this.

Thanks and regards,

A rather good place to begin would be

www.Georgehart.com.

There are also a bunch of good text books.

Thanks for the replies,

Chris, I just need to know how to calculate the angle, given the thickness of the material. I can set up the saw. It would seem that if I have the pieces all cut to shape and precisely the same size then cutting a bevel on each edge at the correct angle is what is necessary. Does that not seem right?

Robson Valley: I have looked in books, and online, where I find all sorts of ways to make polyhedra out of paper, plastic straws, playing cards, you name it and it is out there, except how to calculate the angle to cut an X thick piece of plywood or whatever material if I actually want to make one of these things that can be held in my hands.

Also, I sat down and worked it out I think. Took a while to visualize it properly but it seems that if I take the radius of a sphere that would encompass the dodecahedron touching all vertices, and construct an isosceles triangle with that radius number for two sides and the length of any edge of the dedecahedron as the third side, then the angle between the third side and one of the radius sides would be the correct angle to cut the edge keeping in mind that each edge is shared by two hexagons so the actual cutting angle would be the above mentioned angle divided by two and for the angle where vertices meet divide by three.

Does that sound right?

Wood Carving Illustrated magazine is published by Fox Chapel Publications. I'm not a subscriber.

But, I do belong to the Carving Forums in their website. Somebody used a recent issue to carve

a couple of polyhedra. I've seen them on line but can't find them again (some weird thread title).

Without knowing, there might be some treatment of the geometry in that article.

Daud Sutton goes to some length to explain how to expand from the Platonic solids into other shapes.

Found it: WCI magazine #61 and the Complete Beginner's Guide to Whittling for 2013.
