I did not test the miter in paper. I have built about two dozen in wood. This is the empircal test. Wood is not forgiving..

discrepencys

Thanks Robert, I understand what you are saying about dividing the dihedral angles. However, I am still perplexed. If you subtract from one Dihedral angle you have to add that to it's matching component. Thus, one side is going to be shorter and the other longer. Thus, the inside radius must change ...

Puzzling discrepency?

I am building polyhedra in wood. To build a Rhombicsidododechedron the square sections the miters alternate between 15.857 and 10.4526 degrees. I have built several dozen of these and set my saw to these angles and it worked great..Dead on the money.. However, I read Magnus Wenninger's book "Spheric...

I use a machinest protractor which can be easily set within 2' of arch. Works great.

CNC machine

I have found a simple solution to build polyhedra in wood. Buy a simple Machinest protractor. These can be accurately set to 2' minutes or arch or 1/30th of a degree. Use this to set a table saw blade. I have done it and it works great. Grissley has a protractor for about $50. Get the one with the d...

I make these from wood. I can send you pictures if you like. I have found using 22 ga. staples on the interior works great.

Thanks, I see the objects you build. What material do you use. How do you cut the angles necessary?

I am experimenting with a product called "Sign Foam" which is "high density polyunrethane. It is perfect for these objects.

Thanks,

Hey, Thanks a bunch for the info. I see in Stella 4-D under the Scale Tab an item for "inradius" but I don't see the "out Radius" There are several tabs underscale. Which would you use ? This week end I was able to build a "Rhombicosidodecahedron". I had good success for a first shot. I made it out ...

Wall Thickness

I am making plutonic objects out of wood. I have had resonalble success. I want to take the objects I make, put them in a wood lathe and turn them into spheres. Does anyone know how to calculate the thickness of the wood before it is turned to achieve a final wall thickness of 1/2"
