How to make wooden polyhedra

Chapter 1
At woodworking, the fundamental process primarily possible on a cube is called "chamfering."
Chamfering is possible at various angles.
Another one of the processes possible secondarily is "truncating."
In this chapter, I will how to develop all regular polyhedra and semiregular polyhedra from cubes by combining "chamfering" and "truncating."
