“Truncated Tetrahedron” wood model

Posted in 1, geometry, Geometry Models with tags , , , , , , , , , , , , , , , , on July 5, 2010 by rndmodelshop

This is an all wood Truncated Tetrahedron, one of the 13 “Archimedes Solids” in polyhedra study.
It’s basically a regular tetrahedron with the 4 tips clipped off evenly so that 4 large hexagons and 4 smaller triangles remain (18 pieces of wood total). I can make these in a cherry (red) walnut (brown) ebony (black) wood stain, or just a clear polyurethane coat (as shown). 9″ or 12″ height.

“Truncated Octahedron” wood model

Wood Truncated Octahedron model, one of the 13 Archimedes Solids

It has 8 hexagons, 6 squares, 24 vertices, 36 pieces of wood, each compound mitered tword the imaginary center point. I make them 9″ or 12″ tall & wood stained in cherrywood, walnut, ebony, or just a clear polyurethane on wood (shown). The lightest are best for classroom, because they show cross shadows on the back pieces batter than darker stain.

Wood Platonic Solids Models set for education & display

These are 9″ tall wood models of the 5 Platonic Solids I make for Math, Astronomy and Physics classroom visual aids. They are all compound mitered on all 3 axis at the vertices for maximum glue strength. They also make great office & home decor pieces. 9″ max on any axis seems to be the best for a 12″ cube box to ship them in. I have alot more geometry pieces on my website. Typically when I set up the saw for each of the compound miters, I make them in batches of 10 or so to keep down all of the set up time involved.

From left: Octahedron, Dodecahedron, Tetrahedron, Icosahedron & Cube. These are just clear polyurethane coated for clarity in the photos, but I also wood stain & clear seal them to match someones home or office decor.
