“Truncated Dodecahedron” Wood Model

Posted in 1, geometry, Geometry Models, mid century modern with tags , , , , , , , , , , , , , , , , , , on August 19, 2010 by rndmodelshop

Truncated Dodecahedron all wood model.

The Truncated Dodecahedron is one of the 13 Archimedean Solids.  It has 12 decagons, 20  triangles, 60 vertices and 90 pieces of wood. Each piece is mitered so that they lay on an imaginary plane that passes through the center point.

This was a popular geometric piece during the 1950s – 60s Atomic Age, and was common to see as a hanging light fixture or a table top sculpture.

I make these in pine, then wood stained in fruitwood (light, shown), walnut (dark), cherry (red), or ebony (black). Each piece is signed, then sealed in clear polyurethane.

9″ or 12″ tall

A Cube of 8 Tetrahedron

Posted in 1, geometry, Geometry Models, mid century modern with tags , , , , , , , , , , , , , , , , , , , , , on July 4, 2010 by rndmodelshop

A Cube of 8 TetrahedronTechnically its the same math as a cuboctahedron (8 triangles, 6 squares) but I made 8 tetrahedron in place of the triangles. This is symmetrical on all 6 planes, and it even looks nice standing up on a corner in a tripod stand.

This is typical of a 1950s – 60s Atomic Age ‘Mid Century Modern’ sculpture or light fixture.      9″ square, 48 pieces / Cherry, Walnut, Ebony wood stain or just Clear Polyurethane (shown).

Wood Truncated Cube Model

This is an all wood truncated cube model, clear coated with a semi-gloss polyurethane finish. These can be displayed either on the flat surface or up on the corner for a different look. A couple in different sizes make a nice decor piece.

It has 6 octagons, 8 triangles, 32 vertices and 36 pieces of wood, each angled tword the center point of the piece. As the wood gets older it gets more of a honey color under the polyurethane coat, but I also wood stain depending on what someone prefers. This one is 9″ tall.

Wood Tetrahedron Model “self-dual”

Posted in geometry, Geometry Models, mid century modern with tags , , , , , , , , , , , , , , , , , , , , , , , , , , , , on April 17, 2010 by rndmodelshop

All wood model of 2 Tetrahedrons woven together (aka Stella Octangula), one stained in cherry-wood the other left to a clear coat of polyurethane. These are great gift ideas for math teachers, engineers, students, plus those interested in “Atomic Age” 1950s interior design or Sacred Geometry. 

Most polyhedron have a dual, meaning they share or relate 1:1 with the number of vertices and / or planes. The tetrahedron (4 triangular surfaces, 4 vertices, 6 pieces each) is the only polyhedron that is its own self dual. This particular one I kept 2-tone for clarity, but I also make them in any one color. I have more versions on the website.

Wood Icosahedron Sculpture (woven-1)

This would be very typical of a light fixture in a Googie coffee shop of the 1950s and 60s. It would be easy enough to make with an open bottom or access for a light bulb. Back in the day they may have been plastic. I make these as more of a stand alone geometric art piece. They are clear coated for the photos because you can see cross shadows easier in 2D, but I also stain them to match home or office decor.

Technically, this is an Icosahedron, 20 flat triangular planes, 12 great pentagons and 60 pieces of wood total. Each piece has 2 notches that are compound mitered only halfway thru so they nest together snug like the notches in Lincoln Logs. There are actually very few glue joints in these. This one is 9″ and I also make them 12″ tall.

Wood Cuboctahedron Model

This is an all wood Cuboctahedron. It can be used as a classroom lecture model or a nice “Atomic Age” decor piece. There is a resurgence of Mid Century Modern “Jetsons” type of art pieces lately so these are pretty cool.

This is made of 6 squares, 8 triangles, 12 vertices and 24 pieces of wood. If you look closely, there are 4 true hexagon equators. Each of the vertices has full 3 axis compound miters. This one is 9″ tall.

Plethora of Polyhedron Models and Sculpture

Usually these sculpture pieces are shipping out as quickly as we can make them so it’s not often we get a build up of so many all at once. This made a good group picture for scale. It’s hard to keep at least one of everything here since there are so many different pieces and combinations of pieces. Add in all of the combinations of wood stains and sizes and there are just too many!

When I don’t have a current order I work on new versions, truncations, or duals and various combinations of two or more. It’s really all about the table saw miter and getting all 3 axis angles dead on, then making it repeatable a week, month or a year later without having to re-invent the wheel every time!
