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 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!

Wood Truncated Cube Sculpture (woven)

Posted in 1, geometry, Geometry Models, mid century modern with tags , , , , , , , , , , , , , , , , , , , , , , on April 14, 2010 by rndmodelshop

This is a great Mid Century Modern ‘Atomic Age’ decor piece I made of wood. It has 2 different looks depending on which surface you set it on. It could also be converted into a MCM style hanging lamp.

This is a truncated cube, meaning the 8 cube corners have been ‘clipped off’ leaving 8 triangle surfaces as well as the 6 square surfaces. There are 12 woven rectangle beveled ‘picture frames’ that go all the way around, 4 on each of the 3 axis, 48 pieces of wood all together. I compound miter every glue joint so that its a clean tight seam.

This particular one is 9″ tall which is a good size as a table top art piece. I clear coat the ones in the pics to see the cross shadows easier, but I also wood stain either cherry wood, dark walnut or ebony.

Wood Dodecahedron Sculpture (woven-1)

Posted in geometry, Geometry Models, mid century modern with tags , , , , , , , , , , , , , , , , , , , , , , , on April 13, 2010 by rndmodelshop

This dodecahedron is typical of the Atomic Age ‘Mid Century Modern’ design of the 1950s and 1960s. They were common as Googie light fixtures in 50s and 60s coffeeshops as well as a stand alone table sculpture.

This dodecahedron is made of 60 pieces of wood and it has 20 equilateral triangles woven around each vertex. I cut the notches just halfway thru the wood where 2 pieces intersect so they nest together nice and snug. This particular one is 9″ tall, but I also make them 12″ or larger by request.
