“Rhombicubotahedron” Wood Model

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

All wood Rhombicubotahedron Model

The Rhombicubotahedron is one of the 13 Archimedian Solids. This has 18 squares, 8 triangles, 24 vertices, and 48 pieces of wood. Each of the pieces are compound mitered so each is on an imaginary plane that passes through the center point.

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

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).

4 Axis Stellated Tetrahedron in a Cube

Stellated 4 point Tetrahedron in a Cube displayed diagonal on a stand.

The 4 axis of a Stellated Tetrahedron (below) exactly correspond to 4 of the 8 interior vertices of a typical frame Cube. I just combined the 2 figures into one.  This can be displayed up on its corner, or just flat on a cube surface. It makes a very nice table top geometry sculpture.

The cube is 9″ flat, the entire sculpture is aprox 16″ tall in the stand. Each is made to orderand wood stained in cherry (red) walnut (brown) ebony (black) or natural as shown (clear coat polyurethane) that turns an amber honey color as the wood ages. Cube 12 pieces, tetrahedron 18 pieces, 30 pieces in total (plus stand).

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.

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.
