General Woodworking (With Some Wood Turning/CNC)

An Oval Table

One can only guess how these legs were made.

A Wall Clock

A wall clock, from mahogany (left) and Oak (right).

Spiral Shelves

The spirals are mostly turning (of a cylinder) on a lathe. If you need hints how the spirals were made on the lathe, consult the two pictures on the right. This table is made from a Beach tree.

This second table was made from mahogany and glass.

Penrose Triangle

Penrose triangle is a very well known so called 'impossible' shape. Try google it. This specific variation of the penrose triangle is part of my "Escher for Real" and ""Beyond Escher for Real" work. The right image shows the NC simulation on NCSim. Beech wood.

These bottom two images show snapshots of the NC process.

David Star from Two Penrose Triangles

Here is a variation of the David star using two intertwined Penrose triangles. The CNC in action is shown on the right. See also ""Beyond Escher for Real". Gaboon wood.

David's Head Relief

NC machining of the head of the David's statue. A relief. See NCSim for the NC simulation image.

The Utah Teapot


As one of the most famous models in computer graphics and geometric modeling, here is a wooden version of the Utah Teapot. Yet another combination of (mostly) CNC (top left), making two half-teapots, and turning on a lathe (top right) the inside. Beech wood.


3D Vasarely style stripes

Victor Vasarely (1906-1997), the `father' of OpArt, produced several pictures in which nearly parallel black stripes on a white background bend and deform locally to produce striking Gestalt 3D effects. Inspired by Vasarely's art, in this work we produce a 3D wood version of two such emblems combined together in 3D, Israel's Menora and the david star, that are coming to life independently, from two different viewing angles. Made off sequoia tree, and combined wood turning and CNC work (left image). Thanks go to Uriel Bareven that helped slicing this stock, from Sequoia.

Earrings

The stock from which the earrings were (2mm thick) sliced is showned below. A combination of Ebony, Padauk, and Beech wood. The Ebony was rounded on a lathe.


Wine Glasses, Cups and Goblets - Wood Turning (and some CNC)

Knot neck's wine glass

The neck in the shape of a simple (not a) knot. The NC process is also depicted below. Olive tree.


Knotted Wine Glass

A wine glass with a knotted neck. The image on the right shows the NC step. Olive Tree.

Shoe Knots

Yet another combination of (very delicate) NC machining and turning.

This image shows the NC step. Indian rosewood tree.

Complex knot neck's vases

This time the neck in the shape of a more complex knot (so much so that I decided not to disconnect two joins if you can see them). The left is from olive tree and the right in Indian Rosewood. The NC process is also depicted below.


Bow Tie Wine Glass

A gentleman wine glass with a Bow Tie. The righmost image show another variant. Olive Tree. The images below shows the steps (left to right): the turning, preparation for CNC, and the CNC itself.


Lettered Necks' Goblet

A neck formed out of a cross of two (same) letters...

Siamese Twin Wine glasses

One can turn one captured ring on a wine glass. One can turn two captured rings on a wine glass. But can one turn two wine glasses captured in a single ring? It is doable but the version you see here is only a partial proof - the ring here broke in the process and was glued back in... The three images below give you some hints how it can be done (wood turning only and no CNC).


Anti-twin Wine glasses

Anti-twins wine glasses. Olive Tree.

David Star Cup I

NC machining was used to cut the David Star shape at the neck. The rest is regular wood turning. The image on the right shows the NC setup. The David Star is actually formed out of two intertwined Penrose triangles. See also ""Beyond Escher for Real". Indian rosewood.

David Star Cup II

Here is another variation of this model, this time from an Olive tree.

Symbiosys of the Jewish David Star and the Islamic Crescent Moon Symbols

Here is another variation of the david Star. Herein, the Jewish David Star is shaped to look like the Islamic Crescent Moon symbol from the side. As a result, this model presents the Jewish David Star from one view and the islamic Crescent Moon from another. The image on the right shows the CNC stage. Indian rosewood.

Wood Turning (and some CNC)

Top David Star bowls

Three examples of bowls with a top david star curved out. Top row shows the final piecese while bottom row shows snapshots of the CNC in action. Indian rosewood and eucalyptus.

Top heart spherical bowl

An example of a spherical bowl with a heart outline on the top. On the left is a snapshot of the CNC in action. Indian rosewood.

Wood Chains

Examples of small wooden buckets with wooden chains, built from one wood block (Indian rosewood). The image on the right depicts the CNC step. Indian rosewood.

Candle Sticks

A combination of NC machining and turning. The image second from the right shows the NC setup while the right image shows the final NC part before turning. Beech wood.

More combinations of NC machining and turning.

These images show the NC setup. Olive tree.

The Vase of the Hands

A vase being held by two hands. A combination of NC machining and turning. The image on the right shows the NC step. Olive tree. The geometry was creating by deforming a 3D model of a hand using a geometric modeling technique called freeform deformation, that uses trivariate splines. Olive Tree.

Wicker style Vessels

Wicker style tops for wood (olive tree) vessels. The left image shows the CNC stage.

2 Cones

Two cones turned on a lathe, sliced and glued together... Indian rosewood.

Segmented turning using a CNC Jig

This segmented turning piece (a combination of Mahogany and Oak) is created one layer after another, using a Jig that divides the entire circle to 24 parts. The Jig is made of simple 24 170mm radius lines (12 340mm diameter lines) equally spaced around the circle. You can find the CNC G-code for this one here (the cuts are done in 4 mm deep zigzag motion in Z to a total depth of 8 mm). Note the dividers in the Jig can be taken out to create a division of the circle to 12 (as is the case for the first layer in the final piece), 6, 4, or 3 parts.

Some Bowls





Banana holes. Image below shows the CNC in action. Indian rosewood.




Diamond holes. Left image shows the CNC in action. Indian rosewood.


A Bowl with winged holes. Left image shows the CNC in action. Indian rosewood.


Another Bowl with winged corner holes. Image below shows the CNC in action. Indian rosewood.




Same Vases

Indian Rosewood

Shoe knots, with real shoe laces...


Another combination of turning and NC machining. Carefully inspect the cross sections! The image on the right shows the CNC process. Indian rosewood.


Yet another combination of turning and NC machining, of a vase and its cover. The images on the right shows the CNC process. Indian rosewood.
