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).

A Wooden Wheels Clock

A clock made from wooden wheels (using CNC). The clock is operated via wheel number 1 (small wheel on the bottom right) via a step motor controlled by the Arduino controller. The code to operate the controller is available here while the CNC code to cut the wheels (from ~6 mm thick birch plywood, in mm, using 1.5mm diameter tool) is available here.

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 Beech wood.

This second table was made from Mahogany and glass.

Borromean Rings

Three interlocking Borromean Rings. Three different wood types (Oak, Mahogany, and Eucalyptus). Can you envision how this object was made? The image on the right gives a hint ("when you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth", Sherlock Holmes).

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.

Thin wall's lamps

Thin wall's lamps. Left is made of olive tree, right from cypress tree.

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 Menorah 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.

Dithering by curves

Dithering is a process of creating gradual color changes by using a (small) finite set of colors. Herein, we recreate a gray level image of Herzl using random black filled curves over light (birch plywood wood) background. Each pixel in the original image on the left (but low resolution sampled to 30 by 30) is mapped to a black freeform random curve, cut as a hole in a light wood (next to left image). The two right images show a zoom-in on a small portion of the image. Curves were randomly crafted to cover varying percentages of the unit (pixel) square and the proper covering curve was selected based on the gray level of every pixel. These 900 holes where then cut with the aid of CNC.

Porous wiggle vessels

Given the pattern shown on the top left, these concentric wiggly rings were cut using CNC, from a few milimeters thick wooden plate. Then, every second ring was rotated half a cycle of the pattern and all rings were glued toegether. Two such vessels are presented here, from Oak (top) and Mahogany (bottom).


The stock from which the earrings were (2mm thick) sliced is shown 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 rightmost image shows 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... Olive tree.

Another neck formed out of a cross of two (different) E & R letters... First three images on the left show the work in progress. Olive tree.

Menora(t) David

A statue made to look like the Israeli emblem, the Menorah from one view (left bottom image) and the star of david from another direction (middle bottom image), from another... Top two images show the two setups of the CNC stages. Olive tree.

Holding Hand

An attempt to manually carve a hand as a vase holder. Hand is carved out of a Tilia wood.

A Facial Statue

An attempt to manually carve a facial statue. Carved out of an olive tree.

A Statue of a Couple

An attempt to manually carve a statue of a man and a woman. Carved out of an olive tree.

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.

Symbiosis 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 tree.

Wood Turning (and some CNC)

The Vase of Two Hands

A vase being held by two hands. A combination of NC machining and turning. The image on the left shows the NC step. 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 tree.

Segmented turning using a CNC Jig I

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.

Segmented turning using a CNC Jig II

This segmented turning piece (a combination of Mahogany, Beech and Oak) is created by glowing stripes of the different wood type, as can be seen on the left image, only to diagonally cut circular rings out of the plate using a scroll saw and glow them stacked together (twisted) into a conical shape. The images on the right show two different final results.

Wild Chess Board Plate

Turning the plate on the right is the easy part once you have the board on the left. However, can you envision how the board on the left was made? The original credit should go to this movie

High Tea

High tea service using three wild chess board plates as above. Interestingly the wavy holder was made using many strips of veneer glued together using the jig shown on the right.

Hexagonal Segmented Bowl

A bowl turned off hexagonal patterning formed out of three types of wood (Beech, Mahogany, and Oak). The left images shows the glued pieces (note the interior pieces are not as high as the outer ones). The original credit should go to this movie

Plate using puzzle-like tiling

A plate with puzzle-like tiles. All tiles are identical, up to rigid motion (rotation and translation). Tiles are made of Oak and Mahogany wood, cut using CNC (See left image), and alternatingly placed.

An Escher-pattern bowl

A bowl with Escher-style pattern at the bottom. The lizards were cut (using CNC) from a 3mm Populus plywood only to be water-painted, for the brown and red colors. Then, the pieces were re-glued together.

These two images shows the pieces before the gluing, separated (left), and interlocked (right).

A Threaded box with cover

A box with a cover, both with threadings. Left shows the two parts while the right shows the box closed. Indian Rosewood tree.

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

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 tree.

Epoxy Vessels

An attempt to use epoxy in vases. Wood pieces are olive tree.

Thin slots in the shape of david star were made, almost through the depth of the stock (to ensure constant width), only to fill the slots with transparent epoxy. The slots were made using CNC on the left image and final result in the middle. In the right plate, the slots were made on a table saw.

A few more examples of david star semi-regular (mixed triangles and hexagons) pattern. Left shows the part tight and ready for the epoxy. Slots were made on a table saw.
