Seeking more sustainable practices? Follow furnituremaker John Wiggers

John Wiggers is a pioneer of eco-conscious furniture. In 2005 John was commissioned by The Furniture Society to write a chapter on sustainability for their studio furniture journal: "Focus on Materials" (ISBN: 0967 100437). The materials used in his "Kidney Shaped Desk" can inform your own sustainable building practices...


How it started


It was a series of connections that led to the Kidney Shaped Desk's creation. From a gallery rep in Miami to a NY party featuring holistic-minded supermodel Christy Turlington (click hear to read more) and world famous designer Vladimir Kagan - never could I have imagined that one day I would be working with this icon to build some of his actual furniture.


My connection to Turlington and Kagan came through a common interest in holistic and sustainable living. After my unforgettable encounter in NY, I actively sought a means of incorporating an underlying mode of sustainability into my woodworking practices and into my surrounding environment. Diana Beresford-Kroeger's extensive knowledge of holistic healing and botany seemed to be the necessary key: the notion of introducing rare and unusual trees to the property surrounding my new woodshop seemed perfect. Diana helped develop a bioplan for what I was intending to create, and over time our discussions evolved into an ever expanding exchange of ideas.


The sustainable materials I used:


The Kidney Shaped desk emerged as I continued to wrestle with the idea of how to meld holistic Ayurvedic principles with sculptural furniture design. Using careful mathematics and sacred geometric proportions based on Feng Shui and Vastu Shastra principles, this desk was also designed to utilize discrete inlays of wood that were ultimately suited to their particular holistic attributes. These include special cuttings of Black Walnut for the drawer pulls, and woods such as Hawthorn and Sassafras inside the pencil drawer, all chosen for their natural holistic and aroma-therapeutic properties.


To finance a protype of the Kidney Shaped Desk desk, I needed a buyer. Fate smiled upon me when Todd Marckese needed a desk for clients with strong holistic beliefs. The design I had been tweaking for almost a year wound up meeting the clients' specifications perfectly. I faxed Todd the drawings and explained in detail the holistic attributes of the various woods I was intending to use as inlay.


Less-common sustainable woods:


The main structure was crafted from FSC certified ply, and laminated with Macassar Ebony veneer. The inset of black Tuscany leather was bordered with a radiating grain pattern of wood that was cut to allow it to cascade like a waterfall down the vertical sides of the apron. The plinths on the legs were satin stainless steel.


Inset into the back of the desk were 3 drawers crafted from solid cherry. These drawers were mounted to the Macassar drawer fronts by means of sliding dovetail construction.


Inside the pencil drawer was a pair of trays made of a wood called Sassafras (Sassafras albidum). Sassafras carries within it an oil based complex of compounds that are naturally saturated within the wood itself – both as a wax and as oil. The oils contained within the Sassafras are released as an aerosol each time the tray is opened and exposed to air.


Hawthorn, a traditional healing wood, makes up a small storage compartment between the trays. It was well known to the ancient Greek herbalists, and records indicate that it has been used in Ayurvedic medicine dating back almost 5,000 years.The benefits of the aroma-therapeutic properties of Hawthorn include stress alleviation and heart strengthening. According to Diana Beresford-Kroeger, Hawthorne promotes an overall feeling of well-being and clear thinking.


When you incorporate these kinds of woods into your projects, you give clients access to traditional holistic health benefits that derive from specially-chosen natural materials and a deeper connection to the environmental source that their furniture comes from.

Tough Going with Follow Me


The Follow Me Tool has been one of the most reliable and effective tools in my design of furniture in SketchUp. After all, I like furniture with turnings and moldings so Follow Me has been frequently used with successful results. So I was surprised recently to run into some difficulty with the tool.
I ran into the problem while working on this Philadelphia Lowboy. The Top has a molded edge, but note the unique curved corners in the front.
Here is a close-up view of the front corner of the Top. I wasn't expecting any difficulty making this shaped edge, so it was quite a shock to see funny results with Follow Me. This set me back several hours as I began to experiment with alternative ways of using Follow Me. I knew that it could be done with a plug-in, but I was stuck on making Follow Me work.

The following are some of the steps I used to finally achieve an acceptable result.
Step 1: Here is a plan view of the Table Top corner along with the profile shape. Using the Arc Tool, I drew over the top of the shape shown with red edges and blue face. The angle at the corner is of course 45 degrees, so I placed an angled guideline with the Protractor.

Step 2: Expecting some difficulty with small facets, I scaled up the size of the corner shapes by a factor of 10. Then I placed the profile shape onto the flat shape as shown below. I selected the Follow Me Tool, clicked on the profile shape, and began to drag my mouse along the front edge.

Step 3: Here I am dragging the mouse along the front edge and watching the profile shape extrude the molding step-by-step. Of course, you can operate the Follow Me Tool differently by selecting the path, then clicking on the profile shape. But in this method, it is more difficult to see how Follow Me works and how the profile moves with respect to the path. Note that the profile always positions itself perpendicular to the path.

Step 4: Here I've completed the Follow Me along the entire front edge across the corner. And you can readily see the problems at the corner. This is caused by the path turning in at the corner so that the profile rotates back on itself.


Step 5: Next I restarted the Follow Me, but this time I used the back edge as the path.

Step 6: Even though there were again problems at the corner, I could see a smooth and proper curved face through the corner. The extra edges were a result of face geometry created within the envelop of the molding shape. So I set out to edit and clean-up this area of the corner.

Step 7: I created a cutting plane at the 45 degree angle. Then I selected all geometry and executed Intersect Selected. After cleaning up with the Eraser, here are the results.

Step 8: Using the Push/Pull Tool, I extended the straight portions of the molded edge.

Step 9: I created one-half of the Top by closing in the top and bottom faces. Then I copied and flipped this half to make the whole Top piece.

I suspect there are easier ways to accomplish this difficult shaping (with Plug-ins), but now I know it can acceptably be done using Follow Me only.
