Developing form


The form of the chair was developed through contemporary technologies including Rhinoceros 3D modeling software and computer numeric controlled (CNC) machining, as well as traditional crafts such as upholstery and metal work.

Chair tooling: Five 2"sheets of Polystyrene Low Density foam machined (4 ft x 8 ft) individual sections pieced together and laminated and sanded. The tooling was then coated with the lacquer, followed by a release agent. The last two layers (release agent and wax) enable the fiberglass shell to detach from the tooling after it has cured. The following diagram illustrates the shape of the tooling both when put together and as cut sections. After tooling was assembled,



The only fabrication setback occurred during milling process. Upon lamenting the section cuts I realized the tooling was much too large. In an attempt to better understand my error I came across the following explanation on the  difficulties of envisioning changes in volume.


"Allometry derives from the fact that geometrically a large object has more volume in relation to its surface than a small object; more precisely surface increases by the second power of the linear dimension whereas volume increases the third. In the weightless space of mathematics such a transposition makes no difference but when it occurs in the physical world under the influence of a constant gravitational pull, the difference matters a great deal. To the extent that an increase in volume means an increase in weight and shape is altered when size changes. In the psychological world of perceptual awareness, the constant factor that makes for a similar difference is the disproportion in size between man and his dwelling place. The human animal is relatively small and confined to the ground, and since his locomotion is accordingly slow, he builds for himself environments in which the local developments are small. The shorter the distance from an object , the greater the visual angle, which determines which determines the size of an image received by the eyes. In a constricted environment, therefore, a relatively small part of a building or space fills a large area of the visual field and may be surveyable only if the eyes and the head rove back and forth in scanning motions"
