1.3_press fit curves [S chair_final touch+assembly]


At the stage, the CNC-cut plywood pieces were sanded down, manually processed and assembled in sequence.

Assembly logic labelled in Rhino.

Post-CNC notch cuts using the band-saw. Since the script gave too much of a tolerance, I purposefully left the tips of the notches curving in to maintain tightness around the outer cut-edges.

Assembly started from the top, flatter, section of the chair.

The ribs were fitted from below the curves with the help of a mallet.

At the point, only the end pieces left to snap onto place. They both acts as frame bracings for the whose grid structure.


The T-bone corner cuts look visually pleasing on the finished piece. The different density of ribs along the S-curve formulates regions of various flexibility fitting the movement of one sitting on it; notice the top-back part as being flexible whilst the bottom curve and the cup are tighter.

No listeners Prereq: Permission of instructor ; Yr-1 MArch students who have completed 4.123 only Level: H 9 units Standard A - F Grading Can be repeated for credit Lab Fee: 150 A comprehensive introduction to methods of “making” explored through a wide range of brief but focused exercises. Skills = developing complex geometries from flat components; fine-tuning press fit construction, molding and casting, and making repeatable molds for customization. A two-part workshop, the first half will contextualize contemporary tools and techniques within the trajectories of historical case studies of building, combined with hands on familiarization of tools. The second half will implement the tools of our workshop in the context of Design. Working on group design build process for three MIT 150 FAST installations, students will test and influencing designs through the instrumentality of production. These hands-on design build projects are intended to produce reciprocity between skills and design, making more complete the problems of fabrication. Subject limited to year-one MArch students who have completed core-1 studio. Contact: Nick Gelpi, 9-224, 253-9415, -
