01 Press Fit

I designed a modular book shelf with two types that can be stacked together. In the first cut-sheet, I forgot to incorporate the cutting radius of the drill bit and realized that I have to put in fillets with 1/8″ radius. For each modules, 11 layers of profile components are held by 8 structure components that hold them together with press-fit connection. Profile components are divided into 4 parts in order to conserve the sheet material.

Joints for the assembly of profile components are puzzle-like that they fit together. Joints in between two different components fit also in the same way but cross each other perpendicularly. Dog-bone fillets are made inside to incorporate the size of 1/4″ diameter drill bit and 1/8″ radius fillets are placed at the entrance of the socket to make the assembly easier.

4.196 Special Problems in Architectural Design Complete Fabrications Nick Gelpi Mon-Fri, Jan 5-7, 10-11, 13-14, 18, 20-21, 24-25, 27-28, 01-04:00pm, 3-402/7-432studio, 1st mtg Wed 1/5 Pre-register on WebSIS and attend first class. 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, -
