Carpenters of Japanese Ancestry in Hawaii Hisao Goto Kazuko
Craft History and the Merging of Tool Traditions: Carpenters of Japanese Ancestry in Hawaii Hisao Goto Kazuko Sinoto Alexander Spoehr For centuries the Japanese have made extensive use of wood as the main raw material in the construction of houses and their furnishings, temples, shrines, and fishing boats. As a wood-worker, the carpenter is one of the most ancient of Japanese specialists. He developed a complex set of skills, a formidable body of technical knowledge, and a strong tradition of craftsmanship to be seen and appreciated in the historic wood structures of contemporary Japan.1 The first objective of this study of carpenters of Japanese ancestry in Hawaii is to throw light on how the ancient Japanese craft of carpentry was transplanted from Japan to a new social, cultural, and economic environment in Hawaii through the immigration of Japanese craftsmen and the subsequent training of their successors born in Hawaii. Despite its importance for the understanding of economic growth and develop- ment, the craft history of Hawaii has not received the attention it deserves. The second objective of the study is more anthropological in nature and is an attempt to analyze how two distinct manual tool traditions, Japanese and Western, met and merged in Hawaii to form a new composite tool tradition. This aspect of the study falls in a larger field dealing with the history of technology and of tool traditions in general. Carpentry today, both in Japan and in the United States, relies heavily on power rather than hand tools. Also, carpenters tend to be specialized, and construction is to a major degree a matter of assembling prefabricated parts. -
Potential of Cross Laminated Timber in Residential Design
POTENTIAL OF CROSS LAMINATED TIMBER IN SINGLE FAMILY RESIDENTIAL CONSTRUCTION by Brad Burback A thesis submitted to the Faculty and the Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Master of Science (Civil and Environmental Engineering). Golden, Colorado Date____________________ Signed: ________________________ Brad Burback Signed: ________________________ Dr. Shiling Pei Thesis Advisor Golden, Colorado Date__________________ Signed: ________________________ Dr. John McCray Department Head of Civil and Environmental Engineering ii ABSTRACT Cross laminated timber (CLT) is a panelized engineered wood product that is gaining popularity in the United States as a structural material for massive timber buildings. CLT is shown to be cost competitive to steel and concrete in large building construction projects, but is seen as uncompetitive for smaller scale projects, especially light frame wood (LFW) residential construction. The purpose of this study is to provide a detailed comparison of the cost to construct a CLT home versus a LFW home to quantify the cost difference between both options in the single family home (SFH) market. Based on a realistic floor plan, three different designs were compared based on cost and construction timeline to determine the realistic cost differences between SFH constructions using LFW or CLT. The final results show that the CLT option results in a 21% increase in total construction cost from the LFW option. While it is difficult to justify this -
The Basic Toolkit
THE BASIC TOOLKIT There is a constant stream of members joining the Guild who are new, or relatively new, to woodworking, and who have little by way of hand tools, but are keen to get started. There are different approaches to this. Firstly there is the saying “Do not sharpen a tool until you need to use it. Do not buy a tool until you need to sharpen it.” On a more practical level, you will want a minimum of tools to get you started. Before cutting a piece of timber, you will need to mark it out. The following will start you off: ♦ A ruler for measuring, such as a 300 mm steel rule, and a tape measure — with readable scales. ♦ A marking knife and a pencil (an HB pencil sharpened to a fine point — a flat carpenter’s pencil is too coarse for fine marking, but may be useful elsewhere). ♦ A marking gauge — this will allow you to scribe a line parallel to an edge. It is not a difficult tool to make, and is a good early project. ♦ A combination square — this enables you to mark square to an edge, and at 45º. We then move on to cutting. For this I would suggest the following: ♦ A tenon saw, or similar backsaw. ♦ A bench hook — this is a simple, but useful accessory, and like the marking gauge, easy to make. ♦ A coping saw, for cutting curves. ♦ A set of four or five bevel-edged chisels. ♦ A mallet for when you need to strike a chisel. Modern chisels with plastic handles are not damaged by striking with a hammer, but a mallet has a larger striking face, reducing the risk of missing and hitting your hand! Making your own mallet would be a good project. -

Assign clean-up duties for the shop. Allow for volunteers first. Jobs include: Foreman, safety glasses, tools, tool room, machines*, benches, floor, sweeping etc. Pass out the Hand Tool Project Schematics and Hand Tool Project Order of Construction. Review the Project’s order of construction. © BITA: A program promoted by California Homebuilding Foundation BUILDING INDUSTRY TECHNOLOGY ACADEMY: YEAR ONE CURRICULUM .
