The Complete Japanese Joinery

Product Information

There are many Japanese joinery joints you can work on if you know their ins and outs. But this article focuses on the ones that will help you start on your journey. For the first one, we will focus on the most simple joint in our opinion, the Kane-tsugi. It is basically a mitre joint in which two pieces of wood are joined by a pin or dowel.

Nice to see the work I have been doing for many years and ignored by people now take any relevance thanks to the successful posts of my friend Dylan-san. Another key difference is that American and European architecture often used nails in circumstances where it would be beneficial to use them, but Japan had very low-quality iron that resulted in brittle nails that rusted easily. This forced Japanese builders to come up with ways of constructing buildings that didn’t use metal components at all. Sumi ink is used, which is indelible once it dries. For marking a surface which will later be exposed, reddish-orange vermillion power or ground charcoal is substituted; these may be washed off after serving their purpose. Of course, there are many more tools on a typical Japanese craft person's workbench, but these three tools are the most important, and most frequently used instruments in Japanese joinery. There is a third tradition of sashimono called Osaka karaki sashimono . This variant hails from cities within the Osaka prefecture. Like Edo and Kyo , it prioritizes attention to detail and and long-lasting construction methods, but differs in that it uses imported woods like ebony and rosewood. According to the Japanese Traditional Aoyama Square art gallery in Tokyo, Osaka karaki sashimono specializes in creating desks, tables, and tea shelves. Different joints of view

Also, once you are done with this joint, you can now try making the other joints, like the Kanawa-tsugi and Koshikake-ari-tsugi. For the latter, however, you need to know how to cut a dovetail with hand tools. What is Special About Japanese Joinery? The Complete Japanese Joinery , a compendium of traditional joints and their schematics, explains how shiho kama tsugi is commonly found at the columns of shrines and temples throughout Japan. This hints at how Japanese joinery techniques have spread throughout the various forms of carpentry in the country, scaled up and down according to each tradition’s needs. Horyu-ji: the oldest wooden building in the world A Word on Machine Tools Power tools are of extreme value to the Japanese carpenter in removing, or hogging out, large quantities of wood. While machine tools can rarely match handwork in versatility and acute precision, much time and labor can be saved by employing them wherever they can be used without decreasing the quality of the work. When hitting the chisel, strike the crown straight and follow the steps shown in Figures 5.19 to 5.21. the roof to which the hafu facia is attached) should have a slope about 5/00 less steep than the rafter slope. This results in a fure sumi corner on the lower roof, as well as the hafu facia's becoming larger and there being more leeway at the end wall.

The basic structure of a planing bench is one planing board and two legs. The legs should match the planing board; if it is a 4x4 then the legs should also be 4x4’s. The width for the bench top will depend on the dimension of the wood that is to be worked on. A shallow angle from end to end of the working surface may be comfortable for some, but care should be taken to ensure that this does not interfere with the workman’s ability to maintain a level, even stroke through the length of the board being planed. A wood stop or even just nails, hammered into the end of the board toward which the plane will be drawn, should be sufficient to hold the board in place while it is being planed. Clamps may be used, but they are seldom necessary. The only apprentice of the late Tsunekazu Nishioka, the descendant of a line of carpenters who oversaw work at Horyu-ji, is a man named Mitsuo Ogawa. In an interview with the Japanese government’s Public Relations Office in 2018, Ogawa remarked on how the carpenters at Horyu-ji had the foresight to choose their timber carefully: This document was uploaded by our user. The uploader already confirmed that they had the permission to publish In Japan, as in North America, there are a number of regional variants within a given species, such as cedar or cypress, each with its own characteristics. A workman should be¬ come familiar with the different woods available which have the features desired for each use. One good way to identify local woods which are suitable for use in wood frame con¬ struction is to visit local heritage buildings. The craftsmen who built them were generally limited in their selection of materials to those available locally, so the woods they used for certain applications, and their joinery methods, can be instructive. Types of wood typically used in constructing Japanese houses are listed in Table 3.1.Determining the slope of the cut lines on the top face. Since the moya beam is set perpendicular to the top chord, this will not be the reverse slope of chogen. It will be the same as the nage Kanawa Tsugi—Blind dadoed, rabbetted and keyed scarf joint. In this joint, the two joined ends are identical. (i) Sumizuke Japanese planes ( kanna) are used to make a piece of wood flat by removing thin flat sheets of the wood by pulling or pushing a blade across it. Japanese planes are similar to western style planes, except that the blade is convex, rather than flat. Japanese planes, like the handsaws, are used in a pulling motion, rather than pushing. This tool is essential to the Japanese craftsperson, some of whom will have over 100 varieties of handplane.

Characteristics off Wood Recycled lumber can be useful, since it has had time to become acclimated after being cut and finished; its behavior under stresses has also been tested. Commonly Used Joints A description of simple and commonly used end joints and right angle joints follows. The tsugite (end joint) is used to extend a piece in its axial direction. Some of the com¬ mon end joints are inro tsugi (half blind mortise and tenon), koshikake tsugi (lapped joint), Sori hafu facia. 1. The location for koshi haba is either at the midpoint of the length or at a point % of the total length from the Once you do this with both pieces of wood, you have to hollow out one square while thinning out the other to create a mortise and tenon. The tenon piece will slide inside the mortise and a dowel will join these both together. To hollow out one of the squares use a chisel to carve it out. As before, carve out a small quantity of material to ensure that it does not split or tear.

Japanese joinery uses the idea of basic mortise and tenon, raises it to another level, and creates very complex joints. These joints are so durable that they do not require the use of nails or glues at all. In fact, some of these joints are so strong that once the pieces are joined, they cannot be taken apart by normal means. Draw markings with precise measurements for every project that you need to work on. Use guides and gauges when necessary. Make kerfs with a rip saw along lines A and F to line G, on both sides of the dovetail. With a crosscut saw, make kerfs on both sides along line G to intersect lines A and F. Chiseling should be completed right up to the drawn line (leaving a thin line on the wood). Those allows small adjustments for clean up and fit.
