The Complete Japanese Joinery

Product Information

Since joinery doesn’t cause holes in the material, and it is relatively easy to disassemble. In the spirit of mottainai, pieces of furniture that are no longer useful to their owners can be taken apart and rebuilt into something that is more suitable. Taking apart a chest of drawers to make several small boxes, or a more modern item like a TV stand is entirely possible without destroying the well-aged materials. To determine the koshi haba location (point of tarumi or mukumi), divide the length of the irimoya hafu facia into 5 equal lengths. If the koshi haba is located at % of the length away from the ogami end, the facia will appear strong at the point of tarumi or mukuri. 3. For a sori hafu facia, increase the tarumi slightly. If it is not enough, the curve line will appear straight. 7 Japanese tools and western tools are pretty similar, but they have slight differences to them. For instance, a Japanese Ryoba cuts on the pull stroke compared to the push stroke in a western handsaw. These slight differences make Japanese tools unique to their trade of woodworking. Is Japanese joinery different from western joinery? There are around 30 basic joints used for this purpose and many of which are used in combination. Like the Kanawa-tsugi is a combination of half-blind tenoned, dadoed, and rabbeted scarf joints. Beginner Japanese Joinery Projects According to Kogei Japan, an organization that specializes in traditional crafts officially defined by the Japanese Ministry of Economy, Kyo-sashimono historically focused on producing display cabinets and boxes for ritual tea ceremony ( chanoyu ) utensils. Kyo furniture is marked by a regality and flair that was preferred by the Imperial Court members and societal elites who it was made for during the Muromachi period (1336-1573).

wider than the rough plane. The body should be adjusted as indicated in Figure 2.51. Adjusting the finishing plane. Working the Wood Planing Whether a carpenter can do a good job of planing or not can largely depend on the quality of the board being planed. To plane well, all conditions, including the sharpness of the blade, proper height of support, and the others mentioned previously must be satisfied. Since the care of the blade and body have already been discussed, only the planing itself is explained here. Turn piece over and repeat same procedure until a hole is through from bottom to top in center of mortise. Making the top surface the peak, slope to equal the slope of the crown on the hip rafter. The depth 2-4Joinery refers to both the wooden components of a building, and the techniques used for making those components. The craftsperson who does this is often considered a joiner, as he or she is one who joins pieces of wood together to construct something. Traditional Japanese joinery is made entirely without the use of metal fasteners or adhesives. After the end surfaces are squared, using the ink line mark a line between the two squares on both sides of the piece, as shown in Figure 5.32. Plane the surface up to the lines to make one side of the piece completely square. Repeat this procedure until all sides have been squared. rect the conditioning of the body of a plane. Its blade is set perpendicular to its body, and it scrapes across the grain. It is used to correct any slight warp or twist. Joints are either constructed to only use friction as their main method of holding the pieces together, or with a wooden peg that is hammered in tightly to push the pieces together snuggly. Friction fit joints, like the dovetail joint, are often used to attach pieces at right angles in the construction of boxes or drawers. Joints with wooden pegs are often used in scarf joints to attach two pieces end to end to make a longer piece of wood. However, both types can be used in a huge variety of ways. is the actual depth. The bottom face of the moya beam on the hip rafter sits on a slope equal to that of the hip rafter's crown. In other words, on the edge of the top chord, the notch has the depth 3-4 but at the center line of the top face, it becomes shallow to the depth 1-2. Note: As illustrated, match the actual depth of the moya beam on the slope drawn on the cross section of the hip top chord by using the same method to obtain the slope of the hip rafter crown.

Japanese Wood Joinery Sashimono: The Subtle Art of Japanese Wood Joinery

If you dissect Japanese joinery techniques, you can see how they use techniques similar to dovetail joints and tenon mortise joints. Though it is on a much-advanced scale where the wood just seems to slide into slots and combine like it is one piece. At times it becomes difficult to differentiate two pieces of wood that are joined with Japanese joinery. That is how snug the wood sits together with another. Gegyo (Case 1). Gegyo is an ornamental piece which covers the end of the ridge beam on shrine and temple architecture (except in the shinmyo zukuri style). It is also used on common houses. Gegyo is quite commonly seen on farm houses in the Kinki dis To start off Japanese joinery, you need to practice making the basic joints. However, most of all you will need to improve your skill with the chisels as Japanese joinery mostly depends on carving using chisels and cutting using hand saws. Some of the basic joints that you need to first practice on are the Kigoroshi, Kane-tsugi, Kanawa-tsugi, and lastly the Koshikake-ari-tsugi. Once you master these joints, you can basically move on to more complex ones without trouble. Carpentry is a discipline that elegantly merges form and function. The Japanese woodworking tradition of sashimono —a word derived from monosashi , meaning “woodwork ruler”—is an embodiment of how beautiful that synthesis can be.Cut with a rip saw along line A to intersect line B. Cut with a crosscut saw along line B to intersect line A Kamuri of the hafu facia is 60mm from the hafu board. Kamuri of the roof is 90mm from the hafu board. Woodworking Procedures The pieces are shaped in the following sequences, (1) Select manufactured square lumber. Katsura Rikyū is a complex of buildings surrounded by gardens, with a tea house at the centre. It was built by the ruling class to show of their supreme power even though they were not at the foreground of the government. The building itself is a compound of buildings placed precisely throughout a traditional Japanese garden. Where the layout was planned on what view each room will have and how the building will react with the surrounding environment. Katsura Rikyū was designed and built in a very traditional Japanese style. With the mixing of indoor and outdoor the boundaries of the house disappear.The cabinetry is build into the house and uses the highest craftsmanship and precision with beautiful joinery. Dark woods and light walls push the space to seembigger,the walls and floors disappear from vision. As with most traditional tea houses, the entire construction is done in wood, and uses no nails but only joinery.

The mukuri 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 ogami end. 2. The depth of koshi haba should be 8/00 to w/100 of the length. 3. Mukuri should be '-yi00 to %00 of the length. 4. The depth of ogami should be 1.3 of koshi haba's depth. 5. The depth of kijiri should be 0.9 of koshi haba's depth. \ Paper or cloth wrapping In strong sunshine natural woods will burn and their surfaces will discolor. To prevent this, boards for interior use are wrapped with paper or cloth after they have been cut, planed, and chiselled. This wrapper is later removed when construction is completed. In the case of wall members, it is not removed until mud or plaster has been applied. koya tsuka (end post), for end joint surfaces on a nagekake bari (beam), and for V-slanted connecting surfaces of joints such as the daimochi tsugi, shippasami tsugi, and okkake

As a beginner, the first thing you will want to make is either a toolbox or a step stool. Both of these are easy to make, and can be made using hand tools only. Not to mention it does not involve any complex joints. There are a couple schools of thought in the Japanese carpentry tradition. Though there is a core practice shared by all Japanese carpenters, defined by a vocabulary of tools and joints and a method of working, a carpenter will typically identify with one of four distinct carpentry professions. Miyadaikupractice the construction of Japanese shrines and temples, and are renowned for their use of elaborate wooden joints and the fact that the buildings they construct are frequently found among the world’s longest surviving wooden structures. Teahouse and residential carpenters, known as sukiya-daiku, are famed for their delicate aesthetic constructions using rustic materials. Furniture makers are known as sashimono-shi,and interior finishing carpenters, who build shōji and ranma, are termed tateguya. Though it is rare to find a sashimono-shi or tateguya practising outside of their field, it is not uncommon for a carpentry workshop to work simultaneously as both miyadaiku and sukiyadaiku. Joinery is a technique used in each and every one of these lineages or traditions. Hirokomai facia. The method for cutting lumber to obtain a certain grain (wood selection) (kitori) for the hirokomai facia is usually hira masa (similar to the common quarter sawed cut), but for quality work on the lower roof the method is niho
