The Art of Japanese Joinery

Product Information

Asari: The outward flaring angle of certain sawteeth. Asaridashi: A tool for aligning saw teeth at the proper angle. Chisel out diagonally marked portion from C to B. Then make a rip saw kerf at E and finish chiselling out the notch to line F. 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. Bari: Beam. (Hari is the correct pronunciation when alone; bari is correct when following another word.) Any kind of beam, such as a girder, purlin. Hasami: A beam. Hasami bari: Scissor beam. (Hari is the correct pronun¬ ciation when alone; bari is correct when following another word.) Spaced beam.

APPENDIX 4 Ceremonies (1) Architectural ceremony recognizes that building one's own house is one of the major events of one’s life. To some, such an event is impossible, but in this modern age, due to the various loans available, building a house has become a reality for many people. Never¬ theless, it is an experience which cannot easily be repeated. Since building a house is such an important event, it is natural to want everything to go well, so a ceremony is held at the start of construction. Over the ages various Shinto and Buddhist ceremonies have been performed. Here, only the most common ceremonies are described. Working the Wood (4) Make a sloping kerf with a rip saw on both sides: along line G to intersect lines H and I, along line I to intersect lines G and H. Chip away with a chisel the diagonally marked sec¬ tion. H maintenance, or the set of the teeth not being even, right and left. If the sets on both sides are not evenly aligned, the cut will be crooked, favoring the side with the greater set (see Figure 2.24). This may be determined by sighting along the length of the tooth edge or sight¬ ing along the length of the blade. Glossary Eriwa tsuki dotsuki komisen uchi: Pin driven with col¬ larring and with trunk. Collared, haunched, and pinned through mortise and tenon.Used to shave the sides of a groove to widen it, or for finish This plane has a built-in guide and is used to cut a groove into a In reality, it is not much different than how you would create dovetails to join wood. But the complexity of these improves its durability and reduces the chance of it coming apart easily. These days people actually use different colored wood to show off the aesthetically pleasing joints in Japanese joinery. Step by Step Guide to Making Japanese Joinery Yourself

Daisen: Large pin. Daiwa: Support ring, or pedestal ring. Sole plate. Daiwa dome: Pedestal stop. (Tome is the correct pro¬ nunciation when alone; dome is correct when follow¬ ing another word.) Full tenoned tongue and groove Aikugi: Double pointed nails. Amado: Shutters. Amajimai: Weather proofing. Ameosae: Dripboard. Arashiko: A plane used as the primary shaver. Arato: A whetstone made of sandstone. Are kata: Are is a foreign word referring to a dumbbell. Ari: A trapezoid shaped piece. (Dovetail.) Ari hozo: Ant tenon. A dovetail tenon. Arikabe: A type of trim. Ari kake: Hanging of ant shaped piece. A dadoed, half lapped, half blind dovetail with full mortise and tenon. (Ari kaki refers only to the dovetail notch of the whole joint.) Also Ari otoshi. Arikake tsugi: Obliqued surface half lap joint. Ari kata: Ant shape. Butterfly spline. Ari kata sanmai hozo: Ant shaped three tenons. Open or through single dovetail joint. Once the joints are carved, you need to slide the tenon in the mortise and drive a dowel in the small square or dowel hole you carved. Use a hammer to drive it all the way through. Once it is through, use your saw to cut the excess piece and lightly sand it so that it is leveled with the pieces.

All wood things in time

A + B are STOP CUTS across end grain just inside layout 1/16"-1/8" deep. C + D are score lines along grain direction Now mark another square around the small square that you will be carving out. This square will be around three to four times bigger than the smaller square. You will also mark a 45-degree line from the corner of the square to the corner of the wood. This will be needed to cut at this angle using a handsaw. Step 2: Carving out the Dowel Hole One’s own experience must begin to establish the context for work preparations and proce¬ dures. Learning and skill accumulate through experience, soak in by repetition, and become second nature over time. 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. Always make sure your chisels are sharp before working on any project. If they are not sharp they will not be able to carve with efficiency and precision.
