What’s the difference between a lapped-dovetail scarf joint and dadoed-and-rabbeted scarf joint in the Japanese tradition? In this five-day course, you will learn how to layout, cut, and fit these joints using traditional Japanese techniques. Partly theoretical, and mostly hands-on, this course is designed to teach you basic joinery examples used in traditional residential buildings, often hidden or barely noticeable. This course is perfect for those who wish to delve into the world of Japanese timber framing joints.

In this five-day course, you will be guided through projects to deepen your understanding of Japanese woodworking, sharpening, layout, and joinery. This course includes a group project around simple sawhorse construction to allow for practice at different heights. You will dive into joint replication guided by Emi, and come away with a deeper understanding and respect for the Japanese tradition. 

From Emi: “You will be guided through three traditional, standard construction joints, learning to use traditional hand tools as the course progresses to make them. Initially, I set myself this challenge, guided by my curiosity in my Japanese aunt and great uncle’s carpentry profession in Japan. Making 1:1 joints was the first thing I did to introduce myself and prove to myself and my aunt that I wanted to take this profession further. Whether you join out of curiosity or as a stepping stone into this world of woodworking, the main focus will be on getting the best out of using precision Japanese tools and creating beautiful fitting joinery.” 

For those new to sharpening, there will be a short sharpening course to keep your tools sharp throughout the course. By making 1:1 examples of these joints you will learn marking up, cutting order, and how to get the best precision for a good fit.

If you are familiar with Western tools or ways of working, there may be a step back to go forward, but it will be rewarding. As we explore the Japanese tradition, we will learn different attitudes, ways of working, techniques, and awareness of wood as a living material.
