Kama-tsugi is a joinery that connects materials with a straight line.
The joining line may be provided as long as it is within about 300 mm from the core of this post. If you connect it away from the core of the pillar, it will break.
However, since the post has processed parts and mortises, it should be processed slightly off the pillar core so that the missing parts are not concentrated in one place.
This is something you always have to think about when making joinery. Think about where to connect them so that the holes do not overlap and become hollow.
In addition, the processed parts of Joinery have their own meaning.
The part that pulls the material forward.
The part where the twist stops.
The part that receives the load.
It’s a good idea to keep that in mind.

We, Suikoushya, plan to establish a school building in Ile de France in 2022.
This is a project that we want to build with Suikoushya graduates and professional woodworkers. Through this real construction project, Takami would like to pass not only Japanese woodworking techniqs and craftsmanship but also the spirit of the Japanese people involved in making things.
