【SUMITUKE】Japanese carpenters mark wood with ink-dipped threads and handmade bamboo pens

This time, I took a picture of the girder, beam, and pillar work of the [National Qualification] 2nd grade carpenter skill assignment (trial assignment) that was changed in 2024.
Inking is the process of drawing a core of ink, measuring dimensions and gradients from a full-scale drawing, and writing processing lines.
The core ink is made by making a notch in the wood end with a kebiki and hitting it with an ink pot.
Gradients are measured using a gradient ruler (gradient square) and marked with an ink stick.
I think that the tools are also used in practice, but they are devised and used for exams.
Try using the tips that you can use.
Let's do our best to pass!

芯墨は必要ですよ
側面の芯は少し後ろに振ってあります

質問させてください。動画中で材料に芯墨は打ってますが、芯の印は付けなくていいのでしょうか？

[@daiku-manual]

課題図でついている墨は全部いると思ってください。
なので芯墨は必要です
