The morning part is the technique of Korean masters. First of all, it is an explanation of Akamatsu, which is used in palace architecture. In Japan, pine has a strong image of a "bending tree", but Akamatsu used in Korean palaces looks for something that extends straight up filled with annual rings grown in cold regions.

Next is the demonstration of the T-shaped Ruler. The T-shaped Ruler is a tool for inking large parts such as pillars and beams, and is the most commonly used tool for Korean ridges. The T-shaped Ruler is made by the beam according to the diameter of the pillar at each site.

You can also draw straight lines on a round pillar in the T-shaped Ruler. We had our customers actually do it. In the straight line, the ink sashimi is attached to the T ruler, and the left and right half are drawn from the bottom to the center line. It is surprisingly difficult to draw a straight line with a thin line, and requires skill.

Next, how to use the plane. Korean planes were originally pushed and used like China, but now many sites use them like Japan. However, he was taught by the teacher to push and use it. It is said that pulling is more difficult and pressing is less burdensome for the body when using it when pulling and using.

Finally, it is a chisel. The original Korean chisel has no wood pattern and is all made of iron. Akamatsu is hard, so it is better to make everything from iron considering the efficiency of work.

The afternoon part is the skill of Chinese masters. In addition to the lecturer Lee Yeong Lei, Mr. Kuniyoshi Oki of the National Palace Museum also participated.

First of all, look like a log as a side pillar and ink the pillar. He drew the center line, the reference line for the inner roll, the position of the hozo, etc., and also introduced the inking symbols representing each. It is likely that you will make a mistake, such as writing "x" on the valid line and "○" on the invalid line, but it is a rule that carpenters must know.

Next is the demonstration of a saw. The Chinese frame saw can be pulled by two people (actually a larger saw). As for the work attitude, it seems that seniors are still up.

Next, I explained how to make the Hiendaruki in the corner. It is said that a rafter at a symmetrical position on both sides of the corner tree is cut out from one piece. There were many people involved in architectural practice at the venue, and they seemed curious.

This is an introduction of a tree called Kusuki, which was used in Chinese palace architecture. When expanded, the fiber looked like a gold thread, so the participants looked into the loupe in order.

The last is a demonstration of a plane. Chinese planes are used by pushing and using, but in the demonstration, they explained the difference while pushing and pulling.

There were many questions from the venue for each demonstration. Thank you very much to everyone who participated, including the ridge who answered carefully.

At the Nagoya venue, a demonstration by Mitsuo Ogawa (February 15, 2015) is scheduled. This is a unique opportunity to see the unique skills of Japanese masters that are different from China and Korea, so be sure to visit us.
