Making wedges used by Japanese professional carpenters to assemble roof members

This time, I took a picture of the [National Qualification] 1st grade carpenter technician task (trial task) that was changed in 2020, and the work of preparing the bulb plug (wood processing).
The bulbul plugs are cut with a hand saw and then molded into two pieces at the same time with a plane.
The overall thickness can be adjusted later.
Be careful not to injure yourself during processing as the parts are small.
Let's do our best to pass!
