Kanna Project Translations
DISCLAIMER: The amazing video series featured on these pages of my website was published on YouTube by Trace Study. These videos feature prof. Kenji Komatsu from Toyama University teaching about the setting and maintenance of a Japanese plane (kanna). I do not own, nor I claim, any rights on these videos - all copyrights are owned by the respective owners.
Below I have posted a non-literal English translation that I have made, with my wife's help, to better understand prof. Komatsu's teachings. I am publishing these translation for the sole purpose of sharing it with the woodworking community, hoping that this can be of help for other people as well. If you know of any ways to improve this translation, please let me know. Any contribution will be of great help to the whole community.
