How To Cut A Japanese Scarf Joint (Kanawa Tsugi)

  • Published on May 15, 2017
  • It takes a fair bit of time but the process isn't that complicated. Here is how I layout and cut my wood scarf joints.

    On this kind of work I'd try a European style frame saw, instead of the Japanese saw. It's symmetrical, you can use it to cut on both push and pull, can cut through much thicker material, and there's a ton of different blades you can use, usually quite thin, with various tooth shapes and sizes. It allows for a longer stroke, though, making straight smooth cuts easier to achieve, and less tiring.

    suck it up princess? I have dealt with carpenters like this guy most of my life.. they have some talent and for some reason think they are something special.. I usually speak them once and fired them a second time.. even though they are talented and have a good skill they are a disruption and a pain in the butt.. Good carpenters can control there ego's..

    Top shelf, absolutely premium work and skill. I also find some of the videos difficult to watch because of your boasting and large ego. Your skills speak for themselves, and they are top tier, but your manner alone, brings your channel down. I have subscribed and then unsubscribed more than once just for that reason. It catches people wrong, and it is without doubt the single and only down side of your video. If you think about it, the painted tools alone, which most all of us recognize, is because of ego backwash. Thank You man... seriously,... for sharing your GREAT skills with us.

    @Samurai I would like to thank you for the content you share with us. I'm 31 year old with an addiction to prescription opiates but have been clean for almost 5 years. I grew up in construction, my father being a builder and master carpenter like yourself. I used to love work working when younger and into early 20's but was soon left with a bad taste in my mouth due to addiction and working with family. I started watching your videos about 5 months ago and then decided to make a jewelry box and his spice rack for a friend. In doing so and continuing to view your content it has ignited a spark and once thriving passion with me and play the first time in a long time I'm excited for the future and excited for the things that all continue to build to thank you sincerely sir

    Hi, wow what a great video, it looks absolutely beautiful. Hats off to you man.
    Can I ask- the template. Would using one side or only cutting one template be enough or is it necessary to have both and should the height of the template be slightly higher than the beam to account for the saw cuts on the actual beam?
    Also what size is that paring chisel? It’s awesome.
    Finally what brand of tool belt/braces are they?
    Cheers Dan

    So if you were a REAL carpenter you would have plowed out the ledger instead of using joist hangers like the rest of us hacks. Just kidding!It does look though like you need about $8,000 worth of tools to make this joint - correct?

    Very nice work!
    I learned to make this joint while working with Japanese carpenters on Kikai Island, one of the Ryukyu Islands in southern Japan. They built the entire house without metal fasteners of any kind (with the exception of nails for the siding). One day, while I was nailing up said siding, the head carpenter yelled at me: "Hey, what are ya doin'?
    "Huh?" I answered.
    "All the wood," he admonished me, "has to be oriented in the direction it grew, especially the posts, because that's the way gravity was applied to them. The house is stronger that way."
    "How do you know which way it grew?" I asked.
    Stroking a post with his gnarled hand he said, "Just feel it. The grain is smoother in the direction it grew."
    I learned a lot working with those guys.
