Japanese Woodworking S02 E09 Build Window Frames for an Entire House Using Straight Grain Cedar

It is becoming less and less common to build window frames for an entire house from solid wood. I had planned to make a video with the door frame, but it turned out to be longer than expected, so I divided it into two videos. I always have difficulty fitting the sliding glass door frame alone because it is so large. If only I were 5 cm (1.97”) taller, I could easily install it. The frame was only one and a half ken (2.72 m / 8’ 11”), so there was no problem, but if it was two ken (3.64 m / 11’ 11”), it will sink in the middle and be even more difficult to install.
