Day 40 : slowest carpenters in the world

I knew it will take time to start, but phew~ it took forever to figure out. Today' s work is just part of gable... Well, at least we figured it out. Our roof will be 12/ 12 which means that go 12 flat and go up 12. So it is 45 degree roof. First, to brain storm, and to visualize little bit better, we made a rafter pattern. This will be after walls, but we need to cut rafter 45 degree angle for both side, and birds-mouth cut that cut out a pocket to sit on 2x6 board. The reason we made the pattern first because this roof will be few inches over from the side on the level of 2nd floor. So to make a gable we need to figure out how long is the smallest stud starts. We figured out this invisible corner point, and made a big 45 45 90 triangle chalk line. Then top plate will be inside of this line. The length of studs will be that between bottom line and angle line minus bottom plate thickness minus thickness of angle 2x6. Thank you for reading this. I know this is hard to read. But maybe you can get the feeling how we were confused. We should've just measure the line we draw. But since we weren't sure that would be perfect straight, tried to calculate the number. Of course we mistook several times, and finally about to succeed one stud, Dick came over again. He told us "just measure with framing square and tape measure". I guess... that's the easiest way. Well we know it now. After 2 and half hours, we only had bottom plate lay on the floor and few chalk lines. It took hours to make this simple triangle... But we did it! We nailed first studs two of them side ways to make the corner stronger.
時間がかかるとは思ってたけど、こんなに頭を悩ますとは。。今日は切妻の一部しか達成できず。最悪なんとか要領をつかみ出せた。私たちの屋根は12/12、これは12進んで12上がる。つまり45度の傾斜の屋根。朝一番でしたことは垂木(屋根を張るための斜めに走る木枠)の型を作ること。これで少し頭を整理、想像しにくかったところをもう少しイメージできるようにする。まあ、これは壁の後になるけれど、垂木の一本一本を両端45度、もう一カ所”鳥の口カット”床に走る2x6の上に座るように小さい三角形を切り出さないといけない。なぜこれを最初にしたかと言うと、この鳥口カットの部分が床の2x6に載り、切妻の三角形の始まる点は床の延長線と垂木の交差点になる。切妻の最初の柱の長さを出すために、ようやくこの見えない頂点を出して、やっとこさ大きな直角二等辺三角形の線を引く。斜めの線の内側に2x6がくるので、柱の長さは底辺と傾斜の間ー下の2x6ー上の2x6の傾斜の幅になる。この説明では多分やったことは伝わってないと思うが混乱状態はわかってもらえるか。垂直がでるか心配だったのでボブの数学の先生脳で計算して全部長さを割り出そうともがく。もちろん何回か測り直し、切り直してようやく最初の短い柱ができようとしていたときに、ディックがまた訪ねてきてくれた。「床に引いた線を直角定規とテープメジャーで測ったらいいんやで」やって。やっぱりそれが一番簡単か。。。2時間半かけてやっと床に板が一枚と何本かの線のみ。いー!この単純な三角形を一個作るのに何時間もかかった。とにかくできたことやしいいことにするか。一番最初の柱は横向きに2枚打ち付けてしっかりとさせる。
First time when you see this 45 roof stands up, it's soooo high and steep! Holy Moly the peak will be 3 feet higher from this!
初めて45度の屋根が立ち上がったのを見ると想像以上に高く険しい。頂点はこれより3フィート高い。えらいこっちゃ!
