I went through carpenter apprenticeship school way back in the day, and for a while I was a production house framer and, later, a custom home framer. There is a difference between the two. These guys are production framers, and they take the shortcuts that production framers take.
I have not read the book, but I understand from watching the videos that the book is meant to teach first-time homebuilders how to build there own home, which in my view, is a
custom home. In my opinion, production shortcuts should not be used in a custom home.
1. Square cuts are not eye-balled; they are measured and marked with a small square.
2. Overcuts are not made; inside cuts are finished off with a hand saw. Over-cutting weakens the framing member.
3. I believe that floor "decking" should be screwed down and not nailed.
These are just a few of the complaints I have with the videos. Again, I have not read the book, and if I'm missing something I hope y'all will let me know.
