Thanks Will and everybody that has responded to my question. Will you are definitely correct that I am in this to learn as much as possible and looking forward to a great building. I have moved on to the next phase. However I have taken the time to understand and go through the exercise you outlined. I find especially interesting the way that joints that approach a surface at an angle (rafter seats etc.) are affected by timber defects. I have gained an apprectiation of this.
