Learning Scribe Rule
When I was preparing for this trip, I searched high and low for information on timber frame layout, and all I could find was that there are two primary ways: square rule and scribe rule. I know that square rule focuses on the idealized timber within the actual timber and that scribe rule deals with laying out all of the timbers and marking them in relation to one another. I also know that many modern frames use a combination of the two techniques for different components and applications. What I could not find on the internet was anything more useful or detailed than what I've written above, so I was unable to even learn the theory behind these techniques.
Now that I am here, learning some of the fundamentals of scribe rule, I see why that is. This is really difficult stuff to convey in words without being able to physically perform the operations and demonstrate it in real time. I think that a well made video could do wonders for learning the basics, or even more advanced techniques, but you really need to be able to see and hear what is going on for it to make sense.
The main tools we used were a variation on the plumb line and a pair of dividers, as well as a pencil and a small ruler.

Will demonstrating the technique.
