The joinery is not immediately evident from the drawings, when taking joinery into account the geometric lines in the end come out only to approximates in many cases. The method will be to establish certain timbers as primary and have them fit the geometry exactly, and have other secondary timbers fit in as best as they can considering.
Being made of hewn timbers, mill rule is impossible. I will be using a scribe method.
Mill rule and square rule are both American inventions, and to this day a lot of Central European carpenters apparently don't trust a milled timber to be accurate, and as such will still scribe their joints.
Don, historically the carpenters of the remote Swiss villages would have had no association with any sort of guild. Often times there wasn't a formal carpentry trade at all. There would have been those recognized as being master carpenters, and there is much surviving work showing just how masterful they were, but they would often by occupation have been largely farmers. Such was village life in pre-industrial Switzerland. Add to this the fact that as an Anabaptist I would have been forbidden by law from being in the guilds, a practice that survived in the Canton of Bern until very recent times.
The biggest result of the lack of a guild structure among the rural carpenters is the amazing diversity of building techniques, especially true of the Canton of Bern. Building styles can totally change from one valley to the next, because the people in these valleys would have had very little and irregular contact with each other.
In Switzerland there is a very strong tradition of dress as well, but not so much as a way of identifying your trade. Rather they identify themselves with their people, with their village. There is a famous panorama in the city of Thun of that city in the 1800's, I have heard that many local Swiss can look at that picture to this day and tell you what village everyone it it is from based on the way they are dressed.
