An SCA friend send me a link to an NPR snippet, I sent back the 
following:

You might like:http://www.historicalcarpentry.com/l-art-du-trait.html  
(please don't confuse companonnage with Fremasonry, these are real 
artisans doing real apprenticeships and journeys as journeymen, not 
symbolic/speculative).

Also https://www.handshouse.org/notre-dame-truss for a gift truss,
and https://www.handshouse.org/work#/czech-crane/ for something 
different and period...

For the galoots I will add that handshouse has a stack of galoot 
projects to peruse, and Charpentiers Sans Frontières  who did a project 
that turned into a book with the Mortice and Tenon folks is also in the 
mix.  Site at https://www.charpentiers-sans-frontieres.com/   Notre Dame 
is the top (most recent) of the "Chantiers" section, I was in French but 
they have a lot of banners on the bottom to click for English for those 
who don't.

"L'art du trait" is the process of designing and laying out complex 3-d 
stuff in 2-d and appears to be part of traditional training for 
carpentry as well as stonework.  "companonnage" is the traditional 
journeying of journeymen in France, where they travel the country and 
work, learn, and get Really Neat local things pointed out such that a 
real companon can be distinguished by being aware of certain landmark 
works around the country.  I read a book about it a number of years ago, 
can't remember French or English but do remember the authors being very 
clear "please don't confuse this with freemasonry" with is forbidden by 
the Roman Catholic church for various theological reasons.  Somebody 
from Canada teaches it at Marc Adams.
