Hi Deb:
I noticed your post about needing information to put together a curriculum on timberframing tools, and barn raisings.
I am not from your area of NA but I do have extensive knowledge dealing with the panning, and construction of many timberframe structures one being a 3 bay English barn early 1800's.
I also have video clips of the raising of the barn with about 40 staff in period costume , I also was involved with the construction in a supervisory position of historic planning and the eventual reconstruction which was spread out over 3 summer seasons.
It is great that your group is working to educate the public, and keep alive parts of history that is slowly fading away,
Good luck,
NH
