Yes Boo, that is the same post and beam tech using large logs from trees as your building matterials. The only difference is in the size of the trees available 500 years ago, and the level of carpentry skills available. Ben Law has mastered the skills needed, a few Amish and some Mennonittes have kept it alive, but for the rest of society it has become a lost art. The mortis and tenden joints are hard to cut by hand, and some of the angles involved are very complicated to visualize and cut correctly. Every thing must be cut to fit together exactly and then be errected. I have not had the opertunity to watch a Barn Raising, but from what I have heard it is awsome. The Amish up in the Mountain have done several in recent years after a tornado went through. The main carpenter in charge pre-cuts all of the beams and joints ahead of time, everything is ready to go. Then the Amish crew arrive early in the morning and start work, by evening the barn it up and standing, with a roof on it and siding. They do not use any power tools, all hand work. The Amish wear black hats in this area, a friend of mine told me when one barn raising was to take place. His comment was " If you want to see Black Hats a working then come on up "
Never doubt that a small group of dedicated people can change the world, indeed it is the only thing that ever has.
