Do You know of Richard "****" Babcock? He started TF work with his uncle many years ago and many credit him for the revival of timberframing. He restored many historical barns using the old methods. One of the barns was a German barn with the "swing beam". I believe this is one of the barns he restored and moved to Wolftrap Performing Arts Center. He took apart these old barns, restored them, and re-erected them. Some had continuous plates 50' long. This was all done with block and tackles and ginpoles, no cranes or powered machines.
I had the pleasure of knowing **** but never got a chance to work with him. I did learn how to do traditional layout using a chalkline, divider/compass, and plumb bob. Also how to layout timbers from logs. No squares, tapes, etc needed.
Please update this as you proceed.
I like your scarf joints! I'd a been nice if you could find trees to make those beams continuous for each bent.
**** passed a few years ago.
