rb, I cant say for sure what is best for your project but I would guess that some sort of notched in bracing would well surpass a nailed in piece. Bracing is primly to stiffen the structure but can also help to break the span of long support beams. I got a ton of help from a timber framing forum over at "The forestryforum dot com" They have an excellent discussion board on timber framing. Additionally check out The "Timber Framers Guild" web site, they have a discussion board as well. Also you may want to invest in this book "Building the Timber Frame House" by Tedd Benson, I would consider that indispensable for what your building. one last web site, Woodweb, everything you ever wanted to know about wood (drying, characteristics, shrinkage etc) Keep you shoulder to the plow, measure twice cut once and don't look to far ahead, just keep focused on what you need to get done today.
