We deal with this issue on a regular basis and have found the bladed wedged scarf a great repair. We have done this repeatedly on standing barns with great success (sometimes we don't peg it until we put pressure back on the post). Another note is orientation, we try to put the scarf opposing lateral forces. We have a photo of one in action on a standing barn that Simon Gnehm did for us under extreme pressure, check our website at
www.trilliumdell.com and look under historic retoration then restoration process.
