Thanks Jim, I appreciate the responses. I have the English Historic Carpentry book, so I will take a look at that. I will look into getting the other book. Seems like there's no go-to place for all things scarfs. I have been thinking about the raising and how each section will go up, so I will continue to do that for the scarf joints as well. I imagine the rafters to go up one at a time, since they will have the support of both the eve plate and the purlin plate. This should allow me to assemble the rafter scarf on the deck and then raise it. I read a post on TimberFrame HQ that showed rafter scarf located above the purlin plate (unlike a plate scarf which seems preferably located to one side of the post). Is that true for rafter scarfs?
