  Having worked with wood since I was a kid, and having a fair amount of experience with boats, where scarfs are common and generally in woodworking, I've never heard a scarf describe a joint where the glueing surfaces aren't flat.

  Not a scarf joint by any commonly accepted definition and it has properties that the normal guitar scarf joint doesn't have.

  Oddly I guess reading this definition, a guitar neck joint is not really a scarf joint as the two pieces go in different directions and a scarf is just extending a piece in one direction. oh well.

  In that case, the traditional joint might be a variety of miter joint. The Selmer joint and my joint might be a sort of keyed miter joint but I don't know if there's a more precise term.

  Sorry I didn't totally get your question, but looking at that diagram, while that line shows a diagonal, both the part coming out of the headstock and the receiving "dish" in the neck are curved. It might look like a scarf joint or a blind scarf joint but it is actually something much weirder. I can't say that I've seen it in woodworking too much or what you'd call it properly.

  Right, sort of a cup and cone scarf. I think I've seen this in earliest spanish guitars or lutes?

  The behavior of a scarf joint, is to unify the distributed shear stress at the bond line, while avoiding the eccentricity of a lap or splice joint, and also to maintain a uniform cross section, which is a must on a guitar neck. Id say, its probably still the best joint for hide glue and other vintage glue systems, but with modern glues, different joints are as strong or stronger.

  Thankfully, my Patenotte has a one piece neck..

  It looks like "cup and cone" is a term used in the medical field in reference to joint surgery so he may be borrowing the term from there.

  Whatever it is, it's amazing to me that they were able to back then rig up such seemingly complicated joint to replicate it quickly easily.
