    No idea how this board ended up like so but I want to join the pieces and make some necks. Anyone done something similar? Wondering how much overlap/what angle to cut them on. I'm assuming a fretboard glued on top will do more to keep them together than the join, but any advice/experiences welcome.

    The wood is dense, quarter sawn blackwood.....pretty speccy!

    I'd choose the same angle as if you were scarfing a peghead which is about 12 to 17 degrees. I don't think I'd try it myself though unless I didn't have any other wood to use. My philosophy is that all those joints will move and telegraph through the finish. I try to minimize that in my instruments. I'd use the wood for something else like a bookmatched top.

    That wood is so lovely I would keep it for a top as well. However, if you absolutely had to use it for this, you could also consider a different type of joint, like a dovetail or something else. Either way, it's gorgeous wood.

    End grain gluing won't hold. If you have to use it as a neck, move the joint as close the the headstock as possible, and do a scarf joint. That would be a side grain gluing, and it's stronger than the wood if done correctly.

    When I join 2 pieces of wood together to make a bow I use a z-splice or fishtail splice. splicing joints are the only way to join two boards together lengthwise with any sort of strength... and guitar necks are under enormous amounts of tension.

    A z-splice is going to look pretty ugly but it's easy to do. A fishtail (or W-splice) looks a lot better but is more difficult. A template made of graph paper helps. I would just save that piece of wood for something else

    I agree with the others. A multi-faceted joint would be better. I would add some graphite rods the length of the neck to strengthen it too.

    Lot of work involved, I'd find/buy another board.

    Do you have a bandsaw? I would slice a small piece of veneer and use it as a headplate overlay (which would have to be thin and curved on a Tele neck).

    But I would never waste those boards in any attempt to make them longer. neck wood is also a tone wood and even if you somehow found a way to make it stable you'd never have the tone that a real continuous piece of wood would have. Scarf joints on CNC machined Taylor necks still don't affect the area you're proposing.
