    hey guys, I just have a few questions about the neck in general.

    How deep are the channels for the truss rod? I thought it was 1/4", but I could be wrong.

    Also, for the scarf joint, does anyone use biscuits, or are they unnecessary?

    Last, would I be able to use a round over bit on the neck? I want to use it to save some time with the neck shaping, but if I'm off on that idea, I'd love to know.

    Thanks

    Greg

    for the truss rod, it depends on the truss rod you are going to use........Stew Mac Hot rods require 7/16 and their speciality bit to do the channel. Most others like LMI are 3/8 deep.

    Scarf joints do not need a biscuit or other reinforcement as long as the joint is good and the grain orientation is proper, just glue and clamp.

    Roundover....you can use one to knock down the corners along the length, and this could make it easier to shape for you, but it really doesn't save much time over using a surform in the same capacity

    Nothing shreds through rock maple like a good SHARP surform. Does a nice job on Bubinga , Wenge and Purple Heart too.

    I guess I like my surforms a little to much...LMAO

    you might want to take in the purpleheart 1/4"
    the fingerboard is noticeably smaller than the neck width
