    - 35" scale bass
    - 5 string 2 3/4" string spacing
    - 1 3/4" nut width
    - double octave fretless neck

    how wide should the fingerboard be at the end?

    My 5's are 3" at the 24th fret. That works well with .75" spacing at the bridge.

    .75" spacing on 5 strings makes 3" string spacing. Mine will be 2 3/4"

    Assuming that by 2 3/4", you mean at the bridge, and you are asking what your width should be at the 24th marker, on my basses the 24th is generally around 1/8" wider than the bridge spacing. This is in order to leave 1/8" of play on either side of the fingerboard beyond the strings. Still, to be sure you might want to work out the geometry on a piece of paper.

    hey Matt,
    on your neck thru's do you use a straight neck blank or do you let the triangle run out to the end of the body ?

    I am thinking of letting it run out on mine, so the neck gets progressively wider as it goes thru the body.

    any thoughts on this ?

    Most of the time my necks are square through the body section. I generally only taper the body section when I am asked to.

    I build most of my necks just a bit wider than wide enough. I try to be as efficient with the wood as possible. If you want to taper yours, you'll need to either taper one (or more) of the laminates before glue up (this makes lots of things more difficult later on), or you'll need to glue up a blank that is a good amount wider than your finished string spacing, and taper it just before you glue the wings on.

    Most luthiers use a straight neck blank. I believe Ken Smith does a taper, though.

    I've only built one NT bass and used a taper just because I thought it was more logical to extend the neck taper all the way down...

    I was surfing today on various sites listed in the BunnyBass luthiers directory and saw a picture of a bass with what I would call a "reverse NT taper" :D

    The body part of the NT was reducing from the neck to body joint towards the bridge!!!

    First time I see that kind of construction.
