    Custom Neck

    Give your neck a name! e.g. Bob's 000 13 fret. This is how we'll refer to this specific neck for future orders.

    e.g. 25.34 – this is the actual scale length of your instrument. This parameter is used to calculate the overall length of neck
    The fret where the neck joins the body. Used with other parameters to calculate the length of the neck.
    Please enter a value between 11 and 18.
    Lengthens the fretboard by this amount. Used to allow the nut to sit on the fretboard plane. Use zero if you wish to have your nut on the angled portion of the headstock.
    The Volute is the transition between the neck barrel and the head stock. See photos HERE for examples. The exact volute shape is dependent on several other parameters, particularly the Diamond volute.
    A Smooth 'swooping' blend as shown in the drawing is normally programmed to transition from the barrel of the neck to the headstock. If you wish for there to be an abrupt transition which leaves more material for hand shaping, select 'No'.

    e.g. 1.75. This is also the width of your fretboard at the nut. Birkonium will add 0.040” to this width to allow for more flexibility in blending to the fretboard. Due to the nature of holding the part for machining, width sometimes comes out narrower than specified but never wider.
    This is the fret at which the taper of the neck is specified. Can be a different fret than the join fret. Eg, you may specify the taper at the 12th fret for a 14 fret neck.
    e.g. 2.125. Birkonium will add 0.040” to this width to allow for more flexibility in blending to the fretboard. Due to the nature of holding the part for machining, width sometimes comes out narrower than specified but never wider.
    e.g. 0.6” Thickness of the neck profile at the 1st fret. This is also a parameter that some luthiers add a both of thickness to for further customization in the shop.
    "C" Type is the standard neck profile, "V" type is similar to the M-style V neck.
    The height of the heel measured from fretboard gluing surface to endcap.
    In degrees.
    aka M-Style and G-style.
    This is the length of the small end of the heel
    This is the width of the heel at the small end. Without further customization and an additional charge for tooling, this width must be smaller than the width at the join fret to allow the heel to taper along its height.
    This is the width of the truss rod slot. Leave as is if using a Martin trussrod.
    Defines whether the truss rod adjustment slot exits at the heel or the headstock. Heel or headstock Adjust or Martin style. Martin style has a round bottom and sized to fit a standard Martin Truss rod. Martin style truss rods are available from Birkonium.
    If you wish to cut the tenon yourself, use the Luthier cut tenon option. We can cut partially (about 1/4") into the tenon area for a reference as to where the true end of the neck is not including the tenon.
    Length of the tenon. Enter zero for a butt joint.
    Will you require a heel block or will you use your own.
    Birkonium Stocks Martin™ OEM truss rods in both 14 fret lengths and 12 fret lengths for $14 each. Please let us know if you'd like any

    Custom Fretboard

    Give your neck a name! e.g. Bob's 000 13 fret. This is how we'll refer to this specific neck for future orders.
    This entry determines the fret positions on the fretboard. Stewmac has a good page on common scale lengths on their website here: http://www.stewmac.com/freeinfo/a-scalelength The Stewmac site also has a calculator that uses the same formula that I do.
    Typically .005" deeper than your Fretwire tang depth. Don't forget the "0" before the decimal point - the form won't work without it!

    This is simply the width of the fretboard at the nut end in decimal inches. This varies depending on playing style. e.g. a Martin style 14 fret guitar has a 1.750” nut where a Martin 12 fret has 1-875”.
    This is the fret at which we set the taper of the fretboard. Typically it's the 12th or 14th fret but we can set this at any fret location on the board.
    This is the width of the fretboard at the body join fret in decimal inches. Typically between 2-3/16 to 2-5/16 but again – customizable. This must be equal to or greater than the width at the nut.
    For a flat fretboard, input 12000 as the nut radius. Auto or Select radius will give an essentially flat fretboard.
    I can use two methods to radius the fretboard, one called auto-radius or you may specify the radius at the nut and end of fretboard for a constant radius or a compound radius of your exact specification. Click Here for more info on autoradius (opens a new tab or window).
    This specifies the radius at the end of the fretboard.
    This defines the length of the finished fretboard and also is used for the end radius calculation if you select that.
    This is the thickness of the FB at the crown and is constant down the board. Most stock allows for a 0.250” thickness but a little thinner or thicker can be done. Don't forget the "0" before the decimal point - the form won't work without it!
    Some builders are now including compensation at the nut – this parameter allows you to shift all of the frets toward the nut by a constant number. Use this parameter with caution!
