    I bought a nice bookmatched set of flamed maple at a German company called Holz-Faszination
    v-8139_orig.jpg

    Out of a long slab of mahogany I had one piece left to make a body
    It had a faulty control cavity routed out, but there was still enough room for a body next to that big hole
    You can see the drawn pencil line for the correct control cavity on the slab.
    body-blank-ready-to-route_orig.jpg


    First step is the slot for the pickup wire. Free hand routing because it will be covered by a flamed maple top anyway.
    pickup-lead-channel_orig.jpg

    After that I routed the control cavity. I always use MDF templates for routing cavities and such.
    routing-control-cavity_orig.jpg
    control-cavity_7_orig.jpg
    first-routing-done_orig.jpg

    The bookmatched set made nice and square and glued them together.
    bookmatched-maple_orig.jpg


    Also bought a nice piece of ebony for the fretboard at Holz-Faszination.
    Had them cut the fret slots and radius the board. It saves me a lot of time (and swearing)
    fretboard_orig.jpg

    Between the mahogany and the flamed maple there will be a thin veneer of smoked oak as a contrasting line.
    I bought the veneer at Arnhemse Fijnhouthandel.

    Next is the moment the glue the bookmatched maple on. Always a bit stressful because the center line has to be perfectly in the middle.
    I use small nails outside the body outline to secure them so the top won't slide out of place when glued and clamped.
    In this pic you see the template on top (and the flamed maple not yet in place)
    template-on-body-with-veneer_orig.jpg
    clamping-the-top3_orig.jpg


    The cut out the rough shape of the body
    back-of-the-body_orig.jpg
    body-with-top-rough-shape_orig.jpg


    And after that routed along the MDF template
    body-routed_1_orig.jpg
    maple-oak-mahogany-sandwich_orig.jpg


    Also routed the profile for the control plate on the back of the body
    control-cover-routed_orig.jpg


    Over to the fretboard.
    Drew all the inlays and used an awl to make center holes, which will make it easier to drill correctly
    fretboard-punched-drill-holes_orig.jpg


    Wrote the size of the drills to avoid mistakes.
    drilling-the-position-markers_orig.jpg

    Glued in the position dots with super glue
    glueing-in-position-markers_orig.jpg

    The 12th position is made out of short piece of aluminum tube with a black position marker inside.
    gleuing-in-position-markers2_orig.jpg


    After all the inlays were glued in, I sanded with a radiused block.

    Cut the slot for the truss rod access with a jewelers saw.
    position-markers-look-good_orig.jpg


    After sanding with the radiused block I sawed the fret slots the right depth and width.
    sawing-the-fret-slots-to-the-correct-width-and-depth_orig.jpg

    And filed the edges of the fret slots with a triangular file in order to make the fret site in properly.
    filing-a-tiny-angle_orig.jpg

    I cut the fret to the slightly oversized length so I have enough to put them in easily.
    cutting-the-frets_orig.jpg
    frets-ready-to-be-hammered-in_orig.jpg
    hammering-in-the-frets_orig.jpg

    Cut the frets to size and sanded off the sides at an angle.

    frets_orig.jpg

    Back to the body.
    Routed the pickup hole. Since the Alumitone pickup is square I cut the rounded corners with a chisel.

    chiseled-the-corners_orig.jpg
    pickup-fits_2_orig.jpg


    With a raps I made the contouring of the body. And the final steps were done with a scraping steel.

    Drilled the output hole

    Back to the neck.
    I don't have that many pics of the initial steps. So I'm borrowing pics from a previous build with the exact same neck..
    A piece of quarter sawn mahogany. Cut to strips on the saw table of a friend who is a carpenter.
    hals-aan-reepjes_orig.jpg

    The neck is a five -piece laminate of mahogany and American walnut.

    hals-met-fineerstrips-los_orig.jpg
    in-de-lijmklemmen2_orig.jpg
    hals-in-de-lijmklemmen_orig.jpg


    Sawed the headstock angle.
    It's about time I bought a band saw...
    cutting-headstock-angle_orig.jpg


    Routed the truss rod slot.The last part -where the spoke wheel goes- is cut by hand.

    trussrod-channel_orig.jpg


    The headstock also gets a thin veneer of smoked oak in between the five piece neck and the mahogany face plate.

    I glued the fret board (frets included) onto the neck. I always use strips of bicycle tubes tired together for this job. It gives a perfect even pressure without the risk of bending the neck while clamping.
    glueing-the-fretboard_orig.jpg

    The I can starte shaping the neck
    I have a template with four check points: position 0, 5, 9 and 12
    neck-ready-to-shape_orig.jpg
    neck-taking-shape_orig.jpg
    headstock-laminate_orig.jpg


    Before the neck is glued in I made the side dots.
    drilling-side-dot-12_orig.jpg
    drilling-side-dot-12-nr-2_orig.jpg
    side-dot-insert_orig.jpg
    side-dots-sanded-flush_orig.jpg

    And then the fitting of the neck pocket and heel. Endless sanding and shaving.
    fitting-the-neck2_orig.jpg
    heel-and-pocket_orig.jpg

    Checking the neck angle.
    neck-angle-check-2_orig.jpg

    Not yet glued in, but a perfect fit already.
    neck-in-the-pocket2_orig.jpg
    bare-bass_orig.jpg

    Final step before the neck is glued into the pocket is drilling the tuner holes.
    drilling-tuner-holes_orig.jpg

    Drilling some holes into the body

    Glueing the neck into the pocket after one final check.

    After the neck was joined to the body, it was time for the finishing process. Filling the pores.
    pore-filler_orig.jpg


    Taping off the body to stain the top.
    taped-off-back-and-sides_orig.jpg
    first-stain-red_orig.jpg

    Sanded back to accentuate the flame
    sanded-back_orig.jpg

    And finally stained the entire bass in the desired red color.
    staining_orig.jpg
    back-stain_orig.jpg

    After a few layers of clear coat.
    red-stain-back_orig.jpg

    After many thin coats of laquer and lots of sanding it time to dress her up.
    Bridge installed, Pickup in place, strap buttons drilled etc

    Hey, great job! Nice design and beautiful result. :)

    Can you tell me where you got your spoke wheel truss rod? I've been using them in my guitar builds, but I've struggled to find anyone that carries a longer version which would be suitable for bass.

    Thank you. It took me quite a while to find the right ones.
    I prefer the ones where the blue shrink wrap goes around the entire truss rod. Not just around the round rod that turns. With the shrink wrap around the entire truss rod it will never rattle inside the neck.

    I buy them here

    This is a gorgeous bass - you do nice work!
    I have a set of those Lace Alumitones on the shelf to use in a future build sometime. Not sure when or what, but looking forward to throwing them into something one day. You must like them, you had them in your blue bass last year I think...

    Thank you.
    Yes, I'm amazed by how good those Alumitones are. I used to be skeptical about them, thinking they would sound harsh and/or trebly. But they don't. At all. They're dead quiet, and they are well balanced and powerful.

    I first used them in the twelve string bass that I built. I was looking for wide humbuckers with bar magnets to make sure each string would be picked up properly. The Alumitones ticked all the boxes. And I saw some YouTube videos that convinced me.

    After the twelve string bass I decided to use an Alumitone in the EB-N that I built last year (the blue one).
