    Default Stewmac Concert

    Here is my 5th ukulele build: a Stewmac Concert

    I am using this build to improve my inlay and binding skills, and to work on correcting mistakes made in previous builds.

    Here is the plan:
    - add ebony fretboard and headstock overlay
    - fabricate bridge from a block of ebony
    - MOP trapezoid inlays on fretboard @ frets 3, 5, 7, 9, 12, 15, and 17
    - gloss nitro black finish on top
    - dark brown mahogany stain on sides and back
    - cream bindings throughout
    - MOP "S" inlay on headstock

    This build is inspired by a 'black top' 'R7' Les Paul that I used to own:

    Build #3 Stewmac baritone (I messed up the neck angle so rebuilding it)
    Build #4 Stewmac solid koa tenor (in progress)
    Build #5 Stewmac concert (in progress)

    Top bracing is different from what is shown in the SM plan. There was a thread about Stewmac concert bracing issues.

    Now on to the inlay. I first created a scale drawing and printed it out to use as templates.

    Trapezoids!


    Original walnut fretboard will be used to practice before cutting into the nice ebony fretboard (from LMI).

    Starting to route the ebony fretboard for inlays:


    One down. Six to go.


    I devised a simple jig to route the straight lines:


    Done routing the ebony fretboard inlays. Needs a little more work to get some of the inlays to seat deeper in the cavities. And I chipped the corner of one piece (hard to see in this pic), so I need to cut a replacement for that one.

    Finished the fretboard inlays today. I was really surprised how well the ebony dust + super glue hides the mistakes. But I think there is some sandpaper grit that got into the gap on 12th fret inlay - I want to fix that.

    Another lesson learned: dust from sanding ebony is not suitable for filling inlay gaps because there probably is some sanding grit in the dust.

    I slipped when cutting the inlay route on the 17th fret. To fix that, I used scalpels to extend the gouge to the fretboard, made it deeper, and carved a tiny piece of matching ebony to fit.
