    Ok boys ... the title reveals another exiting project I have in mind. Although I got the Knarbens' Guitars thread going (where I will post the progress of all current builds in) I decided to open a separate build thread for this guitar as it's something new (to me) in several aspects.

    Sometimes I tend to post mockups, plans, renderings at this stage, but I decided not to anticipate anything. If you don't mind my poor english skills you're welcome to watch and comment this journey. It'll be project #10 on the list.

    Let's shed some light on this subject. So here are the woods I use (most likely) and some more details.

    • lightweight Swamp Ash body (chambered)
    • Ovangkol top (probably with small soundhole)
    • Maple / Wenge neck
    • Wenge fretboard (bound)
    • 635 - 675 mm multiscale
    • MGH brass locking nut.
    • black hardware (except the pickups)
    • ABM single headless bridges
    • quite some contours and bevels ...

    Some time in the shop this forenoon.

    Drew the body shape on the Swamp Ash to cut it out.

    Some lines for the truss rod channel and head break angle.
    You see I left some material in the head area.

    Truss rod channel routed. The wider access area proves it's quite centered.

    Cut the headstock angle today. Came out perfekt :) 18° at the nut and about 11° angle. Did it just as always but slided the two ramps instead of having them parallel. Also roughed in the body shape. Left some more meat around the contour to have a better glueing surface. Just ordered the templates for the body.

    I decided to go with an Ovangkol control cavity cover :) The "head" gets an Ovangkol overlay cut from the top also. Time to part the two necks ...

    Templates came in today :) Now I can really go ahead.

    Marked the body shape and the location of the chambers.
    I'll drill, rout and glue the body later this week when I have time. Probably on the weekend!?

    I have to figure out how to make one of these. I've got a couple gearhead buddies with welding rigs that I've been talking to about it. I've also thought of cobbling something together out of plywood and some threaded rod.

    I don't like gluing tops with clamps. I'm about done with that business...

    I'll use some clamps tomorrow to glue the top, but I want to find a better way for future builds. Anyway I bought some more clamps today ...


    Today I managed to do the soundhole and the chambers.

    Mmh, I think it looks pretty good! Went well I guess ...

    Let's see whether the outer edge of the body contour looks good when I cut it to final size. Tomorrow I will have a look inside the chamber with the soundhole and hopefully it's clean ... And I hope to wire channels aren't filled with glue ^^ but I have to wait a while before I know.

    Removed the clamps today. No glue in the soundhole chamber :)

    Now I will have to go on working to thin the body down by 11 mm and to shape the final body shape.

    Productive forenoon tody.

    • thicknessed the body from 51 to 40 mm • routed the body shape • drilled the neck ferrule holes • drilled the holes for the controls (3way and push/push volume poti) • routed the control cavity :)

    Couldn't be happier with how the top glue joint came out :) Perfect!

    I lack of time to work on the guitars. Saturday forenoon is pretty much the most productive time of the week. Here's what I did in the meantime.

    Placed chamfer and radius edges where I don't shape a bevel/contour by hand and drilled for the jack.

    Finally my pickups arrived! :) A nickel covered Ionizer 7 set. Those are custom ordered which took months ...
