    Can't believe that I'm talking about guitar #6 here! The last one came out really awesome.

    Something different this time though. I've been planing this 7 for a while now.
    Actually the typical usage for a 7 really isn't my style of music, but I'd like to try my hands on this one.

    Got (very) few parts and some really unspectacular woods together.
    Since I'm taking a vacation the upcoming week I'll probably get something done.
    Already tapered the CNC slotted fretboard and routed the recess for the body sided truss rod access into the board.
    Pics and more info to follow ...

    Yes! Is this going to be the 7-string model that you posted a while ago? I hope so!

    If you're refering to this one than yes and no.
    It's based on this concept but quite a lot different and more 'standard'.
    Here's a rough model of what I want to do ... it's really not exact.

    Reminds me of an Oni, which is a good thing.

    Mmh, I actually feel bad about that!
    Even though there are significant differences I noticed the similarity, too.
    Actually I tweaked the shapes to this on my own, but I've seen the Oni guitars
    before ... :confused:

    Shouldn't feel bad as long as it's not a direct copy. It's impossible to not take any influence from and other builder. I think it's different enough that Dan wouldn't take offense.

    Let the show begin with some boring pictures ...

    The ingredients. Plain Maple and Alder for the body.
    Rosewood fingerboard (645 mm) and headstock overlay.
    (Not sure about the headstock though, maybe a matching veneer again)

    I'll try a recessed TOM bridge this time (62 mm stringspacing).
    Will mix black and chrome hardware, as I liked the way it looks on my last build.

    Plus one for black and chrome and a recessed tom!

    We think alike!

    This part always scares me! :ohno:
    I'm always really nervous when it comes to gluing ...
    Hope it wasn't too less glue ... not much squeeze out.

    Good to know that somebody else is also really nervous when building. :D

    I'm so nervous about building I haven't touched my build in weeks! Haha your builds ate always top notch, you have nothing to worry about. Interested to see a 7 string build I've never played or heard one for that matter. Good luck!

    This is from sanding ONE fretboard radius ...
    The pads were clean this morning.
    You don't want this stuff in your lungs!

    I could keep posting pics ... but I don't want to bore you ...
    You want to SEE something real, no usual fretboard work, right? Haha.

    Some progress on the body.
    One thing first ... I'm disappointed of the glue joint –
    not much glue on the outside ... I think I spreaded it not careful enough.
    I hope that won't bring me in trouble later.

    I roughed the contours with a handsaw (frame saw) and a Japanese saw.

    For this prototype I was to lazy to build a template for the body shape
    (neither have a jig saw nor anything else really useful atm so it would have
    taken me some time ...). If I had a proper belt or spindle sander I'd go
    from here. Ended up doing this:

    I routed a pass freehand and smoothed the cut with an IWASAKI carving
    file to minimize sanding afterwards. This gives me kind of like a template to
    finish the body shape.

    For the fretboard dot inlays I took measurements off of my Rhino drawing.
    That will hopefully make the dots sit at the right place between the two
    top strings. As the inlays are on the outer edge I drilled some deeper,
    literally pressed the dots in and flooded with superglue.

    I sanded the 12" radius just like on all my previous guitars. Sticked the
    fretboard on a straight granite table with one fence next to it. There's
    some overhang on the outer edge, so I can take off the board easier.
    I'm happy – the radius is straight all the way down and centered.

    Used my 50 cm hardwood block and sanded up to 240 grit.
    After resawing and beveling the fret slots I'll sand with 400 and finally 600 grit.
    Also I'll do the sidedots than ...

    How are those carving files? Do they leave a fairly smooth surface? I have a couple of nice rasps, and a microplane, but there seems to be a big gap between what they can do, and my next option, which is sandpaper. The rasps and microplane take lots of material very easily, but they leave a very rough surface which takes a lot of sanding afterwards.
