    Nice man! The planning for the contours is looking like it’s going to work out awesome!

    I placed the bridge drilled for hardware today.

    Everything fits!

    And looks good doing it, I think.

    I started working on profiling the neck tonight.

    Then it got dark (and cold) and I had to stop about halfway through. It's coming along well. You can see by the maple that it's a bit lumpy around the middle bits, so I'll get all that trued up tomorrow. I don't generally want it to be arrow straight. I prefer a more parabolic shape.

    It's cold and rainy today, and so since my neck carving buck necessarily protrudes out my garage door, I didn't proceed with the neck today.

    Instead, I worked on the body.

    My primary material-removing tool is this big 17" farrier's rasp:
    078_body_shaping.jpg

    The coarse side (shown above) removes material faster than anything else I've tried, including that damned Shinto rasp. The other side produces a much nicer surface, but still needs some work.


    Once I get it in the rough shape I want, I switch to my StewMac dragon rasps.

    They produce a pretty good finish, but not really sanding/scraping ready. After the dragon rasp, I switch to a bastard file, which is ready for finessing with sanding and scraping.

    But that's for another day. I'm tired.

    So here is how it sits today:

    Killer, I'm a huge fan of bevels all the way around. Looking great.

    Well, I went out and did some work on the neck anyway.

    You can just see the where the scarf joint is glued...

    It's lined up pretty OK though, I think.

    Dam Ash looks so cool when carved and beveled & this is going to look killer with a ceruse finish.

    Needed a new RO sander, so I grabbed this variable speed Bosch.

    I love how the grain runs opposite on the left and right. Sort of a radial symmetry type of thing. Very cool.

    Thanks. It was definitely a deliberate choice. With ash, I prefer those sinusoidal grain lines over the more common M or W orientation.

    So I became worried about the structural integrity of my control cavity.

    082_cavity_kerfing_1.jpg

    The top over the cavity is about 5mm thick, and the edges are heavily beveled. So I worried that there wasn't much meat in the corners, so I took a cue from acoustic guitar builders and made some kerfing.

    https://www.lmii.com/116-kerfing

    Kerfing is used inside acoustic guitars to provide extra gluing surface area--and therefore some strength--at the edges where the top and back glue onto the sides.

    So I made some out of some swamp ash cutoffs:

    083_cavity_kerfing_2.jpg

    And I'm gluing it in.

    084_cavity_kerfing_3.jpg

    It won't go all the way around, and I'm ignoring the areas with the screw 'pillars'. But I hope this will help encourage it to be strong.

    That's just super cool. A nod to traditional luthiery. Love it.

    And that's done.

    Tomorrow I hope to finish profiling the body and radius/fret the fretboard.
