In 2019 I didn’t make much progress with the guitar at all, mostly because my day job kept me busy for much longer than planned. On top of that I moved both our home and my shop (into one location actually).

So it took until April 2020 that I sprung the CNC machine back to life and continued giving the guitar further shape. Here you can see it working on the neck-body joint:

To properly cut the neck contour I had to go beyond the 2.5D approach and go full 3D. In a move to use more open-source software I opted for FreeCAD (also switch to kicad for PCB design recently).

3D tools have a much steeper learning curve of course, so it took me a while to come up with this first design:

Here’s that section after some manual sanding:

While I started applying this 3D approach to the body as well, I realized that it was way too much work just to give all the edges a 5mm radius, so from there on out I went back to good old files and sand paper.

Here’s how that turned out for a section of the back:

I also applied the manual approach to shape the head-stock. Here’s a picture of its back:

With strings!
