Hi Fusion community, (and especially guitar makers),
I wanted to let you know that I’ve been working on a cool project with our friends at CNC Router Parts. As I said way back in October, in this thread, I had started on this project to design and produce a guitar body with Nathan Skalsky, who is part owner of CNC Router Parts. Rather than my usual modeling projects, which just resulted in a Fusion model, I wanted to approach this with the idea of actually producing a real, physical, playable guitar. Since then, we’ve been busy in design and implementation. Since we both have day jobs, it’s taken us a while, but we are finally at a point where we can declare the project done.
In my past guitar making, I’ve always only done completely flat-slab type designs, because it was relatively easy to cut out the shape on a bandsaw from a flat chunk of wood. But, I’ve always wanted to do a carved top guitar. I realized that the combination of 3D design in Fusion + CNC for manufacturing would give me a powerful way to explore this type of design. We are also working on a hollow-body version, which we think will further illustrate the power of CNC + 3D modeling.
We learned a lot. We made a lot of mistakes along the way: Everything from mis-measurements of the neck and bridge positions and height to tool path errors to simple human mis-communication of who was making which changes in which order. We made lots of test runs using cheap wood, each of which revealed things we hadn’t thought of (for instance, that the mounting screws for the bridge can’t go into the control cavity!). However, we are very happy with the results. The Fusion model, I think, came out pretty cleanly. It is fully parametric, and can withstand customization of the outside shape, the carved top shape, etc., and updates without errors.
Here is the model in Fusion:

I’m hoping to start a discussion here about guitar design and building using Fusion. Feel free to ask any questions, make any comments, etc., and we’ll be happy to respond.

Project Update: I was excited to take one of the guitar's that Jeff and I made to the Bay Area Maker Faire 2016 recently (May 20-22) - the red maple one specifically. People really liked it and seeing how it was made using Fusion 360 with our new Benchtop CNC machine. We happened to be making and giving away ukulele's at our booth as a live production shop demo (Makezine - Milling Ukulele's with CNC Router Parts) however we also had a number of open source and customer projects on display (each with a "making of" video loop).
Guitar shown at 0:20 & 0:35
The minor spoiler here is that this one (right in the picture below) is actually our hollow-body design (great for hardwoods like maple) which we are working towards publishing the sources and how-to videos (simular to what we did for the solid body version in Jeff's post). It was very helpful to have the "un-joined" machined body top-half so people could hold that and see what the inside of the hollow body looks like and compare to the finished result.
Did anyone else in our forum community attend the Bay Area Maker Faire this year and perhaps happen to stop by our booth (CNC Router Parts). Major bonus points if you got one of the ukuleles!

Hey guys! I'm a luthier and I'm slowly getting my Fusion skills up to par. I just wanted to pop in and say hello and thank you for the work you do. I've been enjoying Fusion a lot and I'm excited to eventually use it with a CNC.
Very nice design, @knightroguitars! I like a lot of what you've done - it's a nice blend of old and new ideas. I like the single cutaway, but with the squared-off end. I like the carbon-fiber pickguard, that's a nice touch. And the idea of having the pickup toggle in between the knobs is a unique variation.
The one thing that we ran into with our design was where to put the output jack. If you put it along the edge of the body, then you can't use the CNC machine to make the hole for it. That's why we ended up with it on the front face. This has the downside, though, of needing an L-shaped cord to be practical to play. In retrospect, I might have gone with a stat-type angled jack, maybe even on the back.
Keep us informed of your progress. Nathan and I are planning to do another post sometime soon about our hollow version. It was definitely an interesting variation of the project.

Impressive work Jeff.
I didn't build this, But I made some pretty serious modifications to a 1982 Ibanez Artist AR100 that I bought is as a project guitar.
As purchased.
No hardware. No Electronics. Just beautiful hand made mahogany body, crafted in Japan during the height of the Japanese guitar revolution.
Milled a flat spot for the pocket.
Milled the pocket, added a mahogany riser for the Kahler bridge/whammy, lacquered the finish.
Assembled with Pickups and Bridge.
Close up of the Kahler. I dont use the whammy, but I love the fine tuners.
The final product.
It's hard to see, but it's a blackish lacquer with bronze metal flake. Really highlights the Black chrome on the Kahler.
Not a sunburst. I call it an Eclipse finish.

very nice @mike.mattera! You do nice work. Especially the finish. That is something I struggle with, a lot. How do you get such nice results?

very nice, @Anonymous. That is indeed a nice version of a PRS style body. I like it.

That is a great looking guitar Mike. Really nice finish on it. Is it all mahogany or does it have a maple top? Fender also had Japanese made guitars from that era that were some of the best made guitars they ever built. Keep up the great work!
Very well done! Really nice take on the PRS. Looks like you've gotten a good handle on Fusion.
Keep it up and keep us posted!
Hi All, finally got done working on my test bodies and made the real thing. The help I received on the Forum especially from Daniel Lyall, Peter Doering and Jeff from Liberty Machine was amazing. I couldn't have done it without them. I also want to give thanks to all of the other members who chipped in as I would be remiss if I didn't mention them. I can't believe I was actually able to make this guitar. I've attached picture of the test bodies and the finished body of one of the guitars I'm working on as well as the test body and top for another guitar. I haven't cut this one on my good material yet but will post pictures when I do. I haven't been able to find someone with a good enough band saw to cut the top material to make the bookmatched top.
Thanks to you all for making this such a great learning experience as well as a lot of fun.
That looks fantastic! Please keep updating with pictures as you progress. It's fun to see these come together.
