In this instructable I will show you how I made the bridge base for my carbon fiber acoustic guitar
using the ShopBot CNC machine and software available at Techshop.
I designed the bridge based on the signature bridge of Bashkin Guitars
, with some small modifications. I copied the bridge slot and pinhole layout from another student in my workshop. I've included the .STL 3D model of my bridge, as well as a 2D tracing of the shape in the photos.
You definitely don't need access to a CNC machine to make a nice bridge. I've found many discussions online about how to make bridges with hand tools and traditional routers. There are also many good books detailing the traditional process of building a guitar, including bridge construction. One book I found at my local library that helped me understand and install the bridge was Build Your Own Acoustic Guitar
- by Jonathan Kinkead.
Before I get started, I want to say that I am NOT an expert luthier (stringed instrument maker). I tried my best to do my own research, but only time will tell if I was successful. If you choose to make your own guitar, please do your own research using professional guides. There are amateur luthier communities online, as well as good books, such as the one I mentioned above.
