The next installment of my CAD and CAM for luthiery videos is posted. I show you how to make a 3D neck back in this one. I made around 1am, I sound like it, sorry. Video here: http://www.youtube.com/watch?v=Qj6C1Fex1FE
Laying out my Big Muff clone in Rhino. I resized the PCB, it’s even smaller. Exported as PDF and imported into Rhino. I’m glad Rhino plays nice with vector PDFs; for the box, pots, and jacks, I just Google the datasheet, import to Rhino, copy, paste, scale, done.
Trying to figure out how to get these curved fret slots into CamBam. So far, no luck. I’m going to cut these with a tiny .023” end mill, the cutting edge is too short to just cut them straight across. If I can’t get this 3D engraving operation worked out, I’ll just cut them by hand. But I really want to make this work.
Same neck, using Rhino’s ‘environment map’ tool to analyze the surface. This will show any kinks or weird spots. There’s a little kink where the heel meets the neck, pretty sure that’s just an artifact because those two surfaces are not yet joined. I’m using a 1/2” ball end mill for these surfaces, it won’t be there once I cut it.
Another view of the neck I’m working on in Rhino. I’ll export the 3D shapes as a .stl file and the lines and points as a .dxf, then I’ll open them in a CAM program to produce the code that drives the machine.
Modeling a 3D object to look like the real “thing” is completely different from modeling for the end purpose of CNC. Here is a guitar neck I am working on, first time doing it for the purpose of milling it out.
