Laying up a bridge made from Pauduck...two pieces laminated with carbon fiber, this is for a falcate braced 14 fret OM style body...bottom piece has a clearance pocket milled between saddle slot and bridge pins to save weight....caul is machined from same program, I am just totally amazed how accurate this machine is ..

Its a chinese 6040 machine bought off of ebay...upgraded cables to shielded ones as per advice off of cnc zone..machine has been solid so far, more importantly is software, at this point I am only doing 2.5d machining using vcarve pro from vetric software, which is very powerful and easy to use and worth every penny, albeit a little expensive, obvioulsy a cad program is need to draw out parts but vcarve pro has a simple cad program built in , there is a learning curve but its a fun learning curve. Machine is controlled by Mach 3 software which works great and isn't too expensive. |

When you say not to expensive about how much is not to expensive? Sent from my iPhone using Tapatalk |

Nice inlay. What advantage is there to lay carbon fiber between your two parts? |

using carbon fiber allows for the use of lower density woods to reduce mass, in this case pauduck, thereby increasing volume, the carbon fiber along with carbon fiber between the bridge plate and the soundboard adds stiffness , which is necessary to reduce mass on the soundboard at other places,i.e. the soundboard and braces, this bridge should come in under 20 grams. All this is explained in the Gore and Gilet books. |

All this is explained in the Gore and Gilet books. Yes now I understand. My mistake was viewing it unglued to the top of the guitar. In which case Carbon fiber in the middle would add very little strength. But now I see that there's carbon fiber between the top the underside of your bridge and then another layer in the center of your layup which adds strength through the sandwich effect.
