http://www.guitarrasjaen.com/English%20 ... Feder2.htm Jeremy, Fernando does something similar to what you mention when carving archtop top plates. The first question, of course, is brace strength when running perpendicular to the grain. I would think that a thin strip of carbon fiber bonded to the braces after machining might address this issue. Nelson |

I'm sure it would work - it's just a lot of wood to cut out of there! I bet it's still quicker than bending sides, bracing, etc. I've built unbraced carved backs before - they worked out pretty well. No structural issues & they sounded good too. It does add some weight to the guitar. Sounds like a fun project...! Trev |

I did this on a bass and it was HEAVY. Plus as Trev mentions it wastes a lot of wood. |
