sorry, i didnt get a chance to finish… i guess i misunderstood how queue worked. im still a tumblr newb.
i dont build acoustic guitars for a living or anything, but i do know a thing or two about their construction, so hopefully this helps. so as you probably know, the soundboard, or top of an acoustic guitar has the most to do with the sound (or timbre), and volume of the guitar when a note is plucked or a chord is strummed. thats because what your hearing is the vibrations of the strings transfering their energy to the soundboard, which causes the soundboard to vibrate as well. so it is quite important that the top stays flexible. i didnt know a whole lot about carbon fiber acoustic guitars specifically, so i did a little research…
these dudes at rainsong have decided the best sounding carbon fiber acoustic has a bracless soundboard. this makes sense to me as the top is totally free to resonate without any braces to hinder it. BUT, it sounds like making a carbon fiber top that is sturdy and doesnt curl like the problem you are having is quite hard… it took rainsong a couple years to figure out how to do it. and streangthening a soundboard isnt the only reason you might use braces. alot of builders use different bracing patterns to “tune” the way the guitar sounds.
so as you probably know by your experience, youll need to brace your soundboard. the most common bracing material is balsa wood because it is light. but since your making a carbon fiber guitar, id say go the whole way and make the braces out of carbon fiber!
heres a good site about bracing a wooden soundboard with carbon fiber. ive also read that carbon fiber and epoxy is common for bracing, as well as carbon fiber and balsa wood.
check out these sites for more info and to help decide on your pattern. i ope i could help a little bit!
alex welsh (im assuming hes your classmate?) asked me the same question, as well as this:
“im just wondering what your most hated task is.. ‘cause im sure it ain’t ALL smiles and sunshine”
good question haha… to be honest, this really is quite my dream job, tho its not for everybody. my worst task is prob comparable to the best part of some of my other jobs. i guess my least favorite thing to do, as pussy as it makes me sound, is wrap cables that have five bands worth of spit and sweat on them, and cleaning nasty sweaty guitars every night. this was a problem for me at first because i was a bad germaphobe, but ive gotten much better out of necessity haha.
