Making up some custom laminated bindings out of some lovely quartersawn pau ferro and some w-b purfling, step-by-step (bottoms to top). The prefab stuff has gotten way expensive for what it is, and this way you get exactly what you want for less.

Go-bar deck built and bridge plate glued and clamped. (Did a little more work on the sound hole reinforcement, too.)

It’s actually old school technology, quite common in the luthiery world. Although the kids today tend to use fiberglass rods. But, I got wood scraps galore, so I went with walnut.

I was confused on Don's first build, when he kept saying "Go-bars" and I said, "But they're really stay bars, they don't go." He just looked at me weird..... :LOL::ROFLMAO::p

Making purfling? My word, how thin do you have to cut the strips? Do they have a tendency to break? What do you use to adhere the strips to each other?

Sorry for the questions, but this is fascinating and I am in awe of your abilities!

To clarify, the purfling (the very thin white/black strip) is not homemade. I just laminated it to some pau ferro to make the binding. After glueing with Titebond (original), I used my drum sander to bring it down to 1.8mm.

How do you know which fan brace pattern to select out of the list of many?
Usually you start with the bracing pattern of a builder you admire whose sound speaks to you. So, in the case of my classical, I started with Robert Bouchet’s pattern (or at least one of them; like most builders they will evolve over their career). Then I combined that with the ideas of Jeffrey Elliot, whose innovations made a lot of sense to me.

In the case of this flamenco, I listened to many different guitars. One of my reference tomes gives the patterns and measurements for many historic guitars, and provides a CD of them in action. The sound that i liked the best was of Marcelo Barbero and his son. So I’m combining their patterns (the son was really just a refinement of the father) with a dash of me.

Very, very cool, Chris! Keep the pix coming!!!!! Love it!

While we're discussing it, what's the knock on fan bracing for steel acoustics? Why isn't it used? Not strong enough? Bad sound? Just curious!!

Yes, not strong enough. The tension of nylon strings is far less than steel strings, and since they are play solely with fingernails, the bracing is far lighter to allow for maximal transmission of vibrations and maximal touch. A steel string exerts far more force and the driving force is much higher, allowing for a beefier bracing to counteract the tension (and delay the guitar folding in on itself) and capable of dealing with the greater driving force.
The overall tension for steel strings average at around 150 to 200 pounds whilst nylon strings are around 75 to 90.
