Post subject:  Crossover guitars

I’m contemplating making a crossover instrument. Basically a nylon string guitar w specs of a steel string.
I had a Taylor crossover years ago and loved it.
Thought maybe I’d make one now:)
What’s different? How does one determine brace stiffness and such.?
Just looking for a start

Think of it as a classical guitar with a narrow neck and narrow string spacing at bridge. Brace it like a classical guitar.

That’s where I’ll need to research. I’ve never braced a classical before

I’m doing my first crossover. Box is based on Rameriz, neck is typical steel string - dovetail, 16” radius. I made the nut 1 7/8”.

Tried to post a photo with Tapatalk but it it failed twice.

Finally

Brandon, don’t you have the Gore/Gilet books? There should be all the info you need in them including a bracing layout, or at least a good start anyway…

You can search google images for classical guitar bracing. The Torres pattern is probably the simplest (Torres is to classical fan bracing what Martin is to the x-brace in steel strings). If you go the route that jfmckenna mentioned, a classical with a narrow neck, it might be worthwhile to get a plan. luth.org has a good one in the Torres SE114 plan. Bear in mind that the lower tension in nylon strings means that the strings deflect a lot more when struck, making it more of a challenge to keep the left fingers from interfering. There's also the larger diameters of the treble strings, compared to the equivalents in steel strings.

Indeed I do. Thanks for the reminder

I think there’s even a classical plan…

I did one with a L-00 body (but anything of similar size would do), falcate bracing from the G&G books, fairly light construction, bolt-on and bolt-down neck, slotted headstock. Very happy with it.

The older Taylor crossover guitars were a 5 bar fan with a slanted lower transverse brace and a spruce bridge plate.
I built one similar, 14 fret OLF Small Jumbo shape, may still have drawings/bracing template.
