Thanks Marshall, I haven't done any of those yet, just glued my plates up, didn't put a 'back stripe in, darn it. I'ved planed & sanded them down to .100 and that's all, I'm ready for the next step?
Think of the guitar as 4 separate parts. Neck, top, sides and back. Complete each part as much as possible before joining to another.
Before the neck is joined to the top:
The neck blank should assembled and trued, shaped at the heel and the slots cut to receive the sides, and the ramp where the top sits cut to the exact depth of the top. Cumpiano and Natelson to a good job of describing this.
The top should have the rosette in, soundhole cut and braces on.
The rosette channel will be a little dicey to cut on such a thin plate without going through the wood, but it's do-able. It will be proud of the surface and need leveling without taking anything off the top surface. Glue on the braces and the soundhole reinforcement, which all may require two or three steps depending on how it's done.
I don't add a back strip if the 2 pieces come together and I have a hard time seeing the joint. Why tempt fate for a purely decorative element? But if you want to insert a back strip, cut a dado and put it in. Or cut in half and re-join it.
All of this is easier said than done and mistakes will happen. They just need to be corrected and usually can be, without any bad effect, especially early on in the process. When the guitar goes flying out of your hands in the final step on the buffing wheel... well, it's crying time again, as the song goes.
I used Cumpiano and Natelson as one reference for my first build and I think they do a good job with the sequence of steps. I needed a benchtop guide for constant reference and as I mentioned, the mingling of the steel and nylon measurements, etc made the info hard to find in the middle of a procedure.
Basically get the neck, top and back all ready to go. Then glue neck to the top. Then the sides onto the neck/top assembly, and then put the back on.
