Wow, this was an unbelievable post. Thanks so much for doing this as I am, today, looking to buy the exact same guitar for $200 CDN. Haven't yet seen what I'm in for but the owner seems to think there is limited bellying. We'll see.
Either way, the process and pictures was amazing. The most complicated think I've done to date is refret a 1978 Yamaha FG-375S, but I'm pretty comfortable doing most of what you did except adding the bolt on neck. That was insanely detailed.
Unless I missed it how did it come out from a sound and playability standpoint? Finally, thank-you again for all the work, pictures, technical advice, etc. It was like sitting in a master class of luthiery. Much appreciated.
