Just thinking, for future developments, a stronger back may be needed. Perhaps achieved by a thicker ply back, domed and braced as in "normal" acoustic guitar backs. Or perhaps a single, strong, longitudinal brace from the neck block to the tail block may achieve the same thing. If you are concerned about weight, perhaps make it out of spruce, but shape it like an I- beam, with carbon fibre reinforcing on the top and bottom of the "I"??
Great video - thanks! How did you determine where the problem? How would you have braced the back if you knew this ahead of time? Was this also a problem with the previous guitar?
Hi Ben, the back was too thin (2 mm Aircraft Plywood) and the bracing of the back wasn't robust enough. Now I would recommend 5mm thickness for the back without any bracing. My previous guitar had no such problems. The body was routed out of a massive blank of mahogany. Best regards Thorsten
Good question! I wasn't sure whether the aircraft plywood top was stable and stiff enough. But as it turned out, I could probably have done it without the bracing.
The design is beautfull with wrong material. You shouldn't use anything weaker structurally (less dense) than what is usually used for manufacturing instruments. Why not carbon fiber?
Mannn I would love to have one of your guitars its unique and sounds so beautiful.
Maravilloso!!! Gracias por compartir voy construir una yo también.
Like the spanish foot. Also the guitar sounds fine

"a stronger back may be needed" - You're so damn right ;-) That's what I thought after finishing the project.
I love this so much

What kept you from doing the bracing on this build that you did on your acoustasonic style?

@thorstenfaust153 good to know! Much appreciated
is this modification in your drawings?
👏
