Back radius. Martin 000-28 EC

[ClaptonWannabe2]

Getting nitty gritty time now. What is Martins back radius for this guitar? I’d like to make it as close to a clone as possible. Bought LMI plans but the back radius is not shown.

I am armed with the Cumpiano Book, LMI plans, and this website moving forward.

Sounds like those plans are missing info.

The StewMac plans have full size brace profiles. I copy, cut out, and glue to brace stock to cut out. Use same profile to make a radiused gluing caul. But then I'm always looking to simplify building. (I often buy shaped bracing from Martin to maximize laziness if available for the guitar shape I want.)

Others on this list can tell you the back and top radii but I build Martin clones without needing to know them.

Seeing as LMI sells a brace-shaping tool with 25' and 15' radii, I'm guessing that the guitars built off their plans might correspond. Could always ask, an answer might be offered.

I use 15 foot.
