Official Luthiers Forum!

I'm beginning a new project: a Martin-style 00 12-fret short-scale guitar. At the customer's request I'm trying to stick with Martin dimensions as much as possible.

I have a tracing pattern with body shape and bracing layout.

What I don't have is specs for the sound hole. (I also don't know anyone in my neck of the woods with this kind of guitar).

Can someone tell me the position of the soundhole (i.e. distance from 12th fret to center) and the diameter of the soundhole?

Any other information about these guitars would be lovely (links, etc).

Thanks!

Morgan.

Dan,

They're commonly 3 3/4" dia.

Put it just south of the end of a 20-fret fretboard and you'll be close enough.

On most guitars I saw it seems to start just a bit behind the 21th fret line.

Nice guitar and spruce Todd.

not sure whose plan that is, but I make mine 6.75 to centre from the 12th fret, with a 20 fret board (bound to about the 21st) .. X brace is 1/4 x 1/2 as well ....

Things have probably changed over time but my 1927 00-21 is 6.920" from the 12th fret to the soundhole C/L. Transverse brace is .253 x .600 ( pretty thin )and the X is .250 x .500.

If you want to follow Martin traditional the sound hole is 3 3/4 as stated . The position of the sound hole will be 1/8 below the end of the fretboard. So if you have the fretboard plot the center of the sound hole to fall there

Martin supplied 00s over the years with 18, 19 and 20 fret fingerbards at various times.
Of course the earliest 19th century 00s had 18 frets but moved to 19 and 20 in the early 20th century.
In the 1960s the 000-21NY had a 19 fret board again while the concurrently produced 00-21 had a 20 fret. Later when the NY model was dropped the regular 00-21 went back to 19. Confusing?
Anyway, I kind of like the look of these with 19 where the board is trimmed at the 20th fret position and located exactly midway of the innermost rosette ring.
These guitars almost always (the 1970's 00-45 had a long 25.4" board) used a 24.9" scale.

A classic American design and perhaps the most beautiful of all.

Wow! I really appreciate all the info.

I'm fairly new to OLF and I sure am appreciating the value in this kind of community. I was spending hours googling and trying to find random info and not coming up with much. It's so much nicer to throw a question out there and have people who are genuinely interested in the subject come to my aid. Thanks!
