Hi All:

I am wondering if anyone has built from this 1918 Martin 1-18 plan. The notes on the plan by Ted Davis describe it as lightly built for gut strings. LMI lists it with their steel string plans. As near as I can tell the plan has elements of both. I have looked inside two Martins (1895, and 1925) apparently built for gut strings. They both were X braced and had pin bridges but if I recall correctly, the braces were lighter than the braces on the Davis plan (1/4x 1/2 before scalloping). Top and back thicknesses seem a little thicker than one might use for gut or nylon. The top in the guitar copied for this plan was Adi.
Any suggestions? Thanks.

Hi George.
With considerations to the thickness of the top, it's stiffness, and the stiffness of the bracing, 1/4" x 1/2" would be fine for a steel string guitar.

I've built two with that plan, and loved them both. The first was sitka/mahogany, and had slight issues of some notes playing louder than the others up and down the neck. The customer has restrung it with silk&steels, and she very much loves it. The second, adi/blackwood is one of the best, if not the best guitar I've made. I left the bracing dimensions exactly as on the prints, and only varied the plate thicknesses to suit the actual pieces. Also, I would personally recommend making the fingerboard just a bit thicker. I put purfling on the bottom edge of the FB binding, and when I radiused the FB it was pretty dicey, I would definitely have liked some more wiggle room, but it worked out all right in the end. Anyway, I think it's a great design, certainly a great place to start from and adjust to taste. I can't hardly wait to make another!
Cheers

This was interesting. 200 views and 2 responses. I guess the Martin 1 plan is not all that popular. But then Martin no longer makes the 1 because no one was buying.

Fortunately the 2 responses were quite helpful so I got the help I needed. Thanks very much.

George.
It's pretty goofy. Players usually want big guitars. Builders love little guitars. So... you end up building little guitars and have to almost give them away. I can't stay away from them, I want to make a 2 size guitar that's good for bluegrass!

David:

I would love to hear the 2 when you finish it.

Here is a pic with my small body hybrid or crossover in comparison to my standard classical and a Taylor GA4.

I built my first 1-18 in 1997 from Ted's plans and from spruce I got from him... adirondack/mahogany.. it was also my first small guitar build. I overbuilt the top somewhat and as a consequence it is not as loud as I would have hoped for;
I have built three or four others of the same size and with lighter bracing and thinner top and have been very pleased with them. I love small bodied 12 fret slot head guitars!

Someone posted the same question over on the MIMF a while back, so you will find a bit more information in that thread. I've made two guitars based on the Martin 1-18 1918 plans. I didn't try to copy it exactly--basically used the body shape and general bracing pattern but making the string scale longer (I believe the plan is a short scale). I love the resulting sound. I find it full, balanced, great resonance, really responds well to finger style playing (especially blues/jazz), and also light folky kind of flat picking. I think the size 1 is a really successful instrument. People just seem to think that bigger is better. Their loss.

Thanks for the responses. Now I am excited about getting this guitar done. I play fingerstyle so a little light on the bracing seems to be the way to go.
