I'm going to do what I should have done long ago, that is, offer the plans for free
The zip file includes three versions of the plans, from 2002, 2005, and 2010.
The 2010 version includes a 3D Blender model of the guitar, the same model used to create the renders here.
There is a difference between designers and builders. I thought one would naturally include the other, but it's not always so. People tend to do what they do best, and continue to focus on it, improving their efficiency and quality as they progress in their chosen field. Others take a wider focus, taking in the view of larger systems, possibly at the expense of directed improvement in one specialty or another.
I approached guitar design and construction as an integrated system. A design must be functional, prototypes must be built so as to know the design is buildable. I started out designing my first guitar by sketching in notebooks, then sketching on a piece of wood, then cutting it out and shaping it with tools until the hardware could be installed. Once the hardware was on, the final adjustments could be done so the instrument could be played. It is difficult for me to build prototypes now. I'm trying to get by with making 3D models. That's why I don't charge for the plans anymore, because I haven't actually built any prototypes in quite a while.
I took a half-finished guitar to a guitar factory in Costa Rica and paid them to finish it, thinking they might be interested in learning something about a new design, possibly with a view towards producing it in wholesale quantities. I neglected to take into account that their primary business is guitar fabrication, and the goal is to sell guitars to people who are looking for a conventional instrument. Naturally they can't afford to invest time on an untested new idea.
They did finish the guitar, but they didn't make sure it could be played in the end, and it turned out not to be the case. When I went to get it from them, it looked very nice and shiny, very similar to a guitar. On closer inspection it became apparent that a lot more adjustment / construction would be needed to get it to the point where strings could be installed.
I realize now I will have to provide much better instructions to commercial builders in the future. I don't know why I keep being surprised when others don't understand my complete vision after a brief explanation. The wide focus can leave a large blind spot at the point of origin. Gotta work on that....
A year or so ago I got email from someone at a guitar factory in China asking if I was interested in having my design mass-produced. Of course I said yes, and we exchanged information about the design and prices etc. Now I have to create a set of blueprints in a CAD program and send it over and they will build a prototype for my approval, then we can start production.
