I was gradually accumulating bits of woodworking gear to do just that. Then, last year I moved, and left it all behind. I'm starting again.
And the geometric calculations involved in designing the fretboard profile are fascinating.
Meanwhile I keep finding guitars that have features worth incorporating in my design.
I don't want to turn it into a career, so I want to get it right the first time. Of course the fact that I own several guitars that are different from each other probably indicates that I'll probably end up making several.
Or none. :rolleyes:
