Luthier Fret Ruler - README

An Inkscape extension that draws full sized Fretboards for stringed instruments. Guitar, Ukulele, Banjo, Dulcimer, etc

Appears in Extensions menu under Music.

Will draw a fret ruler in three useful ways:
1. Ruler - ideal as a Lasercut metal rule or paper printout,
2. Template - to be used as a guide in a router or table saw,
- e.g. https://youtu.be/0niBEfb5csk?t=95
3. Full neck to be printed and glued onto the neckstock for accurate sawing and marking. Includes fret marker placement and tapered necks.

Scales:
The fretboard can be drawn with a single scale or in a fanned format with two scales, on the bass and treble sides of the fretboard.

The methods for constructing scales are:
- 12th root of 2
- ratios of 17.817, 17.835, or 18
- scala files.

Also draws a curved arc template for curved fretboards. This is in two styles:
1. Block - to be extruded into a sanding block or neck support. Possibly using the Inkscape to openscad extension to export to an STL for 3D printing.
or:
2. Thin finger-like tabs to set the correct heights of strings at the saddle.

Be sure to unzip the scales zip enclosed into the same directory. It will create a scales folder with 4580 interesting .scl (scala) files to choose from. 
There is a special tab in the extension for finding useful scales in this enormous resource.

Works in Inkscape 1.0 - 1.3
