Guitar-Navigator

It happens to me again and again that I compare and can not say just exactly different guitar forms, in what the greatest difference lies. For example:

- I would like to know exactly whether the Pickups are attached in the same position to the scale length,

- or by how much millimetre are the pot knobs moved approximately?

- or exactly where, for example, the bridge should be placed ... etc.

 
Currently, when every square yard of the earth by two coordinate numbers can be accurately tracked, why should not something similar for the guitar landscape be good?

For the vintage analyst might have a precise navigation system with coordinates to compare all the important positions helpful

A hobbyists could have a collection of data from self-measured proportions to develop and share with others. This has not always safe without any misunderstandings.

And when designing the guitar with a CAD software these coordinate values could make the work easier very much.

This cross the midline and the scale line could indeed trigger religious thoughts, but we are talking only about pure geometry.

Where does the zero point lie?

The upper display is suitable mainly for the body shape and overall proportions. At the peghead as a detail, it is preferable to zero exception centered positioning of the nut front edge.

 

The neck and the fret distances, although one could measure distances starting from the bridge, but it is customary and almost better to zero from the nut to the left, toward the body (+ X, exceptionally) to go out.

And one needs the spatial coordinate for the neck in addition to describe the neck profile. To this the zero should respectively lie on the centre line and on the fingerboard surface (flatly, without radius without frets).

With the same zero position, the profile representation gets more open however into polar coordinates. To include the profile contour sufficiently exactly suffice 12 steps in 15° distance completely. Who thus fairly often deals, an scan device can make itself to transfer the profile courses of a popular guitar neck to the drawing paper.

And, if somebody would ask me where the volume knob of my Strato exactly lies, I answer (after a brief glance at my still modest, database):

29.4 / -54.5 or more precisely:

X = plus 29.4 mm and Y = minus 54.5 mm wide (from zero point).

Body-Polarography

In a spider's web can be measured various body contours much easier to compare or. It takes as really only one coordinate value. The other value for the angle you can specify as star-shaped grid. That would be in the Cartesian grid also possible, but it would be much less clear. If necessary, can be converted to this formula:

X = Distance .  cos (angle degree);

Y  = Distance .  sin (angle degree)

Who thinks that polarography is something completely different, right, of course. Yes, it is the electrochemical method of analysis with the Mercury-taste electrode. But even Professor Heyrovsky was awarded the Nobel Prize. For that I would have to exert myself more.
