Golden Section Gauge...


Recommended Posts

The device will describe a rectangle whose measured sides conform to to the Fibonacci sequence or ratio. LINK This Golden Section or Golden Mean, when incorporated in a piece of work, is thought to be the most pleasing to the eye.

An example would be a box 3 by 5 by 8.

All of Michelangelo's sculptures conform to the Golden section.

The Fibonacci ratio, or the golden rule, is the size ratio of one side of an object to the other. As Gene pointed out, Michelangelo use it as well as many other artisans over the eons. The ratio is approximately 1.6:1.

 

When constructed to the listed dimensions and assembled the gauge that Stick published is a simple tool that can be used to design, or check to see that the object meets that ratio. This gauge is self adjusting, so that, the ratio is constant no matter what the size.

 

Measure one face (F to H) and the other face should be the distance between G  and H. Constantly 1.6:1

 

You can construct the basic gauge smaller or larger to meet your needs; small boxes (smaller gauge), furniture (bigger gauge). When designing you can use the gauge to ensure that the final result will be pleasing to the eye. You can even use it on a sketch or drawing to ensure your dimensions are correct, even before you build something.

 

Hope this helped

Stick, how about a little explanation on what we are seeing here? Thanks!

ooooops...

sorry about that...

here ya go.... http://goldennumber.net/goldgrid.htm ....

When the gauge is adjusted the middle arm will always show the golden section or phi point between the two outer arms.

Note:  The dimensions listed actually represent the distances between the rivet centers and the tips, not the lengths of the pieces.  It's best to think of the gauge conceptually as being made of very fine line segments connecting at golden section points. The actual length of piece AF is thus a little longer than the distance from the rivet at A to the tip at F in order to give the rivet some room to hold.  The tips of the gauge should all come together when it's closed...

 

Here's a link to a free video that shows how to use a Fibonacci gauge to create and scale drawings using the Golden ratio.

 

 And how do you use this in Sketchup?

I have read a bunch of George Walker's work and he much prefers integral ratios.  He's a really tough read, though.  https://georgewalkerdesign.wordpress.com/

 

I'm not a slave to golden ratio like some friends that I have.
