Golden Section Gauge make your own.Posted:Jul 19th, 2017 3:29 pm
Golden Section Gauge
Make your own golden section gauge using the template below. It will work best if you construct it from heavy cardboard stock or plastic. Drill holes and place a brad at each of the indicated points. 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 rivets 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.

Note that some people call this a Fibonacci gauge, but the Fibonacci series (0, 1, 1, 2, 3, 5, 8, …) is a series whose ratios converge on the golden ratio as the series increases. I think it is more appropriately called a golden mean gauge or golden ratio gauge, as that is the precise ratio that it measures.
