Phi

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 at 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.
