This project was inspired by a video by Steve Ramsey from Woodworking for Mere Mortals (incidentally, you should definitely take a look at his website if you haven’t). Anyway, it’s a gauge to determine the Golden Ratio of an object. The ratio (1:1.618) is considered to be perfect natural beauty, and this gauge helps you determine that ratio for your smaller projects.
I enjoyed making it a lot, and my wife (a physicist) also appreciated the math and engineering behind this project. I have a blog post about it as well if you’d like to learn about my method a little bit more in depth, and a little bit behind the math of the Golden Ratio.
Edit: http://lumberjocks.com/jcboysha/blog/32753 there is the blog post link for my post about this project.
also, picture 3 is of one of the failed Phi gauges I made.

Great build – it’s also known as a Fibonacci Gauge and if you build furniture and you don’t use one of these you are making a mistake!
That ratio can be found all over nature and, as you state, is very pleasing to the human eye.
Great job and a great explanation!
Keep up the good work – and make sure you post the pieces you make using this thing!

Where do you measure from?

The left hand two pieces in the picture form the 1 in the ratio. So the left hand long arm and the short middle arm. The two outside arms form the 1.618 of the ratio.

I just bought a set of Fibonacci guages from Woodpecker, they are well made and work very well!
Nice to see you can make your own, I wasn’t ambitious enough for that.

Being a physicist as well, I approve! I am totally into nerdy stuff like that, so put it to good use!

Ripthorn,
My wife informed me to inform you that your signature has made her day.
