I have wanted to make something like this but wouldn't know what to do with it once I did.

Hi Ed,
Your assumption is correct and my deflection jig does measure the amount of the top or back bending under a given weight. When I studied with Ervin, I was sent home with two tops that are my standards to what I gauge my tops to today.
The best advice i could give you is to build a jig, use the same weight and keep accurate records. You will have to build several guitars with various amounts of deflection to find what standard works best for your building style. Or you could sign up for a class to study with Ervin and shave YEARS off your learning curve. He revolutionized the way that I approach building guitars.
