Acoustic Guitar Construction

This is one of the smartest outside the box ideas I've ever seen. So simple and minimal and cheap. You can make it any shape that is convenient - like for measuring top thickness on a closed guitar box - pre-mark the straight rod, and measure away. No it will not be as accurate as a $400 digital magnetic thingie. Heck, it's a great idea even if it doesn't work for geetars.

Well, okay, I made one of these earlier in the week. Not a difficult task BUT - It's useful in measurements no finer than about 1/16". Not useful for top gradation post box-closing.

Now IF it had a threaded rod that could fit through a threaded ferrule, it could work. Hmmm...
