Ukulele building tools - fret calculator

My buddy, Daniel Hulbert over at Circuits and Strings builds some AMAZING stringed instruments (like this little pocket uke above).  Click that link and check out some of his work.  He also has some free building plans at his site!

In addition to all that awesomeness, he also put together this Fret Calculator Tutorial, complete with some guides to help people like me who aren't very good at building.

Rejoice novice uke builders!  Help is here!
