Here is a folding guitar stand that I made out of copper tube. It was ten times the trouble of simply buying a factory made stand, but if you are a musical plumber, you might enjoy having one!
You can download a technical drawing with cutting list here.
Here is the stand holding a Yamaha JR-1. I really like this guitar: easy action and great value!
