I saw some Guitar stand made out of PVC here, and since I salvaged several pieces of wood from some ikea furniture that i found on the streets I made mine with them.
Step 1: Layout and Materials
The idea is pretty straight forward, as you can see in the pic. the dimensions are standard, 36' long, 16" deep and 28" high, the hight of the horizontal bar (for support of the neck) is around 26" from the top of the piece @ the bottom , and the distance between the two bottom pieces (where the body of the guitar goes) is around 12". you can try with the guitars to get a better configuration.
I use 3 pieces of 1 1/2" x 1 1/2" by 36" for the bottom pieces and the horizontal top.
2 pieces 1/2" x 1 1/2" by 28" for the Vertical sides and some 2 planks of 1/4" x 2 1/2" x 16". All salvaged from some ikea bed that i found in the street.
The screws (8) are Allen Screws for wood ( the ones that came with bed, the Ikea ones), but some drywalls can do it too.
For the pieces that hold the guitars in place (or separators) I use wine corks and some drywall screws.
