I use this type of hinge when I don't have a lot of space to work with. It is easy to make and functions well. All you need for this project is: a soldering iron, some solder, 1/16 inch brass rod, 3/32 inch brass tubing, and pliers.
Make sure the tubing is right on the solder. If it isn't the rod while wobble and you don't want that. Now just bend the rod into the shape seen here.
