Step 4Make the socket of the ball joint
I used two lego pieces with holes in them as the sockets. I just put a screw with a butterfly nut on the other end through the center hole, and put a ball (screw with ZapGel/ShapeLock head) in between each end. See the final picture to see what I'm getting at (it's really simple).
If you don't have a screw with a flat top (makes it easy to turn by hand) for the center hole, make one:
get a screw, cut off two sides of the head (I used a dremel). This makes a head that's easier to turn by hand.
