Steampunk Floating Arm Desk Lamp

Step 3: The "Skeleton" of the Arm

Modeled to some extent on the human arm, the skeleton of the arm required an upper arm, a forearm, connected through an elbow joint, and a hand, the actual lamp itself, connected through a wrist joint. Springs, the rigging discussed in the next section, then provided the muscles, which would move these joints.
The skeleton was put together using components found in my boxes of scrapyard finds.
