Pendulum Clamp 2

Every year we have a couple Vernier DFS casualties, so I had an surplus of threaded aluminum mounting rods. I decided to re-design my Pendulum Clamp to incorporate these rods and eliminate a couple of the drawbacks of my original design. The mounting "rod" in my original design was 3D printed, so it was relatively easy to break. The new design uses the Vernier rod and a 1/4-20 nut to eliminate breaking problem. Also eliminating the 3D printed "rod" allowed me to use raised numbering on the face which meant I could easily color them with a Sharpie. Banana Plug was from a scraped piece of equipment.
