A piece of flat brass stock was cut and bent around the flanged nylon spacer. This time the brass was tight enough that a rubber band was not necessary to hold it in place. Another spring was made with the narrow brass bar stock but a larger diameter was chosen to increase the flexibility. Instead of wrapping it around a toothpick the bar stock was wrapped around a pen shaft. The pen shaft was roughly 9.5mm in diameter. The flexibility was still insufficient.
A small brass rod 0.016" (0.406mm) in diameter was purchased in order wind a new spring. A toothpick was used as the core for winding the spring. The spring was cut away from the rest of the stock. A z-bend was added to one of the torsion spring arms in order to reach into the flanged spacer. Solder was applied to the straight spring arm and the flat bar stock used to hold the nylon spacer. The two were joined so the tip of the bent spring arm rests just above the reduced bolt on the compass spinner. A #4-40 brass nut was soldered to the bent spring arm to add inertia.
