Non-printed Parts

  • Suggested Spring 1 (x21) — aka “Weak Spring” — Century Spring Corp. Stock #: U-4 — this spring is not as strong as spring 2. We use it to mount the electrodes. The low “Rate” (1.3 lbs/in) makes it more forgiving and comfortable when holding the spikey electrode against your head. This process is described in more detail below (in the “Assembly Instructions” section).

  • Suggested Spring 2 (x5) — aka “Strong Spring” — Century Spring Corp. Stock #: S-71315S— this spring has a much stronger “Rate” (14 lb/in). This makes is ideal to act as a standoff at locations where you do not have a spiky electrode.
