Rivets

Hockey Off-Ice Pucks

Patent: https://patents.google.com/patent/US5792012A/en

  • three inches in diameter by one inch high (same as ice puck)
  • Improved performance by slightly increasing the diameter to 3.2 inches
    • and slightly reducing the height to 0.9 inches
  • tubular rivets require roughly ΒΌ the force of solid rivets.
  • Semi-tubular rivets are often the preferred rivet style for joints where movement is required (pivot points)
    • because the rivet material only swells at the tail.

Thoughts

  • Can I just use rivets with threads and put a bolt through?

  • So then we can re-use half when half breaks
