Endpin modification test launch

  • Launched from ground level
  • Projectiles: Water balloon, tennis ball
  • This was just a test to visually see if the modification made any difference. The balloon distance was approximated. The tennis ball's distance was not measured.
Test 1
  • Balloon Weight: Not Measured
  • Balloon Launcher: Rosa
  • CW Prop Angle: 180
  • Total Distance: Appx. 90 ft.

Test 2
  • Tennis Ball Weight: 56 g
  • Launcher: Adam
  • CW Prop Angle: 180
  • Total Distance: Not measured
Test 3
  • Tennis Ball Weight: 56 g
  • Launcher: Rosa
  • CW Prop Angle: 180
  • Total Distance: Not measured
Conclusion:
  • The modification did not improve the trebuchet. It's performance was about the same if not slightly worse.
Next Time:
  • Create new, longer endpin.

Endpin Modification

Took endpin piece to Bob to be modified.  Pin was removed successfully from the endcap, and bent a few more degrees.  Endcap broke while trying to replace the pin.  Glued together.  Will wait a few days before launching.
