Pendulum Bob Attachment?
  • Hello Dave -

    Is the pendulum bob supposed to be attached to the threaded rod in any way?

    I have the two nuts to adjust the height on the threaded rod, but the brass weight (tube) just lifts off. I don't see anything in the plans about securing it and I'm out of brass nuts and stops. Is it supposed to be this way, or have I lost another part?

    I'm afraid that, if left loose, curious fingers may lift it off by accident.

  • The bob just slips over the threaded rod, and is held by our good friend gravity.

    As to curious fingers, they would also have to be quick fingers to pluck off the bob from a swinging pendulum :-)
  • Put one nut under the brass weight and one nut on top of brass weight
