You do not know this TRICK - how to find the center of small metal pipes

[JoeVanGeaux]

I've used variations of this but not using a drill. That's a cool idea and would work more quickly.

Once, I wanted to find the center of rotation of a camera mount atop a tripod for an astronomy-related project. In my case, I stuck a piece of white paper card inside the mount where the camera "shoe" would go. Then I suspended a fixed ink pen atop the card then rotated the mount on its swiveling head and frequently adjusted the position of the pen until the concentric circles got small enough to, more or less, pinpoint the precise center of rotation.

I still want to see your method for finding the center of small rods, though. Thanks for sharing!

Thank you so much my friend!
