I learned about the Robert Larson 800-2875 Plastic Center Finder (Amazon link) from maker Ben Light, who uses it to drill out the center in the tin can robots he builds. Online, I see a lot of videos of jewelry designers using these. Woodworkers use them on finding centers on dowels or centering up work to chuck into a lathe.
