Abstract
A plumb bob assembly including a bob, a collet for suspending the bob from a drill press chuck, and a housing within which the collet and bob may be stored and around which a plumb bob cord may be wrapped when the bob is not in use. The housing protects the tip of the bob from damage and diminishes the likelihood that the cord will become entangled during storage.
