Self Centering Pen Blank Vise

This self-centering drill press vise design is inspired by the components of traditional woodworking hand screw clamps. The entire vise will “float” to clamp onto a drill rod clamped in the drill press chuck. Once the jaws are centered, the base will be clamped to the drill press table. Subsequent pen blanks or other stock clamped in the vertical V-groove in the jaws should be centered on the drill press chuck.
