  • Patent number: 5645117
    Abstract: A turner holds a wood blank while positioning it adjacent a cutting bit of a router to cut the blank into a shaped cylindrical object. The turner includes a mandrel and two mandrel wheels attachable to ends of the mandrel, which each have finger gripping portions. A wood block is disposed on the mandrel and the wheels are attached to the mandrel. Spacers may be used to position the wood block. The mandrel/wood block assembly is then moved adjacent a cutting bit, such as a router bit, to remove wood from the wood block. This enables generally cylindrically shaped objects to be formed which may then be polished and finished and used in pens, mechanical pencils, handles and like holders.
