Abstract
A manual glass lathe used for shaping and coloring clear glass tubes. The manual glass lathe, in the preferred embodiment, comprises a tubular handle, designed to be held in one hand, and a thumbwheel located towards the working end of the handle, and is used by a glass-blower to precisely control the spin of a glass workpiece and the proximity of the workpiece to a flame and to various shaping tools and/or fuming rods. The handle makes use of an interior arrangement of bearings and o-rings to center and hold the mandrel, and also comprises an inner sleeve used as an inertial weight to enhance spinning momentum. Also a method for using such a manual glass lathe to shape and fume glass workpieces.
