Abstract: A system of hand-held lathe tool assemblies especially for executing large scale deep and/or hollow work efficiently and rapidly while minimizing operator fatigue. Tool working portions may be integral with their carriers or holders or may be selectively connected to them by means of a conventional chuck or collet. The butt portions of very long lathe tool assemblies permit the turner to apply forewarm and/or upper body to the tool and gain sufficient leverage to work comfortably and hence with enhanced control while performing large scale work with tool reaches from rest to tool cutting point as high as 36 inches in length. A "slicer" tool facilitates separation (and conservation) of large volumes of material without comminution in the rough shaping stages of work. Other tool forms are disclosed.
