Method of outboard turning of an article (4) on a lathe (1), a cantilever toolrest support (10), and a toolrest (13). The toolrest support (13) is preferably planar and is positioned under the bed (6) of the lathe (1) below the headstock (2). A levelling plate (6) is positioned under the tailstock end (3) of the bed (8). Alternatively, the support (13) can extend along the length of the bed (8). The toolrest (13) has a tool supporting bevel (24) extending along an upper edge of the toolrest (13) and an article clearing bevel (24) extending along the opposite lower edge of the toolrest (13). Using the above and an adjustable toolrest holder (10) mounted on the cantilever toolrest support (13), an article (4) such as a bowl (4) can be outboard turned with the angle (14) between the tool and the vertical maintained approximately equal to the usual tool sharpening angle. Also the horizontal distance between the article (4) and the region at which the tool (14) is supported is maintained at a minimum. |
