Rough turning is an inexact science: turning wood too thick will lead to splits, and turning wood too thin will lead to distortion that cannot be removed because not enough thickness is left. Once dry, it is mounted on the lathe a second time and turned to its final form. Rough turning is typically used on most functional work and some art pieces.
"An indescribable surface that begs for a caress of the hand--that's what I think wood should provide." [ 3 ] Raffan is known for using native Australian woods, for the architectural influences in his turned objects, and for his groupings of related objects into sets (e.g. his "Citadel" and "Tower" series of boxes, etc.)
For spindle turning, the wood is held on the lathe either by both ends (between the headstock and tailstock) or by one end only using a lathe chuck [2]. Wood is generally removed by running a turning tool down the slope of the wood from a larger diameter in the wood to a smaller diameter.
Many chucks have removable jaws (often the top part is removable leaving the base or 'master jaw' assembled with the scroll), which allows the user to replace them with new jaws, specialised jaws, or soft jaws. Soft jaws are made of soft materials such as soft (unhardened) metal, plastic, or wood. They can be machined as needed for particular ...
Segmented turning, also known as polychromatic turning, is a form of woodturning on a lathe where the initial workpiece is composed of multiple parts glued together. The process involves gluing several pieces of wood to create patterns and visual effects in turned projects.
Hard turning is a type of turning done on materials with a Rockwell C hardness greater than 45. It is typically performed after the workpiece is heat treated. [3] The process is intended to replace or limit traditional grinding operations. Hard turning, when applied for purely stock removal purposes, competes favorably with rough grinding.

Its jaws are made of wood or metal, the latter usually faced with wood, called cheeks, to avoid marring the work. [4] The movable jaw may include a retractable dog to hold work against a bench dog. A "quick-release" woodworker's vise employs a split nut that allows the screw to engage or disengage with a half-turn of the handle. When disengaged ...
