Turning spindle turning, or spinning between centres, is an ancient woodturning technique, referred to as a “piece on a rotating timber” method. It involves the cutting of one side of a wooden shaft with a reciprocating saw that cuts the opposite side. The result is a wooden tool which are rotated on one axis, usually counter clockwise, and whose other sides are cut in a different pattern. The term “turning spindle” is generally used to describe the process, and it is generally assumed that the turning of a piece on the spindle is achieved by means of a wheel of some kind. The terminology is used because the tools that have been described as turning spindles, such as wheeled spindles, are actually simply turned wheels on which other materials can be mounted.
Turning spindles are commonly used for making a variety of woodworking tools. It was the art of turning a tool on a wheel that first arose during the Middle Ages, although the practice had a long history in other cultures as well. Today, however, it is mostly the spinning of a shaft by a turner who then cuts the other sides of the piece off at the other ends of their wheels. In addition to turning spindles, this style of turning a tool involves the cutting of a wide range of other materials, including copper, stainless steel, and wood. The tool is then rotated on its axis by the turner and the cut material removed. The resulting tool is then prepared for use on the lathe. The spinning is usually achieved by turning the wood onto a wooden spindle.
Turning spindles are most commonly found in woodworking shops and hobby shops where they may be used on lathes. They are not found in museums. However, some of the tools described as turning spindles, such as small hand cranks, have been found in museum collections.
Turning spindles can also be used in a variety of other applications. Some have a bearing or other bearing components attached to the sides of the tool, allowing the end surfaces of the tool to be turned over. This allows one side of the tool to be used in the same operation for making a variety of other pieces of woodwork. The other half of the tool can be turned over and used to turn another surface. In this way, one tool can turn several pieces of wood over in a very similar fashion.
Turning spindles are used in metalworking operations in which two or more tools are used on one lathe at one time. Turning the pieces of metal over in a continuous motion in a single operation helps to smooth out imperfections in the surface of the metal. It can also make the surface smooth so that it will resist bending and can be used for producing precision shapes and designs. The turning motion helps to provide strength to the metal as well, allowing it to resist impact and wear.
Turning spindles are a useful way to obtain multiple pieces of woodwork from a single tool. They have many uses and are commonly used in woodturning and metal turning. Turning spindles are sometimes called “rotary tools” and are not only used in this industry but in many other industries.
