Turning Spindle Turning, also known as turning between centers on a wood turning machine, is an antique woodturning technique in which a spindle is turned at the center point on its axis. The turning revolves around the spindle on its spindle axis, and the spindle moves the turning machine back and forth as well. This movement is usually a continuous motion of the spindle, but it can be a very fast movement, or it may be a series of smaller movements with the spindle stopped.
In traditional spinning of the turning, there is one end of the spindle which is fixed and the other end is free of any kind of support and the spindle is turned on both ends at the same time. The moving center is moved around the spindle and then moved back in order to turn the spindle again. This is what is called a “spinning spindle”, and the spindles are commonly seen made of iron or steel. A single spindle may be made of either a hollowed hollow, straight or cylindrical rod, while the two or more spindles may be made from different materials.
The turning of the spindle is a complicated process, which includes the movement of the spindle from one position to another, as well as the movement of the spindle and its supporting material. In the early days, there was no distinction between the spindles and the supporting rod, but now there are several kinds of spindles and rods used. Some rods have been made of wrought iron, and others of copper or even steel. The steel rods are heavier, because they are less hollowed, while the copper rods have the advantage of being less susceptible to corrosion.
While wooden spindles are common, they require some care and maintenance. It is possible to get wooden spindles which are perfectly suited to antique turning machines, and are quite inexpensive. In general, the wooden spindles are longer than the metal ones, but the metal ones are much heavier.
To be suitable for an antique or medieval lathe, a spinning or turning spindle has to be made of iron. Iron is heavier than steel, so the latter is not usually used in antique spinning machines. However, there are modern spinning spindles which are of a lighter material, but can still spin smoothly.
Spindles can also be made from other materials, such as plastic, but these may not be used in antique woodworking tools, because they can be damaged easily. There are also lathes made of cast iron, but they do not spin as smoothly as the spindles made of iron.
