Turning Spindle Turning, or turning from two opposite centers, is a popular woodturning technique referring to a process whereby a wooden wheel is turned on its pivot axis. As the name suggests, spinning wheels turn on their spindles while the spokes of the wheel are spun around a hub by a hand or arm. Turning spindles are often used on lathes and hand turned scrollwork.
Turning spindles are used in many woodturning processes. Some of these include hand turning, jig turning and cross turning. Some of these include lathes with turning spindles that turn as well as an independent turning spindle. The spindles are either turned independently or on the centre axis of the lathe.
On hand turning, a person lifts the wheel off the lathe’s spindle and spins it on the hand crank. The wheel then moves in a clockwise direction on the pivot axis until it hits its opposing centre point.
Jig turning on the other hand is when the spindle on the spindle lathe turns while the working piece of wood is placed under it. This type of turning requires a hammer and a taper in order to hit the spindle with enough force to impart it with spin. A similar procedure also takes place at cross turning where the spindle lathe turns the wheel on its axis while the workpiece is supported in a hand crank. The crank is usually a hand drill with a spindle attached to the crank.
Cross turning is when the spindle on the spindle lathe is turned at an angle to the spindle axis and a cross is formed. This cross is then drawn across the workpiece to complete the turn. Jigs can also be turned in reverse by pulling the spindle away from the spindle lathe in an opposite direction and allowing the spindle to turn counter clockwise. This can be done by raising a pinion drive and pushing it through a hole on the spindle while the wheel is turned in the opposite direction.
Turning spindles are made of several different materials. The most common among them are brass, iron, and aluminum. Many of them also have wood finishes like oak, walnut, birch, and cherry.
Turning spindles are available in all shapes and sizes. They can either be simple or complex. A simple turning spindle is made of brass and has a small diameter and a flat cross on its shaft. A complex one is constructed out of brass and is shaped in a manner that it resembles a bowl or a globe.
Turning spindles are usually made in pairs. There are spindles that are powered separately, and others that are operated by the same lathe as in a multi-speed machine. Many spinning lathes have the spindle on its own spindle and they are powered by a separate motor.
Most spinning lathes come with a manual, which is used to start the spindle when turning. Another manual is used to stop the spindle from turning and a stop mechanism to protect the spindle when it stops.
