What Is Swing on a Wood Lathe?
The lathe is a vital tool for the woodworker who wishes to turn wood to make rounded or decorative pieces. Two terms often used in describing lathes are the length of the bed and swing.
-
Swing Defined
-
Swing is the largest diameter of wood that can be turned on the lathe. It is determined by the lathe bed and the tool rest.
Swing Over Bed
-
The bed of the lathe is the flat mounting surface where the headstock and tailstock (which hold the wood in place) and the tool rest are mounted. As the wood rotates, it must clear the bed, or swing around it.
-
Swing Over Slide (or Rest)
-
The tool rest is sometimes called a slide and its location could also restrict the diameter of wood that can be turned. The tool rest is adjustable and may or may not be the same distance from the center line of the wood as the bed.
Headstock
-
Some lathes are equipped with a headstock that can be rotated out away from the bed for the purpose of turning bowls and other pieces that do not need to be supported on both ends. This feature can increase swing.
Considerations
-
Choose a lathe based on what will be turned on it. For example, swing over the bed does not need to be nearly as large for someone who turns stock for writing instruments as it does for individuals who turn posts.
