Spindle turning, or turning between centers, is a woodturning method referring to a piece of wood on a wood lathe that is being turned on its center axis.
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 
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.
Spindle turning is the method used for items such as chair and table legs, lamps, cues, bats, pens, candlesticks etc. i.e. long and thin objects.
