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.
