Tailstock

the tailstock (see figure below) is typically used to support long workpieces by means of a live or dead center (refer to Centers in the following sec- tion). it can also be used to hold a drill or chuck to bore holes in the center of a part. Custom arbors and tapers can also be cut on your lathe by using the offset tailstock adjustment.
