Turned on a lathe

turned on a lathe
what is the meaning of this phrase? it is said in connection to a girl with nice ankles by a guy from Yorekshire
thanks

He means that she has well-turned ankles--no bumps or deformities, curved to smooth perfection as though turned on a lathe. Look in the Search Box (top of previous page) under "well turned calf" or "well turned ankle." Many generally cylindrical body parts, arms, legs, neck, have been described as well turned. Warning! Do not try this at home! (The turning of an ankle, that is.)
