Artist who uses a lathe (6)
I believe the answer is:
turner
'artist' is the definition.
(painter JMW Turner)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for turner that I've seen before include "potter" , "Lathe worker; a water-colourist" , "English artist - lathe" , "Skilled tradesman or great English painter." , "Lathe-user" .)
