Machine tool (5)
I believe the answer is:
lathe
'machine tool' is the definition.
(I know that lathe is a type of shaping machine)
This is all the clue.
(Other definitions for lathe that I've seen before include "Wood-shaping machine" , "Turning implement" , "piece of machinery" , "Machine tool for shaping metal or wood" , "craftsman's machine" .)
