Turner catnaps when sozzled (7)
I believe the answer is:
capstan
'turner' is the definition.
(turning or revolving machine part)
'catnaps when sozzled' is the wordplay.
'when sozzled' indicates anagramming the letters (sozzled can mean drunk).
'catnaps' is an anagram of 'CAPSTAN'.
(Other definitions for capstan that I've seen before include "Rope-winding cylinder" , "Apparatus to wind cable" , "item of winding gear" , "One used to wind" , "revolver" .)
