Turner does better with brown (7)
I believe the answer is:
capstan
'turner' is the definition.
(turning or revolving machine part)
'better with brown' is the wordplay.
'better with' becomes 'caps' (I can't justify this - if you can you should give a lot more credence to this answer).
'brown' becomes 'tan' (tan is a kind of brown).
'caps'+'tan'='CAPSTAN'
'does' is the link.
Can you help me to learn more?
(Other definitions for capstan that I've seen before include "Rope-winding cylinder" , "One winds up" , "boat's winding gear" , "Tape-, cable-driving spindle" , "revolver" .)
