Wizard person at the wheel (6)
I believe the answer is:
potter
I believe this clue is a double definition.
'wizard' is the first definition.
(Harry Potter)
'person at the wheel' is the second definition.
(someone doing pottery with a wheel)
(Other definitions for potter that I've seen before include "Craftsman - dawdle - Harry!" , "Dabble; dawdle" , "Maker of earthenware dishes" , "The Harry - - books" , "Person who makes ceramic objects, vases etc" .)
