Scaffolder (6)
I believe the answer is:
rigger
'scaffolder' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for rigger that I've seen before include "Oil platform worker" , "Scaffolding erector" , "Scaffolding worker" , "Sailing ship; fraud" , "'Long, pointed brush used by artists (6)'" .)
