Who’ll do fixing of hair netting for queen (9)

Ross

I think it could be either:

performer

downcomer

I'm a little stuck... Click here to teach me more about this clue!

'who'll do fixing' is the definition.
I can't tell whether this definition defines the answer.

'hair netting for queen' is the wordplay.
'hair' becomes 'down' (I've seen this before).
'netting for' becomes 'com' (I can't explain this - if you can you should believe this answer much more).
'queen' becomes 'ER' (Queen Elizabeth).
'down'+'com'+'er'='DOWNCOMER'

'of' is the link.

Can you help me to learn more?

(Another definition for downcomer that I've seen is " Pipe".)

I've seen this clue in The Times.
