Make law better than revolutionary lashings (7)

Ross

I believe the answer is:

redraft

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

'make law better' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.

'revolutionary lashings' is the wordplay.
'revolutionary' becomes 'red' (red can informally mean a communist).
'lashings' becomes 'raft' (I can't justify this - if you can you should give a lot more credence to this answer).
'red'+'raft'='REDRAFT'

'than' is the link.

Can you help me to learn more?

(Other definitions for redraft that I've seen before include "second edition" , "Altered document" , "Corrected version" , "Change outline" , "Make a copy" .)

I've seen this clue in the Sydney Morning Herald.
