Gang spotted wood cutter (7)
I believe the answer is:
bandsaw
'wood cutter' is the definition.
'bandsaw' can be an answer for 'cutter' (I've seen this before). I'm not certain of the 'wood' bit.
'gang spotted' is the wordplay.
'gang' becomes 'band' (both can mean a group of people).
'spotted' becomes 'saw' (spot can mean to see).
'band'+'saw'='BANDSAW'
Can you help me to learn more?
(Other definitions for bandsaw that I've seen before include "Tool used by a carpenter or joiner" , "cutter" , "Powerful tool" , "one might cut deal" .)
