Check out woodcutter and go from one extreme to another (6)
I believe the answer is:
seesaw
'go from one extreme to another' is the definition.
I can't tell whether this definition defines the answer.
'check out woodcutter' is the wordplay.
'check out' becomes 'see' (I've seen this in another clue).
'woodcutter' becomes 'saw' (I've seen this in another clue).
'see'+'saw'='SEESAW'
'and' is the link.
Can you help me to learn more?
(Other definitions for seesaw that I've seen before include "Fluctuate" , "Plaything that's ridden up and down" , "Playground device" , "Go one way and then the other" , "Recreation ground item" .)
