Poorly made glove has split down the middle (2,6)
I believe the answer is:
go halves
'split down the middle' is the definition.
'poorly made glove has' is the wordplay.
'poorly made' indicates anagramming the letters.
'glove'+'has'='glovehas'
'glovehas' is an anagram of 'GO HALVES'.
(Other definitions for go halves that I've seen before include "To follow the Dutch method" , "share all costs" , "Share equally" .)
