Make use of frame one trimmed (4,4)

Ross

I believe the answer is:

draw upon

'make use of' is the definition.
(eg to draw upon experience is to use it)

'frame one trimmed' is the wordplay.
'frame' becomes 'drawup' (synonyms).
'trimmed' means to remove the last letter (the final letter is trimmed off).
'one' with its final letter removed is 'on'.
'drawup'+'on'='DRAW UPON'
