Set of steps made to scale? (6)
I believe the answer is:
ladder
This clue is a double definition.
'set of steps' is the first definition.
(I've seen this before)
'to scale?' is the second definition.
(thesaurus)
'made' acts as a link.
(Other definitions for ladder that I've seen before include "something that can send you in the opposite direction?" , "Climbing structure" , "snag in hose" , "Set of rungs" , "See 12" .)
