The into-window screws with screwdriver/spanner wouldn't budget.

o Heated them, then soaked them with flick easing oil.
o Left to cool for 1hr
o Came out as if they'd been screwed into cheese - no effort

Going with the 3" stainless hinge after all, since the original 2.5" had
the holes in different places on the two halves, so can't just replace.
Painter's going to love the state I made of his paint tho tomorrow!
