We had a couple of tilt and turn windows which have never been

I haven't got any tilt-n-turn, but the grub screws on some uPVC door
hinges are rather clever (i.e tricky until you realise how they work) a
few turns in one direction act as left/right, then continuing to turn in
the same direction they act as in/out ... maybe look what manufacturer's
system the frames use?
