I cut the stainless steel piano hinge to size and installed it on the door. I set it 1/8" raised from the door outside surface using 2" decking screws and a bead of caulk

I then attached the door to the teardrop door jam. I counter sunk both the hinge and the underlying trim pieces so the 2" decking screws would tighten flush to the hinge. Any raised area here will cause the door to shift and rubbing to occur on the latch side.

Be sure to flair the hinge pin after the cut.
