Chopped hinges in at an angle?
I am replacing a door which the previous carpenter has chopped hinges at an angle for. Although flush to start they go deeper into the door the further away from the edge of the door they are. The idea seems to be to have the hinges slightly ajar when the door is closed. I can’t think of a reason for this. Both rebates are identical, so it’s by design. Can you think of a reason why this has been done?
