In order for a straight pin hinge system to work, the door edge against the side of the cabinet must be gently rounded on the side where the hinge will be placed. Lay your doors out side by side so you can tell where the center of the double doors will be. Round the edge of the cabinet door on the side you want the hinge to be, rounding it evenly on the front and back of the door as shown. Repeat for the other door.
