How can I get my cupboard doors to close after installing new hinges?
Plain hinges with no springs cannot keep doors snug up against the cabinet even under the best conditions. At best the doors sort of "float" near the fully closed position. More often than not the doors drift open slightly. You need some sort of catch to use with plain hinges. There many sorts, usually relying on some sort of spring or magnetic device to hold the door closed but release easily when pulled upon.
