When creating a miniature house model, having a functional door is ideal for creating a more realistic model. A simple door latch can be created in a short amount of time that will allow you to close the door when displaying and easily open the door to view the interior. A miniature door latch is an admirable addition to any house model because it creates a more lifelike viewing of a model, which can be a great feature when marketing a model to sell a home.
Assemble the latch base. Select two of the 1/4-inch by 1/8-inch sections of balsa wood and glue them together to make an L-shaped wood structure.
Attach the latch base. Super glue the L-shaped latch base to the exterior wall immediately to the opening side of the door. This should be a standing L so that the latch can rest gently on top of the structure.
Cut the sewing needle. Take the wire cutters, and cut the sewing needle to leave a 1/2-inch section on the needle end. Discard the sharp needle section.
Attach the latch. Lay the remaining 1/2-inch by 1/8-inch section of balsa wood on a flat surface. Press the sewing needle section through the side end of the balsa wood section until the needle head is flush with the balsa wood. Gently grab the needle that protrudes from the opposite side and spin the latch in your fingers.
Attach the latch to the door. Apply a small amount of super glue to the sharp end of the needle. Line up the latch to the latch base and firmly press the needle into the door until the latch rests upon the door.
Test the latch. Allow the super glue to dry for ten seconds, then gently spin the latch around to test movement. Spin the latch to stand vertically, close the door, and slide the latch into the latch base.
You can also reverse the mount process by placing the latch base on the door and the latch directly on the wall of the building.
