Building a model of the Trojan Horse from balsa wood

The story of the Trojan Horse is one of the most celebrated incidents in ancient Greek legend. After years of struggle without victory, the Greek army, which had been besieging Troy, left behind a large wooden model of a horse. The Trojans accepted this as an offering, little suspecting that the wooden horse contained Greek soldiers. Building a model of the Trojan Horse from balsa wood is a fun and creative way to recreate this exciting scene.
Sketch out a rough design for your Trojan Horse. Artists' depictions of the horse vary. In some versions, it has wheels, while in others it has none. In some versions, it is a detailed sculpture of a horse, while in others it is simply a wooden model with the general shape of a horse. Use your own creativity in designing your horse.
Build a base for your model from a flat sheet of balsa wood. This will give you a stable base on which to build your legs. If your model has wheels, make them from discs of balsa wood with a dowel as an axle. Drill holes in four short pieces of balsa wood and glue them to the sides of the base, two on each side. Pass the axles through the holes before fitting the wheels to the axle.
Glue four balsa wood uprights to the base to serve as legs. You can make these from single large pieces of wood or, to create a more plank-like appearance, glue several smaller lengths together with cyanoacrylate glue or wood glue. Measure the legs carefully to make sure that they are all the same length. You may need to hold the wood in place with rubber bands or masking tape while the glue dries.
Place a flat piece of balsa wood across the tops of all four legs. Cut it to shape with a craft knife so that it is slightly wider than the area of the four tops of the legs and extends for some distance to the front and rear. Glue it into place to form the base of the horse's body.
Cut six slightly curved sections of balsa wood and fit them firmly onto the sides of the body base, three to each side. These will be the ribs of the horse, one of the few details described by the poet Virgil. For extra stability, you may want to use small nails or pins to attach these pieces.
Cut a large solid piece of balsa wood to shape to serve as the neck. The neck should be wider and deeper at the base than at the top, curving slightly forward. Cut a block of balsa into this rough shape using a craft knife or saw, sanding it to emphasize the curve. Glue this firmly to the center of the front end of the body base. A similar, shorter post should go at the center rear.
Build an outer "skin" of individual balsa wood planks, using the ribs, neck and tail post as supports. Glue each plank so that it attaches to a post at either end. Glue a row of planks across the top when finished to complete the back of the horse.
Carve a block of balsa wood into the rough shape of a horse's head. Cut a slot at the base of the head big enough to admit the end of the neck and glue the head onto the neck.
Add detail to your model. You can give your model as much or as little detail as you like. You may wish to carve facial detail on the head using a craft knife, make a tail by gluing lengths of partly-unwound twine to the tail post, or scribe detail into the planks using a pointed instrument such as a compass.
