Model bridges can be used as a school project or a fun filled activity for the entire family. Building a model bridge with something as simple as wood craft sticks can help children learn better hand and eye coordination. It's a great way to spend time inside on rainy days. This article will show you how to build a simple bridge suitable for beginners.
Decide on the size of your model bridge before construction begins. If the bridge is to be entered in to a weight contest, be sure to purchase extra wood craft sticks sticks for durability. Most model bridges range between 1 and 2 feet in length. The height can vary as well, depending on preference.
Sketch the bridge on to a sheet of paper to get a better idea of what type of bridge you plan on building.There are many designs to choose from such as draw bridges, suspension bridges or a simple bridge with a slight arch. Amateur builders may want to construct a simple bridge their first time around.
Begin constructing the model bridge with wood craft sticks. Glue several wood craft sticks together to make the length of the bridge. Lay another line of wood craft sticks down parallel to the other and glue those together until both sides are the same length. Once you have reached your desired length, glue a stick from one side to the other connecting the two sides at the sections. This process will hold the foundation in place. If needed, add extra wood craft sticks on the bottom of the foundation to create a "road effect."
Build the sides of the bridge by using a common shape used by many engineers during bridge construction, a triangle. Continue making the triangle shapes and glue each one together until you reach the desired length of the bridge model. Repeat these steps to build the other side of the bridge. Cross brace the triangles when and if needed.
Begin building the top of the bridge model just as you built the sides of the bridge. Glue the wood craft sticks from one side to the other, forming a triangle shape. Press firmly down on to the sticks to make sure the glue is dry before moving on to the next one. It's OK if they are not all lined up perfectly.
Add wire around the connecting points of the bridge for desired effect or durability. Touch up on corners or connecting points with glue.
Hot glue guns can cause serious burns. Don't allow children to use them and wear appropriate safety gear.
