Q:

How do you build a model bridge?

A:

Quick Answer

To build a model bridge, first decide which bridge design is desired, then use a piece of grid paper to draw the bridge to scale. Gather skewers and string to begin making the bridge. Use the grid paper diagram and a pair of garden sheers to trim the skewers to size. Connect the skewers with string; for difficult joints, wood glue may be required. Place a piece of cardboard over the bridge, and press on it to test its strength.

If the skewers hold under light pressure, the build is successful. If not, retie the strings to strengthen the bridge. If rearranging the strings does not work, try building the bridge base around a weight bearing surface, and attempt to provide extra support in the area.

If glue is required to hold some of the joints, be careful not to use too much. Employ a hot glue gun or tacky glue for the task; white glue does not hold the skewers together. Any sharp skewer edges can be trimmed with the garden sheers or a utility knife.

Styles of bridges can vary. Options include the Warren, Pratt, Howe and Arch. Another option is to design a unique bridge using inventive connections and designs.
