Lego Trusses


The problem that many beginners face when they are starting to build Lego truss bridges is the issue of building triangles. Legos are a primarily rectangular medium, so some thought needs to go into the construction of sturdy, angled frameworks.

A very commonly-used technique is to use Lego Technic elements to construct trusses. 1xN bricks with holes are placed next to each other and 3L pins are used to place 1x4 with holes behind them, to hold them in line. The protruding end of the pin is used to place bars on angles with other brick assemblies, allowing bars at angles. While this approach is easy and requires only pins and bricks with holes, it doesn't allow the diagonal members to meet in true truss-bridge fashion. This approach will work for smaller bridges, but different ones will be needed for structures carrying much larger loads.
