Connecting beams using axles and bushings:

You can also use axles to connect beams. Axles fit through the center of the beams

and can be secured into place using bushings. This technique can also be used toattach wheels to a LEGO structure.

Constructing sturdy shapes:

To construct this simple square, you can used bent beams instead of straight beams.

Bent beams are useful for changing an angle on a LEGO structure.

This triangle can be constructed using 3 straight beams, 2 pegs, and 1 extended peg.

The extended peg is necessary for this construction because of the space between

the beams. There are many other ways to construct a triangle out of beams:
