The fins are what help stabilize the rocket in flight.  The following steps show how to cut and sand the fins to prepare them to be attached to the rocket.

2.1.Carefully cut the Model Rocket Fins out of the Laser-Cut Balsa Sheet.

2.2. Sand the rough edges of the fins to remove any burrs.

2.3. Align the sides of all four fins, hold them together and sand the base of the fins (This just ensures that the fins are flat where they attach to the rocket).
