Before you start building your rubber band gun, you'll need to gather a few basic materials. Here are some of the most common materials used:
Ensure the side plates are perfectly aligned so the trigger and rotor do not tilt or bind during use.
Applying a bit of paste wax or mineral oil to the moving internal parts helps prevent friction and ensures a smooth trigger pull. Common Mechanical Designs
Cut slightly outside the line. You will sand down to the line later. For the barrel channel (where the rubber band stretches), cut slowly to avoid splintering.
