Using sand paper, thin and smooth the trigger part to ensure smooth operation.

- Cut some tooth picks in half and use the holes in the design to align all components.
- Start from one side and slide all components over the toothpicks with some glue in between.
- Do not forget to position the trigger in the middle.
- Be careful not too put too much glue close to the trigger; if it can not move afterwards it will be useless!
- Use some clamps while the glue is setting.
Shave Off Some Edges, Add Rubber Bands and Start Shooting!

Using sand paper remove the outer edges of the teeth holding the rubber bands and cut away the extending tooth picks; they served their purpose well .Now it's ready to shoot.
Keep it safe, these bands might hurt!.
Suggested improvements:
- Change the name & date of my son's birthday!
- The supports for the rubber band to pull back the trigger should be enlarged somewhat for increased strength.
- The teeth that hold the rubber bands in place should be on a little more oblique surface. Now some type of rubber bands get stuck (other work very fine though).
