Hello Instructabrains! Welcome to my tutorial on the Easy Pen Shooter as the title suggests. Unfortunately this instructable requires a specific type of pen, but it is fairly common one you can get if you are in the US, but I am not sure about other countries.
Step 1: Obtain a Pilot G-2
The first step is to obtain a Pilot G-2 Pen. Go to your local office supplies store and get some of this specific type. If other types work please comment their names.
Step 2: Gut the Pen
What you want to do with gutting the pen is to unscrew the main body of the Pen. This is a fairly easy step. After you have done that take the pen cartridge out and use it to push in the plunger part and remove those pieces. Finally, the last step is to remove the spring from the front main body part of the pen. To do this, take the front part of the main body of the pen and tap it heavily on your table or workshop surface.
Step 3: Assemble the First Part
In this step you will assemble the main firing mechanism. All it is is the spring sandwiched between the plunger and the part it is connected to in the pen as shown in the picture.
Step 4: Final Assembly
Insert the firing mechanism into the back main pen tube assembly plunger first. Then use the pen cartridge to push it down, as shown in the picture.
Step 5: Firing
To fire the pen shooter, push in the plunger and the piece at the other side of the firing mechanism will shoot out.
Step 6: Creativity!
If you have any comments, questions, or ideas please post them in the comments. Get creative with this project by modding the ammo or finding other ways to tweak it.
