Pen guns are cool DIY projects. Easy to make, they can fit right into your pocket. In this blog, we’ll teach you how to make pen guns with things around your home. Whether you fancy a spring-loaded or rubber band-loaded pen gun, we’ve got it all. So, let’s get your pen guns made!
Take apart the Pen
To begin, twist open a clicker pen with plunger on top. Detach the top part, with the plunger, tube, spring, and ink cartridge, from the pen. Keep all the parts aside. The ink cartridge is the long, white or see-through tube in the middle of the pen.
Change the Tube
Then, grip the lower end of the top piece with needle-nose pliers, and bend the tube inward to narrow the opening. Do this four times around the pen, not near the screw threads to make reassembly smooth.
Put the Pen Back Together
Next, slide the spring and small plastic bit back into the top piece. Hold it upside down with the squeezed end on top. The spring goes back in first, then the little plastic bit goes in the middle of the spring. Push down until snugly stuck. The pressed part of the tube should hold the little plastic in place. If need be, use pliers to bend the edges more.
Put your pen back together, but leave out the ink for now. We’ll need it for ammo later. Connect the main tube and the top part.
How to Load and Fire the Pen Gun
Ready to load? Hold the pen upside-down and slide the ink cartridge through the tip. Make sure it hits the plastic in the top section. Don’t flip your pen or the cartridge could tumble out too soon. If the ink won’t fit, the tip of the pen may need to go. Unscrew it or use pliers to pull it off.
Firing is easy. Just press down hard on the plunger at the pen’s end. Point the pen sideways and aim. But remember: only shoot at targets, not people or pets. We don’t want to hurt anyone.
After the shot, push the plastic piece back and load the ink cartridge again to reset.
Make a Pen Gun with a Rubber Band
Want a different kind of pen gun? Try a rubber band-powered one. Here’s your how-to:
1. Take the pen apart and remove the ink cartridge. If your pen can unscrew in the middle, do that. Otherwise, use needle-nose pliers to get the end and tip out of the main tube. Set the ink aside. Then put your pen back together, making sure it’s open at both ends.
2. Snip the pen tip. Make it a tad wider than the ink cartridge. You’ll need scissors for this. Just put the tip between the blades and press down. Shoot for leaving about a quarter inch (6.4 mm) if you’re just launching the ink cartridge. Cutting the tip should only be done if your pen is plastic. If cutting with scissors proves tough, go for a utility knife.
3. Following that, you’ll need to put a hole in what’s left of the tip. To accomplish this, use a small drill bit. Somewhere between 1/8-1/4 inch (3.2-6.4 mm) should do the trick. Locate the sweet spot around 3/4 inch (19 mm) from the end of the tip. Be careful while drilling, you don’t want a cracked pen.
Here’s how you put together your rubber band-powered pen gun:
1. Get a rubber band and feed it through your recently drilled holes. A good solid knot will keep it in place. A helpful hint if the rubber band won’t go in, a bent paperclip can act as a hook. Use it to guide the rubber band.
2. Next up, the ink cartridge. It goes inside the ring made by the rubber band. Grasp the plastic end of the cartridge. Put it in the center of the rubber band loop. Pull the rubber band to the back end of the pen. This should allow you to put the cartridge’s tip into the tube. Don’t let go of the ink cartridge or rubber band until you’re ready to aim.
3. With the ink settled in the tube, let go! Both the rubber band and cartridge being released will launch it. If you want to shoot again, you’ll need to recover the ink cartridge and load the gun again.
Do mind where you aim your pen gun. Directing it at people or pets could lead to injury. Try to keep any aiming away from faces or heads. Serious eye damage can happen.
In conclusion, creating your own pen guns can be a fun and engaging DIY project. Whether you choose the spring-powered or the rubber band-powered mechanism, remember to prioritize safety and refrain from aiming at people or animals. Enjoy your experience of making and experimenting with pen guns responsibly!
1. Can I use any type of pen for making a pen gun?
Answer: Yes, you can use different types of pens as long as they have a retractable mechanism and can be disassembled easily.
2. How far does the ink cartridge shoot when using a pen gun?
Answer: The shooting distance can vary depending on factors such as the strength of the spring or rubber band and the angle at which the pen gun is held. It’s best to experiment and test different shooting distances in a safe environment.
3. Are pen guns legal to own?
Answer: The legality of owning pen guns can vary by jurisdiction. It’s important to check your local laws and regulations regarding improvised weapons before making or possessing a pen gun.
4. Can I modify the design of the pen gun?
Answer: While the basic design of pen guns outlined in this blog is provided for safety and simplicity, you can certainly modify them if you have the necessary knowledge and experience. However, always prioritize safety and adhere to applicable laws and regulations.
5. Can I use the pen gun for self-defense?
Answer: It is not recommended to use pen guns for self-defense purposes. Improvised weapons are generally not reliable or effective for self-defense situations. Seek proper self-defense training and use legally approved means of protection.
**Remember, safety first! Abide by all local laws when crafting and using pen guns.**
