What is a Pen Gun with Rubber Band, Anyway?
At its core, a pen gun with rubber band is a cleverly modified pen designed to launch small rubber bands. It’s a simple yet effective device, using basic mechanical principles to propel projectiles across short distances. The concept is straightforward: you load a rubber band, cock a firing mechanism, and release it to send the rubber band flying.
The appeal of a pen gun with rubber band lies in its simplicity and accessibility. It’s a project that anyone can try with readily available materials. This DIY nature makes it a perfect entry point for those interested in building small mechanical devices. It’s also a testament to creative ingenuity.
While the exact origins of pen guns are difficult to trace with certainty, the concept has been around for a while, gaining popularity within the DIY and hobbyist communities. Often crafted from repurposed pens, these creations showcase resourcefulness and the ability to repurpose everyday objects. They’re a staple of the “maker” culture, where creativity and hands-on learning are valued.
Understanding the Mechanics: How Does This Thing Work?
To build and appreciate a pen gun with rubber band, you need a good understanding of its inner workings. Let’s break down the mechanics into easy-to-understand steps.
The Pen Body: The Foundation
The pen body, usually the casing of a pen, acts as the primary structural element. It provides the housing for all the internal components and offers a place to hold the device. The type of pen you choose can influence the design and functionality. Sturdier pens, made from materials like plastic or metal, are often preferred due to their durability.
The Firing Mechanism: The Trigger’s Role
The firing mechanism is the critical element that allows you to launch the rubber band. This can vary in design, but the most common type uses a trigger system. The trigger, when pulled, releases the rubber band from its held position, allowing it to be propelled forward.
The Rubber Band Attachment Point: Where the Magic Happens
This component is crucial for securely holding the rubber band before firing. This attachment point can take several forms, such as a small notch, a post, or a simple clip. The position of this point, and how secure it is, will directly affect the firing range and accuracy of the pen gun.
The Barrel (or Guidance System): Guiding the Flight
The barrel, or guidance system, serves to direct the rubber band on its path. In many pen gun designs, the barrel is simply the pen’s internal tube, which helps to maintain the direction of the rubber band during its launch. It’s essential for ensuring a reasonably straight trajectory.
The actual firing process is a sequence of coordinated actions. First, you need to load a rubber band. This typically involves stretching it over a small peg, post, or holding point on the pen. Next, you’ll prepare the trigger. Some designs have a trigger that’s already “cocked,” while others will need manual preparation. Finally, when the trigger is released, the stretched rubber band is disengaged, and this force accelerates the rubber band forward, propelling it along its intended course.
Building Your Own Pen Gun with Rubber Band: The Fun Begins!
Building your own pen gun with rubber band can be an incredibly rewarding experience. With the right materials and some patience, you can create a device that offers hours of entertainment.
Materials You’ll Need to Get Started
- A Pen Body: Choose a pen. Discard the ink cartridge and any non-essential internals. The pen’s casing forms the fundamental structure. A retractable pen can be useful, as the button becomes the perfect trigger.
- Rubber Bands: Select the right size rubber bands for your pen gun. Small, thin rubber bands work well for most designs. Experiment with different sizes to see which ones provide the best performance.
- A Blade (Utility Knife or Exacto Knife): To cut and shape parts. Be extremely cautious while using this.
- Glue (Super Glue or Hot Glue): Used for securing the components to the pen.
- A Small Peg or Dowel (optional): If you are designing a firing mechanism needing a “hold” point for the rubber band. A toothpick can work too.
- Optional Tools and Supplies: sandpaper, a small file, some protective eyewear for safety.
Building Instructions: A Step-by-Step Guide
- Prepare the Pen Body: Empty the pen completely, removing the ink cartridge and any internal components, except the button and spring in a retractable pen. This creates the space needed for the firing mechanism.
- Create the Rubber Band Attachment: Determine where the rubber band will attach. This depends on your design. You might drill a small hole, attach a tiny peg, or notch the pen casing. If you’re using a retractable pen, the button’s mechanism is usually ideal for the firing system.
- Assemble the Trigger (If Needed): If your pen doesn’t have a good trigger, you might need to build one. A simple trigger could be constructed using part of the pen casing or a small piece of plastic, attached to the button in a retractable pen.
- Test and Adjust: Before gluing everything permanently, do a test fit. See if the rubber band attaches securely and can be fired smoothly. Make any adjustments needed at this stage to ensure optimal performance.
- Secure the Components with Glue: Apply a small amount of glue to secure the firing mechanism and rubber band attachment point. Be careful not to apply too much glue, which could impede the moving parts.
- Wait for the Glue to Dry and Test Fire: Wait for the glue to cure completely. Then, test your pen gun with rubber band, load it, and fire! Ensure that the rubber band launches correctly.
Design and Customization: Make It Your Own!
One of the most enjoyable aspects of crafting a pen gun with rubber band is the opportunity to customize it. Here are some ideas to spark your creativity:
- Experiment with Trigger Mechanisms: Try different trigger designs for more complex operations. You can create a trigger that is easier to activate or allows for multiple shots.
- Modify the Barrel: Experiment with the barrel length and material to affect your accuracy and distance. Different designs will give you different experiences.
- Add Aesthetics: Paint or decorate your pen gun with rubber band to give it a unique look. Add your personal touch and make it stand out.
- Improve the Sighting System: Increase your accuracy by creating a simple sight. A small piece of plastic or a notch on the pen can serve as a basic aiming system.
- Add a Safety Mechanism (Optional): While pen guns are usually safe, adding a small clip or other safety device for storage can improve the safety of your project.
Responsible Use and Legal Considerations: Safety First!
While building a pen gun with rubber band is a fun hobby, it’s crucial to practice responsible use at all times. Safety is paramount.
- Always Use Eye Protection: Wear safety glasses or eye protection while operating the pen gun and when anyone else is nearby.
- Choose Safe Targets: Never point the pen gun at any person or animal. Instead, target soft objects like cardboard boxes or sheets of paper.
- Be Aware of Your Surroundings: Always be conscious of your surroundings. Ensure there are no valuable items or breakable objects nearby.
- Supervision: Make sure you are supervised by a responsible adult if you are a minor.
- Proper Storage: When not in use, store the pen gun in a safe location, away from children and anyone who might misuse it.
Legal considerations vary greatly depending on where you live. It’s essential to research any local laws concerning these types of devices. Always be aware of your state and local laws. While pen guns are generally considered safe, the specific legal status may vary. This article does not provide legal advice. Always be informed.
Troubleshooting and Common Problems: Solving the Issues
Even with careful construction, you may encounter some problems. Here’s a look at some common issues and how to overcome them.
- Rubber Band Snapping: Using bands that are too old, of poor quality, or have worn out after use. Change the rubber bands and try again.
- Firing Mechanism Problems: The trigger may fail to function. This could be caused by misalignment or glue that prevents the movement. Examine the firing mechanism carefully, adjust the parts, and, if necessary, apply a bit of lubrication to get the mechanism to work correctly.
- Inaccurate Shooting: Consider the attachment points of the rubber band. Make sure the firing mechanism is designed for accuracy.
