Introduction
What Are the Jaws of Life?
The “Jaws of Life” is a hydraulic rescue tool widely used by emergency rescue personnel to assist in extricating people trapped in wreckage. Whether it’s a car accident, a collapsed building, or any other situation where individuals are trapped within a confined space, the Jaws of Life can be a lifesaver—quite literally. The tool works by exerting immense pressure to cut, bend, or spread metal, allowing rescuers to quickly and safely free trapped individuals.
Why is it Important?
The importance of the Jaws of Life cannot be overstated. In emergency situations, every second counts. Traditional methods of extraction can be time-consuming and may even exacerbate the injuries of the trapped individuals. The Jaws of Life, on the other hand, allows for quick and efficient rescue operations, minimizing the time between the accident and medical treatment.
About This Project
In this blog post, we aim to bring the concept of the Jaws of Life closer to home—literally. We will guide you through creating your own miniature hydraulic Jaws of Life model. This is not just a fun and educational DIY project; it also provides a hands-on understanding of the mechanics and principles behind this life-saving tool.
Two Methods, One Goal
We understand that not everyone has access to the same materials or tools, so we’re offering two different methods to build your Jaws of Life model. The first method is a basic model that utilizes everyday items like cardboard and syringes. The second method is a more advanced model that requires a specialized kit. Both methods aim to demonstrate the hydraulic principles that power the real Jaws of Life.
So, whether you’re a student looking for an exciting science project, a teacher aiming to bring practical learning into the classroom, or simply a DIY enthusiast, this guide is for you. Let’s dive in!
Method 1: Basic Jaws of Life Model
Materials Needed
To get started with this basic model, you’ll need the following materials:
- Puncher
- Eraser
- Pencil
- Craft knife
- Drilling machine
- Glue gun
- Cardboard
- Plastic tube
- Two syringes
- Four ice cream sticks
- Five nuts and bolts
Gather all these materials before you begin to make the process smooth and efficient.
Preparing the Materials
Step 1: Draw the Pieces
Using a pencil, draw the shapes needed for the project on a piece of cardboard. These shapes will form the base and jaws of your model. Make sure to measure and mark accurately to ensure all pieces fit together well.
Step 2: Cut Out the Pieces
Once you’ve drawn the shapes, use a craft knife to carefully cut them out. Always remember, safety first! Make sure to cut on a stable surface and away from your body.
Assembling the Base
Step 3: Cut the Stable Part
Identify and mark the portion of the cardboard that will serve as the stable, non-moving part of your model. Use the craft knife to cut this piece out.
Step 4: Attach the Syringe
Use a glue gun to attach one of the syringes to this stable part of the cardboard. Make sure it’s securely in place before moving on to the next step.
Assembling the Jaws
Step 5: Punch Holes
Take the pieces that will serve as the jaws of your model. Use a puncher to create holes where you’ve marked. These holes will be used to attach the jaws to the base.
Step 6: Attach the Jaws
Use nuts and bolts to attach the jaws to the stable part of the cardboard. Make sure they are tightly secured but still able to move freely.
Hydraulic System and Final Touches
Step 7: Attach the Plastic Tube
Take the plastic tube and attach it to the syringe that’s fixed to the cardboard base. This will serve as the hydraulic system of your model.
Step 8: Test the System
Fill the second syringe with water and a few drops of food coloring for visibility. Attach this syringe to the other end of the plastic tube. Test the hydraulic system by pushing and pulling the syringe. If everything is set up correctly, you should see the jaws open and close.
And there you have it! You’ve successfully created a basic Jaws of Life model using everyday materials. This project not only teaches you about the mechanics of hydraulic systems but also gives you a hands-on experience of how this life-saving tool works.
Method 2: Advanced Jaws of Life Model
Materials Needed
For those looking to take their Jaws of Life model to the next level, you’ll need the following materials:
- Pencil or pen
- Craft knife or scissors
- Lego bicycle dude (optional, but adds a fun element)
- Curious kit, which includes:
- Housing
- Jaws
- Linkages
- Adapter plate
- PVC tube
- Syringes
- Wood glue
- Paper stick
- Elastic bands
Make sure you have all these components ready before you begin.
Preparing the Materials
Step 1: Open the Curious Kit
Open your Curious kit and lay out all the components. Familiarize yourself with each part as they will all play a crucial role in your advanced model.
Step 2: Separate the Jaws and Linkages
Use a craft knife or a pair of scissors to carefully separate the jaws and linkages from their connected states.
Step 3: Prepare the Holes
The linkages will have holes that may be a bit tight. Use a pencil to gently widen these holes to make a snug fit for later steps.
Assembling the Base
Step 4: Glue the Housing Pieces
Take the middle housing piece and glue it to the bottom housing piece using the wood glue from the kit. Make sure they align perfectly.
Step 5: Insert the Axles
Your kit should include paper sticks that will serve as axles. Insert these into the cardboard slots on the sides of the housing.
Assembling the Jaws
Step 6: Insert the Jaws
Take the separated jaws and insert them into the outer holes of the axles in the housing. Ensure they are evenly placed.
Step 7: Complete the Housing
Glue the top housing piece to the middle housing piece. This will encase the jaws and axles.
Hydraulic System and Final Touches
Step 8: Attach the Adapter Plate
Your kit should include an adapter plate. Attach this to the 5ml syringe using wood glue.
Step 9: Insert the Syringe
Insert the syringe with the attached adapter plate into the housing. Make sure it aligns with the jaws.
Step 10: Secure Everything
Finally, use elastic bands to secure all the components in place while the glue dries.
Congratulations! You’ve just completed an advanced Jaws of Life model. This model is not only a great educational tool but also a more realistic representation of the actual life-saving device.
Testing and Safety Tips
Adult Supervision is a Must
While this project is designed to be educational and fun, safety should always be your top priority. It’s crucial to have adult supervision, especially during the cutting and drilling stages. A responsible adult can ensure that the tools are used correctly and safely.
Test Before You Trust
Before you consider your project complete, it’s essential to test the hydraulic system. For both methods, fill the syringe with water and a few drops of food coloring to make the liquid visible. Push and pull the syringe to operate the jaws. If they open and close as expected, you’ve successfully built a working model!
