Creating a full-fledged paper-machine It begins with the precise folding of modular blocks, which subsequently form a receiver. If you miss the stage of rigid fixation of folds or use too soft material, the finished model will not be able to withstand the tension of the rubber band and will fall apart at the first "shot". That is why the assembly requires attention to each corner and face, since the functionality of the entire structure depends on the density of the adjoining paper.
To implement the project, you will need several A4 sheets with a density of 80 g / m2, glue pencil, scissors and stationery rubber bands. Creation origami It involves the transformation of a flat sheet into a three-dimensional structure with moving elements. Unlike simple static models, the firing option requires the creation of an internal descent mechanism and a channel for the projectile.
The main difficulty is to assemble a store, which should not only imitate the appearance, but also serve as a focal point for the warhead. Modular origami It allows you to create products of increased strength without the use of additional frames. Below we will discuss each stage in detail so that you can assemble a reliable toy capable of accurately shooting paper bullets.
Preparation of materials and tools for assembly
Before you start active folding, you need to prepare the workplace and make sure that all components are available. The quality of the final product depends on how smooth the slices will be and the measurements are accurate. To create gunner White office paper is best suited, as the fold lines are clearly visible on it.
You will need the following tools that will ensure the accuracy of the assembly and the durability of the product. The use of blunt scissors can lead to a jamming of the edges, which will negatively affect the aerodynamics and appearance of the model.
- 📄 A4 paper sheets (density 80-100 g/m2) are the basis for all modules.
- ✂️ Sharp scissors or a stationery knife - for accurate pruning of excess.
- 🧴 Glue pencil or PVA - for fixing joints and strengthening the design.
- 📏 Line and pencil - for marking flat lines of the fold.
- 🔴 Stationery rubber bands are necessary to create a tension mechanism.
⚠️ Note: Do not use too thin newsprint, as it does not hold shape and quickly becomes unusable when playing. Optimal density ensures stability.
To strengthen the design, you can glue two sheets of paper together before folding, which will make the walls of the machine more rigid.
Manufacture of basic modules and trunk
The foundation of any paper structure is the basic modules. For gun-barrel We're going to need to create a few long tubes and rectangular blocks. We begin by creating a main tube that will act as a channel for the flight of a bullet. Accuracy of this step is critical for firing range.
Take a piece of paper and roll it into a tight tube along the long side. The edge must be carefully smeared with glue so that the tube does not unwind during operation. The diameter of the tube should be such that the paper shell moves freely inside, but does not dangle.
Next, we form the body using the technique of adding triangular modules. These elements will cover the central tube, creating a visual image of the weapon. Each module is inserted into the pocket of the previous one, forming a strong chain. The gunbox. It is collected by sequentially stringing such blocks.
The secret of strength
To make the modules sit tighter, make the last fold with effort, almost breaking the paper, but not tearing it.
After assembling the main part of the barrel, check it for internal irregularities. If there are curved corners of paper inside, they will brake the bullet. Perfect. channel It should be smooth. To do this, you can use a pencil or the back of the brush to straighten the internal folds.
Assembly of the store and handle for a convenient grip
Ergonomics plays an important role in the use of paper weapons. Hand the machine It should be comfortable in the hand, allowing you to hold the model firmly during aiming. To create it, we use the multilayer addition method, which gives the parts the necessary rigidity.
First, we form a box of the store. It is a rectangular element that is attached to the bottom of the trunk. Inside it will be a feeding mechanism or just an emphasis for the rubber band. It is important to observe symmetry, otherwise the machine will tilt to the side when shooting.
For the handle, we take several layers of paper folded with an accordion, and wrap them with the main sheet. This creates the effect of a corrugated surface, improving grip with the palm. Mounting the handle to the receiver is carried out using glue and paper tongues-fixers.
☑️ Checking store assembly
Pay attention to the connection of the store and the barrel. This place is under the greatest strain. Mounting point It should be reinforced with an additional layer of glue or paper tape. If the connection is weak, the store may break off at the most inopportune moment.
Descent mechanism and rubber band installation
The most important part of the project is the mechanism that causes the machine to shoot. In our case, we use the energy of elasticity. stationery. The principle of operation is simple: the rubber band is stretched, fixed in the cocked state, and then released, pushing the projectile forward.
To do this, we need to create a hook or hook at the back of the machine. He's gonna be clinging to a rubber band. In the front, next to the cut of the trunk, a small protrusion is made, for which the rubber band clings in a calm state or which serves as a limiter.
| Element | Function | Materials | Feature |
|---|---|---|---|
| Tensioner | Stretching of rubber | Paper/Carton | It has to be solid. |
| Hook | Platoon fixation | Tight paper | Sharp form |
| Rubber | Bullet engine | latex | Medium stiffness |
| Stress | Mounting point | Paper | Reliable fixation |
Installation battle-gum It requires care. It should not be pulled in the assembled state, otherwise the paper will quickly deform. It is optimal when the rubber band is in light tension. The descent mechanism can be implemented as a simple removal of the loop from the hook with a finger.
⚠️ Never point a loaded machine into the face of people or animals. A paper bullet fired at close range can damage the mucous membrane of the eye.
Manufacture of paper bullets and cartridges
The effectiveness of shooting depends not only on the quality of the machine, but also on the shells. Paper bullets They must be light enough to reach speed, but heavy enough to penetrate air. There are several formats of shells for different types of weapons.
The classic version is a tightly twisted cylinder made of a small piece of paper, adjusted to the caliber of the barrel. For our machine, oblong shells are best suited. Their manufacture takes a few seconds, but requires a density of winding.
- ✂️ Cut the paper into small strips 1-2 cm wide.
- 🌀 Roll the strip into a tight tourniquet using a toothpick as an axis.
- 📏 Fit the diameter under the barrel, adding or removing the turns.
- 🧴 Lock the tail with a drop of glue so that the bullet does not unwind.
Composite cartridges can be used to increase the flight range. A shell. It is turned into an additional layer of paper, which increases its weight. However, it is worth remembering that a bullet too heavy can get stuck in the barrel or break the rubber band.
You can store ready-made cartridges in a special department of the store, if you have provided for its increase, or in a separate box. The main thing is that they remain dry, as wet paper loses its ballistic properties and shape.
Decorating and improving the characteristics of the model
Once the functional part is ready, you can move on to the appearance. Camouflage paint Or stylization of real weapons will make the model more recognizable. It is better to use acrylic paints or gouache for painting, as they do not soak the paper as much as watercolor.
To improve aerodynamic properties, you can add imitation of sighting devices. The fly and whole, carved from dense cardboard and glued to the barrel, will help to more accurately guide the machine. This is not just a decor, but a functional element for training accuracy.
If you want to increase the power, you can experiment with the length of the barrel. Longer. barrel This allows the rubber band to work on the bullet longer, dispersing it. However, too long a design will be uncomfortable in handling. The optimal length is 20-25 cm.
The balance between barrel length and usability is the key to creating the perfect paper machine.
You can also add tactical elements such as bipods or a barrel handle. They are made by analogy with the main parts and are attached to glue. The main rule of decoration is not to overload the structure with excess weight, so as not to disturb the balance.
Frequently Asked Questions (FAQ)
Which paper is best used to create a solid machine?
The best choice is office paper A4 format with a density of 80 g / m2. It is flexible enough to fold modules and at the same time strong. To strengthen critical nodes, you can use cardboard for business cards or glue two sheets of paper together.
Why does the gun shoot far or does the bullet get stuck?
The problem is probably calibration. The bullet may be too large for the barrel, or there are bumps and burrs of paper inside the channel. Also check the tension of the gum: if it is stretched, it has lost its elasticity and needs to be replaced.
Can you make a machine that shoots not with rubber bands, but with air?
Yes, there are paper pistol schemes that use a piston system. However, they require more complex assembly, the use of plastic tubes (such as from bushings) and perfect tightness, which is difficult to achieve with paper.
How to mask the joints of paper on the finished model?
To mask the joints, you can use paper tape tone model or cover the product with a layer of primer (a mixture of PVA and water) before painting. This will level the surface and hide the joints of the modules.
