Homemade powerful slingshot drawings. Five ways to make a slingshot at home. Slingshot technique

After the invention of rubber. Abroad, they use a slingshot to hunt birds and small animals - hares, rabbits and other raccoons.

Those slingshots that are sold in Russia are very weakened and are designed for throwing bait while fishing, in order to bring the slingshot into combat condition, you need to change the rubber band to a more powerful one.

How to make a slingshot with your own hands

The most simple slingshot- This homemade slingshot made of wire.

Here they are in the photo above. Such a slingshot is made from ordinary aluminum wire for electrical wiring; it was taken from a construction site; you only need a little, and in those days there were countless scraps lying around the construction site.

The wire is bent, the insulation in the upper part is carefully trimmed in a circle, removed, an elastic band pulled from underpants or taken from a rubber motor model is put in, and the insulation is put back.

Slingshot bullets were made from the same aluminum wire using pliers or wire cutters. In the evening it was possible to make a couple of hundred bullets, which were shot in a day.

Homemade slingshot made of wood

The easiest way to make a wooden slingshot is from a Y-shaped fork in a tree. You will need a hacksaw for metal or wood and a knife. The cut part must be cleared of bark and dried. It would be good to dry for about a month, but as children we didn’t bother with this, how will it dry out? outer part the slingshots, after removing the bark, were put into action.

What should we do there? Cut the grooves for attaching the elastic and secure the last one, and also put on a leather jacket for shells. Delov for 10 minutes.

You can cut a homemade slingshot from multilayer plywood, Any will do a piece 2-2.5 cm thick. You shouldn’t take anything thinner, it may break if the rubber is strong.

Metal slingshot

You can make slingshots from metal, look at the photos of slingshots below - what they are not made from!

The principle of making slingshots is the same - cut out Y figurative form, put on the rubber band and the slingshot is ready to shoot. You can braid it with lace, paracord or soaked leather, soak it so that when it dries, the skin tightens and tightly braids the slingshot.

How to shoot with a slingshot

Usually they shoot pebbles from a slingshot; it is advisable to select rounded pellets. Just keep in mind that different weights of pebbles also result in different behavior of the projectile in flight. However, as a child they fired 200-300 rounds every day and from 15 meters they hit a bottle with any stone.

But for accuracy competitions they used balls from bearings. Whoever won the slingshot could go and collect all the balls from the targets, this was the prize, because it was difficult to get balls from the bearings.

We shot with a slingshot and with nuts, they also fly well and predictably to the target, but the balls are still better.

Today you can buy steel balls for shooting from a slingshot and a homemade crossbow in a hunting store. The balls are the same.

Many people complain that it is difficult to shoot from a slingshot and that it is impossible to hit a bottle with it at 10 meters. Laugh in their faces! Shoot 100 shots every day and in a month you will be able to shoot down from 10 meters Matchbox from 10 meters 9 times out of 10 shots!

Where to get rubber for a homemade slingshot

As children, we used rubber from inner tubes of cars and bicycles - we had to carefully, without burrs, cut the harness to the required thickness. It’s not easy, we cut it with scissors, moistening them in a diluted soap solution (it cuts better, less likely to cause a burr).

Today you can buy a ready-made rubber cord. Only in hunting stores it is weak. It is better to use a cord to tighten glider models.

You can buy a harness for a slingshot.

6-fold stretch, designed to tighten the airframe to 5 kg. If you fold the harness in half and place it on each side, then 4 “lines” will give a tension that is enough to launch 20 kg to a height of 50 meters :)

The calculation is, of course, very ironic, but my converted slingshot with this rubber easily breaks champagne bottles at a distance of 15 meters. Look at what kind of rubber cord was installed on it normally (the black one is on the bottom) and what coil (10 meters) was left for use in other entertainments!

Just as interesting.

Almost every boy once approaches his father or older brother with a question about how to make a slingshot. At home, this toy weapon can be made from the most different materials. There are options for wooden, wire, and plastic slingshots. You can even make a slingshot out of plastic bottle. The article discusses various options moreover, at home.

“Shoot” made from rubber bands on fingers

This is the simplest slingshot, which only requires an elastic band. Having made a loop at each end, they need to be put on the index and middle finger non-dominant hand (for right-handers - on the left, for left-handers - on the right). That's all! We take dowels twisted from paper, fold them in half, place them with a fold on the elastic band, pull them tight and release them. Here's how to make a slingshot at home in a few seconds. Its convenience is that you can remove the rubber band from your fingers instantly, and hiding the rubber band is quite easy. in the event that adults suddenly start looking for the one who did the mischief...

How to make a slingshot at homefrom the branch?

To make such a weapon, you can find a twig shaped like the letter Y - a spear. Having removed the jags and irregularities, so as not to damage your hand during the game, we attach an elastic band to the upper corners of the slingshot. For convenience, you can carve recesses in the attachment points so that the elastic does not slip off. Or you can drill holes and secure the elastic by threading it through the holes. The most comfortable slingshot is the one with a piece of leather attached in the middle of the elastic band. It is necessary to hold a pebble or ball.

How to make a slingshot with your own hands from wood?

There is a “gift version” of the slingshot, that is, a souvenir one. This thing can be made of a stationary type, that is, with a stand. Then you should consider the option of a stand. home distinguishing feature of this toy is that the backbone of the slingshot has original form. This could be a funny face of a bear cub with its front paws raised up, or a bunny with ears used to attach an elastic band. Or you can make a slingshot from an ordinary rolling pin with handles. All you have to do is saw off a part about 15 cm long from it, carve a notch in the thick end (opposite from the handle) through which a dowel or pebble will fly out, and make holes on the protrusions for attaching the elastic.

How to make a homemade slingshot from wire?

You can use a solid wire frame as the backbone of a child's weapon. Branching in this case, there is no need to make the shape of the letter Y. In this case, the metal is bent at a right angle by a step, then folded in half and the second part of the frame is made symmetrically. The lower part, where the wires are connected together, is wrapped with electrical tape, and loops are made on the upper diverging ends for attaching an elastic band.

How to make a slingshot from a plastic bottle?

You can use a regular balloon or a pharmacy fingertip and an empty plastic lemonade bottle. Remove the cap from the bottle and cut off 7 cm, measuring from the neck. A ball or fingertip is pulled over the neck and secured tightly with thread or wire. You can shoot from this device with a pen, pencil, or even piece of branch inserted into the neck. Hold the handle with your hand through the rubber of the ball or fingertip, pull back the rubber and suddenly release it.

The slingshot has long been perceived as nothing more than an attribute of defense and attack by all the boys in the yard. Behind easy way Its model, which you can make with your own hands, has become a favorite toy and even a weapon among adult men for small game. Currently, the slingshot is still very popular and has unconditional respect among boys different ages. Despite its apparent simplicity, its manufacture can be different from each other, as well as the material used.

It is a mistaken opinion that a slingshot is just a small mini weapon for hooligan boys. Professional slingshot in the hands of a fighter it can become a real weapon with which it is not scary to go to the enemy. To obtain such a weapon block, specialists use the highest quality materials: titanium, carbon fiber. Supplemented with a laser pointer or red dot sight, it was often used to restore order during riots. More fighting slingshot used as the first “assistant” when firearms were not used appropriately. The purpose of the slingshot is not specified; everyone uses it for different purposes. Later we will describe ways in which you can do without a slingshot, but with its help make the work easier. Let's look at what a slingshot is for, how to make it yourself, and figure out which material is preferable in everyday use.

A slingshot is a throwing weapon in which the projectile acquires kinetic energy potential energy stored in a stretched rubber band.

Origins of the slingshot

The meaning of the word “slingshot” itself, according to some unreliable sources, comes from the word “horns”. Indeed, they do have certain similarities. It is often compared to a catapult, only in this case it is miniature device. Like many inventions that have survived to this day, the slingshot was created by Leonardo da Vinci. The original device was a slingshot without rubber, and instead there were special rollers on the axles. Inside there were springs with pulleys. A cord is attached to them, when stretched the springs stretch and create conditions for an accurate and long-range shot. Over time, this mechanism was replaced by a simpler one replaced by rubber.

What does a slingshot consist of?

In appearance, the slingshot does not have a complex mechanism, however, it is divided into several important units:

• The body of the slingshot, consisting of wood or less often metal;
• A throwing tourniquet that accumulates energy;
• Boot, heel or saddle. Serves to hold the projectile. It may be missing if the projectile protrudes in the form of metal brackets.

A slingshot, similar to the standard model, is mainly made of wood (walnut, cherry, elderberry). For perfect shape young branches are taken as a basis in the shape of the letter Y, the young “horns” are tied together and left in this form for approximately two months. After which the shape of a regular slingshot is formed.

A serious approach to the manufacture of a slingshot determines the accuracy in the symmetrical placement of the horns relative to the handle of the base.

After two months, the slingshot is cut down. To purchase the device strong look, it should be cleared of the top layer of bark and dried, wrapped in material, for about two weeks. The slingshot is then fired over an open flame. From this point on, the ideal thickness and surface are achieved using sandpaper.

Correct selection of material

• Slingshot body. Having become a favorite among young men, slingshots today are made of metal, plastic, wire, wood, and cardboard. Naturally, the most durable material from the above is metal, and then wood. It’s just that a slingshot made of wood is more common due to the fact that the complexity of working with metal cannot always be used at home. Plastic is no less durable, even mechanical stress is not harmful to it. Cardboard is only suitable for playing with children, but do not underestimate its power for throwing bullets.
• Choosing a rubber band. According to numerous reviews, the most suitable option is rubber sheathing of cables. The simplest option is a medical tourniquet, but only because it can be bought at a pharmacy. Many people recommend a Martens bandage, a GP 5 gas mask. A latex surgical drainage tube is considered very durable and malleable, but it is very difficult to get. More simple options used by those who need a slingshot only for the game, for example, rubber from a ball or a bicycle tire is used by young men. It is affordable, and its throwing properties absolutely meet their needs.
• Kozhetok. Almost always he always has rectangular shape. The material from which it will be made must be durable and provide reliable wear resistance. Usually it is leather, less often suede, dermantin.

Which projectile to choose

The good thing about a finished slingshot is that you can pick up shells for it even on the street; these can be ordinary stones. The size and shape are chosen by the owner himself for personal reasons. If you want to increase destructive power, speed, and impact when thrown, then opt for special metal bullets purchased in stores. These can be steel balls, lead shot, chopped lead, or drawing lots.

A simple option to make a slingshot with your own hands

• A strong slingshot will be no worse than one bought in a store, if you approach your homemade product responsibly. Find a branch that looks like the letter Y. It is advisable to use sizes that are between 15 and 20 cm long.

1. To ensure the branch is strong and secure, make sure there are no cracks or chips before breaking it from the tree. It’s okay if there are small scratches on the branch; they can be easily cut off with a knife;
2. The bark will become redundant, so it is often removed. This is done for aesthetic reasons.

• The best option would be a fresh branch. But the moisture it contains is excessive, otherwise the structure will lose reliability. How to dry it. The easiest way is to wrap it in material and dry it in microwave oven. Use the correct step-by-step instructions:

1. Wrap the future slingshot in a small towel. Place in the microwave and leave on the highest setting for a few seconds.
2. The stick will create a hissing sound, when it stops, put it down again for a few seconds and do this several times.

The photo below shows what can happen if a stick is placed on for a long time no towel. It may turn black or even catch fire. So be careful, watch what you do.

• Let's move on to creating notches. For this you will need a construction knife. Make cuts on the top of each branch, as shown in the photo.

• Let's move on to the choice of tires. IN in this example a medical tube will be used, you in turn can use another rubber band, for example, a tourniquet, rubber from an old ball or a bicycle inner tube. The diameter is 80 mm, and as for the length, you decide what it should be. The traction force depends on this. The shorter the band, the stronger the throwing. Don’t forget that it still needs to be stretched, so you shouldn’t make it too short either. Once the length is chosen, cut the two tubes in half and tie the end of each to its own notch.
• Tie a piece of dental floss around the tube. The thread will tighten the tube and make it strong.
• Let's move on to creating the skin. It is not difficult to cut it from any durable fabric, it’s better if it’s leather. A 10x5 rectangle should have a small hole on each side (0.8 - 1.20 cm). Later we will thread the traction tube through these holes.

• Now everything is simple. Pass each end of the rubber tube through the holes. Make a knot on each one. Manipulation with dental floss can also be used in this case, the structure will become much stronger.
• The slingshot is ready. Practice using your new slingshot to shoot down any inanimate object, train your eyesight and accuracy.

This example is more suitable for the amateur method of throwing stones or other small equipment.

An original slingshot for homemade work with children

It's no secret that most children who like slingshots are boys. Therefore, you can use this master class as a development activity for your son or grandson. To start the process you will need the following tools:

• Tube from toilet paper. You'll have to prepare in advance; you won't unwind a whole skein;
• Insulating tape;
• Pencil;
• Rubber;
• Scissors.

1. Take a cylindrical shape of toilet paper and cut it vertically, this will make it easier to roll. Roll it into a stick and wrap it with electrical tape.
2. At the end of a cardboard stick, make a hole the diameter of a simple pencil. Insert it, turning it round and round.
3. Let's move on to the skin. To make it you will need durable cardboard. Using scissors, cut out a rectangular shape and use a hole punch to make holes for the elastic along the edges.
4. You determine the length of the elastic yourself; if you don’t stretch it on one side only, it is approximately equal to the length of a pencil. Insert it into the holes of the leatherette, tying each end into a knot. And twist the other end onto the end of a pencil and tie tightly. This way you will get a slingshot that you can play with at home, and you can come up with anything you want in the form of bullets. For example, soaked paper from which you form bullets with your fingers.

Slingshots made of cardboard will be stronger when the handle, which bears the main force, is strong. Therefore, it is better to additionally wrap it with adhesive tape.

Rules for using a slingshot: caution

Some types of slingshots are considered melee weapons, but even if the slingshot you buy is legal to use everywhere, this does not open up the boundaries for you to shoot animals and people. Do not hold the slingshot at eye level and do not aim at the eyes of the person standing next to you; even a small bullet can lead to dire consequences.

How to make a hunting slingshot with your own hands

Makes an ideal slingshot correct design and it doesn’t matter what material it consists of. The elastic band, in turn, ensures fast and accurate flight. To find the required forked branch you will have to work hard, but you can use a jigsaw. In order to make a slingshot for hunting we will need:

• Jigsaw and wood or ready-made slingshot branch;
• Sandpaper for sanding;
• Rubber;
• Construction knife;
• Drill;
• A small piece of leather.

When the slingshot-shaped branch is in your hands, we begin sanding away the tree bark. If you decide to use a jigsaw, know that the handle should not be flat, and the horns must be made the same in distance between each other and in length.

We cut out a flat flexible plate from leather. We make holes on the sides for the elastic and thread it through, tying it at the ends.

To attach the elastic band to the slingshot, you can use a drill and make corresponding holes at the ends of the horns, or you can make cuts with a knife. Both methods are welcome. The main thing is that the knot is strong.

The horns should be at the same angle from the handle. And the handle, in turn, should not be too thin, since you will have to shoot from it often, the design must be durable.

You can expand your imagination and create a completely different type of slingshot using a plastic bottle. You will need:

• Plastic bottle;
• Construction knife;
• Rubber band for money;
• Finger cap.

Cut off the top of the plastic bottle. We don't need a lid. We put the fingertip on the neck and tighten it with an elastic band. That's it, the slingshot is ready, all that remains is to put the projectile inside and take aim.

The best stretch for a slingshot is 80% of the resting length. A good option for the throwing harness is latex.

Pocket Weapon: Where to Use a Slingshot

The first thing that comes to mind for a person who is not interested in this type of weapon is the boys playing in the yard. But the slingshot has a much broader horizon and its properties very often become useful at home. Let's figure out where you can use a pocket weapon.

1. Anyone who has a vegetable garden or garden knows that very often it is attacked by petty thieves such as crows and other types of birds. You can save yourself with a scarecrow, but if it doesn’t help, you can drive away the ill-wishers with a slingshot. Just be extremely careful so that if you miss, there is no other person far away from you.
2. “The pear is hanging - you can’t eat it” - this is how the well-known riddle begins, but today is not about it. The slingshot can be used to aim to hit the fruits that are located at the very top of the fruit tree.
3. The tourist needs to give the slingshot its due. A foreign country is full of unexpected surprises, unless, of course, you are aware in advance of some of its dangerous zones. In this case, a slingshot can be useful in scaring away wild animals and protecting yourself from dogs. If you decide to stay overnight in the forest for a few more days, then this is the perfect time to try your weapon on small animals. Such hunting does not require licenses or special permits.
4. Anglers often use a slingshot to throw food into the distance of a reservoir.
5. With the help of a slingshot they develop accuracy. Using it for such purposes, in a very short period of time, you will shoot down targets from a very long distance.

As you can see, a slingshot is a very useful throwing device that is accessible to every person. You can put it in your pocket and carry it with you as a protective device.

How to make a slingshot for fishing

Perhaps it will be a discovery for many that slingshots are used to feed fish at a distance of 30-40 meters from the shore, but not for the fishermen themselves. This simple device is popular nowadays. Characteristic feature for the slingshot used in the fishing industry is rubber. The force of flight depends on its rigidity. The softer the rubber, the closer and vice versa. In fishing stores you can find two types of slingshots: for crumbly mixtures of complementary foods and complementary foods in lumps. Consider the master class of a slingshot, which in fact will turn out to be no worse than the factory version.

We will need:

• Pezzer catheter;
• Strong thread;
• Branch resembling the letter Y;
• Scissors, knife;
• A small piece of leather.

1. We clean the finished branch from the bark. You can do this with a knife or take sandpaper.
2. We get rid of existing moisture using a microwave, after wrapping it with cloth or drying it for about a month, if there is time for this.
3. We cut small transverse grooves in the upper axis of the branch.
4. We tie each end of the catheter with a thick thread to two holes.
5. From the leather we cut out the required leather jacket shape.
6. Make holes on the sides and attach the ends of the catheter to them. We fasten tightly with thread.

To ensure maximum flight power, it is recommended to hold the slingshot vertically. Make the balls the same, of the same weight, so that you know the approximate footage from the shore. The elastic band should be pulled as tight as possible.

They say that even a stick shoots once a year, so take the slingshot seriously. Use it for its intended purpose, namely: to hit objects to develop accuracy, for game, for feeding and for helping with housework.

Slingshots - multifunctional throwing devices small size. Long years They are used for a variety of purposes, ranging from hunting to accuracy games. Slingshots can vary in size and design, as they can be made from a number of various materials. However, all slingshots have common features: A strong frame, rubber bands and projectiles that are sent flying when the rubber band is pulled and released.

Steps

Classic wooden slingshot

Find a strong Y-shaped spear. Pay attention to the branches lying on the ground that can be broken off or trimmed to the desired shape. Branches from almost any tree will work for your slingshot, as long as they are strong enough to hold their shape when you pull your slingshot. However, for convenience and simplicity, it is best to use a spear about 15–20 cm long with branches 2.5–5 cm thick.

• Look for branches on the ground in a wooded area. There you will have a noticeably greater choice among suitable materials.
• If you prudently remove the flaking raw or mossy bark from the slingshot, you will get a slingshot that will be more convenient to hold in your hands.

1. Dry the spear. Hang the found branch over a heat source, such as a fire or burner, and turn it over periodically. Dry the branch for several hours. As it warms up, it will gradually come out of the branch. excess moisture. This is necessary so that the slingshot bends less at the time of the shot.

   Make grooves at both ends of the fork. Take a pocketknife or a sharp stone and scrape out shallow circular grooves at the ends of the spear. Each groove should be located about 2.5 cm from the ends of the forks. The grooves will ensure reliable fastening of the rubber bands (weights) with which you will shoot.

   • If you make the grooves too high, the pressure of the tensioned rubber band may cause the slingshot to break. If you make them too low, then the shells you shoot may constantly cling to the base of the fork.

2. Cut the elastic for the slingshot weights. Any thick, springy material you have on hand can make an effective throwing mechanism. Thick rubber bands or strips of latex and even medical tourniquets are all great options for making a fairly powerful slingshot. Having picked up suitable material, fold it in half and cut it to get two identical strands. Each string should approximately correspond in length to the length of the fork of the slingshot.

   • The specific length of the draw weight will depend on your preferred shooting style, as well as the materials you are working with. Shorter pulls will allow you to make more powerful shots, but it will be more difficult to draw the slingshot.
   • Longer strings will allow you to adjust the slingshot to your liking or even completely redo it if you make a mistake somewhere.

3. Attach the heavy ropes to the spear. Take one of the two strings and wrap the end around one of the grooves on the slingshot that you prepared earlier. Tie the tie securely in this place. Do the same with the second weight. Trim the tied ends of the strings shorter so that they do not get in the way. Your homemade slingshot is almost ready!

   • To ensure that the slingshot shoots accurately, make sure that its lengths are as equal as possible. Otherwise, your weapon will turn out skewed.
   • Check the tension knots for strength. If one of them comes undone at the moment of firing, the slingshot can whip your arms quite painfully.

4. Make a skin. Take a scrap of durable material and cut a strip about 10 cm long and 5 cm wide from it. At a distance of about 1.5 cm from the ends of the strip, make holes through which the free ends of the ties can be threaded. The resulting skin will serve as a nest for your shells, in which they will sit securely immediately before firing.

   • It is best to use durable material having some resistance, such as leather or thick burlap.
   • To make holes in the skin, use the tip of a pocket knife or similar object. You can also simply make slits in the material, but they can break after just a few shots from the slingshot.

5. Tie the skins to the ties. Insert the free end of one string into one of the holes on the leather cover. Tie the string in a knot on outer edge skin. Repeat the same with the second weight. Now the slingshot trigger is a single unit and consists of a skin in the center and two weights attached to its ends.

   Piston slingshot made of cardboard tubes

   Make a longitudinal cut on a cardboard toilet paper tube. Take scissors and cut the toilet paper tube on one side so that it can be unrolled into a sheet. You only need to make one cut, as the tube should remain an intact sheet piece.

6. Roll the cardboard into a narrower tube and secure with tape. Place the edges of the cut cardboard tubes on top of each other, and then roll it up the way people usually roll newspapers. As a result, the tube should become half the diameter it was before. Wrap a long piece of tape around it to secure it, leaving only an inch of cardboard sticking out at one end.

   • This part will serve as the internal piston of the slingshot, which you will use to launch projectiles.
   • The inside diameter of the tube should be small enough to hit the projectiles you intend to shoot without allowing them to slip through. It will be helpful to compare the dimensions of these parts before you tape the tube together. If it is too wide, twist it a little tighter to get the right size.

7. Make two holes on opposite sides of one end of the tube. These two holes should be large enough to fit a pencil. Place them at one end of the tube strictly opposite each other, and not at opposite ends. In order not to skew the holes relative to each other, it will be more convenient to look at the tube from above.

   • To carefully punch holes, use a hand-held single hole punch. But if you don't have a hole punch, you can make holes with scissors or the tip of a pencil.

8. Insert a pencil into the holes of the cardboard tube. Insert a pencil into one hole of the piston and out the other. Place the pencil exactly in the middle. To do this, adjust it until the ends of the pencil of equal length stick out on both sides of the tube.

   • It's best to use a short, thick pencil, as you'll be less likely to accidentally break it.
   • Be careful not to damage the holes in the cardboard when inserting the pencil. They should only be large enough to accommodate a pencil. If one of the holes breaks, rotate the tube and make two new holes in it.

9. Take the second whole toilet paper tube and make a series of cuts on it. Using a pencil, draw two vertical lines 1.5 cm deep from one end of the tube. Leave a finger-width of space between them. Turn the tube and make two more similar marks on the opposite side of the same end. Then take your scissors and carefully cut the cardboard along the marks.

   • This tube will be the outer cylinder of the piston slingshot, housing the thinner piston you made first.

10. Hook a money rubber band on both sides of the tube. Hook the elastic bands over the paired cuts, lowering them to the very bottom of these cuts. In order for this type of slingshot to shoot properly, you will need to use an elastic band on both sides.

    • You will achieve the best results if you take two identical rubber bands. If you don't have special choice, try to check that the rubber bands used are the same size and thickness.

We all made slingshots as children. First, you find a suitable branch on a tree, break it off and attach an elastic band “from your panties”. Such stags were not powerful and very primitive, but this was enough for us. We will make a compact and fairly strong steel slingshot, it can be good entertainment for you.

If the slingshot is powerful, then your hand will get tired when shooting, and significant pressure from the thin handle will feel unpleasant. This can be partially solved by using a rest, thanks to it you can aim better, your hand will hardly shake, and there will be no strong “dents” left after the hunt.

All potential energy stored in the elastic band that we tighten before shooting. IN modern world There are countless materials that are perfect for slingshots. You can buy a good and high-quality tourniquet at the pharmacy, yes, don’t be surprised, they sell various medical supplies that we can use as a throwing tourniquet. Here is a list of those that are best suited for our purposes:

 Martens bandage (medical rubber bandage)
 Pezzer catheter
 Latex surgical rubber

Also, some people use basketball rubber, rubber from a gas mask or diving suit - all this also shows excellent results when shooting. My goal was not a super-powerful slingshot, so I used rubber, which is used by fishermen for donk fishing. There is another option to buy a harness for slingshots that is already on sale. We remember that everything does not last forever and sooner or later the tourniquet will break and it will need to be changed, so do not overload it too much.
