How to make dumbbells from cement. How to make a dumbbell at home? Practical advice

Not everyone who wants to go in for sports has enough time to visit the gym, and home workouts require certain equipment, the cost of which is quite high. The most popular are dumbbells. They are involved in almost all exercises. And if you do not plan to purchase sports equipment in the near future, you should not abandon classes. You can do dumbbells with your own hands from fairly cheap materials. To do this, just read the instructions on how and from what they are made.

Dumbbells from plastic bottles with their own hands

Ordinary plastic bottles make it possible to make dumbbells in a short period of time with minimal monetary expenses, which can be used immediately. The main thing is to fix the structural elements so that it does not collapse during training.

To assemble one plastic shell, you will need: 2 bottles, adhesive tape or insulating tape, filler.

Step-by-step instructions for making dumbbells from plastic bottles:

Cut out the middle part of the bottle. Fasten the separated elements (upper and lower) with adhesive insulating tape.
In the tank fall asleep filler. If the projectile makes a small weight, use cement with sand. Dumbbells with a greater mass require the addition of metallic inclusions, which can be balls from bearings, nails, various metals. The choice depends entirely on the availability of a material.
When the neck of the bottle is filled, a pipe or stick made of metal or wood is inserted. Roll up the joints with tape or tape. Thanks to this manipulation, you get a non-slip, soft and quite comfortable handle.

Before starting classes, you should carefully check all the connections so that the filler does not “leak out”.

Ordinary plastic bottles are not only suitable for collecting dumbbells, but also barbells. This projectile weighs much more, therefore, the amount of source material increases.

To assemble the rod will require: at least 8 plastic bottles, neck, material for the filler, electrical tape or adhesive tape.

Instructions for the manufacture of plastic rods:

Bottles are filled in the same way as dumbbells.
Choose a material for the neck. It is better to take fittings or a pipe that lie comfortably in your hand.
At each end of the neck, ready-made loads of filled plastic bottles are placed and wrapped with adhesive tape. On each side is four loads.
Check the quality of attachment. The neck should not move out or form a backlash. If the connection is poorly made, tape is still wound.
To increase the weight of the bar allows laying of additional weighting materials in the form of bars between the loads from the bottles and so on.
Each additional load must be wrapped with a new layer of tape. You can increase the load up to 100 kg.

To navigate the choice of material is quite difficult. The approximate weight of the dumbbell or barbell can be calculated based on the data presented:

Weight of a two-liter plastic bottle with various fillings:

water - 1,997;
compacted sand - 3,360;
wet sand - 3,840;
crushed stone (cavern) - 2,600;
lead - 22,800.

Weight is given in kilograms.

We collect shells from concrete

Cement base allows you to get heavier dumbbells and barbells, rather than using plastic bottles. Pancakes are not only more impressive weight, but also look much more solid. They are molded from the cement mortar in a special form, inside which is the neck. The disadvantage of this design is that the load of the projectile cannot be adjusted or adjusted for someone else.

To start working with another weight, you need to make a new barbell or dumbbells. Weighting, in fact, are individual, and still quite fragile and "loose". The last drawback is eliminated by the introduction of glue into the PVA solution. And if classes are not held on the principle of powerlifting, when the projectile is thrown on the floor, then it will serve for a long time.

The manufacture of concrete dumbbells (rods) will require: a metal pipe with the required length, bolts or screws, cement mortar, PVA, as well as a mold for casting cargo.

Step-by-step instructions for making cement shells:

At the ends of the pipe with a drill make holes in four directions. Screws are screwed into the holes, so that they are fixed as securely as possible at the ends and form a kind of cross. They become a skeleton holding cement.
Form for pancakes made from a flat bucket of mayonnaise or paint. You can use another container. The main thing is that the weight should be chosen in such a way that is necessary for training and is suitable for the body of the student. Glue is added to the solution for hardness or oil paint is introduced.
A pipe is placed in the filled mixture and it is waited for about four days until it is completely grasped. Repeat the manipulations described in the previous paragraphs for the second side. Make a support. The design is tied up or suspended for another four days.
When the cement is fully grasped, over the next week, the projectile is soaked at least twice in water so that it gains even greater strength.

Shells, filled in a two-liter form, can weigh about 5 kg. The exact weight is due to the composition of the involved mixture.

In order to perform the "farmer's walk", it is not necessary to make projectiles. It is enough to take two ordinary cans and hang on a stick. You can use tires filled with sand or any other filler. Other exercises with a similar design are difficult to perform. They require the use of full-fledged dumbbells.

When sports are becoming regular, there is a need to purchase more professional projectiles or make such metal. They are practically no different from the factory. The difference is that hand-made dumbbells will be much cheaper. It is possible to make simultaneously a neck and pancakes from one pipe. It is best to make dumbbells from metal.

To make projectiles, it is necessary to prepare in advance: a thin-walled tube having a diameter slightly larger than the neck, for which it is better to take a metal rod, lock locks and sheet steel. Work on the manufacture of dumbbells should be carried out in the metal workshop.

Step-by-step instruction:

From metal scrap with a diameter of about 3 cm saw off about 35-40 cm neck. To keep the projectile in hand, about 15 cm are cut from the thin-walled tube. The resulting piece is put on the neck. Further, if desired, it can be covered with a relief or wrapped with electrical tape.
Pancakes cut out by autogen from sheet steel. The weight of a single disc with a diameter of 18 cm and a thickness of 1 cm is 2 kg. This makes it easy to calculate the required number of pancakes to get a mass of 10, 20, 30, 40 kg. The size of the discs also makes it quite easy to change the weight of weighting agents from small to maximum. Cutting a whole set of pancakes allows you to constantly work with different weights.
The next step is to make locking locks. The diameter of the pipe take more than the neck. Rings are cut from the product with a width of 3 cm. They should move freely around the fingerboard, but not slide off. One hole is drilled in the rings with a diameter of at least 1-1.20 cm. They are necessary for screwing in the screws, which allows the rings to hold pancakes and press against the fingerboard. The main thing is to take care of the quality screw pressure so that there is no backlash.
At the last stage, they start assembling dumbbells. On the neck with a pipe cut in the middle, they hang pancakes and fix them with locking locks.

The dumbbells made by the described method are not inferior in quality to the factory ones; they allow working with both low and high weight.

General tips and advice for assembling dumbbells at home

The best, without any doubt, are metal shells, but they are much more difficult to manufacture than other designs. It is necessary not just to make the discs, but to correctly choose the width of the pancakes, qualitatively perform the locking according to the calculations. It is recommended not to increase the width, but the diameter of the disks. You can make some heavy and some small pancakes.

To dumbbells look presentable, the details are polished and painted. This will only slightly make the process of creation and increase the cost of projectiles, but they will look no worse than the factory ones, and they will have a much lower price. Classes with such equipment will bring more pleasure, and, consequently, the motivation and effect of training will increase.

For many who want to play sports, the question of visiting the gym is closed due to lack of time, and owning sports equipment for working at home is not so cheap. Despite the ease of manufacture, the sporting goods industry is simply not interested in selling pieces of metal cheap.

Before you make them at home, let us see what they are and what their varieties are. All dumbbells are divided into cast and collapsible. The first have a constant mass, it can only be changed by destroying the dumbbell. Most often, they are used in sports halls, as there must always be access to the inventory of the desired weight and no one wants to spend time assembling and disassembling it.

The second consists of a neck and pancakes or other types of goods. Often they can be found in the home halls, since such an option is cheaper - to buy two dumbbells weighing 20 kg with the possibility of reducing weight is much cheaper than individually buying 2, 4, 6 ... 20 kg.

Also dumbbells are made of different materials - concrete, cast iron, steel coated in the form of rubber, etc. The material and coating create usability and affect the durability of the product.

There are also differences in the form of pancakes, which are hung on the neck. It can be round, hexagon and other versions. There is a self-regulating weight. Every day there are all new options that can be called high-tech, but the price of such equipment is not commensurate with their benefits - it makes no sense to overpay.

Create an inventory of plastic

Dumbbells can be collected quickly and very cheaply through the use of plastic bottles. Because of the simplicity of the design to engage with such shells can be immediately after production. On one dumbbell we need: 2 plastic bottles; filler; insulating tape / tape.

Manufacturing

The middle of the bottles need to be cut, and then re-fasten the top and bottom of the adhesive tape.
Then you need to score the capacity of the filler. In the role of the filler, sand and cement are perfect, but if you need more weight, then do not hesitate to add nails, scrap metal, balls from bearings, in general, let your fantasy roam.
After filling it is necessary to insert a wooden or metal shelf, or a pipe into both necks. Cover the places with tape or tape. The result is a very comfortable, soft and non-slip handle.

We collect the barbell

Plastic can be assembled and the bar. Since it in itself implies a lot of weight, you need a lot more bottles. For the rod will need:plastic bottles, at least 8 pieces; filler; neck; adhesive tape / duct tape.

Manufacturing

We use a pipe and fittings convenient for a hand as a neck.
Fill the bottle the same way as in the dumbbells.
The finished cargo is wrapped around both ends of the neck and wrapped with adhesive tape. We get four bottles on each side, between which passes the neck. Securely fasten the load to the neck so that it does not move and form a backlash.
For a more impressive weight, we take another load and lay it in the intervals between the available bottles, like logs. Each new layer is recommended to be wrapped with new scotch tape - this way you can increase the weight of the rod and up to 100 kg.

To make it easier for you to determine the size, number of bottles and their filling, we give the following information:

Making concrete shells

Cement-based dumbbells are much heavier than bottle dumbbells. Large and heavy, solid pancakes for dumbbells and barbells are obtained from the solution, solidified in a certain form with a fingerboard inside. The main drawback of such equipment is the inability to optimize for a constant increase in loads or for another person.

That is, if you need a dumbbell with a different weight - you will have to make a new one. Also the lack of cement is often called its fragility and friability. To strengthen the mixture, glue (PVA) is added to the solution, and if you do not like, like a powerlifter, throw a barbell on the floor with a triumphant cry, then it is unlikely that it will quickly become unusable.

So, we will need:metal pipes of suitable length; drill, screws or bolts; cement mortar, PVA glue; form for cargo.

Manufacturing

To get started, take the pipe and drill at its ends in four directions to drill holes for the screws. Screw the screws so that they hold onto the tips as tightly as possible and stick in the shape of a cross. It is necessary to hold the cement.
Next, take the form (flat bucket of paint, mayonnaise, or whatever. It is important that the size only fits your weight), and knead the solution with glue or oil paint for hardness.
Insert the tube into the solution and wait four days until it is completely dry.
Then you need to do the same on the other side. Support, tie up or hang up for another four days.
After complete drying, you need to soak the dumbbell in water a couple of times for a week to make the cement stronger.

Help: if you prepare concrete in 2 liter form, the weight of the projectile can reach 5 tog (depends on the composition of the mixture).

Of course, for such an exercise as a "farmer's walk", two cans, hung on a stick, will also fit, and you can also weight the metal neck with car wheels, tires with sand and much more. But only such cement dumbbells will allow to fully exercise sports.

On the other hand, they are useful only in the first stages. If your passion for sports goes further, then you will understand that it is time to do dumbbells from metal.

Dumbbells made of metal

Metal pancakes and vultures are analogues of the factory, but only cost you less. If you make a barbell for dumbbells and barbells from one tube, you can use the same pancakes, which will save you time, money and space in the room.

In order to make these dumbbells, you will need: a metal workshop; metal rod - the future neck; thin-walled tube with a diameter slightly larger than the neck; Sheet steel; locking locks.

Manufacturing

First we make the neck. In the role of the base is great scrap about 3 cm in diameter. We cut off the neck of 35-40 cm in length from it. Then we take a thin-walled pipe and cut off 15 cm from it. It should be put on the neck to protect the place for the hand, in other words - it will be a pen. After the dumbbell itself has been manufactured, it can be wound with tape or covered with a relief.
Cutting discs (future pancakes) from sheet steel by autogen. Do not doubt their weight - with a sheet thickness of 1 cm disc with a diameter of 18 cm will weigh 2 kilograms. Hang on your dumbbell 10 cm on each side - and you will be 40 kg! If desired, vary the size of the discs to arbitrarily change the weight from the lightest to the heaviest, when training different muscle groups. It would be nice to cut the whole set according to the prototype of factory dumbbells so that in total the weight of one dumbbell could reach 25-30 kg - you will hardly need more.
We manufacture locking locks. We find a pipe with a diameter slightly larger than our neck, and we cut off 3 cm wide rings from it. It is necessary that they freely go around the neck, but do not slide off by themselves. In each ring, you need to drill a fairly wide hole (about 1-1.2 cm) for screws. After screwing in the screw, the ring will be pressed against the fingerboard and hold the pancakes. Just do not forget to press it close to the disks so that there is no backlash.
We start assembling dumbbells: in the middle there should already be a tube from point 1, then we hang the discs and fix them with locking locks.

Tips for making and using homemade shells

The best, of course, are metal dumbbells and barbells. But in their manufacture you need to be as attentive as possible so that the width of the discs and the quality of the locks match your calculations. Too wide discs are better not to use - it is better to increase their diameter, or make 2-4 very heavy discs, and the rest - smaller.

Do not be lazy to clean and polish every detail of your new dumbbell or barbell so that it looks presentable - paint the pancakes, as manufacturers of sporting goods do. In the end, it will cost you all the same cheaper than purchased projectiles, and the pleasure of practicing with such equipment and the effort expended on it will motivate you to regular training, which will certainly benefit you.

The network caught photos of craftsmen, hanging on their dumbbells about 100 kg, showing the quality of workmanship. Do not even think about wasting energy on such tricks, it is better to make a barbell, and hang 200-300 kg on it for deadlift - this is impressive.

Depending on the possibilities, you can buy handles and griffins in the store, and make pancakes yourself or order them in the workshop. Then the qualitative form and convenience of a branded handle will help to hold the grip better, and the rest will be much cheaper.

Record sizes and weights

In modern gyms there are long rows of dumbbells of various weights. Most often, their maximum weight is up to 50 kg. But in the world there are iron monsters that exceed this figure. For example, in Youtube there is a popular video, where in the Rich Piana hall with their colleagues they are trying to lift a dumbbell with a weight in 170 kg!!!

And in the gym, where Ronnie Coleman was engaged, there are his nominal dumbbells, each of which weighs 113 kg. Yes, 8-fold Mr. Olympia used them in his workouts. Anyone who can raise them will receive a free annual subscription to visit this gym. Unfortunately, the Internet could not find information on whether there are such lucky ones.

If you made dumbbells yourself or know more ways how to make them - write in the comments, it will be interesting for other readers!

You will need

- eraser bottles (from under the "Fanta")
- tin cans (from condensed milk)
- two small pieces of metal pipe
- cement mortar, sand or water

Instruction

There are several ways to do it. First we look at the one that is easiest to implement. To do this, you will need empty plastic bottles (Fanta bottles are ideal, as they will be comfortable to hold in your hand), water or sand, and electronic scales if you want to adjust the weight of the dumbbell.
Getting Started:
1. Take the bottles, carefully wash them, get rid of the labels.

2. Fill the bottles with sand (you can also with water, but you will have to change the contents often).

With the following method, you can make dumbbells that will weigh much more than dumbbells from bottles. Prepare the following materials: a pair of tin cans (from condensed milk, or similar), if you have large dumbbells, you can take paint cans that are of different sizes, a piece of metal pipe (about 20 cm), cement mortar.
We make dumbbells:
1. Take two jars, rinse and dry them.

2. Take one jar, fill it with cement mortar.

3. Insert one end of the metal pipe into the solution.

4. Hold for a couple of minutes until the solution begins to thicken and the pipe will hold itself upright.

5. Leave the future dumbbell until the cement is completely cured.

6. Fill the second jar with the solution.

7. Insert the free end of the pipe into it, which is poured into the first can.

8. Hold for a while.

9. Secure the pipe in the desired position and leave it to solidify.
It will take you more to make using the latter method, but they will be very strong and comfortable.

What to make the neck

First of all, you need to decide what the bar is made of. This should definitely be a very durable material. Either a piece of wood will serve as a neck. In addition, the diameter of the neck should not be less than 4 cm, otherwise the grip will be painful.

With a wooden object is much easier to determine, and it will not add as much additional weight to the projectile, as iron. The most ideal option would be an old mop from your pantry or a rake from a shed. If their cutting seems too long for you, do not worry - this space will come in handy in the future. You will string improvised “pancakes” on it. It remains to separate the cutting in any suitable way.

It is not easy to pick up an iron brother for a homemade bar, but you can for some reason want just such a bar. For example, if you plan to work with a weight of more than 50 kg. Then go to the construction market and purchase an all-metal rod there. Its length should be about 2 m, and the diameter of the cross section - about 35 mm. You can also take a pipe with a diameter of about 4 cm, but it is poorly suited for large weights.

What to make "pancakes"

The easiest option than to load our neck is plastic bottles. They need to be filled with something heavy. Sand, small stones, cement, even plain water will do. You can take 1.5 liter bottles, you can 2 liter. It all depends on your claim, how much weight you need. The weight of one such bottle can reach 4 kg. Just put them around the ends of the neck and tightly wrapped with tape.

Another option is to make cement pancakes. This will have to tinker a bit, and the weight of such burdens can be predicted very approximately. Find a suitable shape, such as a large can of paint. Fill there with cement, place the neck of your future rod and wait for complete hardening. Full freezing will occur at least in a day, and it is better to wait for four. Only then can we proceed to making the second “pancake”. When it dries, firmly support the entire structure.

If there was no cement at hand, use all your imagination. Look at the warehouse and in. Use old car tires, car engine parts, cans filled with scrap iron. Anything, just remember that this is not the most convenient option. It is best to turn to the cement one - it is such a home-made bar that will allow you to fully engage in sports!

How to make dumbbells with your own hands, drawings, calculations, description of the design.

The sports equipment offered for consideration consists of the following parts:

Handle (neck)
Castle
pancakes

Details are made of metal by turning. In the manufacture of parts, it is necessary to strictly observe the dimensions of the drawing and the metal grade of appropriate density. When these conditions are met - each size will correspond to its weight.

A PEN

We produce stainless steel (density - 0.00786 (g / mm³)). The handle has stops on both sides for fixing pancakes. To the stops cut square thread. The square thread profile is not subject to standardization. This type of thread is used in mechanisms where spontaneous unscrewing should not occur under the influence of applied loads.

CASTLE

We produce stainless steel (density - 0.00786 (g / mm³)). The inner square thread is cut in the lock.

Pancakes

Let's make of plastic ductile iron (density - 0.0071 (g / mm³)) of four versions. Each size corresponds to its weight. Metal pancakes, after turning, must be coated with a protective coating, preferably electroplated. This will give the product anti-corrosion resistance and a good presentation.

First performance

Second performance

Third performance

Fourth performance

The thickness and mounting diameters of all parts are the same; only the outer diameter and the diameter of the metal sample are changed.
Making dumbbells with your own hands according to the drawings is easy if you yourself are a turner or have such friends.

Consider the table of distribution of weights of used parts (kg):

Handle - 2.0
lock - 0.5 + 0.5 = 1.0
pancake (first performance) - 1.0 + 1.0 = 2.0
pancake (second performance) - 1.5 + 1.5 = 3.0
pancake (third performance) - 2.0 + 2.0 = 4.0
pancake (fourth performance) - 2.5 + 2.5 = 5.0

With this distribution, you can collect various weight combinations.
We already know how to make dumbbells with our own hands; now we’ll stop at weight combinations.

In this issue we will tell you how to make a barbell, dumbbells and pancakes at home with your own hands.

To begin with, let's say that homemade simulators are very similar to factory serial models. First we need a bar (or analog bar). Make barbell start with the neck. It all depends on how much weight you are going to lift, on different requirements for the neck. I think you have already guessed that the more you are going to lift the weight, the greater the strength should be at the neck, but the strength should be good even if you lift the 50 kg bar, i.e. relatively large weights.

Barbell bar can be performed:

From a multifaceted section or all-metal rod. Most often, such rods are sold in construction markets or in metal shops. The diameter of the rod should be about 25-35 mm, and a length of about 2 meters. At each segment of 30 cm from each end, you can fasten a washer or a piece of pipe 15-20 mm long, the inner diameter should be slightly larger than that of the rod. The washer or pipe must be attached by welding or rivet to the rod. This is all necessary in order to fix the burden in the future.

You can also make from the pipe with a diameter of 30-40 mm, and the wall thickness should be at least 5 mm. This bar is not suitable for heavy weights. On each side of the pipe, you can drive a round rod of the desired diameter tightly inside, and then fasten it with rivets, after which you can hang the discs.

The neck can even be made from wooden materials , but of course it will be too thick and not strong enough (although it is suitable for small scales). To make the neck of a tree you need to take hard wood, for example, you can take birch. The diameter of such a neck should be about 40mm. Such a bar will withstand no more than 50 kg.

Home-made pancakes for our bar

Of course, it is best to order pancakes at the factory. Although it is expensive for the money. But you can also make them yourself from steel or concrete. It is even easier than with the neck: first you need to calculate the size and diameter of the bore. It is also necessary to make the edging of the desired size of wood or plywood. After making the edging, you need to pour the solution itself inside (we make a solution of cement and sand), but do not forget to reinforce the disk with a wire mesh cut out in the shape of a circle. One such pancake should dry for about three days. After drying, it is advisable to pour water on it, and even let it dry for a few days, so it becomes even stronger. Concrete pancakes are much smaller than steel (or cast iron).

And in total we can get a good sports equipment, and no worse than the factory.
