Do-it-yourselfers make tools and devices with their own hands

The self-taught Samodelkin’s device became a revelation for the craftsmen

The master is not distinguished by greed, which some masters suffer from, who do not want to share their finds with others and, like a dog in the manger, neither to themselves nor to people. And this self-taught inventor came up with a great device with which you will always be at your best and can even improve your standard of living. Why, you can put such a tool into production and sell it to everyone. Maybe this is too strong a word, but it’s worth thinking about automating and mechanizing all routine work at home.

8 tools for craftsmen.

You probably haven't seen many of them. Cool instruments are created by DIYers. These devices will help you work more comfortably in the workshop. The video was filmed on the “Hands from Shoulders” channel.

Making a Club

The most primitive weapon made of wood is a club or stick. What could be simpler, break off a branch and you're done. But if you suddenly decided to take this issue seriously, you wanted to make a strong, light, comfortable product, then you are faced with the question “how”. Making a weapon out of wood according to every rule is difficult. For the club, choose a young tree of suitable size. They cut down closer to the root, because at the butt the fibers begin to intertwine, making the material even stronger. Then, carefully, so as not to damage the top layers, remove the bark, cut off the knots, give the handle the desired shape, and if necessary, soak the workpiece in water or special brines for a day. Then the drying begins, a fire is lit and, in the smoke, protecting the coming club from the flames, they dry it. As soon as the tree has turned black, the blackness is removed with fine sand or hard grass. This is repeated six times, the surface becomes smooth and dry. Even if birch was chosen, the final product will be light and strong. Such wood does not rot. According to the same thesis, our ancestors made strong arrows and spears without steel tips.

Folding table for the master

1. Let's start with a folding table, which will be an excellent assistant in a small workshop. It will help save an already small area. The table has a compartment for all small things. A shelf on which you can lay out the necessary tools. Thanks to the large number of holes, a clamp can be used to quickly and conveniently fix the workpieces. Stops are inserted into them. It is convenient to fix the parts in a vertical position. If we insert it into the guide bolts, we get additional stops. Having a set of clamps and such a table, you can comfortably perform a variety of jobs.

Figure-of-eight antenna

The next option for creating a simple UHF television antenna is named after the shape of its design, “figure eight” or “zigzag”. Such a device will reliably pick up the signal even in a remote village.

In order to make an outdoor antenna for digital television with your own hands, you will need:

Amplifier (you can use any old one);
2 pieces of copper wire (180 cm each);
Plate (wood or metal) 15*15;
TV cable;
Iron mast for raising the antenna.

First of all, we create the body of the catcher: from copper wire we form two rhombuses with an optimal side size of 45 cm each. We attach the ends of the two elements to the plate: we form a ring from the core and slightly flatten it, screw it with bolts or solder it using a soldering machine.

We connect the amplifier and insert the cable plug into the connector. In general, that's all. All that remains is to install the finished structure on an elevated mast, which must be firmly dug into the ground.

To make an outdoor antenna for a TV, any conductive material of the appropriate cross-section is suitable: copper or aluminum tubes, strips or a profile element with a thickness of 1 to 5 mm. The main thing is to give the antenna body the correct shape.

Homemade folding stand

2. A very original idea for a folding stand for hand tools. Everyone is in their place. It doesn't take up much space. The design is based on furniture guides. The clamp holds the stand in the upper position. Neodymium magnets prevent instruments from falling out of their stocks. A great idea for DIYers who love to do everything with their own hands.

Coaxial cable antenna

To create this version of the antenna, you will need about 0.5 m of the most common television cable marked “RK-75”. One end of the insulated wire needs to be stripped to connect to the TV socket (put on the F-connector and an adapter for connecting to the TV), and on the second we will create a round antenna.

Step back 5 cm from the edge and remove the top layer of insulating impregnation compound. Then remove the winding from the central conductor of the cable and tightly twist the remaining wire strands into one bundle.

Next, step back 22 cm from the prepared edge of the cable and remove 2 cm of outer insulation along with shielded foil and braid, without affecting the insulation of the central core.

From this point, measure the next 22 cm and cut through the outer layer of insulation to the shielded foil. Now you need to connect the cable into a ring: to do this, we confidently screw the first prepared end to the newly created cut. That's all - you have in your hands a powerful antenna made of coaxial cable, made by yourself.

Connect it to the TV and start tuning channels. This antenna is considered a good option for receiving digital television. It is better to install the antenna outside the window and on the side of the TV tower, since the walls of the building can drown out the desired signal. You can experiment with its position yourself.

Homemade apple press

4. If the harvest is large, then the question arises, where to put it? A great option is apple juice. For store-bought juicers, apples need to be cut and peeled, which is inconvenient. The grater shown below can handle whole apples. All that remains for Dali is to squeeze out the resulting mass under pressure. As a result, we get natural, tasty juice and almost dry cake.

Second part

Tires are a popular garden material

You can even make various useful things for your garden with your own hands from old car tires.

From car tires you can make not only classic fences for enclosing an area, but also a lot of other things. For example, garden paths between the beds.

They are good because weeds will never grow under them. It’s also convenient to walk on such rubber paths between the beds after heavy rain - you don’t have to get stuck in the mud.

You can also make large flower beds from car tires that will serve you faithfully for many years.

Therefore, we take all these ideas into account and design our summer cottage. It will be both beautiful and convenient. Car tires are cheap material, and getting it is not a problem.

Cheap homemade grinder

8. The most budget version of the grinder, created by the Samodelkins. Plastic bottles are used as rollers. They are mounted on bearings. The belt on the rollers is adjusted using thumbwheels. The tension is adjusted with a bolt. The structure is driven by a drill. You can slightly improve Samodelkin’s design by replacing plastic bottles with polypropylene tubes.

Shower at the dacha

A cottage and garden are not only a place to relax. To make your surroundings beautiful and cozy, you need to constantly work on this: take care of the plants, maintain order in the area, etc. And after work, of course, you need to wash off the sweat, dirt and fatigue.

Therefore, a summer shower for any summer resident is one of the mandatory attributes that helps improve comfortable conditions. There are many different options: a classic shower in the form of a closed booth, for example.

However, it is not always possible to allocate a permanent place for a shower stall on the site. Therefore, in such situations, you can use mobile structures.

You can, for example, make a portable summer shower with your own hands from plastic (polypropylene) pipes. This design is good because you can use it as needed and store it in a shed.

You can also make an outdoor shower from an old wooden pallet. Its peculiarity lies in the fact that the stream of water does not pour from above, but comes out from below. A little unusual, but overall quite convenient.

The self-taught self-made man rocked the network with his video

The self-taught inventor captivated the online community of craftsmen with his video, in which he presented a fundamentally new utility model for improving the efficiency of work for craftsmen and those who like to work in the garage. The best part is that it doesn't require you to buy an idea. And what’s more, you can do all this yourself and even a novice master can handle it. All this is to the benefit of every resident of the cities in which the masters have settled, because with such a high level of skill, now you won’t want to hammer the walls at home on weekends or rattle with some kind of ultra-decibel grinding machine of unknown purpose. With such a device, you can safely create your own separate workshop and live the rich life of a Russian craftsman.

A simple antenna for receiving digital TV

Another useful type of home antenna for the dacha is the “butterfly”. This is a very simple design, to create which you will need:

Board or plywood about 60 cm long and 7 cm wide, thickness about 20 mm;
Shielded copper wire with a 4 mm core cross-section;
Coaxial cable “RK-75”;
Washers, screws, soldering iron.

Below we provide a marking diagram according to which you need to make the base of the butterfly antenna.

Scheme

After this, prepare 8 pieces of copper wire, each 37.5 cm long. Step back 17.75 cm and remove 2 cm of the insulating layer in the center of each piece. Give them a V-shape so that the ends of the elements are at a distance of 7.5 cm from each other (this shape is considered optimal for high-quality and clear TV signal reception).

The next step is to prepare two more wire elements about 22 cm long. Mark each element into 3 equal parts and strip the wire insulation between the resulting sections.

We will need two more small pieces of wire to connect the antenna to the socket.

Now all that remains is to simply assemble all the prepared elements into a single structure and solder the cable to the plug.

This is how you can easily make your own effective butterfly antenna for receiving digital television.

Homemade tool rocks the internet

This video shook up the community of invention lovers on the world wide web. The master thought about this idea for years and finally brought to the public discussion an idea that was ingenious in its simplicity and radically profitable for those who used to chisel walls with a hammer drill, realize their inclinations as a woodpecker and a brilliant builder-grinder, and now can make themselves rich for free, working in silence a workshop in a garage or even in a separate building.

And at the same time, you don’t have to spend money and take money saved for beer out of your stash. All this is free - the master loves to show the whole world the useful things he comes up with.

sprays

This product is not just for beauty because you can use its flammable materials to start a fire. What you need to do is use a lighter to light the fire before spraying fire with hair spray on the aggressor's face, making it a perfect flamethrower that can save your life.

You can easily store this homemade weapon in your pocket or bag and take it out when you encounter danger and want to deactivate and/or blind an attacker. But make sure that the container does not get too close to the fire, as it may also explode and harm you.

Uprooting of seedlings and weeds from a square for homemade people

Good afternoon My long absence from the channel was not in vain; during this time I managed to do a lot of household chores. And of course, I stocked up on a bunch of homemade products that I will show you, my dear subscribers and guests! There is no point in posting everything at once, because this also takes a lot of time, but if possible I will try to post at least one per day. Not only am I sitting at the computer, I can’t leave my workshop. Messing around in the garden is another hobby of mine; I spent a lot of time there in the summer. Caring for plants and weeding, although a pleasant activity, however, also requires a lot of effort. And how I would like to make a lot easier. Wanting alone is not enough, so you need to make useful things yourself that will make your work easier and make it a pleasure, rather than hard labor with a farmhand.

Today I’ll show you a device that I successfully used almost all spring and summer and will, God willing, last for more than one season. Do-it-yourself uprooter To make it, I took a square with walls 40 by 40 mm, 220 mm long. I didn’t cut this length on purpose; I had a lot of such scraps left over from other construction work.

I drew two oblique lines along the walls to the corner of the square. Having cut it out, it turned out to be such a spear. A pipe with a diameter of 25 mm was welded into the inner part of the angle. From the outside I welded a square right in the middle of the square. Instead of a square, you can weld a square, but it seemed to me that it would be more convenient.

A metal handle was installed in the pipe so that it would not break under load, because the force falls mainly on the handle. When working with a flat cutter, some types of weeds still germinate after a certain time, especially after rains. And having ripped it out by the roots, I eliminated this possibility and my garden became well-groomed and beautiful. Without damaging the root system, they can also remove seedlings for replanting, which is what I did at the beginning of the season with strawberries and other plants.

A simple cheap homemade device for picking berries

We recommend this device for DIYers.

Gooseberries are a tasty and healthy berry. The plant itself is quite unpretentious and does not require any special care. The berries grow large and are quite convenient to pick. And everything would be fine if not for the prickly gooseberry branches. Because of these garden “cacti,” my hands used to constantly have small scratches. And several times you will think “do you need it - there are so many berries” before you climb deep into the bush for the harvest. But a few years ago my husband made my life easier. He spotted one very simple but useful device for picking berries on the Internet. What is it used for and how is it useful?

In fact, such a picker can be used not only for collecting gooseberries. I also use it to collect any other berries/fruits in hard-to-reach places that I can’t easily reach with my hand. For example, to remove plums, cherries or apples from high branches. How to make a device for picking gooseberries? Everything ingenious is simple! Take a plastic bottle and cut a droplet-shaped hole on the side. Depending on what berries/fruits your picker is intended for, this is the diameter of the drop. For gooseberries, 5-7 cm is enough, for apples and plums more, so that you don’t have to aim for a long time and try to hit the fruit. The volume of the bottle will also depend on what you are collecting. For berries, a 0.5 liter bottle is better.

The droplet's nose should be directed towards the bottom of the bottle. You can also make a cut a couple of centimeters in continuation of the spout so that the branch can be better grasped. That's it, our device is ready! We will pick berries by holding it by the neck.

It really is much easier to do this with him. Not only do your hands remain scratch-free, but the work also goes faster. After all, the harvested crop will be poured into the top of the bottle. Accordingly, there is no need to “climb out” of the bush after each berry, put the harvest in a can or jar and climb again. Plus, we can get berries even from the most inaccessible places. And the most important thing is that such a device is made in 3 minutes, does not cost a penny, and makes life much easier. If it gets lost or dirty, no problem - we’ll do another one without any problems! So, gardeners, take action!

For construction on your own

The topic of construction or renovation probably worries everyone. And, naturally, everyone who is involved in it wants to finish it quickly with minimal financial costs. Therefore, if you want to save money, you can make some construction materials yourself. For example, these could be wall SIP panels or such a useful tool as a vibrating plate, the need for which often arises for many owners of a personal plot.

Homemade SIP panels

To make them, you need to prepare a flat, hard platform. Place a sheet of OSB 10-12 mm thick on it using a rubber spatula with teeth, apply glue to it.

Then lay sheets of grade 25-30 foam plastic on the glue. After this, an adhesive mass is applied on top of the laid foam, as well as on the bottom OSB board, and a second sheet of OSB is laid on top.

If several stacked slabs are being made at the same time, work should be done quickly until the glue hardens. Typically, no more than 4-5 panels can be prepared in this way at a time.

After preparing the formed slabs, you need to create pressure using a press. Since at home, of course, there is no hydraulic press, it can be replaced with a thick plywood sheet laid on prepared SIP boards over the entire plane and loaded for 2-3 hours, for example, with several bags of cement, sand or other cargo. You can even use a passenger car by driving onto a plywood sheet along a pre-made overpass.

After the glue has completely dried, the homemade panels are ready; they can be placed in a separate stack and you can begin preparing new panels. The manufactured panels should lie unloaded for another day, after which they can be used for their intended purpose.

Making a vibrating plate

To make a homemade vibrating plate, you will need to prepare:

An electric motor with an IV-98E eccentric, which is the main part of the vibrating plate.
Steel sheet, at least 8 mm thick, size 450x800 mm. It can be ordered at any metal warehouse.
Two pieces of channel no more than 400 mm long.
An inch pipe for the handle and two rubber bushings for attaching it.
The tools you will need are a welding machine, a grinder and a set of wrenches.

On the narrow sides of the slab, stepping back 80-100 mm from the edges, make an incision with a grinder to a depth of about 5 mm. After this, bend the edges towards the cut at an angle of approximately 250 and weld them. The bends are needed so that the vibrating plate does not sink into the material it compacts and moves freely along its surface.

Then, across the slab at a certain distance calculated for mounting the electric motor, two channels are welded with the shelves down. Through pre-drilled holes in the channel, using M10 bolts, an electric vibrator is attached to them.

The handle, made of pipe, is attached to the vibrator through soft rubber bushings, which can be purchased at an auto parts store or hardware store in the hardware department.

Thus, you can make a lot of useful household things with your own hands, spending only a fraction of the money that you would have to pay when buying a finished product. You just need to put in some effort and have certain skills.

Landscape design

To implement various ideas for a do-it-yourself garden on your site, you do not always need to invest a lot of time and effort. We tried to collect for you as many simple landscape design projects as possible.

For a more comfortable pastime at your summer cottage with family or friends, you can create special recreation areas.

These can be either round or rectangular concrete platforms, or terraces made of ordinary or composite boards.

Recreation areas with a dedicated fire pit are especially popular today. It’s great to gather at such venues in the evenings. You look in fascination at the flames flying out of the fire, breathe in the fresh air - beauty!

It would also be nice to have a pond at the dacha. Throw some fish in there or make a fountain, and admire the man-made world in moments of rest and relaxation.

Moreover, it will take no more than one day to make the simplest artificial reservoir. Here's a real example.

Agree, this is a small “price” for the feeling of boundless peace that admiring the end result of your work will give.
