Do-it-yourself pipe bender for a profile pipe: basic data
Before studying the working documentation and installation operation algorithms, you should accurately determine the intended purpose of the product. A pipe bender for a profile pipe with your own hands must be designed for certain forces, workpiece sizes, and materials. It is easier to establish meaningful criteria after familiarizing yourself with the parameters of devices tested in practice.
What are these devices for?
To create the necessary force, a lever mechanism is installed here. A metal pin is used to fix the free section of the pipe. It is installed in suitable grooves of the “comb” before performing work operations.
Using this factory sample as an example, it is easier to study the design features:
- Handle (1) adjusts automatic stroke piston in the opposite direction. This solution reduces the burden on the user.
- Installed inside the case hydraulic system. When the handle is moved up and down, a force of up to 150 kN is transmitted to the working piston (8). This is quite enough for quickly bending workpieces made of durable metals.
- Support rollers (3, 4) are installed in the required frame holes open type(5, 9). They do not damage the surface, but provide reliable fixation.
- This removable segment (6) is designed to be bent at an angle of 90°. But with the appropriate configuration, it can be installed on a similar product of a different shape.
- The robust housing (10) is mounted on three supports (7). Rubber pads prevent movement during work operations.
- In addition to cleaning from dirt, you should occasionally check the condition of the oil filter (11). No other regulatory procedures are needed.
This technique uses a workpiece the desired shape. The pipe is pressed against it using a rotating roller and lever.
Important! Before bending the workpiece using certain radius You should study specialized reference books. They provide data on the permissible deformations of pipes made of different materials, with different wall thicknesses. If these instructions are violated, visible or hidden defects will form in the finished products.
Relatively small mechanical loads on working tools are created by levers and manual force. To work with durable metals The equipment is equipped with hydraulics.
Making a pipe bender with your own hands for a profile pipe: drawings and other preparatory operations
A simple device for bending aluminum and plastic blanks is shown in this figure.
To make such a structure you need a strong one. After marking, a round profile is cut out of it. The remainder is used for making support element. The created parts are rigidly attached to the supporting surface. To ensure the strength of the connections, in addition to screws, clamps are used. Next, the pipe is bent by hand until the desired shape is formed.
Before creating this simple pipe bender for a profile pipe with your own hands, it is recommended to make a basic drawing with dimensions. A template made of thick paper or cardboard on which the markings will be applied will come in handy. It is clear that for the manufacture of more complex structures it is necessary to prepare complete design documentation.
It is not necessary to strictly adhere to engineering standards in order to make a pipe bender for a profile pipe with your own hands; a schematic image is quite enough. You just need to indicate all the dimensions, decide on the materials, technological process And components. The project will help solve several practical problems:
- During the preparation process, it will become clear whether it is necessary to use other special equipment.
- A complete list of necessary components will be needed for targeted visits to certain stores.
- We must not forget that the machine must be protected from adverse external influences using wood impregnation.
- Some parts will be too difficult to make yourself. Appropriate orders should be placed in specialized workshops.
Important! When bending strong metal pipes it takes a lot of effort. In order not to take unnecessary risks, you can use drawings of a proven design, or copies of an industrial design.
Making a manual homemade pipe bender for a profile pipe with your own hands: video and detailed instructions
Here we talk about how to quickly create a pipe bender with your own hands for a profile pipe (video).
The master used available materials, a channel, and part of the drive from an old bicycle. But he had to create the connections himself to ensure the integrity of the heavy structure.
To find out how to make a pipe bender for a profile pipe with your own hands, the drawings and videos are supplemented with descriptions of work operations. Below are the algorithms for several assembly technologies.
Rolling pipe bender
| Drawing | Actions |
 | To create a high-quality one, you can use this drawing as a sample. Here the workpiece is placed between three rollers. The extreme ones (2) – perform supporting functions. To install them at different distances (to obtain required angles bending) grooves are made in the support strips (1). The necessary pressure is created using a screw mechanism (6, 7). The force is transmitted through the central roller (4), which is rotated by the handle (5). |
 | The holes in the lower parts are created according to these dimensions. A channel with a wall thickness of 4 mm was selected for the workpiece. |
 | The upper part is created with cutouts. They must be made level so as not to interfere with the movement of the support screws. |
 | The thread is cut in accordance with this pattern. |
 | For the handle, you can choose a finished product, or use these sizes. |
 | Once assembled, you will get such a cute and functional product. There are no welded joints. But the components are difficult to make on your own without professional skills and specialized machines. |
Hydraulic pipe bender
The screw mechanism performs its functions too slowly.
This design uses a standard jack. It is fixed rigidly to a bar, which is suspended on two springs. This solution simplifies manipulations with a heavy jack when installing workpieces and clamping segments.
The pipe rests on two round pins. They can be rearranged into other holes to create products with the desired radius of curvature. Parts of a durable steel frame (4-5 mm) are bolted and welded. The design turned out to be collapsible. If necessary, it is not difficult to dismantle it. The jack can be used for other operations.
Holes are created at the base of the frame. Through them the machine can be firmly attached to wooden floor nails, screws. This gives additional stability to the stationary structure. Its metal parts are degreased, coated and painted. Besides the good appearance provided good protection from destructive processes.
For your information! When creating a homemade pipe bender for round pipe rollers, stencils and segments with a different shape of contact surfaces are used. The technologies used are the same as for bending profile products. The above drawings with appropriate modifications will be useful.

The need for reliable and simple device for bending profile pipes occurs when House master begins to seriously study metal. Gazebo frame, carport, garden bench, Workbench…
These and many other structures turn out strong and beautiful if the profile metal for them is carefully bent on a special profile bender.
There is always an economical alternative to buying a ready-made machine, since you can make a pipe bender for a profile pipe with your own hands in a home workshop. Before the first workpiece is clamped in a vise, we suggest that you become familiar with the operating principle and existing varieties homemade pipe benders.
How does a pipe bender work?
The operating principle of this device is simple: a profile pipe is placed between three support shafts. The central shaft creates pressure that bends the metal at the desired angle.
A pointing machine is used to bend the pipe in one local area.
Profile pipe bent on a point device
If you need to get an arched profile, then use a rolling bending machine that combines metal bending with broaching.
Types of pipe bending machines
Depending on the drive that transmits force to the profile metal, there are three types of pipe benders:
- mechanical (pressure is created manually using a central screw or lever);
- hydraulic (a hydraulic jack is used);
- electric (bending force is created by an electric motor);
- electrohydraulic (the hydraulic cylinder is driven by an electric motor).
Point mechanical pipe bender
Mechanical rolling profile bender (the screw creates pressure on the profile, broaching is done using the central shaft and handle)
It should be noted that a rolling pipe bender with manual profile pulling is designed for small cross-section pipes (maximum 40x40 mm). It is impossible to stretch a large profile manually. To bend it use powerful machines with electric broaching mechanism.
Manual rolling bending machine (broaching is performed by the outermost rollers driven by a handle and chain, and the pressure is created by a screw and a central shaft)

How to make a bending machine with your own hands?
The basic principle that should be followed when developing a drawing for a homemade pipe bender is maximum simplicity of design and reliability.
Option 1
A machine for point bending can be assembled from two pieces of channel, four corners and two trimmings of fingers from tractor tracks.
Pipe bending in it is performed by a standard hydraulic jack with a force of at least 5 tons. A steel “shoe” is installed on its working rod. You can order it from a turner or make it yourself from an old pulley, the width of the “stream” of which is equal to the width of the profile pipe. By cutting off a half from the pulley and drilling a seat for the jack rod in it, a hydraulic drive mechanism is obtained.
bed homemade device consists of four corners (60-80 mm shelf) welded to a steel plate. Two channels are welded in parallel to the upper ends of the corners. Holes are drilled symmetrically in their walls to adjust the bend angle of the workpiece.
To working position manual machine for bending a profile pipe is given very simply:
- Two steel fingers are inserted into the holes on the channel and stop rollers are placed on them.
- The jack with the shoe is raised so that a profile pipe passes between it and the stops.
- Having installed the pipe, use the jack handle to create a bending force.
Video of the assembly and operation of a point pipe bender:
Option 2
It is also quite possible to build a rolling manual pipe bender for a profile pipe on your own. To make it, you will need 2 linear meters of channel (wall height 15-20 cm), from which the base and racks are cut.
To make the rollers, take six short pieces of steel pipe. It will act as a cage for bearings. Therefore her inner diameter must be equal to the outer diameter of the bearing. Having ordered three shafts from the turner for attaching the bending rollers, they begin welding the frame.
For the machine under consideration, the role of a guide setting the angle of bending of the profile is played by the rightmost support. It is mounted on a channel, pivotally connected to the main frame using conventional door hinges. The jack's working rod rests against the turntable and lifts it.
By rotating the handle mounted on the intermediate stop shaft, the profile is pulled through the machine.
You can adjust the bend radius of the profile not only by tilting the rotary channel, but also by using the outermost rollers. To do this, they are not tightly welded to the frame, but made movable (holes are drilled in the channel and support plates).
Instead of a hydraulic jack, you can use a screw automobile jack to lift the end drum.

Pipe bender is a necessity in household a device with which you can make a frame for greenhouses, bend pipes for gutters, sewers, and perform many other similar works. Exist Various types These devices are classified according to their operating principle and the shape of the pipe they can bend.
At home, you often need to bend a profile pipe yourself, but what to do if you don’t have special equipment for this? There is an exit! You can make a universal manual pipe bender (aka profile bender) with your own hands from scrap materials. Read our article for more details.

How to make a pipe bender with your own hands - main points during development
To make a pipe bender for a profile pipe with your own hands, you will need drawings and some equipment. Let's look at how to collect different variants such devices.
Crossbow pipe bender for round pipe
The most popular are mechanical, hydraulic and electric crossbow-type pipe benders. They use a special nozzle, the diameter of which varies depending on the size of the communication. It is designed for cold processing of metal products round shape.
As a basis for developing your own crossbow pipe bender, you can use option 4 from the “drawings” section of this article.
Hydraulic pipe bender
Hydraulic pipe benders are used to bend a pipe without filling it, i.e. nothing is inserted into the fitting hole. They are very convenient if you need to deform a square or rectangular section, or without holes. The disadvantages include the fact that due to such an effect the internal radius changes slightly, which is not always acceptable for processing pipes for drainage or sewerage.
Wood pipe bender
The simplest option for thin-walled aluminum pipe is a template flexor. He is simple design from a specific template (made according to the required bend angle) and clamping devices.
Making a template pipe bender with your own hands from wood - step-by-step instructions:
- Cut from a board of suitable thickness definite shape. Depending on the required degree indicator, its angle is measured;
- Afterwards the form is permanently installed on the future rolling table. It is most convenient to mount it with screws, since then the installation can be moved to another place;
- This pipe bender is a lever bender, so you also need to make a handle, which will do the main work;
- The stop is installed at a distance from the template, which corresponds to the diameter of the element being bent, and is secured with screws. He must be motionless;
- The process of working on it is as follows: the product is inserted into the hole between the template and the stop and bent by hand.
This is a simple option, but not ideal, since you will have to make a new template each time. In addition, the angle obtained by such bending will not be entirely accurate.
Making a pipe bender from a jack
The pipe bender design made from a jack is more practical, because you can choose different angles deformation. To construct such a device, you will need a winch, a hydraulic jack up to 5 tons, an engine and gearbox, a plate, and a jumper. This device is semi-automatic, therefore more convenient for domestic use.
First of all, you need to select the base for the frame on which the machine will be installed. You can take simple corners, but with a cross-section of at least 8 mm, so that they can withstand the weight of the product and other devices. The base must be regular table, a jack is attached to it using bolted connections. Then you need to install it on the table according to the drawing or instructions. Instead, you can even use small sections from other pipes.
For bending big pipes A more serious installation will be required, it is called bending. The bend is made from a large-diameter steel profile pipe, a special metal template or other frame of the desired shape. This homemade pipe bender works on a similar principle to the template one, except that you need to use your own physical strength. The jack is connected to the gearbox and motor, the product is installed between the frames and the device is connected to the network. Due to the pressure provided by the jack, the pipe is bent according to the pattern.
Roller pipe bender - step-by-step photo instructions
Similarly, you can assemble a three-roll roller tool, only in this case you need to install several profiles at once, acting as templates. This do-it-yourself pipe bender diagram may be needed in manufacturing complex design, where you need to bend the product in several places at once.
In general, roller pipe benders, I think, are the easiest to manufacture. Below you can see the full step by step photo instructions for creating a roller pipe bender with your own hands.
You will need:
- Electric welding;
- Two 1045 steel rollers (pre-turned): the largest is 100 mm in diameter and the smallest is 60 mm in diameter, both 35 mm thick and with a cavity radius of 12.5 mm (half an inch).
- A tube with a diameter of 1 “1/4 (it will serve as a lever) with a thick wall (the one in the photo is 3 mm) and a length of 1.5 meters.
- Steel strips 4 or 5 mm thick (for the base and for supporting the rollers).
- One 3/4" bolt (for the large roller axle) and another 1/2" bolt (for the smaller roller axle) to screw into the base with an approximate thickness of 50 mm.
- Other hand tools, saws, vices, hammers, calipers, etc.
It should be noted that this machine is designed for bending pipes with a diameter of 1 inch and not for any other diameters! If a different diameter is needed, then other pulleys with the corresponding groove can be machined.
Electric pipe bender
Electric rollers are the most precise and practical, they are used for processing any fittings (square, rectangular, etc.) and pipes. Equipped with an electric drive, which ensures complete automation of the process. The main advantage is high accuracy work and the possibility of deformation of communications from various materials. Electric pipe bending machine Suitable for bending metal-plastic, copper, steel and other pipes.

Video - homemade manual pipe bender for a profile pipe with your own hands
Hello. Today I want to tell you about my homemade pipe bender that I made this winter.
I've been thinking about building a machine like this for a long time. With its help, you can roll profile pipes, giving them an arc shape. This operation is in great demand - you can assemble, for example, a greenhouse, a canopy, a canopy over the entrance. You can give an interesting shape to the top edge of a gate or metal fence...
And this winter I found time and started doing this homemade project. When designing, I considered the following points:
Considering that I am not going to use it professionally, I decided to make a relatively lightweight design, which is also easy to transport and will not take up much space during storage. (After all, I will bend pipes either near the house or at the dacha. I will not use it every year. And I certainly won’t have to bend large-section pipes). Therefore powerful stationary structure With a large resource, I decided not to do it...
There are many descriptions of similar machines on the Internet. Their operating principle is the same - they are based on three shafts, one of which is movable in vertical plane. It is he who bends the pipe and, rolling along these shafts, it takes the shape of an arc.
... Basically, they are all divided into two types:
1. With a “breaking” frame:
2. With a movable central carriage.
The second type is more compact (albeit more complex), so I decided to do just that.
In turn, pipe benders with a movable central carriage are also divided into two types: With a driving central shaft and with two driving outer shafts connected to each other by a drive chain.
If you make the central shaft leading, then it is possible to easily change the distance between the outer ones, which will provide additional adjustment of the work depending on the cross-section (and therefore rigidity) of various profile pipes.
At first I doubted whether there would be slippage if only one drive shaft was used, but after observing a pipe bender with one drive shaft in operation, I realized that for not very large sections this force is quite enough. But I’m not going to bend pipes with a height greater than, for example, 60 mm... That’s why I settled on such a device.
And after some time, I got a pipe bender, which you will see in this video:
So, in more detail... I needed:
1. Old faulty hydraulic jack
2. Profile pipes of various sections.
3. Circle with a diameter of 40 mm, a length of 500 mm.
4. Bearings 6206 4pcs
5. Bearings 6202 8 pcs.
6. Channel No. 65
7. Thrust bearings 2 pcs.
8. Hardware (bolts, nuts, washers, cotter pins)
I started by making the main working elements - shafts. I had a 40 mm round timber, half a meter long. It was possible to take a thicker one, but... I had this one!))). Therefore, I sawed it into three parts. Two - 130 mm each, and one - all that remains))))). On lathe machined shafts for bearings (up to 30 mm diameter)
The shafts are ready. I started assembling the carriage. I decided to make it from the 65th channel - the 206th bearings fit well into it...
After I cut the channel required length, I drilled a hole in its center, and welded it across the sides along the corner:
After that I started making the center screw. I took it from an old hydraulic jack that I found on scrap metal. When I was sure that it would never be a jack again, I decided to use it.
The screw itself had a diameter of 30 mm. I drilled through its end with an 8mm drill blind hole, hammered a pin in there and grabbed it with welding:
The screw in the jack was screwed into the piston. I cut him off top part(with thread) and another ring, 20 mm wide.
I put this ring on the screw, inserted the screw itself with a pin into the hole in the carriage and welded the ring to the carriage:
It will be seat for the support bearing. (I selected it according to the outer diameter)
I screwed a nut onto the stud and drilled a hole in the nut and in the stud:
It was only possible in high heels, but it seemed safer to me. The nut can now be secured with a cotter pin after assembling the assembly. And the assembly, as you guessed, consists of a screw, a bearing, a carriage, a second bearing and a nut.
Now, when pressed, the screw will rest against the carriage through the upper bearing, and when lifted, the carriage will hang on it through the lower one.
On the sides of the carriage I welded a piece of 50 by 20 profile pipe - these will be the guides, and in the corners I drilled holes and cut M6 threads. The bolts securing the drive shaft clamps will be screwed into them.
I cut out the bearing mounting clamps themselves from tin - there is no need for strength there, as long as the shaft does not fall when the carriage is lifted:
Next I started making the top plate. It needs to be made very strong - it will bear all the force of the screw when it bends the pipe. Therefore, I made it from the same 65 channel. Since for the vertical racks I decided to use a 50 by 25 profile pipe (the distance between the flanges of the 65th channel is exactly 50 mm. The racks will fit into it and are secured with M10 bolts and nuts), then the width of the top plate should be 50 mm larger carriage width (2 times 25). I cut two such pieces of channel.
Another one was cut into half and spread lengthwise:
I inserted the threaded part cut from the jack piston into the center:
I cooked everything and trimmed off the excess:
Next, I started making the frame. It was also assembled from a profile pipe. I took the cross section 60 by 30:
I decided to make three positions for each shaft. I also made the mountings for the bearings from a profile pipe, so I cut 12 identical pieces of 50 mm each. (Here, and not only here, mine, which I told you about in a previous publication, helped me a lot):
After which I welded vertical posts and bearing mountings to the frame:
And also four “ears” along the edges. Holes will later be drilled in them for attaching the pipe bender with screws to the workbench.
The main part is ready. You can start pre-assembly:
I welded a piece of 20 by 20 pipe to the screw on top. I left it long. I decided that during the testing process, if it gets in the way, I will cut it off and use a removable lever made of a 15 by 15 pipe, which is inserted inside... But, looking ahead, I will say that this was not required. The lever really interferes with turning the drive handle if it is turned a quarter turn (it sticks out across the pipe bender). But it turned out that tightening the screw at half-turn intervals is quite normal.
Next, I started making the drive handle...I decided to make the handle itself from a 15 by 15 profile pipe and a stud. I drilled a hole at the end, inserted a piece of M14 stud into it, welded it and cleaned it:
Now you need to make a bend on the lever itself - the pipe bender will be installed on the edge of a table or workbench.
Next, connect it to the shaft. I decided in advance to make it not only removable, but also so that it would turn over and in the transport position would not dangle or cling. I made this profile on the shaft:
Then I drilled a blind hole and cut an M8 thread in it. The handle will be placed on the shaft and secured through a washer with a wing bolt.
Now we need to make a hub on the handle. I used corner scraps:
Then, like a sculptor, I cut off everything unnecessary :)))))
The lever is ready. On the handle itself (which I have made from an M14 pin), I simply put a piece of polyethylene water pipe and tightened the cap nut.
In general, I would like to dwell separately on my use of cap nuts. I often use them if I need an axis of rotation. By selecting correct length axle, you can screw in the cap nut and tighten it with maximum force - it will rest against the axle with the cap and will not unscrew easily. Of course, it is not worth fixing the axle on which, for example, a wheel is located, in this way, without a cotter pin, but for “unimportant” axles, such as “curtains” on which something opens and closes, this is quite suitable.
Let's return to the pipe bender... As I already said, such a moment as a very simple reinstallation of the shafts was important to me. (Because, knowing, for example, myself, I am sure that I will not use the option until the last minute if it is difficult to use... For example, if the shafts were close, and a pipe came across with a large cross-section, I would try carefully roll it in this position of the shafts, if to change it you would have to unscrew a lot of nuts... And most likely, it would crush...). That is why I made the bearing mounting points from a profile pipe. The shaft is simply inserted into the right pair racks
But this design contradicted my other requirement - mobility! After all, when moving the machine, the shafts would have to be removed and moved separately... At the same time, the bearings would have to be removed from them (I machined them for a loose fit and they can fall off). This didn't suit me. Therefore, I decided to make a part that would press the bearings from above and fix them. I took two sections of profile pipe, section 50 by 20 mm, wall 2 mm.
After which I cut them lengthwise along the wide part, dividing the wall into 10 and 40 mm. At the same time, on the other hand, I marked this size in a mirror way. I ended up with four blanks like this:
Considering that the width of the 206th bearing is 15 mm, it fits quite tightly inside this workpiece.
I measured the required length, I cut the rest like this:
After that, I bent the upper part down 90 degrees, making a corresponding angle cut:
I cut out this “tooth” on them:
Now I installed both shafts on one side of the pipe bender, put the resulting parts on them, vertical posts, having drilled through, I attached them with long M4 screws with cap nuts (they turned out to be axles). In front, I bent the strips of side walls sticking out towards each other towards each other. Now, if we rivet them together, we will get a U-shaped cover, which, when lowered down, will cover the shaft bearings and fix them tightly:
To every owner of a big garden plot or a small dacha, at least once in your life (at least) you may need a pipe bender - a device for bending a profile pipe.
For example, this could be a blank for a greenhouse frame or canopy, gazebo, or any other metal structure.
Metal sales centers and other industries usually use factory-made devices, but this pleasure is far from cheap. To save your budget for more pleasant expenses, it is more profitable to make the device manually, on your own.
For this design, as they say, “you don’t need a lot of intelligence,” and there won’t be a shortage of parts either; you can actually create the drawings of a pipe bender yourself.
Pipe bender options
You can bend the pipe using the “home” method, fill the pipe with sand, heat it until red blowtorch or gas burner, then bend the pipe. This method is not recognized as a priority among craftsmen; it is labor-intensive and does not provide sufficient accuracy; creases and deformations may also appear.
To get perfect bent pipe, in compliance with the standards and specified parameters, do not cause damage source material, craftsmen use specialized pipe benders in their work.
Lever-type pipe benders have become very popular. This elementary invention works on the principle of a “lever” - the force is concentrated in a certain place, and the bend merges with the shape of the template you created, which can most often be removed and replaced with another.
Most often, a set of such designs includes a couple of additional templates for pipes different diameters. There are units of similar design, manual pipe benders, drone or crossbow benders, they allow you to bend short sections of round steel pipes, subjecting only to cold processing.
Crossbow devices are very compact and are valued in the field of installation and engineering communications.
What is the job of a pipe bender?
The principle of operation is completely simple, it consists in heating the pipe, the pipe heats up red and becomes very plastic, malleable to change. Each type of pipe bender has its own range of capabilities.
The main functions are the quality of bending and the ability to bend pipes different sizes and diameter.
With the help of additional rolling devices, a bend of a larger diameter is achieved. The device operates using shafts, there are three of them in the set.
Guides and pressure. The pipe passes through moving elements, the degree of bending is set by the force of the pressure roller. If the radius of curvature finished product turned out to be small, the procedure should be repeated.
Bending a pipe according to a template
In most cases, the simplest option, suitable for absolutely all craftsmen, even beginners, is a wooden template. Boards are selected according to the thickness of the pipes being bent; be sure to leave a couple of centimeters of board space.
To prevent the profile from moving off the template during operation, a slope is left at the ends. The template is rigidly fixed to the floor or other stable surface, and a stop for the pipe is installed nearby.
The profile is inserted into the gap between the template and the stop, smoothly and carefully press on its other end, pressing the pipe against the template. A winch or lever will make the job easier.
A huge advantage of this process is cost savings and ease of execution.
Note!
Any device has disadvantages, and this method is no exception. The bending is not accurate Bad quality, and the template will be disposable (apply only to one pipe diameter).
Snail pipe bender
When stamping identical blanks in large quantities with a small radius of curvature, a snail pipe bender will become indispensable.
Its advantage is its small size and ease of operation. The disadvantage will be the limitation of the radius of curvature, but not large sizes.
Rolling pipe benders
The niche of versatility and practicality is occupied by hand-made devices - rolling pipe benders ( bending machines), on such machines you can make any bending angle.
The configuration is not particularly different from other models; they also have a base and shafts. The movable roller presses the pipe, and it is pulled through by the rotation of the drive shafts.
Note!
Pressure can be increased using a winch, levers or electric drive. However, for the production of a house, such a design is quite complex to implement.
To reproduce such a unit, many turning and welding work. If you decide to make such a model, it will serve you for a long time and will delight you with its functionality.
How to make a pipe bender with your own hands, the question is modern world quite relevant. To make the task easier, you can find a photo of a pipe bender on the Internet to roughly understand what it should look like.
There are also many pipe bender drawings that are easy to use. After reviewing all the information and assessing your strength and the availability of the necessary components, calmly get to work.
