For a home master with the right approach, it will not be difficult to assemble the pipe benders for the profile pipe with your own hands. Of course, you can buy this important tool in any specialized construction shop, but not everyone can spend extra money on pipe benders, especially if you need to bend just a few pipes.
At home the master at any time it may be necessary to bend several pipes, especially as the pipes are used not only for water pipes or gas pipelines.
From them you can make various gazebos or greenhouses, fences or canopies, as well as many other interesting things.
In any case, if you make a pipe bender with your own hands, it will allow the master to save money and have a handy tool at hand that will find wide application in the household.
In general, the bender is a special device that is used for bending pipes of different materials of various diameters, including round metal-plastic ones, at the required angle.
A simple homemade pipe bender can be made from improvised materials, although it is best to have a corresponding drawing next to it.

Basic concepts and types of tools
Basic concepts and types of tools
Before making a pipe bender with your own hands, you first need to understand the, what kind of tool is it and what types of it?
Modern industry produces this tool with a different kind of drive, which differs among themselves in the way of bending.
The homemade bender will certainly be slightly different from the professional, but the principle of its work will remain the same.
In addition, it should be noted that these devices can have both manual and electric, and hydraulic drive, which operates on the principle of a jack.
Manual bender, which is presented in the photo below, is usually used to impart the necessary shape and bending to metal-plastic pipes, as well as pipes with small diameter, made of non-ferrous metals and having a relatively small diameter.
In turn, hydraulic bender is a fairly versatile unit, which allows you to carry out the necessary work with virtually any pipe material.
More professional devices have electromechanical control, which allows you to work with different pipe diameters, while ensuring the maximum accuracy of the angle and bend radius.
This tool allows you to work, including with thin-walled material without any defects and deformations.
The main indicator of any tubular bending is its way of bending and in this case there are crossbow, spring, as well as segment and dorn ones.
Crossbred benders are equipped with a special bending element, which has a certain shape, designed for certain pipe sizes.
Spring devices are more suitable for metal-plastic pipes and the main working element is a spring in them.
In pipe bends of segment type, the bending of the pipe occurs by pulling it around a special segment.
There are other indicators that affect the operation of this device, and in order to assemble the self-made pipe bender, which can be seen in the photo below, all this should be taken into account.
Hand-type bender
The simplest work pattern for a hand-type pipe bender. If this tool is correctly assembled and in accordance with certain rules, it will be able to provide the required bend radius.
In order to make a manual pipe bender with your own hands, it is best to have at hand an appropriate drawing with a detailed description of each of its elements.
It should be noted that such a tool can later be used for bending of metal-plastic and aluminum pipes, as well as for steel pipes.
First you will need to make a template.
To do this, take boards, the thickness of which will slightly exceed the thickness of the pipes, which are required to bend and cut out the corresponding workpieces.
After that all the boards are fastened together, as required by the drawing. It is best to do a slight slope on the boards when sawing.
This will allow later in the work to avoid slipping the pipe from the template.
After the template is fully prepared from the boards, it should be firmly attached to a base, for example a table.
Then, on the base directly next to the template itself, a special stop is fixed, into which the pipe itself will rest.
For more details on how to assemble the most simple hand-type pipe bender, see the video below.

If you have any difficulties when working on this device and the pipe will not go well for bending, you can use an ordinary hand winch, which will greatly simplify the task.
When assembling this unit, special attention should be paid to the strength of the fastening, both the wooden template itself and the stop.
They should not break down or get out of their place in the process of work under external force.
Manual pipe bender for profile pipe
It is known that it is more difficult to work with a pipe of profile type, and therefore the pipe bender for it must have a reinforced structure.
You can use the drawings for its creation, as well as for the elementary device of a manual type, but with minor modifications.
In this case, it is not necessary to make a bevel on the wooden preforms intended for the template.
In addition, for additional fixation of the pipe workpiece, additional restraints should be installed, as shown in the photo below.
Also, under the profile pipe with their own hands it is possible to assemble a small rolling device made of wood, the scheme of which will be as simple as possible.
It should be noted that wood blanks can be used for making rollers, however, it is best to use ordinary bearings or polyurethane for these purposes.
In the event that bearings are taken for the rollers, they must necessarily be wedged, since they do not have to turn.
The main difficulty in the production of pipe benders by our own hands is that the pipes themselves are flexible.
If you have to work with tubular material, which goes well for bending, then for the manufacture of the device you can use mainly wooden components.
If the pipe has high strength characteristics and is poorly deformed, more durable components, for example made of metal, should be used to make the pipe bend with one's own hands.

Therefore, before you start the assembly of the tool yourself, it is necessary to determine as precisely as possible the material with which you will work, and, based on its strength characteristics, to select the components.
In any case, the device must withstand all loads and provide the required bending angle.
Hydraulically operated bender
It is easiest to work with almost any type of pipe using a hydraulic pipe bender, which can also be assembled by hand at home under the hand of the corresponding drawing.
In this case, a prerequisite is the presence of a jack at hand, as well as a channel. In addition, you will also need two identical rollers, several metal plates and a shoe.
To begin with, the weld channel should be assembled with a weld in the form of a rectangle, the height of which should correspond to the maximum height of the jack.
Further it is necessary to fix as much as possible a jack on the basis of one of channels, and it is necessary to do it with the help of metal plates.
The role of the jack in this type of pipe bender is to perform the necessary pushing function, and therefore it should be designed for work of not less than five tons.
When selecting rollers, one should take into account the fact that they must clasp the tube blank as much as possible. In this case, it is best to consider the possibility of replacing the rollers if necessary.
This will increase the versatility of the device and will allow working with pipes made of a wide variety of materials and having different diameters.
For more information on how to build a device of this type on your own, see the video below.

It should be noted that the pipe bender, assembled from a jack, with the relative simplicity of its design and the minimum of components that are required for its manufacture, has a number of advantages.
With its help it is possible to work with steel pipes in cold condition. In addition, it will be indispensable in the conduct of sanitary and auto repair works of almost any complexity.
Tips and tricks
Almost all kinds of pipes can bend, not only for the manufacture of a frame, but also for laying a water pipe or sewer.
In this case, it should be noted that almost every mechanical joining of pipes with each other is one of the weakest places, which means that the less is in the system, the better.
Of course, the pipe, depending on the material of manufacture and its diameter, is deformed in different ways, and here the main criterion is such an indicator as the minimum radius of bending.
This indicator is a reference and if necessary it can always be found in the relevant literature.
When working on any type of pipe bender, you must always take into account the above indicator.
Otherwise, an excess of voltage can lead to the destruction of the pipe surface, which can lead to serious consequences in the future.
If the volume of work is small and the pipes have a relatively small diameter, the pipe bender should be most conveniently made of wood billets.
A device made of concrete slab will become more qualitative and durable. To do this, you should choose the appropriate size plate and mark the grid on it.
Next, carefully drilled holes for the reinforcement, into which strong metal pins are driven.
If necessary, conduct a given bending of the pipe, it is inserted into the space between the pins and bent in the desired direction.
It should be noted that this device allows you to work with pipe billets, the diameter of which does not exceed twenty-five millimeters.
Also at home, you can assemble a roller bender. Despite the fact that it is not easy to assemble such a device, it is much easier and more convenient to work on it.

It functions on the principle of rolling mill and allows you to bend pipes made from different materials.
In any case, there are many options to make universal pipe benders and every master will be able to select without problems the one that will be in his power.
