Do-it-yourself manual pipe bender: diagram, materials, manufacturing. How to make a manual pipe bender with your own hands. From this article you will learn several ways to make a manual pipe bender correctly.
It is not always possible to lay pipes exclusively along a straight path - bends and turns of different angles along the entire length of the pipeline are inevitable. In this case, all pipes go on sale mainly straight, which is why it becomes necessary to bend them to specific parameters yourself.
It is not possible to do this manually, especially if the products are profiled or made of durable metal. That is why there is a special device - a manual pipe bender, which almost any craftsman can make with his own hands.
Find out how to properly assemble such a tool with your own hands in this article.
Why do you need a pipe bender?
To understand why a household still needs a manual pipe bender and what kind of work it can be useful for, we will highlight just a few of the most popular options among all the possible uses of bent pipes - these are:
- installation of engineering systems - sewerage, water supply, ventilation and air conditioning;
- installation of fences and nets on the site;
- design and assembly of garden furniture;
- creation of greenhouses;
- installation of a carport. Important! Depending on the required volume of bent parts and the complexity of the shape, choose the appropriate pipe bender option. This can be the simplest manual pipe bender, profile or hydraulic, the use of which is advisable for changing the type of steel pipes. The latter option will also help you quickly complete the task if you need a large number of non-standard parts.
What pipes can be bent?
There are no restrictions here if the tool is chosen correctly. You can obtain the desired shape of parts by using pipelines from:
- plastic;
- aluminum;
- become;
- metal-plastic;
- copper Important! The choice of a suitable device for bending pipes is greatly influenced by the cross-section of the pipeline itself and its profile. For example, it is much easier to give the desired shape to ordinary round elements of the future system than to profile ones, preventing their deformation or complete breakdown.
What does a typical manual pipe bender consist of?
The configuration of a manual pipe bender system will vary depending on the specific type of tool. But at the same time, any homemade manual pipe bender will definitely have:
- frame - open or closed;
- top bar;
- bottom bar;
- hydraulic cylinder - if these are hydraulic systems;
- 2 stops. Important! In more complex devices, the design of a manual pipe bender implies the presence of a special power injection device, which is mounted on the back of the housing. In addition, bypass valves and handles can be added to ensure the most convenient and efficient use of the tool. If a manual pipe bender is made with your own hands from metal parts - gears, shafts, in order to prevent them from rusting and compromising the integrity of the external contour, a special compartment for supplying oil and lubricant is also installed. All parts are often held together using bolts, screws and nuts, but in some cases locks and even welding will be required.
How to bend a pipe correctly?
To avoid wasting material, the first thing you need to do is familiarize yourself with the minimum allowable bend radius of the pipes you plan to use.
When calculating this indicator, the wall thickness, features of the material itself, as well as the diameter and profile are taken into account. Find such data before you start making a manual pipe bender with your own hands.
Below is a table of the minimum bend angle for commonly used metal pipes - please read it carefully.
Important! If you do not comply with these requirements, you will not be able to achieve the desired bending quality and the pipe may simply break during processing.
How to make a manual pipe bender?
Select the pipe bender option that suits you from the DIY assembly methods suggested below. Before you begin, make sure you have all the necessary materials and tools, and also carefully review the drawings of the manual pipe bender.
How to make a manual pipe bender: method 1
Choose this method if your main requirement is high equipment performance. To make a manual pipe bender using this method, follow these recommendations:
- Take a suitable metal base.
- Secure it to a stable, level surface.
- Drill holes at the ends.
- Take metal rectangular or trapezoidal plates and drill holes in them to secure the shafts.
- Secure the metal plates with a screw and nut.
- Install rollers of suitable diameter into the resulting grooves.
- Securely secure them with studs and nuts.
- In the center of the base, attach several vertical profile square pipes by welding to form a stand for the third - deforming shaft.
- Secure it inside with a pin and nut.
- Attach a handle made of a metal round pipe to one of the shafts at the ends.
Important! As a result of the work done, you will have a design like the one in the proposed photo. You can simplify the design as follows - do not use additional material for the base of the body, but immediately screw the plates and central posts to the very base on which the tool will stand.
How to make a manual pipe bender: method 2
The previous version of the design is quite complex. It requires a preliminary clear design and the correct selection of materials to obtain a truly effective result. The next method is the simplest design option, which will allow you to easily give the desired shape to pipes with a cross-section of up to 25 mm.
Do the job as follows:
- Create a drawing of a manual pipe bender to determine the template parameters you need.
- Take any boards or other lumber that you have left over from previous construction projects.
- Cut them to the desired size, focusing on the parameters of the previously created model in the drawing.
- If you only have small boards available, make several pieces to connect them later.
- Fasten all the elements in any way convenient for you - nails, screws, self-tapping screws.
- Attach the resulting module to a table or any other base on which you will bend pipes.
- Attach a small block to one side of the template, which will serve as a stop for the pipe when changing its shape.
Important! When choosing the distance between these elements, be guided by the thickness of your pipe so that you can insert and fix it. To use such a pipe bender, take a pipe, place it between the stop and the template model, and carefully bend it. Please note that you need to change the shape of the product from the end, and not from the center. If you ignore this rule, you will not be able to maintain the parameters of the bend trajectory, and the pipe may burst with this approach.
How to make a manual pipe bender: method 3
Another option for a very simple design of a manual home pipe bender, which you can even use to change the shape of profile products with rectangular and square sections.
Progress:
- Take a large sheet of plywood.
- Mount it on a wall convenient for you.
- Get some metal hooks.
- Determine the arc you need.
- Draw a line with a construction pencil.
- Secure the hooks clearly along it using screws and nuts.
- Attach small metal plates to each hook as clamps - thanks to them, the pipe will not slip out of the tool while doing the work.
Important! You can immediately use a concrete wall as a base, but then it will not always be possible to take advantage of the main advantage of such a pipe bender - the ability to change the bending radius for specific tasks.
Please note that you can use such a tool for bending pipes of any strength and ductility. For example, to get the desired result when working with metal products, it is enough to use a hand winch to increase the power supply.
In this case, the work is done very quickly.
Conclusion
In addition to these methods, you can use other design options for a manual pipe bender - there are quite a large number of them. Here is another drawing of a manual pipe bender from quite convenient options:
To clearly understand another design option, the principle of assembly of such a tool and operation, watch the video review below of a homemade manual pipe bender.
When choosing the option that suits you, be guided by the level of your professional construction skills, how often you expect to use a pipe bender, and how much parts you need to prepare. Give preference to the one that will be most convenient for you to work with and will not require additional costs for materials for assembly.

How to make a pipe bender with your own hands
You don't have to bend pipes every day. For example, what to do if you urgently need a greenhouse for flowers? You have pipes, but they are straight, and you can’t shape them with your bare hands. In this case, you will need a pipe bender. Let's figure out how to make a pipe bender with your own hands, what kind of device it is and what it is needed for.
Features of pipe bending machines
Profile pipes are used not only for greenhouses. They are used to make fences, garden furniture, shelters for cars and greenhouses. They are used to build garages and lay pipelines. The manufacturing technology of any of these products involves bending the pipe at a certain angle.
Here you will definitely need a pipe bender - a device that can bend a pipe of any configuration (gas, boiler, water supply) and from any material (aluminum, copper, steel and metal-plastic).
The bending angle can be up to 180 degrees, provided that the pipe size does not exceed 2 inches.
In this case we are talking about a device with a hydraulic or mechanical drive. Most often they are used in gas stations and boiler houses, in industry and tuning. How to make a pipe bender for a profile pipe yourself, we’ll figure it out further. After all, as mentioned above, you can’t do without it at home.
Manual pipe benders are used for bending arcs and rings
Product design
The design of pipe benders is not always the same. And it all depends on their variety. The main parts of any design are always a hydraulic cylinder, a frame, lower and upper bars, as well as two pipe stops. The frame can be open or closed. The hydraulic cylinder is the main part of the machine, which performs the power function.
A manual pipe bender has a pressure device located in the rear part of the body, where there is also a handle and a bypass valve screw. The oil fill plug is located on the top of the hydraulic cylinder. The oil level is controlled through it. The lower strip is screwed onto the threaded part in front of the body and pressed with a fixing nut. The top bar is secured with a lock and two screws.
The bending force of the machine is provided by a rod, which has the ability to extend and return to its previous position thanks to a spring installed in the hydraulic cylinder. The lower and upper bars are made as a welded structure, and holes on the transverse plates are used to install the stop. There should be threaded holes at the bottom of the machine for mounting bolts that can be used to adjust the height.
To make a pipe bender with your own hands, you must take into account that its stop is in the form of a pin, the ends of which are located in the holes of the upper and lower bars. In the middle of the stop there is a stream on which the bent pipe should rest. The bending element is made of precision cast steel. The drive of a manual pipe bender can be hydraulic or mechanical; the drive of a power tool, accordingly, will be electric.
Manual pipe bender support roller system
Most often, profile pipes with thin walls are used, which make it possible to create durable and aesthetic structures in construction, while saving metal. It is convenient to make canopies, greenhouses and canopies from them.
The profile cross-section can be square, rectangular or oval. Therefore, the design drawing of a pipe bender for a profile pipe provides for the selection of parts accurate to the millimeter.
Do-it-yourself pipe bender rollers must be selected with the same cross-section as the product in order to prevent deformation of the cross-section of the pipe.
Types of machines
They are used for bending arcs and rings. The average weight of the machine is 65 kilograms, which allows you to move it from place to place and work with light metal structures (wickets, gates). The parameters of the materials processed by a manual pipe bender are as follows: round pipe 30 mm, square pipe 40 by 40 mm, strip 40 by 10 mm, square 16 by 16 mm and rod 16 mm. You can expand the range using different mandrels and thus obtain a profile bending machine.
They are capable of bending pipes of different sections, which is why they are intensively used on an industrial scale. Since electric pipe benders have high productivity, they are equipped with additional functions. This allows you to control the machine using buttons and pedals, as well as change the mandrels to match the configuration of the diameter and cross-section of the pipe.

- Hydraulic manual pipe bender
This is a modernized version that is designed to work with large-sized steel pipes. The machine is used when removing or installing water and gas pipelines. Its hydraulic drive has great power and greatly facilitates the operator’s work.
According to their purpose, such pipe benders are divided into several types. Some are for fittings, others are for pipes. For example, a TPG (portable hydraulic pipe bender) is used for rolling round sections and bending solid steel pipes.
RGU (manual pipe bender) - designed for bending entire pipelines, fittings or rolled products.
Pipe benders are also differentiated according to operating conditions. Those that are used in enterprises most often refer to stationary machines. An ordinary hand-held device is also suitable for home use. And you don't have to buy it. You can make such a manual pipe bender with your own hands in a short time. The main thing is to study the drawings and understand in detail what is needed for this.

How to make a pipe bender at home
As mentioned above, making a pipe bender with your own hands is not a difficult task, but it requires certain knowledge. First you need to select the material and make a base for the entire machine. After all, the machine will have to withstand different loads, and such a unit is not made just once.
If you make mistakes during the manufacture of the machine, then during bending you can damage the material that is being shaped. Of course, creases, cracks and other defects during bending can also appear due to the poor quality of the metal.
But you can reduce the level of risk by making a mandrel pipe bender with your own hands from the strongest materials.
Making the base
For the base you will need a pipe with a rectangular cross-section and fairly thick walls, at least 3 millimeters. When a suitable pipe is found, it is necessary to drill a hole in it for the future axle. To do this, step back a few centimeters from the cut, first measure the diameter of the axis and make a hole of the same size.
A pulley will then be installed in it, around which pipes and a handle with a working pulley are bent. At this stage, it is very important to determine the maximum bending radius of your machine.
Add another 5 centimeters of reserve to the radius value, and also retreat a distance equal to the size of the larger side of the pipe, make a mark, then cut it.
The pipe bender drawing provides for the selection of parts with millimeter accuracy
The pipe clamp (lever) is a pin to which a wing nut plus a lock nut is welded on one side, and a T-shaped clamp on the other (the leg of the letter is the pipe, and the longitudinal section is the transverse part).
Next, you should make a handle for the pipe bender. It is made from two metal plates with a thickness of at least 4 mm. The width of the handle should correspond to the diameter of the axis of the frame, because it is on this part that it will be put on.
But for reserve it is necessary to leave 10-12 millimeters on each side.
To give rigidity to the handle, these plates will need to be connected by welding with several steel jumpers from opposite ends. Now that the base is ready, let's figure out how to make a pipe bender for a profile or round pipe with your own hands so that it is also suitable for metal-plastic pipes.
To make the machine universal, secure its base tightly with a vice
Assembly of the structure
To make the machine universal, secure its base tightly with a vice. Next you need to put one of the unit handle plates on the axle, then the second plate and the main pulley. The retainer pin should be screwed into the wide nut on the base. The pulley is fixed on the base axis with a tightening bolt.
The next step is to test the pipe bending machine. Take the pipe, place it in its original position, press it against the pulley and screw in the lock. When the pipe is firmly clamped with a special clamp, it should take the required bend shape.
If you have little experience in this matter, pour sand into the pipe before bending it, and after finishing the work, pour everything out of it. This will protect your product from deformation.
Now that you know how to make a pipe bender yourself, you can safely start any construction project.
