How to use homemade machines and tools for your home workshop

The use of homemade machines and devices for the home workshop is aimed at solving several problems:

• Simplifying the metal processing process. When creating household items, a metal cutter or press is often required.
• Improving wood processing. Even to build small shed or make it wooden, others are needed.

Buy ready-made tool quite expensive, so the use of homemade machines and devices for the garage is becoming more and more relevant every day. Among the most common options home tool highlight:

• carpentry workbench;
• device for quickly sharpening knives;
• device for sharpening metal drills;
• drilling machines;
• press;
• cutting disc machines.

Here are a few photos of do-it-yourself tools and devices from “homemade” people:

Practical DIY tool shelves

Before creating devices and with your own hands, determine the storage location of all devices, so that later you do not have to search throughout the workshop or where everything is. It’s not difficult to make a shelf for tools with your own hands; the main thing is to decide on its dimensions and material of manufacture.

The easiest way to make shelves is to assemble them from wood. Do not forget about the need to coat the finished structure with a protective varnish or to prevent rotting and swelling of the wood.

You can create a combined version from a metal support and wooden shelves. Here detailed instructions to create such a homemade model:

We make a carpentry workbench with our own hands according to the drawings: video instructions and photo examples

Among the common do-it-yourself devices is a workbench. Durable and dimensional, allowing you to securely fasten the workpiece, useful for high-quality cutting of wood and creating various elements from it.

The device package includes:

1. Working surface. Hard is used for it to increase the service life of the device. The thickness must be at least 6 cm.
2. Supports. Collected from wooden beams or metal plates. the main task– ensure stability of the entire mechanism.
3. Vise for securing the product. If the table is long, you can install two vices at once.
4. Tool box. Useful recess or retractable design, providing quick access to necessary small parts.

To assemble a carpentry workbench for your workshop yourself, you should choose a drawing and purchase materials for the work.

DIY carpentry workbench drawings

Before purchasing materials to assemble your own workbench, you should think about a detailed drawing. It should include the dimensions of the machine itself; it is advisable to note the dimensions of the materials used and their quantity.

For example, finished drawing A DIY folding workbench may look like this:

Whatever model you choose to create, take into account several features of the workbench that ensure ease of cutting wood:

• height and length of the master’s arms: the height and width of the tabletop depend on these parameters;
• which hand is working: place the vice on the right or left;
• what blanks will be made: choosing the shape of the table;
• how much space in the room do you allocate for the workbench?

Taking into account all these parameters, it will be easier for you to decide on the drawings of the carpentry workbench and the dimensions of the machine. Here are a few interesting examples:

Instructions for assembling a wooden workbench with your own hands

You can buy a wooden workbench in a store or through online catalogs, but it’s cheaper to make it yourself. Let's take as a basis a simple option with standard sizes tabletops: length – 150-200 cm, width 70-120 cm.

The manufacturing work will include several stages:

Image	What need to do
	Make the top cover from thick ones to make a shield with a width of 70 to 200 cm. Fasten the elements with long nails, and you need to drive them in from the outside and carefully bend them from the inside. The working surface of the workbench is made only of wood or.
	Sheathe the lid along the lower perimeter with a 5 by 5 cm beam. This will make it more convenient to attach the vertical supports. The location of the supports depends on the size of the tabletop. It is better to make them from thick rectangular timber at least 120 by 120 mm.
	The carpentry workbench must be installed correctly. Be sure to secure it firmly. If it will be mounted outdoors under a canopy, dig holes for supports. Indoors, use other fastening methods.

When the structure is assembled, install a vice on it. To fully understand how to assemble a carpentry workbench with your own hands, watch the video:

Making a carpenter's vice for a workbench with your own hands

Professional “homemade workers” assemble not only tables for work, but also vices with their own hands according to drawings. Any design of such a clamp will include several elements:

1. Supports, where each one has a sponge for clamping.
2. Moving jaw.
3. Metal guides. The sponge moves over them.
4. Lead screw for moving elements.
5. Collar. Necessary for rotating the screw.

When making a homemade vice with your own hands, you can use various available materials. For example, there is a design option made from a profile pipe. To do this, prepare several pieces of pipe different sizes, steel stud with coarse thread and double nuts.

Instructions for creating a bench vise from a profile pipe:

Image	What need to do
	The largest pipe acts as a body. Supports are soldered to it from below. A 3-4 mm steel flange is put on the back side. A hole is drilled in the center for running nuts, and opposite the front support there is a rear sponge.
	There is a front steel flange on the internal moving part. A stud is mounted in it, with lock nuts attached to it. Thrust washers are placed on both sides of the flange. The last element is a movable tube attached to the front jaw.

DIY metal workbench drawings

A metal workbench does not differ much from a carpenter's workbench. The base is hard metal, not wooden frame. A vice is attached to it, and the entire workbench is designed to withstand the force of a sledgehammer.

Do-it-yourself metal workbenches can have one, two or three cabinets, and also not have shelves and drawers for small parts. In terms of strength for working in a garage, you can make regular table made of metal up to 5 mm thick and reinforced structure, where sheets from 10 to 30 mm are applicable.

Here are some useful drawings for making metal workbench for your workshop:

How to make a device for sharpening knives with your own hands: drawings and photo examples

No home is complete without a knife in the kitchen. It is quite difficult to do it correctly without special devices: it is necessary to comply desired angle and achieve perfect sharpness blades.

For each knife, a certain sharpening angle must be observed:

1. A razor and scalpel require an angle of 10-15⁰.
2. Knife for cutting bakery products – 15-20⁰.
3. Classic multifunctional knives – 25-30⁰.
4. For hunting and hiking, take a device with a blade angle from 25 to 30⁰.
5. If you want to cut hard materials, then sharpen at an angle of 30-40⁰.

To ensure the desired angle, it is worth buying or making a sharpening device. For example, you can assemble a sharpener with your own hands.

A comment

Tool selection specialist at VseInstruments.ru

“If you don’t use sharpening every day, then 1000 rpm is enough for a high-quality result and long term operation of the device."

To assemble such a machine, you will need a motor from a washing machine with a power of 200 W. To create a sharpener from an engine, prepare:

• the motor itself;
• metal for the casing with a thickness of 2 to 2.5 mm;
• flange tube;
• sharpening stone;
• nuts;
• trigger mechanism;
• cable for connecting to the electrical network;
• corner made of metal or wood for the frame.

You can watch a step-by-step description of the manufacture of the machine in the video:

There are simple sharpening machines with your own hands without engines. For example, you can make a device from bars. To do this, prepare two abrasive stones of the same size and a sharpening stone.

The progress of work on creating such simple device will be as follows:

• Sand the wood blocks sandpaper, removing burrs. Make markings depending on the desired angle.

• Attach a stone to the drawn line to give the blade a sharp edge. To do this, attach it to the block and mark its width. Then, make cuts on the markings, up to 1.5 cm deep.
• Attach abrasive stones to the resulting recesses so that the grooves coincide. Then, install the sharpening stone by screwing it onto the bolts.

There are many ways to make a homemade knife sharpener. Choose the one that suits you and try to create a convenient and useful tool for your home.

How to make a device for sharpening a metal drill with your own hands

They make their own not only a sharpener for blades, but also a machine for drill sharpening on metal. Here are a few drawings useful for work:

To understand how to correctly assemble your own drill sharpening machine using the drawings, watch the video on the topic:

The simplest and most common version of such equipment for a garage is a converted drill. To work you will need:

• base frame;
• rotation mechanism;
• vertical stand.

For the rack, they usually use either boards. The drill is lightweight, so there is no need to use metal. In this case, the frame must be made massive in order to reduce vibrations during operation of the device.

To properly connect the frame and vertical stand, and also assemble all the equipment into one whole machine, pay attention to the video instructions:

The production of metal parts requires special equipment capable of creating a force that forms the configuration of the object. Alternatively, you can purchase relatively inexpensive devices. However, it is not difficult to independently make almost any machine for cold forging with your own hands.

We will consider what is required for this during the course of our article.

Of course, if your budget allows, you can not complicate your life too much and purchase universal equipment for cold forging of metal. Moreover, such a machine combines all the individual hand tools. But the rather low cost of such a workbench makes it inaccessible to many home workshops.

What devices can you make for cold forging with your own hands and what can you produce with them?

To start your own metal processing workshop, the main six machines are enough: bender, twister, flashlight, volumetric, snail, and wave.

These home-made machines are capable of processing the main types of materials used in cold metal working technology: squares, rods (with a cross-section of up to 14 millimeters) and steel strip, 3-6 mm thick with a width in the range of 25 millimeters. Self-made devices carry out those the same operations as factory equipment: bending, twisting or pressing without loss of quality.

It is also quite possible to produce the main elements of cold forging products on a homemade manual machine: curls, volutes, baskets required for further assembly finished products. Moreover, the forging equipment itself is compact; it can be easily placed in a garage workshop.

It is very easy to learn how to work with a cold forging tool. It does not require special knowledge about the properties of the metal and its further processing (annealing, tempering or hardening). The training and production process is practically safe; equipment and materials do not work with high temperatures, and the working mechanisms are very simple.

The only drawback to cold forging metal and working with manual equipment is the possibility of defects if mistakes are made. But the main problem is that defects are very difficult to fix. Defective elements can only be corrected by heating the metal in a forge or on a burner.

The easiest for self-assembly There will be: snails, benders and twisters. They do not require expensive tools. All you need is welding, a cutting tool, drawings with materials and a little understanding of mechanics.

So, how to make homemade cold forging machines with your own hands?

Assembly of different types of equipment

For initial stage To set up a cold metalworking workshop, you will need three main devices: a bender, a twister and a snail. What elements can be produced with them?

A bender is a device that greatly simplifies the bending of parts and the production of bends of any shape.

It easily processes rolled steel strip and rod with dimensions of 12x12 millimeters. In addition to corner parts, the bender can create parts with an arc-shaped configuration.

A twister is used to twist a long workpiece around its axis into a longitudinal spiral. In hot forging there is a similar tool - a crank. The twister is similar to this device in its design. This is a frame on which a gate with a rotating head is attached and a slider that limits and fixes desired length details. Parts twisted on such equipment are a common element used to assemble window grilles, fences, railings and other types of fencing.

If you install additional devices in the form of a shaft on the twister, it will be able to produce three-dimensional baskets.

Snail is perhaps the most famous hand-held cold forging machine. Its conductor produces a volute and various parts twisted around an axis. The assembled device consists of a kind of frame (round/square) and a conductor (spiral) and a roller with manual drive in the form of a lever. By pressing the drive lever and feeding the workpiece, you can twist any type of spiral without any problems.

The main thing in the manufacture of manual equipment for cold forging of metal is compliance with three basic principles:

1. The length of the lever drive is calculated so that sufficient force is created on the metal.
2. It is best to make the components of the installations prefabricated or movable, then it will be possible to easily adjust the sizes of the produced elements.
3. All jig parts are manufactured with a sufficient margin of safety, and the connections must be of high quality.

By following these principles, it is quite feasible to produce normal metalworking equipment with excellent performance.

The listed three installations with a manually operated mechanism allow the production of most types of products without heating the metal.

Assembling the bend

This cold forging machine has a wide range of applications. With its help you can bend parts of any configuration. The device is quite simple, it consists of a base on which the rollers are mounted, a wedge (setting the bend) and control levers. The machine itself can be made in a vertical or horizontal design.

It’s easier to make the horizontal type yourself.

• It is necessary to prepare a frame in which mounting holes are drilled for mounting the rollers, wedge and lever.
• The wedge should move along the bed (controlled by pressing the lower lever). Its position should be removable, so it will be possible to adjust the angle and steepness of the bend. To do this, it is better to make it on a screw thread, screwing it in to change the distance of the wedge.
• The upper lever is used to shape the workpiece into an arc.

After watching the video, you can understand how such a machine works and the principle of its design.

Making a snail

The photo shows the main parts of the snail cold forging device. The formation of the element occurs due to a special conductor, curled in a spiral (snail). This part should preferably be two-part. The manufacture of the machine is as follows.

• A frame of round or square shape is prepared. It is better to use 5-6 mm metal for its manufacture.
• Holes are drilled in the base for fastening the conductor (its two parts) and the operating lever.
• A rotating roller is mounted on the side, which will set the movement of the workpiece.
• The lever must have sufficient strength; it can be made from an appropriate profile or pipe (with thick walls).
• The conductor is made of thick metal, bent in a spiral. Holes are made in it for mounting bolts.

Below are photos of the drawings of the conductor and the device itself.

For a more understandable operating principle of such equipment, watch the video provided:

Done manual machines for cold forging with your own hands with such a design they are quite capable of bending rods and squares of different sections up to 14 millimeters.

It is worth remembering that greater force on a thick workpiece can be created using a longer lever, so you can provide an additional extension for such a drive.

There are other snail options. For example, with a drive in the form of a gate located in a horizontal plane. Schematic drawings of such a device are shown in the photo below.

How to make a twister

A twister (or torsion bar) has a horizontal arrangement of parts. It consists of a frame on which a knob with a rotating head is mounted, and a slider that rigidly fixes the workpiece and regulates the length of the product.

• First you need to prepare a workbench (table) where the device will be mounted.
• The frame can be made from a strong I-beam or any other material that has sufficient strength. Its length is selected depending on the parameters of the workpieces being processed.
• A slider is made along the frame. Its lower part should move along the device and be fixed in the desired position. For fastening, you can drill holes for the bolts. The part where the workpiece will be inserted can be made to fit its size ( through hole) or made from a vice.
• A gate with a rotating head can also be made for a specific workpiece or use a chuck from a lathe (small sizes)
• The unit is mounted on the table so that the edge of the table does not interfere with turning the knob.

As with the scroll, the length of the lever determines the force that is created on the metal being processed.

If you make an additional mount for the shaft, then on such a torsion bar it will be possible to produce volumetric baskets by twisting a rod onto a template.

The operating principle of the machine is shown in the video:

After studying the information, you can make devices such as a wave (wavy elements), a flashlight (baskets) or a volumetric element (volumetric elements with parts curved in different planes).

If possible, some of these machines can be made with an electric drive by installing a motor with the appropriate power.

What can you add to this material from your own? personal experience for the production of equipment for cold forging? How difficult is it to make a cold forging machine with your own hands and what materials should you use? Join the discussion in the comments to the article and share your experiences.

A good owner always has his own workshop, which he fills with equipment and devices to suit his needs. Some things can be bought, but others can be built with your own hands. And we must not forget about the garage, because all the necessary equipment should also be there.

It is impossible to provide for everything that might ever be needed. Therefore, we will consider the most basic machines and mechanisms that can be useful when working with wood or metal.

How to make a universal machine with your own hands

There is a huge amount of different types of equipment, many of which in one form or another can be made independently. Craftsmen have even learned to combine several functions in one device.

For example, you can make a universal mechanism from conventional drill which will work like:

• a circular saw;
• grinding;
• cutting;
• sharpener;
• turning.

To make it, you need to attach a drill to the frame. A board with a thickness of 20–25 mm is chosen as the base. The drill is fixed to that part of the body that is intended for attaching another handle.

The location of fixation on the tabletop is selected based on the size of the circular disk, grinding wheel, cutter, or sharpening stone.

To secure the drill, use a firmly fixed threaded rod and nut. Rigidity of fixation is achieved using epoxy glue and, as an addition, a pin 2 mm in diameter. We build a moving sole and that’s it, the base is ready.

To get homemade circular saw, install saw blade 15 cm in diameter onto the drill chuck and make a slot for it in the bed. The saw blade must be protected by a metal casing.

If you plan to use a flat cutter instead of a disk, you need to additionally make a rectangular slot or widen the hole for the saw.

From this “circular” saw you can build a cutting mechanism. To do this, on a rigidly fixed surface we install a rotating bracket, a miter box that sets the cutting angle, guides and devices that secure the workpiece.

We combine this with circular saw on the bed. Grinding and turning machines are assembled using the same principle.

Video: homemade circular saw + plane

Making a circular saw with a frame

If you want to have a separate circular saw, then you can easily build it from a manual circular saw bought in a store. Such homemade mechanism not designed for too heavy loads, but suitable for occasional use on the farm.

We take a frame of suitable size and fix it on it manual circular saw, make the maximum cut and leave it in that position. We turn the base over with the circular side down and place it firmly on the frame with legs.

We make a guide and everything is ready to go. Please pay Special attention to the height of the machine, you should be comfortable working with it, and its height should be commensurate with your height.

You may also need a pipe bender in the workshop. This is a device that allows you to bend pipes from almost any metal, as well as strips. Bent pipes are required when a person decides to make, for example, a greenhouse or a greenhouse or something like that.

There are different types of pipe benders, let’s say, made independently. There are very simple ones, and there are others that are similar in design to factory ones; they are more difficult to manufacture.

We get the simplest version of a homemade pipe bender by cutting a board on one side in a semicircle. Then this workpiece is attached to a stable surface and a limiter is mounted nearby - wooden detail, having a space up to a semicircular blank, into which one end of the pipe is inserted.

Features of homemade devices and equipment

You can talk for a long time about what equipment you can make for your workshop with your own hands. But everyone has their own needs and capabilities. In addition to homemade devices, there should be places to store tools, as well as a workbench.

You should take the construction of a workbench seriously. You need to think about what will be attached to it, where it will stand, and what materials to build it from. The tabletop can be made of metal or wood.

You can immediately attach a circular saw, for example, or a jigsaw, various kinds of vices, clamps, and so on. It all depends on your idea and need for this or that equipment. But the workbench must be needed comfortable height, sustainable and well made.

Also in the workroom, various types of cabinets and pencil cases for placing and storing existing tools, which you can assemble with your own hands, are very useful. You can equip separate places for storing large tools and separately for small ones, for example, a separate open cabinet for drills

How you organize working space, depends on the convenience of work, how quickly you can find the necessary tool or part and, ultimately, your comfortable state of health.

What can be done for the garage

Often, a garage becomes not only a place to store a car, but also for many necessary tools, and sometimes a workshop at the same time. Therefore, here you need to have:

1. Tools for car repair.
2. Spacious racks for their placement.
3. Garage workbench.
4. Hooks.
5. Shelves or brackets for tires.
6. Lamps and heaters.

These devices are easy to assemble with your own hands. The organization of the garage space should be well thought out. Everything should be placed conveniently and not take up much space. Think about whether you need a workbench and where to put it, what size it will be and in what places to place racks and shelves.

A workbench will be needed if you are repairing your car yourself. Typically, all tools are located on shelves and racks next to the workbench. Spare tires are stored either on a special rack or hung on brackets on the walls.

Place all fuels and lubricants on a separate rack. Most often, some difficulties arise with storing small parts: screws, nuts and the like. You can take small ones for this glass jars with screw caps.

Screw the lid to the shelf below, sort all the small items into separate jars. This way you can save space and put things in order, and the search for the right screw, drill or nut will now be reduced to a minimum.

For these purposes, you can choose another option. You will need magnetic tape, small clear plastic containers with durable lids, and metal flat washers. Fix the magnetic tape vertically in the place you need.

Attach metal washers to the bottom of the containers. Sort all the small fasteners into ready-made containers and hang them on a magnetic strip.

For repairs you will also need inspection hole. And if it is not possible to equip it, then you can build two overpasses to lift the front or rear or side of the car. This will allow you to fully carry out all repair operations. Overpasses are made of timber and durable boards or metal if possible.

Well, in the end, it is very important for the garage good lighting. It can be general and as an addition to portable and local lamps. And make sure that there is more than one outlet in the garage. If you are repairing the car yourself, then you need to think about ventilation of the room.

You can make machines for cold forging from scrap materials.

Because universal devices from manufacturers have a fairly high cost, a self-made machine for cold forging of metal will become great solution for people involved in manufacturing forged products.

Today metal constructions With unique design and bold architectural forms are used for furnishing houses in cottage villages.

Figuratively curved forged elements of gates, fences and gates bring an unusual image to landscape design estates.

In the proposed photos you can see what an unusual artistic look metal structures create.

What parts can be made on a cold forging machine?

Cold forging, unlike hot technology, is simple and safe. This process does not require the use of hot metal and precise adherence to operating temperature.

You can make a cold forging machine with your own hands specifically for the production of a certain type of part.

Also, a homemade machine will allow you to solve a wide variety of problems, so it will be simply universal.

By using homemade machine will be able to achieve the ideal geometry of metal elements for individual design idea and make original parts with a pattern yourself.

In the process of cold decorative forging, as a rule, soft metal is used - this can be nickel and magnesium alloys, steel, copper or brass.

Otherwise, the range of products produced on the machine will be limited only by the imagination and ability of the master.

If desired, you can make openwork elements for stairs, gates and fences with your own hands.

The use of decorative details will allow you to decorate fireplaces and barbecues, beautifully decorate the outer walls of the house and gazebo, and make original tripods for flowers, as in the photo.

Types of cold forging equipment

Existing types of machines can be operated with the participation electric motor or manual force.

The first version of the device makes it possible to perform work faster than manual ones, but at the same time requires certain skills from the master.

Forging machines are divided into types:

• snail - a machine with separate removable parts or solid cast - it is used when making spiral-shaped individual parts;
• universal device - used for cutting, riveting and adding volume to the product;
• bender - with its help you can perform arc bending of metal or bending parts at a certain angle;
• device for forming rings;
• twister - allows you to bend the product along the axis;
• press – to form a matrix imprint on the product;
• wave – for producing wave-like elements from metal rods.

Making the “Snail” machine

Using the list of tools and metal parts below, you can assemble a solid snail machine.

To work you will need:

• metal rods;
• steel sheets and strips;
• profile steel pipe;
• welding, pliers, grinder.

Drawings and step by step diagram, as well as watching a thematic video, will allow you to get a high-quality device with the necessary parameters:

• Using a piece of paper, draw on it an image of a spiral with three turns. Next, check the dimensions so that a reinforced rod with a diameter of 10 mm fits into the thread;
• Using a grinder, cut two plates from a steel sheet. The first should have parameters of 100x100 mm, the second - 130x130 mm;
• Take a 3 cm rod and three steel strips. The cut edges of all used parts must be sanded to remove burrs;
• Using pliers, bend the steel strips according to the template, as a result you will have three spiral parts with different lengths;
• Using welding, all elements of the machine are welded according to the diagram, welding work It is recommended to carry out it qualitatively, since the service life of the tool will depend on them;
• The steel pipe is welded last from the bottom in the center of the machine.

As a result of the work carried out, equipment for cold forging of metal should be obtained, as in the photo.

If, when decorating any interior elements with cutting profile pipes no one experiences difficulties, then if it is necessary to bend them, on the contrary, everything becomes more complicated.

A special specialist will allow you to carry out such work efficiently and quickly bending machines for pipes that you can make yourself in advance.

Different drawings for the manufacture of this type of equipment can be used, depending on what materials will be used in the work.

At first glance, assembling a production-type machine for cold forging of metal, as in the photo, is difficult.

But if a master has already gained experience working with metal, nothing is impossible for him. The main thing is to choose a solid, stable foundation for the future structure.

For example, it could be a massive metal table made from pipes or profiles.

Since bending of the metal will occur due to the shafts present in the structure, it is necessary to select three such elements.

Each of them is a metal cylinder with thick walls and an axis of rotation. Two cylinders are fixed slightly above the table, and the third, central, is placed above them.

The distance of the two outer cylinders determines the angle at which the pipe will be bent.

In order to be able to change the position of the cylinders if necessary, it is necessary to make additions to the design drawings in the form of stoppers and rollers, which will make this part adjustable.

After the cylinders are fixed, it is necessary to organize a rotation transmission system for them.

For this purpose, they use a chain mechanism from an old car, which can be found on the spare parts market.

It is better if the mechanism is equipped with gears; if not, then they will have to be purchased separately.

The gears are mounted on the two outer cylinders and the tensioner is placed below the shafts in the center. Then one of the outer cylinders is equipped with a handle in order to create a rotating force.

The machine for cold forging of metal products is ready. The following video will help supplement the above material with details.

How to make a torsion bar machine

A machine for cold forging of torsion bar type products is used for twisting metal spirals in the form of a snake.

It is difficult to work with such a device manually, therefore, most often for the manufacture of a torsion bar, drawings with electrical versions of machines are used.

In order to properly assemble the torsion bar, we suggest watching the video and reading the instructions below.

Tools and materials for assembling the machine:

• steel sheet;
• I-beam;
• vices and fasteners;
• gearbox, electric motor, chain;
• Bulgarian;
• welding.

Action sequence diagram:

• The basis will be an I-beam, to one side of which a steel sheet must be welded;
• Then a vice is attached to the steel, welded and secured with bolts and nuts;
• So that when tension metal product does not jump out of the machine, plates are attached to the vice from below and above;
• The other side of the I-beam is equipped with rollers, on which the platform is subsequently mounted;
• Another vice with movable main elements is attached to the surface of the resulting structure. In this case, both structures located along the edges of the I-beam will have to be located on the same level;
• Next, the structure is equipped with a steel handle made of rod; due to its rotation, the product will be bent;
• Using bolts, connect the reduction gearbox and the engine. The steering wheel rim is equipped with a chain;
• The structure is covered with a steel casing.

As a result of these actions, a machine with two blocks is obtained - movable and stationary.

“Snail” equipment for cold forging – mandatory hand tool any craftsman who produces forged products without heating the metal. The “snail” is designed to bend a metal rod during cold forging of metal. Making a “Snail” for cold forging with your own hands is not so difficult.

Using homemade cold forging machines, you can make many openwork metal products. Forged fences, fences, gates, gates, railings, benches amaze with their interesting shapes and rounded smooth lines. It is the curved shapes of forged products that are made using a “snail” - a machine for cold forging of metal.

The production of snail equipment takes place in several stages.

In the next video you can see how a craftsman made a homemade “snail” with his own hands, as well as how and what kind of blanks can be made using such equipment for cold forging.

This video shows another interesting view a homemade “snail” on which it is convenient to bend forgings into curls and volutes. According to the master, “everything is made more convenient and easier on this machine.”

The following video contains a drawing and description of the snail device and necessary materials for the manufacture of a bed and patterns for the production of forged curls.
