Do-it-yourself miniature machine from an engine from a washing machine
But as for the engine from the washing machine, this is perhaps one of the best motor options for assembling a circular saw at home. Washing machine motors have a long service life and endurance. Low shaft revolutions are fully compensated by the design – in most washing machine engines there is a groove for the pulley key, and the body itself has convenient mounting holes. You can increase the number of revolutions of the saw blade by installing pulleys of different sizes on the motor and the working shaft, or take an electric motor from the centrifuge of the same washing machine. By the way, a machine with a direct drive can be made from a centrifuge motor, such a motor usually has a long shaft, and a small-diameter saw can be installed directly on it. \
But the main advantage of the washing machine engine is its power. It is designed for a long period of work, and for a circular saw this is the most important thing..

It was no coincidence that the frame was made of a shaped tube. The design uses a profile of 20×20 mm and 25×25 mm.
This frame is strong and stable. The side racks are made the same. They are connected at the bottom with a 25×25 profile, and at the top there is a jumper made of a pipe with a section of 20×20 mm. The resulting frame of the table circular is raised above the surface on plastic legs, this increased the stability of the instrument. Bolts for fastening the engine are installed on the lower jumpers.
The working shaft attachment is made of a nut. The inner thread of the nut is ground down, the diameter corresponds to the outer diameter of the shaft bearings. To fix the bearings, a retaining ring will be used, under which a groove is made.
Assembly
The assembly of the circular saw begins with the installation of the motor on the frame.
After installing the engine, put on the belt.
After tensioning the belt and setting the position of the engine, it is fixed with nuts.
To protect the motor from sawdust, protective screens are installed on the housing.
The circular saw is installed and clamped on the working shaft.
For the convenience of switching on, a switch is installed. The last step is to install the circular desktop.
As a test, various materials were cut: boards made of wood chips, a piece of chipboard, boards with a thickness of 30 mm.
As you can see, the result is impressive.
Making a circular saw with your own hands
The need to have a small circular machine on hand has probably occurred to everyone who at least once tried to make a straight cut with a jigsaw or a hand saw of a small plank or strip of laminate. It’s another matter when such an operation is performed on a stable machine. Even if this circular was assembled from metal with its own hands and does not look very presentable, this wood machine allows you to do the job faster and better. That’s just how to assemble the circular yourself at the lowest cost and use the available parts, for example, the engine from the washing machine?
Table top
A sheet of metal with a thickness of 2 mm will be used as the tabletop of the working table in the circular. This is enough for the workpiece to move freely on the work table..
Holes are made in the metal for mounting countersunk head screws. In addition to metal, chipboard can also be used as a table, and made from plywood. It is recommended to make the working table of the circular so that it is possible to install an emphasis on it.
Rotation transmission
This table saw will use a belt drive. From the motor pulley, rotation will be transmitted to the drive shaft using a V-belt. The pulleys on the machine are used of the same diameter, so the rotation speed of the working shaft will be the same as that of the engine – 1450 rpm. These are the standard pulleys used in a washing machine..
The circular shaft is taken from an angle grinder. This decision is fully justified. There is no need to be smart with turning work, there is already a ready-made thread with washers of the required bore diameter. And you can adjust the diameter of the shaft with your own hands, simply by holding the shaft in a drill and processing it with a file.
A working shaft with a pulley installed on the frame will look like this.
From a drill
This is not the best option for a miniature circular saw in terms of durability and reliability. If you use a hand drill without making additional design changes, then you can offer two options for a circular saw from a drill. The first option will use a chuck, without any changes – the disc blade will need to be pushed onto the bolt and clamped in the drill chuck. The second option would be to remove the drill chuck and use the spindle to secure the saw. But be that as it may, a hand drill is intended for short-term operation, manufacturers recommend using it continuously for only 2-3 minutes, after which a break should be made for at least 5-7 minutes. This tool is designed to work with drills with a maximum diameter of 10-13 mm, so it would hardly be reasonable to use a circular saw blade with a diameter of even 125 mm on such a saw..
Manual circular design
A manual circular can be easily done by hand if an angle grinder is available. You will need to make the following simple tools: slide stop and axle handle.
- Metal corner.
- Washers.
- Bolts.
- Nuts.
- Metal strip.
- Angle Grinder.
- Metal pipe or rod.
Tabletop small circular
The hand-held circular can be easily converted into a small tabletop design.
To do this, you need to make a U-shaped bed from a pipe or rod of 15-20 mm and attach a lever. The lower part of the bed must be bent along the cutting direction to horizontal, and then fixed to the table with self-tapping screws. To make the structure stable, you can additionally install slopes.
On the horizontal cross member, you will need to put on a rotating lever from a T-shaped pipe.
Circular saw performance check circuit.
The transverse part of the element will need to be cut into two parts. After the structure is installed, the elements will need to be fastened with clamps. To the end of the vertical part with a clamp, you need to tighten the hand saw that was made.
A similar design can be used as a cutting device, for which you need to install a standard cut-off wheel in an angle grinder. However, in this case, the thickness of the cut will not exceed 70-80 mm, everything will depend on the diameter of the working element. To be able to process thick lumber, you need a full-fledged circular saw.
Making a stop and preparing the necessary holes
Circular saw T-stop diagram.
The slide stop is made from several pieces of a small metal corner, which are located on either side of the working element. It should be noted that the working element is a disc with teeth, which is used instead of an abrasive wheel. The gap on each side should be approximately 3-4 mm. The horizontal edges of the corners will need to be rounded at the bottom so that they do not cling to the workpiece being cut. The corners will need to be cross-linked at the front and back. For this, it is best to use bolts with nuts, a gap can be made using a package of washers.
You will need to put on a clamp made of a metal strip on the tool body. The clamping screw of the clamp should be located at the bottom of the structure. You will need to firmly secure a double-folded strip of sheet metal or galvanized steel with a hole for the rear stop bolt for sliding. The stop must be fixed at the rear of the structure. The clamp with the back stop can be a single structure, however, the thickness of the metal strip in this case should be approximately 1-1.5 mm. By moving the washers that provide the gap, you can achieve the same gaps between the working element and the side parts of the stop.
Assembly diagram of a homemade sawmill.
In the gearbox housing of the tool, you will need to drill 2-4 threaded holes for small fasteners. The first step is to disassemble the gearbox and identify the places where it is possible to drill. The holes are designed to be able to fix the homemade axle handle. If a standard side handle of an angle grinder is used, then making an even cut will be quite difficult even for a master with extensive experience..
How can you make a circular with your own hands?
Today, you can often find homemade circular saws. A do-it-yourself circular can be made if the master has at least minimal skills in working with metal. For the manufacture of the structure, you will also need some fixtures. All work must be done carefully.
Figure 1. Schematic of a stationary circular saw.
It is advisable to make such a device yourself if any of the following materials are available: pieces of an angle made of steel, a rectangular shaped tube, an engine or an angle grinder. If there is no motor, it can be purchased on the construction market..
Making a handle and adjusting bar
The axial handle is made from a pipe or rod in the form of a horn, which is directed upwards. In this case, a cross brace with a small width can also be used. The ends with which it will be fixed to the gearbox do not need to be splashed. In these parts, you will need to drill holes for fasteners. If the mounting ends splash, the handle will bend from the effort during operation..
If the handle looks like a horn, then the far part of it must be splashed in a horizontal plane and a hole must be drilled in it for an axis of 4-5 mm with a margin. If the handle is a bracket, then in the holes that are located in the gearbox, you will need to install a piece of a rod or tube sticking out forward. The end of the element must be splashed and a hole drilled in it. There should be a small distance between the rod and the bracket – approximately 100 mm.

Next, you need to take a piece of a 4-5 mm steel rod, which will be used as an adjusting rod. One part of it must be bent in the form of a loop, slightly splashed and drilled a hole for the front stop bolt. Substituting washers on the front of the stop, you need to achieve a uniform slot width along the entire length of the structure. If a 6 mm rod is used, then you will need to prepare several washers of small thickness.
The back of the rod needs to be threaded. The element will fit into the hole in the handle. One nut must first be screwed onto it, and after the assembly is complete, the second. You will need to loosen and tighten the nuts in turn so that you can adjust the cutting depth. At this stage, the manual circular will be ready for use..
Complete stationary circular
It is possible to make circulars of this type only if you have a design diagram. The difference between a stationary and table circular is the height of the bed. A diagram of a structure of this type is shown in Fig. one.
The first piece to make is the table. It is covered with tin or galvanized sheet. The wood will rub against wood or plastic, resulting in a small hole. In this case, it will not be possible to make a high-quality cut. Transverse table joints are made of 70-80 mm metal corner.
The working element should not protrude more than 1/3 of the diameter above the table base – otherwise the saw will be dangerous. Therefore, if it is necessary to cut a 100 mm beam, then the disc diameter must be 350 mm or more. To drive such a disk, a motor with a power of 1 kW or more is required..
The first step is to compare the power of the purchased engine with personal needs. For blanks of 150 mm and more, it is quite difficult to make a circular yourself.
A high-quality adjustable stop can be made from a piece of 70-80 mm corner, its length should be 350-400 mm longer than the table length. One of the shelves will need to be cut on both sides so that the remainder is equal to the length of the table. The backs need to be bent down. In the lower shelves, you will need to drill holes for the thread of the fasteners. After that, you will need to put a stop on the table and fix it in the required position with bolts. The stop is set according to a template that is laid between it and the tool disc.
The most critical unit is the shaft. It is recommended to use a ready-made element with a seat for the disc. It can be purchased in the construction market.
You will need to use self-installed ball bearings. Trunnions with bearings should be with covers that can protect against sawdust.
It is recommended to use a V-belt drive. The engine will fit from an old washing machine. Capacitors can be paper or oil paper. Other elements will not be able to withstand the reactive power that circulates in the chain.
It is quite easy to make a circular yourself if you know the technology and have all the necessary elements in stock.
Circular made of angle grinder, hand-held circular saw, drill
Many do not have the opportunity to assemble a homemade circular with a powerful electric motor, belt drive and pulley system. But surely there is at least one of such power tools as a hand-held circular saw, an angle grinder or a drill. On any of them you can attach a circular saw, they are compact and can be used as an electric drive for cutting not very thick boards. As noted above, these tools are best attached to the table top from the bottom. The most convenient in this regard is a hand-held circular saw, because it has the maximum size of the useful part of the cutting disc, while the case of a drill and an angle grinder does not allow using the entire saw area. Plus, the thickness of the lid covers part of the disc. Therefore, you can put a saw with a larger diameter or apply other technical solutions. The figure shows a possible method of attaching the power tool to the bed using plastic clamps..
Circular saw table
The circular table must be stable. Swaying during operation is very disturbing and can be dangerous. An old kitchen table or a prefabricated structure made of wooden bars or a metal profile is suitable as a frame. An important part of the bed is a flat, wide surface with a slot for the saw blade. It is made from an iron sheet of at least 4 mm, fiberglass plate, plexiglass, plywood, chipboard or a combination thereof. In any case, the thickness of the table top must correspond to the load that it will endure during operation. It should be borne in mind that the drive in some homemade circulars is attached precisely to the lid, so it is better to make it lifting, as shown in the photo. This avoids the complexity of the bed structure and facilitates access to the power tool..
A guide bar is usually made from a corner, which is attached to the slab with clamps each time a new size is set. You can make a sliding bar, as seen in the picture. In this case, the table top must have strictly parallel sides for sliding, and the guide bar is perpendicular to the plane of rotation of the circular saw. This is very convenient, but it requires a little work. Sliding sleds are made from a steel or aluminum corner, which should slide freely around the edges without losing the right angle. Option with wooden skids is possible, but this makes the machine bed more bulky and less durable.
DIY circular saw
A homemade circular saw is one of the most essential machines for a home craftsman, especially when building a house or summer cottage. Branded stationary machines are very expensive, and for most household needs, a homemade, simple design of woodworking equipment will do. There are many ways – how to make a circular with your own hands from a hand-held circular saw, an angle grinder, an old electric motor, and even from a drill. What is needed for this and how to assemble a circular saw table with minimal costs is described below.
Pendulum circular with a powerful electric motor
A homemade circular saw is designed to cut wood of the thickness for which the electric drive is designed. If it is necessary to process thick blocks, you will have to install a powerful electric motor, mount a belt drive and a shaft. In this case, it is advisable to make a pendulum bed, as shown in the figure. The frame is completely stationary, welded from steel corners. The entire twisting and cutting mechanism is located on it. One side of the frame is suspended from the bed, and the other side is adjustable in height using a screw mechanism. Such a scheme allows you to adjust the height of the saw blade departure without much effort and unnecessary design difficulties..
Structural elements of a DIY wood sawing machine
To make a stationary machine for sawing materials at home, you first need to know what structural elements it consists of. Whether it’s a do-it-yourself machine made from a hand circular, an angle grinder or a tool assembled from disparate elements – the set of basic parts is the same.
The surface of the table must be made even, for a better product at the exit
The main elements of stationary circular installations are:
- Table for connecting and fixing mechanisms. If the circular is powerful and massive, it is better to use a metal table. Options from chipboard, wood, plywood are suitable, as long as the surface is smooth.
- Shaft. The most important detail. When making it, they use a lathe separately. The dimensions should be calculated accurately, this will avoid beating.
- Casing. This element ensures safe use of the circular saw..
- Engine. When using an angle grinder or circular saw, it is part of the power tool.
Helpful advice! If the design is supposed to be prefabricated, then when creating a circular with your own hands, an engine from a washing machine will be the most successful option..
In the design of the circular, there must be moving parts of the drives, and a button must be installed in the power supply circuit to stop the engine in emergency situations.
Circulars of any fixed type consist of main parts
Features of assembling a circular with your own hands from an angle grinder
A circular saw is not found in every home workshop, but almost any owner has an angle grinder who performs certain household tasks with his own hands. To create a stationary saw installation, you will also need a workbench or a special table, the tool will be attached from below, like a circular saw.
Attachment to the angle grinder is done using bolts
But then the assembly process is somewhat more complicated. To make a circular grinder out of an angle grinder with your own hands, as practice shows, it is necessary to think carefully about the option of attaching a hand tool to the bed. It could be the following way:
- A metal band clamp is pulled onto the angle grinder, the tie of which should be at the bottom.
- Double-folded metal strip attaches to sliding stop holes.
- Holes are made in the gearbox of the power tool. The body is pre-disassembled, the drilling sites are outlined.
- With the help of the holes made, an additionally made axial handle is attached.
The handle can be made from a metal tube or rod. The workpiece needs to be shaped like a staple. In those places with which it will be attached to the gearbox, it is also necessary to make holes. A big and serious help for making a circular from an angle grinder with your own hands – drawings. They will allow you to correctly calculate the size and number of elements, to prevent mistakes when calculating the attachment points. If it is difficult to complete the diagram of the future unit on your own, you can use the ready-made drawings offered on the Internet.

Possible options for small, hand-made circular saws
Any stationary circular, even a homemade one, requires a fairly spacious workshop. The space should allow not only to install the unit itself, but also to place the workpieces intended for cutting in the desired position. If the task is not to dissolve large wood, but simply, if necessary, you need to independently make a rail or a bar for repairing furniture, etc., it will be more rational to get a desktop circular mini-saw.
Such a device can be done by hand, using the same principles as when creating stationary machines from an angle grinder or circular saw. Only the stand will not be the goats, the support of which is the floor, but the bed, on which a small table is installed with a fixed hand tool.
Helpful advice! When making a circular of this type, it is important to take into account the overall height of the structure, that is, the plane on which the material intended for sawing will be located. Overestimation or understatement of the level will cause significant inconvenience.
The miniature machine is more functional and safer to use
If you need to create a circular mini-saw with your own hands for making workpieces of very small sizes (aircraft, ship modeling), you can assemble a tool using a PVC pipe as a body and borrowing an engine from children’s toys. In such a pipe, it is easy to make a hole for the shaft. A glue gun can be used as a joint material. Such a circular can be powered both from the mains and from a battery. To ensure autonomy of work, it is necessary to provide a special compartment for batteries in the case..
Which discs should be used for circular
The performance and quality of work to a large extent depends on a properly selected disc for a do-it-yourself circular from an angle grinder, hand saw or assembled from separate mechanisms. It should be remembered that discs are different for wood and metal. Even if thin, soft aluminum is to be cut, the blade must be fitted appropriately. Cutting wheels have smaller teeth. There are universal disc options that are applicable to work with both wood and metal.
There are differences and discs designed for longitudinal and cross-cutting wood. Rip sawing is carried out with a cutting attachment with large sparse teeth. But transverse cutting will be of better quality in the case of using discs with fine, frequent teeth..
As for the material and method of manufacturing discs, they can be monolithic and carbide. Monolithic are made from a single piece of high-carbon steel. Such nozzles are inexpensive, but at the same time they have a significant drawback: they quickly become dull and need sharpening and wiring..
Circular discs can be for wood and metal
Tungsten carbide wheels are made from cobalt and tungsten soldered tool steel. They are more durable, but the price for such products is much higher..
The outer diameter of the discs for a homemade circular is limited by the size of the protective casing. The standard disc thickness is 3.2 mm. There are thinner and thicker saw blades. Thin ones are used when working with valuable wood species to make a clean cut. For coarser work, thicker discs are recommended..
Diy circular table (with drawings)
This section offers a model of a universal table, on which you can place a circular having any technical characteristics and dimensions. For the manufacture of the structure, you will need the following materials:
- plywood sheet, preferably with a laminated topcoat, at least 10 mm thick and 800×800 mm in size;
- 4 sheets of laminated chipboard 16 mm thick (400×784 mm);
- bars 50×50 mm;
- bolts and screws.
To make a homemade circular saw and table, you will need blueprints
How to build a Drill Press(Drill Guide) Machine | Handmade Drill stand
The manufacture of a circular table can be performed in the following sequence:
- The upper part of the future table is assembled from laminated chipboard sheets, which is a box without a bottom. The sides are attached to each other using bars, the length of which is much greater than the height of the sheets.
- The manufactured structure is turned over, the bars-legs of the future table in the lower part are fastened with additional jumpers.
- A tabletop is cut out of plywood, in which a longitudinal hole is made using a jigsaw – a saw blade will be inserted into it.
On the Internet, it is easy to find a drawing of a similar design, which will greatly simplify the manufacture. You can modernize the above version of the circular table with your own hands by replacing the bars with a metal corner or by making a so-called box made of boards. It is nice to make a shelf at the bottom of the structure..
Scope of application of a homemade circular saw
In the process of building a new home, when wood material is used in large quantities, a homemade circular will not be enough. And the functionality of such a device will require a wider one. But when performing repairs, a home circular machine becomes an indispensable technical assistant..
A hand-made circular saw allows safe work and accelerates the construction process
Quite often, the dimensions of wooden elements are determined directly in the course of work. The ability to independently provide the process with the necessary materials saves time and money to a large extent. And often the quality of wooden blanks is guaranteed to be higher.
On a homemade circular, you can dissolve the boards into bars, make planks, slats, rip off workpieces, cut boards of wood materials into fragments of the required size.
Using a homemade circular, you can make such types of furniture as a table, shelf, rack. A similar stationary home tool is applicable when creating wooden sports equipment, making containers, etc..
When installed on a saw blade with certain technical characteristics, the mechanism can be used as a circular for metal. It is allowed to saw soft aluminum and sheets of other types of metal, the thickness of which does not exceed 2 mm. When working with thicker material, the mechanism will overheat, provoking an automatic shutdown..
For cutting firewood and simply cutting pieces of wood, a firmly fixed table with a saw slot is enough
Stationary circular do-it-yourself from a manual circular
The operational capabilities of a hand-held circular saw are significantly increased if it is converted into a stationary tool. To understand how to make a stationary circular from a manual circular, you should first understand the methods of rigidly attaching a power tool.
As a stand, you can use trestles made of metal or wood. It can be either one or two products (if the dimensions are small), interconnected by boards with a thickness of at least 50 mm or bars with a similar section. Next, you need to attach a tabletop to the top of the stand, which will act as a bed.
For these purposes, it is convenient to use thick plywood (at least 10-12 mm) or two sheets of thinner material joined together, which together will give the same thickness. Chipboard blades or metal are also suitable. If the metal is thin, it is better to attach it to a wooden base..
Install the hand saw from below. Preliminarily, a saw is made in the tabletop, necessary for extending the disc.
You need to attach a tabletop to the top of the stand, which will act as a bed
Important! It is necessary to fix the tool so that the saw blade is located strictly parallel to the cutting line, that is, at the same distance from the sides. Otherwise, it will not be possible to correctly install additional devices and achieve high-quality sawing..
Using the above technical methods, you can make a circular saw from an angle grinder. But this hand-held power tool has certain differences, therefore, a slightly different assembly scheme will be required..

Completion of the circular
Figure 3. Connection diagram of parts of a homemade circular saw from a drill.
For more accurate and correct operation of a homemade machine tool, many owners are modifying it. A metal guide from the corner can be installed on the working table of the machine. Holes are drilled in it, through which the corner is screwed to the table and limits the width of the sawn-off part of the workpiece. Thanks to this device, you can cut many strips of exactly the same size..
It is possible to adapt the protective cover for the saw blade, draw auxiliary mowing lines on the table to roughly determine the size of the material to be cut.
When working on a homemade mini-machine, certain rules and safety requirements must be observed:
The device of a small-sized circular saw based on an electric drill.
- Free the place of work from unnecessary materials, things and tools.
- Feed the workpiece to the saw blade smoothly, trying not to skew it, so as not to jam the blade.
- Before stopping the machine, the workpiece must be brought out of contact with the disc..
- Keep the mini circular clean and tidy.
- Remove the drive (drill) if the circular is not needed.
This machine allows you to cut not only wood. Instead of a saw blade, various cutters can be used. This makes it possible to process workpieces made of brass, aluminum, other soft metals, plastic, polypropylene. This is a valuable asset for aircraft and ship modelers. Before work, it is a good idea to check all components and mechanisms for beats. To do this, you need to briefly turn on the drill several times and observe the behavior of the disk. If there are beats, you need to eliminate them with washers, if there are no beats, you can start working.
What is a circular from a drill?
In a home workshop, a situation often arises when you need to saw a piece of wood lengthwise into separate bars. To do this, you need a circular, which not every master has. You can perform this operation with a hand saw, but it is a very difficult job. It is especially difficult to accomplish this task when there must be several cuts, and the material is very strong. There is no point in acquiring a factory-made circular installation for these purposes. But you can make a small machine for cutting such strips. It is especially needed for those whose hobbies are related to modeling..
Image 1. To make a circular saw from a drill, you need dense plywood or chipboard.
You can make a small circular on the basis of a conventional drill, which will act as a drive. When the machine is not used for its intended purpose, its base is retracted on the shelf, and the drill is used in the usual way.
Circular design
The product design consists of:
- grounds;
- the working surface of the table;
- racks;
- electric drive;
- shaft for saw blade attachment.
Image 2. Layout of a circular drill.
For the manufacture of the base, you can use veneered chipboard furniture board. Its dimensions are 300×250 mm. The thickness can be 20-30 mm. It is better to make a working table from a duralumin blank 4 mm thick. In its middle part, it is necessary to cut a groove for a saw blade with dimensions of 160×10 mm. Instead of a duralumin blank, you can use a piece of sheet steel. In this case, the weight of the finished product will be slightly higher. In an extreme case, multilayer plywood or chipboard is used, but this material has a much lower strength and allows processing of material of lesser thickness (image 1). In more detail, all the details can be viewed on the layout diagram of the machine (image 2).
The functions of the drive are performed by an electric drill, which must be firmly fixed. Drill holders can be made from wood and metal. They can look like legs with clamps, like staples that wrap around the gearbox housing of a drill. The shaft holder can also be manufactured in a similar manner. All parts are connected to the base and the work table by means of rivets, fastening nuts and countersunk bolts (image 3).
The drill and the drive shaft can be mounted in a holder made of board, chipboard. It is placed sideways, a recess is made according to the dimensions of the drill and the tool is clamped using an additional pressure bar and bolts.
Tool making and operating tips
For the circular to work properly, follow the recommendations:
Electric Drill Power Tool Options.
- On the basis of a drill, you can build a multifunctional home circular machine that can perform the functions of a lathe, cut-off, grinder, sharpener and circular.
- On the machine, you can select the grooves in the workpieces if you replace the saw blade with a flat milling cutter.
- Mini circular can be used as a cut-off machine in the manufacture of frames.
- It is desirable to make the desktop metal. If it is wooden, you need to cover it with a sheet of metal..
- The saw blade should rise above the table by a maximum of one third of its diameter..
- For the manufacture of a side stop, it is better to use pieces of steel angle 60×80 mm.
- Self-aligning ball bearings are recommended.
A very simple and practical machine can be made using an electric drill as a drive.
It is capable of processing wood, plastic, hardboard blanks, cutting them into thin plates and strips. It can be used for polishing small items, sharpening drills and cutting tools, milling grooves. It can be used with great success in workshops of schools and art houses. For manufacturing, you need several pieces of chipboard, a piece of sheet metal, bolts and nuts.
In the future, if a special need arises, you can modify the machine to a more serious version. But as a drive, you need to prepare a more powerful electric motor and install it on a special platform. Such a unit can be made from pieces of steel angle, rectangular pipe.
