The vast majority of repairs and dacha work require a good carpentry power tool. Often in home carpentry it is required to dissolve massive lumber into a rail or planks. You don’t run into a stationary circular to your neighbors, and a hand-held circular saw is inconvenient for these purposes. Therefore, most DIYers sooner or later come to the idea of making a stationary circular saw for themselves with their own hands from improvised materials.
Working conditions of a circular saw for wood
A circular saw is necessary, first of all, in order to make a long cut in a solid wood, accurate and even, like a stretched string. It is possible to ensure high cut quality only by fulfilling three conditions:
- High speed of the cutting edge of the saw. Ideally, you can get a cut quality comparable to a surface ground with emery cloth;
- Sharp cutting edge of a circular saw tooth. Some brands of discs are made from high speed steel, but it is best to use a carbide-tipped tool;
- High rigidity of the "circular saw blade - desktop" system. The higher the rigidity, the more accurate and smoother the cut line will be.
Any saw with a working tool in the form of a toothed disk poses a serious danger to the worker, so they try to make the table for a circular saw with their own hands as durable and convenient as possible.
For your information! In industrial circular saws, large-diameter discs are used, up to 60-70 cm, so the motor speed is relatively small - 800-1200 rpm. In a home circular, the dimensions of the cutting disc do not exceed 25 cm, so the rotation speed is required quite high - up to 10,000 rpm.
Circular manufacturing options
You can build a circular saw in a home workshop according to one of four schemes:
- Install an asynchronous electric motor of 1.0-1.5 kW on a table welded from metal, make an increase belt drive on the shaft, on which, using a flange, fix the cutting disc;
- Make a small wooden table for a low-power engine from a washing machine;
- Install an industrial hand-held circular saw on a machine assembled from a wooden beam;
- Use an ordinary angle grinder as a drive for building a circular, in which the abrasive disc is replaced with a steel cutting tool.
All these schemes are used in practice with different efficiency. If you want to dissolve thick, up to 100 mm thick beams and logs, then you need a circular saw with a powerful engine and a steel frame.
An angle grinder is well suited for trimming small parts made of wood, but it is practically not used for a stationary circular saw due to the limited time of continuous operation. A relatively weak and uncomfortable circular saw is obtained from the engine from the washing machine. Low power - 500 W and low speeds require the manufacture of a step-up V-belt drive and a system of two shafts. There is a lot of trouble, and the quality of the cut and the productivity on such a circular are low.
Building a home circular
According to the reviews of many home-made carpenters, the easiest way is to convert a manual circular saw model into a stationary one, or, more correctly, an easel one. In this case, you can kill at least three birds with one stone:
- Firstly, hand-held circular saws have high rotational speeds, which means that a good cut quality is ensured;
- Secondly, in a commutator motor, the shaft is mounted on bearings designed for radial load;
- Thirdly, the cantilever mount of the cutting disc allows you to relatively quickly replace it with a new one, without disassembling the circular saw.
For your information! The main advantage of the above circular saw circuit is the well-chosen engine torque and its speed, which ensure maximum machine performance.
On a 225 mm disc, the overhang or height of the disc above the work table is only 40 mm. This is more than enough to cut a forty board into a plank or rail, cut out any curly details and solid wood. In addition, a spring-loaded protective cover is installed on the body of the circular, covering the cutting edge in the non-working position.
Perhaps this device is useful and necessary to protect fingers and hands, but it only interferes with work, since the thin cutting edge of the disk is not visible. Therefore, when reworking, it is often dismantled or fixed on the body of the circular saw in the open position.
Converting a hand-held circular saw into a stationary version
All that needs to be done to convert a hand saw to a stationary version of a circular saw is to make a table or a box-shaped case and fix the saw on the reverse side of the table top so that part of the cutting edge of the disk protrudes above the plane of the table, photo.
The size and shape of the table for the circular is chosen based on the width and length of the lumber. For small boards, a one and a half meter table, 60-70 cm wide, will be optimal. The supporting part of a circular saw can be welded from a steel corner with a shelf width of 25-30 mm. In the upper and lower parts of the legs, horizontal spacers are welded from reinforcement or a corner. This solution allows for maximum rigidity of the frame.
For countertops, you can use laminated chipboard or OSB, plywood 15-20 mm thick. At the same time, the countertop itself does not have to be placed symmetrically with respect to the steel support frame. When cutting a board on a circular saw, you have to work with two hands. With one hand, the material is longitudinally fed forward, and with the other we press the board to the table. So, the main thing is that the location of the motor and the pressure point are not very close to the edge and do not create a tipping moment for the entire structure.
The plane adjacent to the cutting tool can be covered with metal or plastic to make it easier to move the solid board on the table of the circular saw.
The only drawback of such a remake is the need to remake the controls: the start button and the hold lever. Most hand-held circular saws, in addition to the start button, are equipped with a lever or hold trigger. While you press the trigger to the saw handle with your fingers, the engine of the device is operating in normal mode. It is worth releasing the trigger, as the engine stops. A very necessary thing if, while cutting, you suddenly dropped a working circular saw from your hands.
Therefore, the first step is to make changes to the control system of a hand-held circular saw. To do this, the contacts on the button and the trigger are output to an external electric bag fixed on the body. Of course, such alterations can be performed for power tools for which the warranty period has long expired.
In rare cases, it becomes necessary to remove the tool from the table and use it in its original manual version. In this case, instead of soldering the contacts, the button and the trigger are fixed with a clamp or simply wrapped with electrical tape, and the power cord from the tool is included in the carrying with the on-off button.
The simplest version of the conversion of a circular saw is shown in the photo. For a table circular saw, a case in the form of a box is made of plywood. The tabletop with the installed circular saw is turned over and fixed on the box.
Making a guide line
When working on a circular saw, it is important to be able not only to cut the board, but to cut a plank or rail of a given width exactly to size. To do this, a guide ruler is installed on the saw table, which can be moved relative to the plane of the disk, and thereby select the cutting width.
The ruler is made in the form of a steel corner. With the help of screws, the ruler can be relatively easily moved along the slots in the table top, and thereby change the size of the cut.
A simpler version of the ruler is made from a pine board, 40 mm wide and 20 cm longer than the table size. Along the edges of the board, two furniture nuts with a metric thread are pressed into the lower part. With the help of screws at the ends of the ruler, L-shaped hooks are attached. After installing the ruler, the hooks are tightened with screws, the hooks rise and firmly fix the guide bar on the table top.
Conclusion
Naturally, the capabilities of the commutator motor of a hand-held circular saw are not designed for a serious load. On such a machine, you can cut a couple of dozen strips, after which the engine must cool. The total service life of the motor is 50-70 hours, after which it will be necessary to remove dust, clean the collector from soot and replace the brushes. But, in any case, the possibilities of a circular saw are enough for homework.
For any home craftsman, having their own stationary sawing machine is time saving and safe work.
You can buy a ready-made stationary circular. The cost of small machines starts from 9,000 rubles, more or less decent stationary saws are sold in the price range from 30 to 100 thousand.
Despite the apparent complexity of the design, any craftsman with elementary locksmith skills can make a homemade circular saw. Moreover, during the design process it is possible to add functions that are not provided by the manufacturer.
What is a circular saw for?
Before starting work, it is necessary to determine the main tasks of the sawing machine. If you just need to cut firewood for the winter, or do basic carpentry work like making a fence, a sturdy table with a slot for a saw blade is enough. Such options are popular in rural areas.
Circular for working with logs
Of course, there can be no question of any safety and functionality when using such a device.
In some of these "models" there is a shaft for fixing the knives of a planer or jointer. As a rule, a bed is cooked from a corner or a channel, an electric motor is fixed on it from a decommissioned factory ventilation, and with the help of a pulley, the torque is transmitted to the disk. It makes no sense to describe in detail the manufacturing technology of such a machine.
Another thing is if you want to do carpentry work. In this case, you need a coordinate table with guides that are fixed at different angles.
Since such a stationary saw can work with small workpieces, it is necessary to take care of the safety of the operator. It is desirable to provide for the adjustment of the rotation speed and the possibility of easy change of discs with different diameters.
Be sure to install a protective cover over the disk, and cover the rotating parts of the drive with covers. The starting device is equipped with an emergency switch, and the stop button is placed in an accessible place and is made large.

How to make a circular, keeping a balance between economy, functionality and safety
Consider the main components that make up a home circular saw. You can make them yourself, but with certain skills and tools.
The frame can be made from a metal corner (channel) purchased from scrap metal collectors. If you have the funds, contact the metal rolling warehouse. Legs can be made from old water pipes, connecting them with corners.
A good option for a homemade frame made of rolled metal
IMPORTANT! The use of bolted connections is prohibited, because due to vibration, such a mount will unwind.
Electricity must be used. Be sure to reinforce the corner joints with a jib. The upper part of the frame (on which the table will rest) and the podium for the electric motor are made from a corner with a side of at least 50 mm.
If the machine is equipped with wheels for movement, they must be with steel rims and have locks. The higher the mass of the bed, the more stable the machine will be, and the safer the work will be.
Many beginner craftsmen want to have a small but functional circular saw in their workshop. You can buy a factory-made machine, but it will cost quite a lot. This is the path followed by professional carpenters who have a direct material dependence of their financial condition on labor productivity. Invested funds quickly pay off and bring direct profits.
Amateurs have a good way out of this situation - to make a circular machine on their own with the tools that most craftsmen have. But before starting work, it is recommended to familiarize yourself with the existing engineering solutions and the features of the equipment.
Circular Saw Features
Knowledge of these features is extremely important, you must take into account the operating modes of the saw, know the type of loads and take all possible measures to strengthen the most important nodes. Only with this approach can long-term and safe operation of a home-made machine be achieved.
What are the general features of woodworking mechanisms?
- High speed saw teeth. This ensures the quality of cutting. But high revolutions of the saw blade cause serious injuries, during the manufacture of the machine, great attention must be paid to safety. All devices available on industrial copies must be installed without fail. Do not think that some of them are superfluous, and you can upgrade factory samples for the better. All paragraphs of the safety rules are written in the blood of injured people, do not repeat the tragic mistakes.
- The strength of all knots. This does not mean the ability to withstand significant static loads, although this is very important. The table can easily accept large forces of this kind, but at the same time vibrate from the impact of even relatively minor dynamic multidirectional loads. This condition does not adversely affect safety, but significantly worsens the quality of the cut. On the surface of the lumber, teeth marks are noticeable, it is difficult to maintain the specified linear dimensions, etc.
- Fire and electrical safety. Absolutely all electrical appliances, motors, starters and other special fittings must be installed in strict accordance with the requirements of the PUE. You need to know that dry sawdust not only burns perfectly, but also forms an explosive mixture at a certain concentration in the air. By the way, burning sawdust is difficult to extinguish, they float on the water and continue to burn.
No need to make the simplest machine at the expense of safety devices, strictly follow the recommendations of the designers. Decide what you need, a woodworking machine or fresh problems?

Now you need to get a little familiar with the possible design solutions.
| Type of circular saw | Brief description of technical features and performance characteristics |
|---|---|
| Single-phase motors must be bought in specialized stores; in addition, it is necessary to have a shaft on bearings. This is the most difficult to manufacture and expensive circular saw. If you accurately calculate all the costs, including the cost of materials for the manufacture of the table and the lost time, then it is more economically feasible to buy a ready-made machine for home use. In addition, the complete manufacture of a durable metal saw bed with all adjustment devices at home is impossible; you will have to turn to mechanical trowels for turning and milling some parts. Novice craftsmen are not recommended to use this version of the circular saw. |
| Such solutions are offered by elderly carpenters, they still remember washing machines with powerful engines. In those times, no one saved electrical energy, the power was always installed with a significant margin. Today the situation has changed, low-power economical engines are mounted on washing machines. It makes no sense to make a machine on their basis that is able to saw only plywood a few millimeters thick. |
| A highly undesirable option for several reasons. ● Firstly, the recommended rotation speed of the circular saw shaft is no more than 2-3 thousand rpm. per minute, and the grinder gives 9-11 thousand rpm. The material of manufacture of the teeth, sharpening angles, the amount of divorce and other very important parameters of circular saws are calculated based on this parameter. It is strictly forbidden to use them at such high speeds. ● Secondly, the power of the grinder is about 1kW, which is very small for a stationary circular saw, it will not be able to cut thick boards. And for cutting only one rails, it is not advisable to make a life-threatening stationary machine. |
Conclusion. For a non-professional craftsman, the most optimal option for manufacturing a stationary circular saw should be the use of a portable circular saw as a drive.

There are several very important technical characteristics that make this tool recommended for such purposes.
- On the saw you can install a blade with an outer diameter of 350 mm, which allows you to cut lumber with a thickness of 70–85 mm. On the machine, this depth is slightly reduced, you can cut boards with a thickness of 60–75 mm. This is enough for most homemade wood crafts - from complex furniture to simple toys.
- The engine power is at least 2 kW, it can withstand significant loads, and special effective forced ventilation quickly removes heat, which makes it possible for the mechanisms to work for a long period of time with normal thermal conditions.
- The rotation speed of the saw shaft meets the existing requirements for woodworking cutting tools. This allows you to get excellent cut quality and comply with safety regulations.
- The hand saw can be fixed to the table in such a way that, if necessary, it can be quickly removed and used as usual. At the same time, all initial technical characteristics are fully preserved.
In connection with such advantages of portable saws, we will not consider dubious options for the manufacture of stationary circular machines, but we will focus only on this.

step by stepinstructionmachine tool manufacturing
The technology we offer does not involve the use of complex woodworking machines and equipment, which makes the process much easier for beginners. Before starting, it is recommended to make the simplest fixture in the form of a large wooden square. It is made from a bar 10 × 30 mm and a strip of plywood 10 × 50 mm. It will greatly simplify the process of marking and controlling the correct dimensions of individual parts of the machine.
The table is made from old laminated chipboard, but special moisture-resistant plywood for concrete work is perfect. If you have the opportunity, then buy this material, you will not regret it. It is better to choose foreign manufacturers, but it will cost more.
Step 1. Make a cut of the material for the countertop.
Specific dimensions do not matter much, proceed from the dimensions of the shield and the free space in the workshop. You need to understand that workpieces are better held on a long table, which makes it easier to cut long boards.
To ensure a smooth and perpendicular cut, use the prepared fixture, the rail should rest against the edge of the chipboard, and the saw should slide along the strip of plywood fixed with a clamp.
Our central part of the machine table has a width of 36 cm, two side 18 cm each. Between them, wooden slats made of hardwood will be installed to fasten the cross-cut carriage. Such a carriage greatly simplifies trimming and sawing parts.
Three parts of the tabletop, between which there will be loose slats that move along with the carriage while cutting materials
Step 2 Place the saw on the center of the table and use the awl to trace the outline of the metal platform.
Step 3 Drill holes in the corners of the table, you can do this with an ordinary drill or on a drilling machine.
Step 4 Carefully cut out the opening for the saw with an electric jigsaw.
Using it as a template, draw the liner and cut it out with a jigsaw.

Electric jigsaw
There are options not to make an insert, in which case the maximum depth of cut is reduced. Make a specific decision depending on the planned use of the saw, but practitioners are always advised to rely on the maximum parameters. The fact is that no one can foresee the requirements for the machine in the long term.
Step 5 Attach the saw to the table. Adapt various materials at hand for this, select them according to length and thickness.
Important. Never drive self-tapping screws into chipboard without first drilling a hole. The plate is not designed for such loads and may crack.
Attach the saw to the back of the table.
Step 6 Replace the insert. It is made of a durable material, preferably steel or aluminum, but plastic is also suitable. The liner must withstand the strong shock loads that occur during sawing, chipboard cannot cope with such tasks.
The part is fixed to the sole of the saw, it is necessary to prepare holes and use various hardware.
Step 7 Make markings for the sidewalls of the tabletop, they will be fixed with self-tapping screws. Glue all parts of the table on the transverse bars. On the front side, they are additionally screwed with self-tapping screws with countersunk heads, the holes for them must be countersunk.
Step 8 Check the progress of the wooden slats. If they wedge in some places, then you need to find the cause and eliminate it. The slats should slide freely, but without wobble.
Practical advice. It is much easier to install metal profiles instead of rails. This requires less time, and the quality of the machine is greatly increased.
You can buy profiles at any hardware store, if possible, purchase aluminum elements. They have a small coefficient of friction, and this is very important for the smooth movement of the cross cut carriage.
Step 9 Attach chipboard or plastic boards to the bottom of the table, they prevent the slats from falling out.
Test the performance of the machine. Temporarily set it on a flat surface, plug it in and cut a few boards.
Pay attention immediately to uncharacteristic sounds and vibrations. It is necessary to find out the cause of their appearance and eliminate immediately. At this stage in the manufacture of a stationary circular saw, it is much easier to make adjustments than on a fully assembled mechanism. Everything is normal - continue assembling the equipment.

After you have corrected the problems found during the test, on the saw, make blanks for the side of the table. The dimensions are arbitrary, you can bind them to your actual needs and the parameters of the available materials.
Step 1. Prepare blanks for the sidewalls.
Practical advice. To speed up the process of trimming, attach a temporary device to the saw - attach a small piece of a flat board under the square with self-tapping screws to the rail.
After trimming the workpieces, the temporary fixture is removed, the machine returns to its previous state.
Step 2 Set the table on permanent legs, drill holes and countersink them for countersunk heads of self-tapping screws.
Step 3 At the bottom of the sidewalls, attach boards of the appropriate length. They reinforce the structure and increase the footprint. This increases the stability of the structure, which is very important for a circular machine.
Interesting fact. Have you ever wondered why all the old machines have a cast heavy bed? In those days, the domestic industry could not produce accurate parts for high-speed mechanisms, because of this, beats inevitably appeared during their operation. The heavy frame dampened vibrations - the quality of processing increased. This is us to the fact that the quality of all elements of the circular is of great importance.
Step 4 Test the design again, this time give the maximum load.

It is made from a chipboard shelf 16 mm thick.
Step 1. Drill holes for the skids along the edges, countersink them. The distance between the fasteners is approximately 10 cm.
Step 2 Screw the carriage base to the wooden slats mounted on the tabletop. Check its progress, if there are problems, then sliding wooden surfaces can be smeared with soap or paraffin. Large jamming will have to be sanded with fine emery cloth. Work very carefully, check the progress, do not remove excess material.
Step 3 Screw the two backs, constantly measure the corners, they should all be straight.
Step 4 Cut a hole for the saw. This is done in several stages.
- Install the carriage in the grooves, lift it up, the plane should not touch the saw teeth.
- Turn on the saw and slowly lower the carriage. The hole is sawn until the carriage is lowered to a horizontal position.
- Carefully make a hole along the entire length of the carriage.
- Believe the angle, achieve the correct position. If everything is normal, then it is necessary to additionally fix the back of the carriage.
Step 5 Install the fence parallel to the saw, make sure it works.

A stationary circular saw greatly increases productivity and improves safety. Every novice craftsman should have such a machine; it can be made using a minimum set of tools. We talked about only one option for making a saw, but there are many other equally interesting solutions. How to craft various types of tables for circular saws Can
It is difficult to imagine the workplace of a carpenter or joiner, where there is no stationary circular. Many craftsmen make a circular woodworking machine with their own hands. There are no particular difficulties here, you just need to decide what will be taken as the basis. For yourself, you need to set a goal, and then outline the ways to achieve it. Select suitable devices that will be used in the process of creating future technological equipment for the workshop.
Some specialists use not one, but several machines. Large parts of future pieces of furniture are made on fairly powerful equipment. When assembling, it is sometimes necessary to make additional components. Therefore, small portable machines are used, which are easy to operate away from home.
What can a wood sawing machine be made of?
For the home workshop use:
- Special shafts with fasteners for the disk and electric motors of sufficiently high power. Such equipment can work with large-diameter circular saws, which will allow sawing rather thick workpieces.
- Angle grinders (grinders) produce different capacities for discs of various sizes. The frequency of rotation of the shaft with the tool reaches up to 12-15 thousand rpm. Therefore, the cut quality is very clean. Some craftsmen like to use machines based on angle grinders.
- Hand-held circular saws (RDP) are initially equipped with a wood disc and a fairly convenient casing that can remove chips from the sawing area. Many RDP manufacturers, when developing the operating instructions, attach diagrams of the possible installation of the tool in the countertop. The kit often contains auxiliary fasteners that facilitate such installation.
- A conventional electric drill can also help in creating a small circular machine. It can cut small parts from plywood, boards and chipboard.
- If necessary, sawing large workpieces and even tree trunks is adapted by chain saws. With their help, you can create not just a small machine for sawing boards and bars. A small home sawmill is being made, it will allow you to recycle wood from the garden or the nearest forest.
How to start manufacturing a machine?
Any machine equipment that is supposed to be operated stationary is placed in the table. These tables can be made:
- to full height. The top level of the countertop is placed 75-80 cm from the floor;
- desktop. Small machines mounted on stands or small tables. They are made low (up to 30-40 cm). It is convenient to take such machines with you on a trip; they fit in the trunk of a car or in a trailer.
May be required:
- profile pipes 25 25 (30 30) mm. Using such blanks, rather light frames are obtained, which are then sheathed with boards, laminated plywood or chipboard. Today it is the most technologically advanced material. But welding is required, and experience with a welding machine;
The frame made of profile pipes is characterized by a small mass. The shaft is rigidly mounted on it
- rolled corners 32 32 (40 40, 50 50) mm. The frame is getting heavier. Differs in rather high durability. Sheathe similar metal frames with wood or metal sheets with a thickness of 6 mm or more;
Corner table 50 50 mm. The machine is highly durable
- wooden blocks 40 40 (50 50) mm. For the manufacture of such a frame, there is no need to use welding. All connections are made with self-tapping screws. For greater rigidity, use glue;
Convenient to cut to size
- Chipboard allows you to make simple tables. Assembly is carried out on confirmations or self-tapping screws;
- plywood with a thickness of 15 mm and above is a fairly convenient material for making a table for a future machine. You will need to additionally protect the product from moisture.
Plywood is easy to cut to size. For ease of marking, squares and steel rulers are used.
Circular saws are used for sawing. They are produced in a variety of versions:
- from high speed steel. Such disks are made on stamps. Further sharpening and setting of teeth is carried out. A similar tool is used for rough sawing of workpieces. Most often it is in demand for carpentry with boards;
Stamped circular saw made of R6M5 steel
- with brazed hard alloy plates. Such discs are distinguished by a high culture of performance. After sawing with such a tool, an edge is formed, which is often not processed.
Saw blade with soldered blades made of T5K10, VK-8, VK-10 alloys. Such saws are rigidly attached to the shaft. Beat eliminate
For the manufacture of the machine you will need tools:
- circular hand saw. At the manufacturing stage, guide rails are used, they allow you to perform long and even cuts in the facing material;
- electric jigsaw. With the help of this tool, it is not difficult to make a complex figured cut of workpieces;
- electric is needed for screwing self-tapping screws and confirmations;
- angle grinder is used quite widely. It is equipped with cutting or cleaning discs. Some factories even produce saws for sawing wood;
- a manual screwdriver will be needed to accurately fix individual parts on the machine.
- pliers help to perform complex fasteners;
- a soldering iron is useful for soldering wires, soldering terminals;
- measuring tool: tape measure, caliper, metal rulers and squares;
- pencils and markers will help mark the details on the workpieces.
The result should be a homemade circular machine. It will include a number of basic mechanisms. They will help manage the equipment being created.
Combined sawing and planing machine
For comfortable viewing click on the image
The classic scheme of a home-made woodworking machine assumes the presence of not only a sawing (circular) part. Additionally equipped with a planing table and a shaft. After the completion of sawing, additional processing of lumber is carried out on the jointing part, eliminating existing knots and burrs.
For those wishing to repeat the classic scheme, additional drawings are provided. Using it, you can make a universal woodworking machine.
Creating the first such equipment, you can stop at a less complex model.
The simplest machine equipped with a shaft and an electric motor. Even the engine from the washing machine is adapted for such equipment.
Bulgarian as a saw drive
A positive quality of any angle grinder is a high shaft speed. For most models, it exceeds 12,000 rpm. Therefore, the quality of the cut is quite high.
Adjust the angle grinder in different ways. The options for fixing the tool to the tabletop are shown below.

Manual electric circular saw at the base of the machine
Most modern craftsmen are guided by the creation of a circular saw machine for manual sawing of wood. Attracts the presence of a powerful revving electric motor and ease of installation.
For installation in the countertop, it is enough to fix the tool from below, and then cut the groove. When using plywood, it is easy to make a turntable.
The saw itself is set along the axes so that in the future there will be no difficulties in the manufacture of auxiliary equipment.
Fastening is carried out with countersunk screws or self-tapping screws.
Manufacturing options for such a machine are shown below.
For hand tools, a special case is made. Sawdust will be sent to a strictly designated place
With the help of a plastic clamp, two start buttons are set to the “On” position. A separate switch will be installed on the remote panel
An interesting manufacturing option is shown in the attached video.
Step-by-step process of creating a small circular machine with your own hands
Making a desktop machine from chipboard is quite simple. How to make it yourself is shown in the table.
 | The body is cut from laminated chipboard. Parts are connected using auxiliary rails. Such a connection allows you to get a rigid body. |
 | The cover (table-top) is established from above. It is mounted on self-tapping screws screwed in the corners. Before mounting the countertop, you need to countersink the holes. Then the caps of the screws will not interfere with the work. |
 | On the countertop, a hand-held circular saw is attached from below. To do this, holes are drilled in the support frame. The length of the self-tapping screws is selected so that the sharp fasteners do not come out. |
 | If desired, a stand can be made from below. Then you get a full-size machine. Often such machines are made with collapsible stands. For field work, folding goats are used. |
 | Ball retractable guides are screwed on the side. A carriage is installed on them (a device for parallel movement along the table). After the carriage is made, it will have a cut groove. |
 | For sawing long pieces in a straight line, a parallel stop is used. Most often it is a metal corner, which is installed with a certain gap. When installing such an emphasis, measure the distance from the disk to the corner. It should be the same on both sides. Then the sawn object will not be clamped. |
 | Structurally, a similar element looks as shown in the photo. Fixing in a predetermined position is carried out with nuts. Professionals use wing nuts or special handwheels. They are quite convenient to fix the corner in the desired size. |
 | The disk is installed from below. Modern circular hand saws have adjustable blade offset. It is enough to loosen the stop bolt, and then change the inclination of the tool to the site. |
 | Some craftsmen use a vertical board as a parallel guide. Additional lines are placed here. Then, when performing complex work, it is easier to control sawing according to the specified parameters. |
 | A small circular machine made in a home workshop. It is quite convenient to use it. To remove chips, a hose from a household vacuum cleaner is connected. Then the indoor air remains clean. |
Additional equipment for the machine
To make it more convenient to work on the machine, a number of additional devices are made. They help the master to perform a number of operations. These include:
- guides for longitudinal sawing;
- carriage for transverse movement of workpieces;
- carriage for cutting grooves. Groove joints are used in the manufacture of furniture boxes;
- devices for sawing round parts;
- angle saws. It helps to make furniture legs.
An emphasis for longitudinal sawing.
Having perfectly aligned the saw with one of the edges of the table, I attached it with M4 screws. To do this, I had to drill the iron base of the circular in four places.
In general, any circular is suitable for installation on a table, but if you choose the type of fastening with screws for the base, then it is better to choose a model with an iron base. The cast may crack.
There is another popular way to fix the circular to the table without drilling holes in the base - attach it with clamps that fix the base by pressing it to the surface. Only this method seemed to me not true enough in terms of accuracy and reliability of the installation, and I did not use it.
Another important parameter of a manual circular is the ability to connect a vacuum cleaner. If you saw without a vacuum cleaner, fine wood dust rises into the air.
The disc has been sawn to the top side of the table top. Height - 40mm (Bosh wood disc 160mm). The table top reduces the cutting depth by 9 mm. The depth of cut is set on the circular saw itself. It is convenient that the disk can be completely hidden in the table.
UPD: IMPORTANT! On a number of budget circulars, it may turn out that the disk is under an imperceptible slope. And all cuts will be beveled. Be sure to check with a tool square that the disc is at 90 degrees relative to the table surface. (before installing the saw, you can check the angle relative to the native site. If the disk is not at a right angle and there is no way to set the ideal angle of the site, you can put several strips of tin on one side under the site, achieving the ideal angle (you can use washers for the screws that fasten the saw to the table, but this solution is worse)
Inside the table I placed a socket for the saw, which will now turn on with the start button.
This is how you can connect a vacuum cleaner to the saw. In general, the table is ready and you can saw. (done in one evening and one morning).
Of course, it is possible to cut without equipment using slats and clamps, but it is inconvenient.
This design, clinging to the edges of the table and aligning with them, can move along the saw blade. By pressing the rail against the sled, you can easily cut it exactly at 90 o. Thin pieces of wood can be placed inside the sled.
You can even cut the rail like a sausage :) For example, I cut several pieces of different thicknesses.
Slides solve only part of the problems. For longitudinal sawing, a side stop is also needed.
I glued brackets from plywood that will cling to the edge of the table.
Clings to the edges with a death grip.
The circular saw is a dangerous tool. In order not to saw off my fingers, I made a simple pusher from the waste of a furniture board.
I have already managed to work with this table, sawed and slats, furniture panels, plywood. It became much easier to perform all these works than I did when sawing off with a manual circular saw.
In the future, I will further refine this table:
- I will remake the side stop for longitudinal sawing, so that when moving, it always remains parallel to the disk
- I will put a removable riving knife to which the disc protection will be attached
- I'll make a dust extraction from the top of the table. (Now when I drink, the disc throws wood dust right in my face)
- I will finish the improved pusher. I have already begun to make a more interesting and convenient version of the pusher, I will write about this in the future.
I will gradually implement this in the future, but for now I will work like this.
