Circular ( wooden device) do it yourself
The round wood machine is a stationary equipment with a circular saw blade. In addition to the rip saw, the pendulum saw (cross saw) also falls under the term "circular saw", which is distinguished by the mobility of the saw blade fed onto the fixed lumber.
Circular (woodworking machine): types
Depending on the design of the device, the following types can be distinguished into which the circular tree is divided:
- Table type suitable for home use. Accordingly, a name placed on a table or workbench has an average weight of 25 kg. After completion of work, the machine can be hidden. The maximum straight sawing depth is 75 mm.
- Stationary type. used on average and large-scale production maximum 125 mm. With the help of a stationary circular type, the most accurate and high-quality work is performed.
- Circular machine with stand: it can handle long boards thanks to the inclined support. Folding legs allow you to transport the machine. The maximum cutting depth is 85 mm.
Additional types are selected according to the location of the saw blade:
- Horizontal saw machines. The saw is parallel to the frame.
- Vertical saw machines. The cutting blade is perpendicular to the frame, the saw can be open or semi-open.
- Angle type: two disks working at the same time are located at right angles to each other.
All listed types of equipment can be professional and used for home use. The difference lies in the power of the machines, the number of tools and additional options.
round wood design
Industrial and domestic circular machines are standard equipment. It consists of the following elements:
The main part of the circular machine to which all other pieces of equipment are attached. The frame is usually made of cast iron or strong steel to ensure stability and no vibration during operation, so as not to complicate the process. If the frame is made of wood, it must be secured with stiffeners
- Working surface.
The saw table is a working surface. As a rule, its upper part is made of metal or cast iron, on the surface there are guides and rulers for measuring lumber and ease of installation. The part of the working surface on which the saw blade is located is usually removable, which makes it easy to replace it. The saw slot must match the thickness of the blade, otherwise, with a larger size, the slot will be constantly clogged with chips and sawdust.
The thickness of the processed wood depends on the diameter of the circular saw blade, woodworking machine. The disc must be installed so that it does not exceed 1/3 of its diameter above the work surface.
Professional equipment is usually equipped with a guard to protect the operator from contact with the saw blade, as well as to push the lumber.

Homemade circular saw with your own hands (circular, sawing table)
Homemade circular (sawing or saw machine) can be done do it yourself.
This element serves as a guide for smooth sawing. The longitudinal stop must be made of rigid material and not move during operation, this is fixed in at least two places.
The drive consists of a motor and a shaft on which the saw blade is mounted. High-quality lumber processing requires a two-phase or three-phase motor with a power of 1200-1500 watts. The saw mount shaft must be sized to match the inner diameter of the blade and ensure it is securely and securely fastened.

Do-it-yourself round on wood can be assembled from an ordinary Bulgarian or corner grinding machine. The basis for a homemade machine can also be a hand circular saw or an electric drill. Before assembling a homemade model, you need to think about its design, calculate the load that it will be subjected to.
To begin with, a stable frame or workbench is created. The main ring model does not always require a metal welded structure, since it cannot withstand such loads as a powerful industrial equipment. If during operation the speed of the saw blade does not exceed 4500 rpm, the workbench can be made of wood.
The frame dimensions are calculated on the basis of the main parameters of the equipment, in particular, the dimensions of the saw. At this stage, you need to determine the power of the saw blade. As a general rule, self-made circular wood for own use for home use is made using a saw with a power of no more than 850 watts. But for building a house, it is required to process a much larger volume of lumber, respectively, the power parameters of the saw will be different. In this case, experts do not recommend installing a saw with a power of more than 1250 watts. it will not be justified by being costly and risky in terms of equipment safety.
The frame must provide for the possibility of lowering and raising the disk, as well as the location of the equipment control panel. When placing the control buttons, it is necessary to take into account their safe position relative to the cutting disc. it could be outer side machines or growing table top.
For the production of a work surface, you can use a metal sheet, plywood or chipboard.
An indispensable element of a home-made machine are guides for precise and even sawing of wood. The design of the rails is made of welded steel angle and attached to the table top with clamps. It is undesirable to rigidly fix the guides in order to be able to change their position in the future.
On the underside of the tabletop, the area of the groove for the saw and the fixation of the fasteners are indicated. The legs of the table top are made of a rod, the height of the support is selected individually for convenience. Additional stability of the workplace will be attached to the legs with steel corners and tightening of the supports along the diagonal rails.
The table top can be spaced apart or attached to the table top for easy cutting.
A grinder or a hand-held circular saw is fixed to the bottom of the working table so that the circular saw is directed to the surface through the slot. It is necessary to check the angle of the saw: it should be 90 degrees.
A circular saw is used to cut wood.
Usage hand saw is not always comfortable, the use of the table allows you to make the sawing process more even and accurate
The cutting base has a plane resembling a disk, equipped with an outer edge with teeth. There are models not only of the manual type, but also with the possibility of fixing on the table.
It is difficult to work with large volumes of wood with a conventional circular saw, so it is better to install it on a table
There are several ways to acquire the latter for the convenience of performing manipulations. Table for circular saw you can build it yourself, strictly adhering to a certain scheme.
Table device for circular saw
The table is made taking into account the fact that the hand tool will be installed and fixed on the table, turning into stationary equipment.
construction with my own hands element allows you to make the saw as suitable as possible for individual conditions. Difficulties in the process will not arise if you carefully study the issue. You can customize the product the right size, distribute everything so that it is convenient for you.
Making a table for a circular saw is quite within the power of every craftsman

Scheme for making a table for a circular saw
Before starting work, it is recommended to pass preparatory stage. Be sure to make a drawing. This will make the design process easier. First calculate the dimensions of the table, then transfer the data to paper. The hole made in the structure must exactly match the dimensions of the saw. It all depends on the brand of equipment. Therefore, it is impossible to make a universal hole. The base must be stable and well withstand mechanical loads.
Do-it-yourself circular table drawing
It is unacceptable to hang the structure to one side. The dimensions of the worktop must be suitable for the sawing flow. The final option is determined based on individual desires. Some work comfortably with a folding table or a product with small dimensions.
Drawing of a universal desktop machine
The drawings should take into account important point. If you plan to leave tools or materials on the table during work, then the dimensions of the tabletop must be increased to square meter in the square. Suitable size will be 120 by 120 cm. You should draw carefully and slowly in order to do everything correctly.

Finished tabletop for circular saw
To make a quality construction, you need to follow some tips. The process consists of several steps presented in the table.
| Steps | Description |
| 1 | The bar should be leveled on all sides with a planer. Then the frame of the future table is assembled from it. In each side of the tabletop, you need to drill several holes of 5 mm. Additionally, one through is performed for the legs of the product. |
| 2 | In the drawers, several holes of the same diameter are made. In the legs, one through is performed. The diameter remains the same, 5 mm. |
| 3 | Proceed to install the dowels in the countertop. Before that, they are covered with wood glue. Legs and tsars are placed on top. In the presence of clamps with screeds, the product should be fixed with their help. When the glue is completely dry, you need to fasten the sides and legs using special metal fasteners. Additionally, it should be tightened with self-tapping screws. You can add reliability and strength to the structure by using the corners. They will become an element of additional fastening, give the product stability. For the short side, 2 pieces are enough, and for the long side, 3 will do. |
| 4 | The next step involves fixing the saw to the product with inside. There are several methods to accomplish the task. M4 bolts or bars with self-tapping screws are suitable for fixing. The first case is fast and reliable. The second method does not involve additional holes, which eliminates the need for drilling. It is necessary to make a drink in bars, the width of which is equal to the dimensions of the saw platform. Further, self-tapping screws and bars on both sides fasten the equipment and the countertop |
| 5 | After installing the saw, you will need another larger bar. It, using self-tapping screws, is fixed on the basis of the structure. Screwing is carried out on the marks made when placing the platform in a level position. These manipulations will help, when removing the saw, to return it usually quickly without searching for markings. |
| 6 | The saw blade is set in place. The base is sawn to obtain a longitudinal hole. Then the product must be turned over |
| 7 | Then production starts parallel stop. Two strips are sawn off from plywood. Their length should match the width of the table. On average, these dimensions are 10 cm. Corners should be rounded |
| 8 | The resulting strips are polished. They need to be fastened at an angle with self-tapping screws. A metal corner should be screwed inside |
| 9 | If you need to fix the stop on the base and the structure will be used often, you should attach the guide so that it is perpendicular to the disk. Attach the roller on the bottom. This will allow him to move. |

Video: Circular table made from improvised materials
A circular saw is an important and necessary tool for many people, allowing them to independently engage in numerous types of housework. It has a fairly high cost, so many people think about how to make it on their own. To do this, you need to prepare a workbench or table of the optimal size that replaces this tool, and you also need to have the ability to work with metal. During the process, you should be careful and careful so as not to harm yourself, as well as to get the perfect result of the work.
Do-it-yourself circular is made using the following components:
- rectangular profile pipe;
- corners formed from steel;
- engine.
How to make a hand saw from a grinder?
A home-made circular saw from a circular saw with your own hands is considered quite popular. Most often, a grinder is used for this work. To do this, only some changes are made with a ready-made tool, which is equipped with a special sliding stop, and an axial handle is also installed.
All work on independent creation a circular saw from a grinder consists of the following steps:
- A sliding stop is created on the tool, represented by two corners of small dimensions made of metal. They are installed on both sides of the main working body of the tool, represented by a disc with different teeth, used instead of the standard one. abrasive wheel. At the same time, a gap of 4 mm is left on each side.
- So that the installed corners do not cling to the part being processed during the use of the finished saw, they must be slightly rounded from below. Front and rear, they are connected by special cross-links, for which standard fasteners are used - bolts and nuts.
- A special collar is attached to the angle grinder itself, made of a tape formed from metal. At the same time, its screw tie should be at the bottom of the tool. A strip of tin is fixed to this clamp, folded in half in advance, and it can be replaced with galvanized. This element must have a special hole designed to fix the rear bolt of the sliding stop.
- Identical gaps are created between the stop of the future circular saw and its working body.
- In the gearbox housing, which is an important element of the grinder, from 2 to 4 threaded holes are created. They are designed to use small bolts. For this work, the gearbox is initially disassembled in order to determine exactly where it is possible to create holes in its body with a drill. It is with their help that the axial handle is fixed, which can be bought ready-made or made on your own.
- If it is supposed to perform the axial handle on its own, then a metal tube is used for this, and a metal bar can also be used, which has an unusual curved shape. In the created handle, as well as in the gearbox housing, holes for fastening are formed, after which the fixation itself is realized.
- Next, an adjusting rod is created, for which a small piece of a steel bar is usually used, and its thickness is usually 5 mm. One end of this segment is bent, resulting in a loop. A hole is created for the front stop bolt. Washers are selected on the front of the stop, which will allow you to get a uniform and optimal gap in width. On the other side of the rod, a thread is formed that enters the hole on the saw handle. To do this, a nut is screwed onto this hole in advance, and as soon as the assembly is completed, the second nut is also screwed on. With these nuts, which are easy to tighten or loosen, the optimal and desired depth of cut is ensured.
Thus, the process of creating a manual circular stove is considered quite simple. Here you do not need to use expensive tools and materials, and all work is easily implemented on your own.
How to make a desktop circulation stove?
You can even make a circular table with your own hands with drawings that are formed in advance, and are also high quality and correct. With their help, you can get a design that has high quality, safety of use and efficiency.
A full-fledged circular saw, formed in-house, is represented by a serious, complex and unusual design, which is created only with a preliminary consideration of all its elements, the study of drawings and the preparation of materials and tools.
It is important to decide whether the circular will be stationary or desktop, and the choice depends on how often the tool will be used, as well as what scale of work is supposed to be implemented with it.
The design of a standard circular saw
"Real" stationary circular
A do-it-yourself circular table, the drawings of which are freely available, is created easily and quickly if you know its design well. If all the components are separately formed and prepared, the result is that they are simply securely and firmly connected to each other, ensuring an optimal design.
Back to main elements this equipment applies to:
- Table. Usually it is covered with a sheet made of galvanized steel or tin. It is not allowed to use plastic or wood for these purposes, since these materials will not be able to withstand the significant impact of other materials, therefore they will be rubbed, resulting in deformations, bends and holes.
- Cross links. They are created for the table, and usually a steel corner is used for these purposes, the thickness of which is approximately 7 cm. These connections are equipped with a shelf attached to the outside in a horizontal position. In this case, the ease of forming the side limiter is ensured.
- The working body of the circular saw. It is represented by a toothed disc that protrudes beyond the table, as this provides a good sawing process for various elements.
- Motor equipment, which must be powerful enough. Its choice depends on the diameter of the saw. If it is supposed to work with lumber whose thickness exceeds 15 cm, then a very powerful motor is selected, therefore the process of creating a circular will be quite difficult, since it is difficult to find this element in the public domain.
- Side stop. It is made adjustable, and an even piece of steel corner is used to create it, the thickness of which is approximately 7 cm. This stop in length should be approximately 35 cm longer than the length of the table. One vertical shelf on each side is cut off, so it turns out to be equal to the length of the table . The tails, which are flat, curve down. Holes for threading are formed in their lower shelves. The emphasis is attached to the table with bolts, and it is set exactly according to the template.
- Shaft. It is an important piece of equipment, and it is desirable to purchase it in finished form so that it has high quality and reliability. Usually, the finished element has a special seat designed for the future saw blade.
- Bearings. They may be different, but the most the best choice are considered to be self-aligning elements that are ball-shaped. They are equipped with a double row of special balls. Inside the clip in the section is curvilinear. If you use cheap and low-quality bearings in a homemade circular, they will not last too long. The trunnions are equipped with covers that prevent sawdust from entering the bearings.
- Saw transfer. A V-belt design is usually chosen, since if a gear is chosen, it is considered dangerous enough for amateur use. This is due to the fact that if lumber is used that has previously been used for other purposes, then a nail or other fastener may get caught in it, which, when it enters the gear, can cause the engine disk to simply fly apart.
- Ratio. It is selected depending on the parameters of the engine, namely on its revolutions and on the frequency of rotation of the disk.
- Engine. Best to choose asynchronous motor, which is single-phase. Typically, standard washing machines are equipped with such elements. They are ideal for a homemade circular saw. It is not advisable to use collector motors, which are usually installed in different electrical appliances, since they give extremely significant revolutions, and also cannot work for too long, which is considered important for a circular.
- A three-phase motor is often used, but it is complemented by a starting and running capacitor, which are equipped with fittings. They have a significant value, and they must be either oil-paper or just paper.
- An engine starting circuit that can be used for a delta or a star, and it should not need additional refinement.
Thus, the process of creating a circular saw on your own is considered quite complicated, but if you know what basic elements the equipment consists of, as well as choose high-quality elements that are reliably and safely connected to each other, then the work will be done correctly on your own.
Read this article on the blog - be careful in experiments and working with sharp tools. Write reviews and share tips on working with saws and circular saws that you made yourself.
The vast majority of repairs and dacha works 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 it small wooden table under 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 of the above 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. Relatively weak and uncomfortable is the circular saw from the engine from 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 it is provided good quality cut;
- 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 box body and fix the saw with reverse side countertops 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 case. Of course, such alterations can be performed for power tools for which the warranty period has long expired.
In rare cases, it may be necessary to remove the instrument 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 of pine board, 40 mm wide and 20 cm long over size table. 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 tabletop.
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.
