Make a stationary circular saw

Technique and safety rules when using a circular saw

A circular saw is a potentially hazardous power tool. Safety rules when working with it are reduced to the prevention of mechanical and electrical injuries, fires and other damage.

Recommendations of manufacturers for safe work with circular saws:

  • use the saw together with a special system for removing chips;
  • work only with the use of personal protective equipment (glasses, respirator);
  • clean the saw with a suitable brush;
  • the minimum excess of the height of the riving knife over the saw blade is 5 mm;
  • replace the blade only when the device is completely turned off;
  • keep order in the workplace. A large amount of sawdust and dust must not be allowed to accumulate;
  • the requirement for work clothes: it should not be too loose, so as not to get into the working mechanism;
  • the power of the tool should correspond to the volume and nature of the work. For example, you cannot use a low-power tool for sawing a thick log;
  • use a circular saw only in a well-lit room;
  • keep the tool cable away from the working disc.

Damaged or deformed saw blades should never be used. Only discs of the diameter specified in the instructions for the tool are allowed. It is also prohibited:

  • work with wood that contains metal elements. Before starting work, all staples and nails should be removed;
  • using a saw in a state of illness or even mild discomfort;
  • operate a tool with a faulty start button;
  • use a saw with an incorrect blade position.

In the event of failure of one or more components of the tool, contact the service center. This is a guarantee that only original spare parts from the manufacturer will be used for repairs.

At 35, cuts much better, especially. thick materials.

The overhang of the saw, as seen in the photo, is about 9 millimeters. If you replace the table material with a thinner one, then this distance can be increased even more.

Circular Saw Case

The first two materials were cut easily and quickly, without the use of guides, simply by guiding along the mowing line drawn with a thin marker. The birch is sawn slowly, but it is sawn all the same. The power of the engine and the absence of guides affects: such a thick material will clamp the disc at the slightest distortion.

The next step is sawing other materials, alteration of the machine structure to a completely metal one. So it’s quite possible to make a homemade circular with your own hands, and it’s very simple.

Circular do it yourself

It is extremely difficult to make an accurate transverse cutting of the board with a hand-held circular saw in the standard version. To get the perfect cut in accordance with the markings, a simple home-made device, easily made from scraps in your home workshop, allows.

The cut-off device is designed for perpendicular cutting of boards from 100 to 250 mm wide in 50 mm increments, but its dimensions can be easily changed to suit your needs.


2.1. Before starting work, it is necessary to put on overalls and safety footwear to protect against the effects of hazardous and harmful production factors. Overalls must be of adequate size, clean and free of movement. 2.2. Before starting work, you need to prepare personal protective equipment, inspect them and make sure they are in good working order. 2.3. Before starting work, it is necessary to do the following:. prepare the workplace for work, for which remove unnecessary items, free the approaches to the circular saw, racks and stacks of wood, blanks;. turn on the general exchange supply and exhaust ventilation and local suction from the circular saw;. by external inspection, check the serviceability of general and local lighting, electrical wiring, connection of non-current-carrying parts of the machine to protective ground;. inspect the wood received for processing; in order to avoid injury, do not feed wood with defects (rot, rottenness, deep cuts, inclusions of foreign solid particles) for processing, as well as waterlogged and ice-covered wood and blanks. 2.4. Before starting work, you should check the serviceability and prepare the cutting tool for work. It is necessary to check the sharpening of the saw teeth; if the disc has broken teeth, cracks or other deformations, it is necessary to replace the disc. 2.5. The circular saw must not be allowed to operate if at least one tooth is missing. 2.6. The teeth must be sharpened, have the same profile and height. 2.7. Before starting work, you need to check the reliability of the disk fastening. 2.8. After checking the cutting tool, it is necessary to check the serviceability of the machine at idle, paying particular attention to the condition of the drive belts: their strength, belt tension, correct position on the pulleys. 2.9. It is necessary to check the presence and serviceability of protective fences; work on the machine must not be allowed if its moving parts are not guarded. All noticed faults of the circular saw and violations of safety requirements during preparation for work should be reported to the work manager and do not start work until they are eliminated.

It will also come in handy if it is necessary to reduce the length of the workpiece by a few millimeters, and it will cope with this task no worse than a miter saw.

The quality of the disc

There are several signs by which you can almost accurately determine whether the product is of high quality or made “on the knee”:

  • The disc must be marked, and the inscription is applied using a laser tool, and not paint.
  • The canvas should be subjected to the procedure of grinding and polishing. the cleanliness of the processing can be seen with a glance, if you “play” with the disc in the light.
  • The disc of the cutting tool is subjected to balancing and calibration procedures. the operation is conditionally similar to balancing a car wheel. The cutting tool after such processing will not “beat”, during operation there will be no vibration.
  • To compensate for possible thermal expansions, special slots are made on the disc, ending in small relief holes.
  • Some manufacturers reinforce the disc with several circular stiffening rings.
  • Another quality indicator is the name of the manufacturer, his trade mark. Today these are European, American, South Asian, Russian and Chinese manufacturers (listed in descending order of quality). By the way, some Russian manufacturers produce products that are comparable in some parameters with European or American.

In general, choosing the right blade for your circular saw is almost a science. If there is no experience, then it is better to turn to professionals for advice, and those who have the skill of working on a circular saw for at least 2-3 years.

Household and professional

A professional tool differs from a household one in the first place by its resource and the possibility of long-term continuous use. Household models overheat in this mode of operation, they need regular breaks in operation to cool down.

Also, professional power tools are supplemented with some special functions that will not be useful to the amateur master.

In addition, professional models are much more expensive than household ones.

The division into professional and household (amateur) is conditional. Some models may have professional functionality, but their design does not hold up in durability. Don’t put too much emphasis on classification. Be guided by purely practical considerations.

Main units, materials, tools

The algorithm for creating a circular saw with your own hands is quite simple. First, you need to determine for what purpose the circular will be used. If this is a small portable machine for working with laminate and plywood, then here it is worth thinking about a device from a hand-held circular saw, and if you have more ambitious tasks, then it is better to think about a more reliable engine and impressive dimensions of the machine.

In any case, you will have to make drawings of the device in order to calculate how and where the equipment will be installed, how the main parts will be attached, and at the same time think over what tool you need to work.

For a small portable circular saw from a hand saw, you can use the popular plywood or chipboard body assembly pattern. Well, if you plan to use a belt drive and a motor from a washing machine, then you will need a tool for working with metal. Welding work is indispensable here.


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.

Such a frame has turned out to be 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.

Homemade stationary machine

The proposed project of a stationary circular saw assembled by hand provides for the use of ready-made parts and assemblies. Assembly involves only a few turning parts. The model is based on an electric motor from an old washing machine.

Circular saw Hack || Make A Mini Chop saw Machine

From the 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 changes to the design, 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 designed for short-term operation, manufacturers recommend using it continuously for only 2-3 minutes, after which a break of at least 5-7 minutes should be taken. 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.

Do-it-yourself miniature machine from an engine from a washing machine

But as for the engine from the washing machine, then 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 engine from the washing machine is its power. It is designed for a long period of work, and for a circular saw this is the most important thing.

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.


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 ease of inclusion, 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.

Budget workshop: circular saw

In my free time from my main work, I am engaged in carpentry, and, therefore, as a Chukchi, what I see, I sing about that. And I did not start by buying machines and starting to work, but slowly accumulating tools, doing something myself, buying something, exchanging it, accepting it as a gift, and so on.

I believe that the main tool in carpentry is a circular saw. It’s just that, one way or another, we start with cutting the material. There are dozens of ways to do this without a circular saw, but for me it is still the main tool. So if you really want to work, you will have to get hold of such a saw.

I started out with a simple cheap parquet that was bolted to a chipboard sheet. A simple bar served as a parallel emphasis, which I fastened with clamps, but nevertheless it was already possible to work with it!

Now I want to tell you about a homemade plywood saw. I used it until the end of last year, until I bought a Bosch PTS10. And now she already pleases the new owner. I have the opportunity to compare it with Bosch, so Bosch does not always win. It is made of “parquet”, if you can call that a saw weighing more than 7 kilograms and a power of 2 kilowatts.

My saw starts from the base. Still, I don’t want 2 kilowatts of foolishness to fall and chase you across the floor, so the foundation must be reliable. Mine is made from old custom pallets, later two wheels were added to move.

It is based on the older model of parquet flooring from Interskol, with a soft start, and a 2 sq. All unnecessary has been removed. The plywood structure on the left is designed to maintain a stable angle of 90%. With such a weight of the engine, the native design does not hold the angle.

View of the engine from the other side. You can see the amplifier bolted to the table so that the table top does not bend.

For safe switching on, a classic starter is used, that is, in case of loss and return of electricity, the saw will not turn on itself. Safety first!

There is a table extension on the side, which allows you to cut about a meter from the rip fence. If necessary, the support folds down on the hinges. A parallel stop is visible on the table, which is fixed with clamps.

This is what my saw looks like with the table extension down. If you lower the disc, then it turns into a bedside table. There are wheels at the back for moving. All sorts of useful things are on the shelf inside

The parallel stop is realized with the help of two quick-clamping clamps, it is set along a ruler from the disc mowing line, it can be seen on the table. I wanted to embed a stationary ruler, but nothing went further than wanting.

Making a 2-in-1 Circular Saw Slide Guide (Easy Panel Saw)

There is a carriage for cross-cutting, it walks on three guides.

As you can see, spending a little money can get you a good beginner’s tool. Of course, I would not drive the moldings on it, but a lot of projects have been done on this saw. If you have a saw, you can even do without a planer at the initial stage. Everything determines the number of additional attachments such as carriages with different angles, tenons, stops and so on.

It all looks scary, but we’re talking about budget carpentry, aren’t we? And this allows us to work here and now, and not after we buy ourselves a circular for 50 thousand. For example, I still finish and finish my Frankenstein-Bosch in the title photo.

Circular saw machine

To create a circular machine, you need to competently approach its assembly. Only a device thought out to the smallest detail is capable of performing the tasks assigned to it. For small jobs, of course, it is better to use a circular saw based on a hand saw (Interskol, for example). This is both compactness in size and relatively low power consumption. To process larger workpieces in large quantities, a stationary machine is required. Consider the most important components of the circular machine.

  • The table for the machine tool can be made in many ways, even from an ordinary kitchen one. The main thing that needs to be achieved is the durability and strength of the structure.
  • The working tool is a disk. It should extend beyond the table by a maximum of one third of the diameter. It is best used for processing workpieces less than 150 mm thick, otherwise such a machine is unlikely to work.
  • Shafts and transmissions. The best solution is to install the finished shaft under the tool, since the manufacture of the shaft requires special equipment and skills in order to avoid errors and equipment failure. V-belt drive will provide greater safety and smooth running.
  • Motor. Among motors for circulars, a drive from a washing machine with its high efficiency and a longer service life is always popular.

let’s say that a homemade circular saw is capable of solving a fairly wide range of everyday tasks. The optimal and easy-to-execute option is to make a jointer and a circular saw on the same bed. Plus, both tools will rotate from the same electric motor. This feature will greatly facilitate our task. Its design will not necessarily be complicated, the main thing is to think over all the details, make drawings, carry out the correct assembly.

Circular from an angle grinder

If you have your own “angle grinder” that’s very good. To create a “circular“, you need to make an axial handle and a sliding stop to the unit. The design of the sliding stop includes a pair of steel angle pieces placed on the sides of the saw blade. With the help of nuts and bolts, they are connected by a transverse bundle, and the gap between the working part and the sidewalls of the structure will be provided with washers.

On the “angle grinder”, it is necessary to pre-tighten the band clamp made of metal with a screw tie down. Then you need to attach the double-folded metal strip to the holes for the sliding stop. The stand and clamp can be combined, but in this situation the metal strip will be too thick.

Then, in the gearbox of the future tool, you will need to make several holes for the bolts. For this purpose, the body is disassembled, and the points where drilling will take place are indicated. With the help of the holes made, the axial handle is fixed, because the “standard” handle will not allow you to make a good cut, even if the master has very strong hands.

The handle is created from a metal tube or rod. Designs can be shaped like horns or staples. The ends of the element with which it will be attached to the gearbox must be provided with holes for installing fasteners.

You also need to make a barbell that will regulate the process. For this purpose, you need to take a piece of metal rod, make a loop from one end of it, rivet it slightly and make a hole for the front stop bolt.

At the other end of the rod, you need to make a thread that will allow you to connect it to the handle. In advance, one strong nut should be screwed onto this thread, and after the structure is assembled, the second. By lowering and pulling them, you can adjust the cutting depth. By the way, if you use a drill instead of an angle grinder, you can make a similar tool.

Thus, you can independently make a good circular saw out of an ordinary angle grinder, with which you can cut various materials.

How to make a circular saw with your own hands?

A circular saw will always help to cope with many household and construction tasks. Making it yourself is not as difficult as it seems at first glance. It is enough to adhere to simple rules in working with metal, to have suitable materials at home or in the garage. If you briefly describe the design, then you need to do the following: you will have to build a workbench for a saw of the required dimensions and adapt a hand-held circular saw for it. A stationary machine of this type will greatly facilitate the work and increase its volume. So, let’s look at how to make this tool yourself.

Circular table materials

For the production of the circular table, I used 3 mm sheet steel. cut off two squares measuring 45×50 cm.I marked a window for a saw blade with a protection measuring 26×200 mm and cut it out with an angle grinder, trimming the edges with a file.

Drilled 4 holes with a diameter of 6 mm at the base of the circular saw to attach the saw to the table.

Home circular saw bench

Such a frame can be made in a domestic environment. There are two versions of the drive with a power not exceeding 1.2 kW. This is done in order to exclude increased power consumption. The structure of the first drive may include an electric drill of the specified power. This design is ideal for the home, but for professional work, its use will no longer be appropriate.

The bed consists of a work table and a base. To simplify the mechanism, you need to achieve this as much as possible in the disk mount. There are three main options: a hand-held circular saw on a tabletop, a connection between a blade and an electric saw chuck, shafts driven by a motor.

The table must have a solid and rigid base to ensure safe operation. In everyday life, there can be many options, it all depends on the author’s imagination. An important design parameter will be the cutting thickness of the workpieces.

Converting a hand-held circular saw into a stationary one

To make working with the circular saw more convenient.

Make a strong and stable frame by fixing the pallets to each other in the upper and lower parts with bars.

On a sheet of plywood, draw the line in the center and find its middle.

Measure 11.5 centimeters from the center in each direction.

Drill holes with a screwdriver.

To prevent the saw blade from touching the edges of the tabletop, the groove should be 8 millimeters wide.

Install a hand-held circular saw into the resulting groove. It is important to keep the saw straight: the blade must not touch the table top.

Fix the saw with a screwdriver.

Clamp to fix the saw start button.

Turn the saw over so that the blade is at the top.

To prevent protruding screws from interfering with the work, remove them with an angle grinder.

Fix the tabletop to the frame with screws.

To cut parts of the same width, make a limiter. Using a ruler on the outer edge of the saw blade, measure 10 centimeters on one side and on the other.

At these points, fix the bar (limiter).

From my youth I dreamed of having a circular. But, somehow it did not work out, and there was no garage or other room where I could place and work. When the garage appeared, I gradually began to realize my long-standing desires. The idea to build a circular saw from a hand-held circular saw I took from YouTube. I bought almost on a used Einhel 1800 W ball, put a new saw blade and put the saw in the box. The assembly process itself can be seen in the photo. The working surface of the table was covered with several layers of furniture wear-resistant acrylic lacquer. As a longitudinal stop, a regular rail is still used. Instead of a carriage, I built a temporary movable plywood structure. I will make a permanent stop and a carriage when, after working, I understand what I am from. I want them and what they should be in design. Oh, and she saws! The relic! All that I wanted. I sawed it in the first days))) For different garage crafts. what you need.

Looking ahead, I answer possible Комментарии и мнения владельцев:. yes, I understand that all this is nonsense and there will not be much accuracy here. But, nevertheless, this is a hundred times better than sawing with a hand hacksaw or looking for someone to cut the plywood or dissolve a lath for me, and even pay money for it I solemnly promise not to make furniture on this machine, at least in style of the era of Louis XIV)))

List of required materials: hand-held circular saw; plywood 11 mm; bolts М-8 with a furniture head; screws; switch; the wire; timber 40×40; furniture rails.

List of tools: electric jigsaw; hand-held circular saw; drill; electric screwdriver; a hammer; screwdriver; pliers; ruler.

How to assemble a stationary circular saw

For more convenient work with the machine, the craftsman made a movable stop on the furniture rails.

Aluminum corner served as a longitudinal stop.

To adjust it, loosen the bolts and move it to the distance required for further work.

However, in this position, the saws will be lost 10-20 mm.
