How to make a circular saw with your own hands. DIY stationary circular saw. Detailed instructions. Assembling the saw table

A hand-held circular saw is a powerful mechanism with significant productivity. One of the key advantages of a circular saw is excellent maneuverability. But there are also disadvantages, especially if large sizes of wood need to be cut. To make the process easier, you can simply make a table for the circular saw yourself.

Design requirements

Experienced craftsmen are ready to create a table for a circular table with their own hands without any techniques or drawings. However, certain conditions still need to be taken into account.

The essential requirements include:

The availability of different functions depends on the working conditions and wishes of the specialist. These include the ability to carry out high-quality longitudinal and transverse cuts.

Standard products, of which there are hundreds in shopping centers, are made of stainless steel. This is wonderful material , but further we consider the production of a table for a saw from wood.

Table design for a manual circular saw is so elementary that most specialists produce it without preparatory drawings and techniques. This is a dense workbench that is created from wood and plywood.

The most durable table bases are made from alloy. They are the heaviest and require the presence of welding skills. Therefore, stands are often made from leftover lumber. A circular saw is attached under the tabletop, and the drive protrudes above it through a specially made slot. The lumber is advanced along the table top and sawn with a disk. For convenience and correct operation, the table is equipped with additional devices: an angular and longitudinal stop.

The tabletop “absorbs” part of the working plane of the disk; the depth of cut will decrease by the thickness of the tabletop. For this reason, it is preferable to choose a circular with the largest disc diameter, and the table cover is thin but rigid.

If you have not purchased an electric saw yet, choose modifications with high power (from 1200 W). They can handle cutting large-sized wood. Holes will be drilled to secure the base. The solid base may burst. For this reason, it is advisable to select a mechanism of a different type.

Material selection

To make a circular table with your own hands, you need to remember carpentry skills, have a lot of patience and a small number of materials and devices.

Materials:

Devices:

• jigsaw;
• screwdriver;
• drill;
• ruler.

The volume of the countertop will depend on the workshop area. At the same time, it will be uncomfortable to saw large pieces on a small table. If the part is completely fits on the working plane, the cut is made smoother and more accurately. The height of the legs is chosen depending on the height of the master.

Working with a circular saw is very dangerous, for this reason you need to worry about protecting your fingers. Cut a pusher from a piece of wood or furniture board.

Additions to the completed design

Some craftsmen, when assembling a table for a hand-held circular saw according to unique drawings, completely remove the factory safety cover and replace the factory platform with a homemade one. If cutting at an angle is not planned, you can remove all devices for adjusting the tilt of the disk. The electric saw is fixed directly to the new base, which makes it possible to gain a couple of millimeters of cutting depth.

Without inner casing it is easier to remove the disc; the electric saw will not become clogged with shavings when working with wet boards. Dismantling will require extra time, but the service life of the motor is preserved and overload is prevented.

Mounting a circular saw

The matter remains small. The circular electric saw is located inside the prepared hole. The sole is secured with bolts, and the gear drive must fit freely into the socket.

The table for the circular saw is almost ready. Now it needs to be treated with a moisture-protecting material, then coated with varnish in several layers (to minimize slipping).

The resulting system can be supplemented with anything at the user’s discretion (safety cover, device for adjusting the tilt of the disk, carriage, etc.).

A few words about electronics

A circular saw is electrical special equipment that operates from a 220 V power source. If the user has sufficient knowledge and skill in the field of electronics, he is able to bypass the start and pause keys of the saw, and then move them to a convenient place (usually the outside 1st of the stiffeners).

If the model seems complicated, you need to tighten the start button with a wire, and turn on the special equipment using a power cord. However, this method is bad because it eliminates the possibility of quickly turning off the device in the event of an emergency.

Safety requirements

1. One of the most common causes of injuries when using a circular saw is considered to be a cluttered workplace. In addition, it is important to monitor the stability and strength of absolutely all components of the system, and if there is imbalance, take measures to eliminate difficulties.
2. Before connecting the saw, you must make sure that it is well secured. If necessary, tighten the screws/bolts.
3. It is strictly forbidden to hold the material close to the cutting site! This is dangerous as knots and chips bounce into the eyes or onto open parts of the body. Be sure to wear glasses before work and clothes with sleeves.

Making your own saw table is not as difficult a task as it might seem. If you have good material at hand, its characteristics are chosen correctly, and the power of the device ranges from 500 to 1000 W, the above instructions will be the basis of the work.

You should not lose sight of the fact that at any stage of table production you should control the accuracy of your own operations. Otherwise, if deviations in size or deformation of the legs appear when the ribs are tightened, it will be very difficult to restore stability. Nevertheless, making a table for a circular table with your own hands is an absolutely realistic task that will take several hours.

Additional Important Information

Carpentry work requires special attention. If you want to make a high-quality and highly reliable table for a circular saw with your own hands, then be well prepared for the work.

Do the following:

Using this article as inspiration, you can make a durable table saw stand for your circular saw.

Those people who often do carpentry work for themselves or to order, simply need to have a stationary circular saw in their carpentry workshop. Working on a stationary machine is very convenient and, again, the back position is straight, which is important during long and monotonous work.

Today, stores have a large selection of machines and tools, but a simple carpenter cannot afford a couple of them and has to get out of the situation using natural ingenuity. For example, a master made a stationary saw from a hand-held circular saw, how did he do it? Let's look further.

The process of creating a stationary circular saw.
And as was said above, the author made his circular saw from a manual circular saw, and no changes were made to the design of the saw. Here a table is simply made, and the saw sole is attached to the underside of the tabletop, where a cut for the disk is first made, holes are first drilled and then sawn. The base is created from plywood and 40x40 timber.

Then a tabletop is cut out of plywood; the author recommends using laminated or varnished, because the surface is even and smooth. As agreed, the cut is made, and holes are drilled in the corners for subsequent fastening.

A circular saw is attached to the underside of the tabletop using M-8 bolts, mainly the bolt heads should be sunk into the plywood.

The switch is installed and connected, the start button on the saw is fixed in the pressed position, and the switch is connected to the outlet, so there is no need to disassemble the saw or connect anything to it.

Also, for ease of work, a movable emphasis was placed on furniture guides.

The longitudinal stop is made of aluminum angle.

To adjust it, you need to loosen the bolts and move it to the distance required for subsequent work.

But as you understand, with this installation of the saw, 10-20 mm will be lost.

And this is exactly what the author came up with.

Also presented to your attention is video material from which you will learn a lot. Enjoy watching!

It is not difficult to assemble a circular saw with your own hands. Homemade devices are often found in the workshops of people who have the necessary skills to work with tools.

All actions during manufacturing must be performed carefully, observing safety regulations.

Drawings of the device will make the process of assembling a circular saw with your own hands more understandable.

Assembly order

A homemade circular saw can be easily assembled with your own hands if you have an unnecessary grinder in your home workshop.

To complete the assembly of the device, you need to prepare the following materials and tools:

• Bulgarian;
• aluminum corner;
• nuts;
• metal rod or pipe;
• metal sheet;
• sliding stop (needs to be assembled);
• axial handle (needs to be made).

First of all, a stop with the necessary holes is constructed. It is constructed using short parts of a metal angle. The corner trims will be located on both sides of the toothed disk.

For them, it is necessary to make recesses on the sides with a depth of 0.2 to 0.5 cm. To ensure that the lower edges of the corners do not come into contact with the element being cut, they should be smoothed.

The parts are secured at the back and front with transverse ligaments using nuts and bolts.

The assembly diagram of the stop is not complicated. A metal clamp is placed on the body, the tie of which is made from the bottom of the device.

Then a hole is prepared through which the product is secured with a clamp for rear fastening, which secures the stop for subsequent sliding.

In the gearbox of the device, holes with threads are drilled into which small parts will be attached.

At the beginning of work, the gearbox is disassembled to determine a suitable place where the recesses will be made.

Recesses are required for subsequent fastening of the axial handle. If you use the handle located on the side of an ordinary angle grinder, then making a hole will be quite difficult.

The next stage is making the handle. The part can be constructed using a rod or tube made of metal bent upward. Its ends will later be attached to the gearbox.

If the handle is made in the form of a horn, then its far end should be flattened and recesses made for the axle. A forward-facing part is inserted into the recesses located in the gearbox. The edges of the part are pressed.

Using washers under the front part of the stop, the gap parameters are equalized along the entire length of the circular saw.

If you use a 0.6 cm rod, you will need thin washers. A thread is applied to the back of the rod.

The part is then placed into the recess on the handle. The device is now ready for use.

When operating a circular saw, you must follow safety rules, especially you should not drink alcoholic beverages, as their consumption leads to impaired coordination.

Table saw assembly

Assembling a circular saw with your own hands at home is not a very difficult job; you just need to prepare all the necessary parts and tools, select the design and follow the drawings and instructions exactly.

A table circular saw is easily assembled from a regular one. The finished device will have compact dimensions.

To do this work, you need to assemble a frame from a thin tube or rod 18 - 20 mm, made of metal, to which the lever is attached.

The part of the structure located below must be bent in the direction of the cut. This element is attached to the table with self-tapping screws.

The stand for the device must be stable. Rocking the saw while working can be very dangerous because any careless movement can result in the loss of fingers or an arm.

It is best to make your table out of metal, securing its supports to the floor.

On the crossbar you need to place a lever made of a tube in the shape of the letter “T”. The lever should turn freely.

The part is cut across into several sections. After completing the installation of the structure, all elements are connected using clamps.

A homemade mini circular saw is pulled and fixed with clamps to the vertical outer part with your own hands.

The assembled circular saw can be used in the home workshop as a cutting tool. Before starting work, insert a cutting wheel into the grinder.

To process thick boards, you need to use a full-fledged machine. The carriage is used to trim the elements. It is assembled from several beams attached to the base and performing a guiding function.

Having understood how to assemble the device, you need to select the materials and tools suitable for the job. At a minimum, you will need a working grinder and various consumables.

But to assemble the device yourself, you need special skills. If you do not have the necessary dexterity, then it is better to purchase a circular electric saw, in the correct, reliable and safe operation of which you can be absolutely confident.

The described method allows you to assemble a small circular saw that can be used in a home workshop or your own shed.

How to assemble a stationary device?

Having learned how to make a circular saw, we begin to assemble the device. A stationary saw differs from a mini tool only in the size of the saw blade.

The statina must have a base of sufficient width without curvature, with a cutout for a saw. More often, the base is made using plexiglass, plywood, chipboard and ordinary sheet metal.

The parameters of the closing surface are determined taking into account the pressure exerted on the statin. The power cord for the circular saw is also attached to the base.

The statin cover must be freely removable, since access to the machine may be required at any time.

The table for the structure will need to be made independently.

It is covered with a tin or steel sheet, since the wood passing over plastic and wood during work gradually forms grooves on the coating. Because of the holes and indentations, it will be very difficult to make a quality cut.

If the plank is planned to be sliding, then it is necessary that the table surface have absolutely parallel opposite edges.

For smooth sliding along the edges without changing the desired angle, slides are made using an aluminum corner.

The cutting disc should protrude no more than a third of its diameter above the table surface, otherwise the tool will be dangerous to life.

But even a minimal protrusion of the cutting element can cause serious injuries if used incorrectly.

Before starting work on assembling a circular saw, you should compare the power of the existing electric motor with the required one. Parts with a thickness of more than 150 mm will be quite difficult to saw with a homemade machine.

The stop, which can be adjusted during operation, is made from a fragment of a metal corner 7-8 cm. It should be 40 mm longer than the tabletop.

Then a stop is placed on the surface of the table, which is secured with bolts. The emphasis is set according to special measurements previously established between the working part of the device and it.

A stationary circular saw is a machine that should be in the workshop of every craftsman who works with wood. With its help, you can quickly and effortlessly saw a board, cut a workpiece of the required size, or cut firewood.

A home craftsman simply must acquire such a machine. It is not necessary to buy it; a homemade circular saw is guaranteed to cope with the volume of work in a home workshop, and will cost a significantly less amount.

Circular saw device

Being a truly useful tool, the circular saw has a fairly simple design. Its main components:

• bed – frame on which the main units are mounted;
• tabletop with a slot for a disk;
• engine with rotation transmission system;
• cutting tool, disc with teeth.

Optionally, the device can be supplemented with a pusher, which ensures progressive movement of the workpiece towards the disk, and various lifting mechanisms that regulate the cutting depth.

The principle of operation of a circular saw (circular saw) is that the rotation of the electric motor shaft is transmitted to the cutting tool, a disk with sharply sharpened teeth. The center of the disk is located below the level of the tabletop, only a segment of it is removed from it. The workpiece is brought to the rotating disk, the teeth bite into the wood, creating an even cut.

A simple circular saw from a grinder or circular saw

An angle grinder (grinder) is one of the most popular home craftsman tools; with its help it is easy to cut metal and clean welds. In addition, using a wood disc instead of a standard abrasive disc, the grinder can be turned into a hand-held circular saw (it is also called a parquet saw), and by making a frame with a table, it can be turned into a stationary circular saw.

Required accessories

To work you will need:

• multilayer plywood with a thickness of 10 mm or more;
• switch and wire;
• countersunk head bolts;
• screws;
• wooden block 40x40 mm.

You also need to prepare a drill or screwdriver, hammer, screwdriver, pliers, ruler and pencil. Using these tools you will have to make a circular saw with your own hands.

Of course, you must not forget the grinder itself or the hand-held circular saw. At the first stage, it will help to cut the material, and then it will take its place as the working body of the circular saw.

Sequencing

The first step is to make the body of the circular. Thick plywood is perfect for this; you can use any pressed wood boards. You will need to cut four rectangular sheets, size 40 x 80 cm. They are used to assemble a box with a square 80 x 80 cm at the base. For ease of assembly and reliability of the structure, four bars are installed in the corners.

The resulting box is closed on top with a tabletop. It can be made from the same plywood, but it is better to use some sheet material with a laminated coating. This guarantees the durability of the machine and ensures ease of use of the homemade circular saw.

A cut is made in the tabletop to allow the disk to come out, and holes are drilled on the sides for attaching the tool.

The grinder must be securely fixed under the tabletop. The design of the latch can be very diverse, it all depends on the configuration of the machine itself. The main requirement for fastening is that it must securely hold the angle grinder without allowing it to move.

The simplest fastening may look like this: two metal squares, a grinder is fixed between them with a steel clamp.

Two holes are drilled in the upper shelves of the angles holding the angle grinder. The structure is secured from below to the tabletop using countersunk bolts. All that remains is to block the power button and connect the angle grinder via an external switch.

In the same way, you can make your own circular saw from a circular saw. In this case, the work is noticeably simplified due to the fact that there is no need to invent a fastening. It is enough to make a cutout for the disk, drill holes along the holes of the plate with a hand-held circular saw.

Miniature machine made from a washing machine engine

The circular is distinguished by its extreme simplicity and availability of materials for its manufacture. Perhaps its only expensive part is the electric motor. Stationary machines are equipped with a powerful asynchronous motor, which ensures cutting of thick wood of any species, but in a home workshop you can limit yourself to less power.

Note! To cut boards of medium thickness, it is enough to make your own circular table driven by a washing machine motor.

This design has a number of advantages. An engine from an old washing machine is inexpensive; moreover, a similar unit can probably be found in a home craftsman’s household. Connecting this motor is not particularly difficult; there is no need to look for circuit diagrams or do soldering. With all this, the power of such a unit is quite sufficient for most types of work.

The machine diagram can be simplified as much as possible by eliminating the belt drive. In this embodiment, the cutting tool will be mounted directly on the motor shaft. The base of the desktop mini-machine will be a frame assembled from a block with a cross-section of 40 x 40 mm. If desired, it can be welded from a corner or profile pipe.

Part of the body of an old TV, coated chipboard, is ideal as a stand (tabletop) for a circular table. As practice shows, this part is quite durable, and thanks to the varnish coating, it does not prevent the workpiece from sliding.

Using a jigsaw, two parallel cuts are made in the tabletop perpendicular to the cutout for the disk. A movable square will slide along them, playing the role of a side stop. It will help you make an even cut, if necessary, at a given angle.

Stationary machine

Those who plan to get serious about woodworking should think about making a full-fledged stationary circular saw. This should be a separate unit installed on a workbench, equipped with a powerful motor, with the ability to quickly replace the disk. Making such a circular with your own hands will take time, but it will definitely pay for itself.

Despite the apparent simplicity of this device, before starting work it is worth creating a drawing of the machine. This will allow you to clearly see the future unit and choose its optimal configuration.

bed

The basis of any machine is the bed, the frame on which all the main parts are mounted. The frame of the circular saw must be stable and reliable, which is why it is made of metal. It is preferable to use a profile pipe or a thick-walled angle. Welding is used to connect parts. If a collapsible structure is planned, a bolted connection is suitable.

Buying a suitable material will not be difficult; in any specialized metal store you can pick up both pipes and an angle. Those who want to save money can be advised to contact scrap metal buyers. You can buy the same thing from them, only cheaper.

Tabletop

The best material for making the tabletop of a professional circular table is metal. Steel and aluminum-based alloys are excellent. For a budget option, you can limit yourself to thick multi-layer plywood covered with sheet iron. In any case, the surface of the tabletop must be smooth, resistant to friction and not bend under a weight of up to 50 kg.

A groove is made in the tabletop for the disk. It can be done in two ways. You can make a cut in a single sheet, or you can assemble a tabletop from two halves. The second method is preferable for a metal tabletop, which is difficult to cut into at home.

If desired, you can make a sawing machine for work outside the workshop; for this it is enough to provide the possibility of installing a low-power gasoline engine; it can be removable.

Rotation transmission

The optimal drive for a circular saw is a V-belt drive. Two pulleys are used, one on the engine and one on the drive shaft. It's convenient and safe. There is no direct connection between the motor rotor and the disk; if the tool jams, the belt will begin to slip, signaling the need to turn off the power. In addition, using pulleys with several grooves of different diameters, you can adjust the speed of the saw, choosing the optimal mode for different types of wood.

Rotation from the motor rotor is transmitted to the shaft. This is one of the most important parts of the circular. It is unlikely that you will be able to make a shaft yourself; it is better to buy a ready-made one or order it from a turner.

The shaft is mounted on bearings. They must be of a closed type: a circular saw is a sawing place and open ones will not last long.

Machine with pendulum engine suspension

Those who can boast of the ability to work with metal can be advised to make a circular saw with a pendulum engine suspension. The main feature of the device is that the motor, shaft and cutting disc are installed in one common frame. On one side it is hinged to the frame, the second is held in place by a screw with the ability to adjust the height. By changing the length of the screw, you can adjust the height of the disk exiting the tabletop.

This system allows you to adjust the cutting height, as well as use discs of different diameters. If, instead of an adjusting screw, you use a probe placed on the tabletop, you can get a simple copying machine. The feeler gauge will allow you to adjust the cutting depth according to a certain pattern. This fairly simple modification will turn a simple circular saw into a real woodworking machine. With this device you can not only cut the board into the necessary pieces, but also make precise cuts and make various selections.

Many summer residents and owners of private houses were faced with the need to process and saw boards, plywood and other lumber. For such work you will need a circular saw, which will not be difficult to do using available tools. Such homemade equipment will not be inferior to purchased equipment in functionality and quality of execution, allowing you to save several tens of thousands of rubles on the purchase of ready-made units.

Description of equipment

DIY circular saws can be stationary or portable. The design of the simplest circular saw will include a metal or wooden supporting frame, inside of which are mounted an electric motor, an electricity supply control unit, a table top and the working saw itself, which is mounted on the circular saw shaft or installed through gears and a trunnion mechanism. The saw is located in a slot in the tabletop, which makes it easy to cut lumber, performing high-quality wood processing.

The table top can be made from lumber or you can use ready-made metal blanks for this. Smooth easel tables are made from wood, The top of such a tabletop will need to be covered with a durable metal sheet. Otherwise, without metal protection, the wood will begin to wear out quickly, and the equipment will last several years during active use, after which complex and expensive repairs will be required.

First of all, you need to decide on the main tasks of the sawing machine. If you need to cut boards or firewood for the winter, then a simple installation of a sturdy table with a slot for a disk will be sufficient.

Some models imply the presence of an additional shaft to which knives, a jointer and a plane are attached. Such universal machines are equipped with powerful electric motors, which allows you to perform a wide range of wood processing work. When manufacturing a multifunctional machine, it is necessary to be guided by high-quality diagrams and drawings that will allow you to create universal and reliable equipment.

If you need to perform various types of carpentry work, then set up a coordinate table with guides. The existing stops and guides can be fixed at different angles, which allows not only to ensure safe operation of the machine, but also to perform high-quality wood processing, easily changing blades to saws of different diameters.

Advantages of homemade equipment

Homemade circulars are very popular due to their ease of manufacture, durability and reliability. Today, many summer residents use homemade units rather than buying expensive equipment in specialized stores.

The main advantages of this technique include the following:

• The versatility of the tool.
• Ease of manufacture.
• Possibility of significant savings.
• Reliability and durability of equipment.

The designs of stationary and mobile circular saws available on the Internet and in thematic printed publications make it possible to produce equipment for processing both thin workpieces and thick lumber. You can choose the simplest options that do an excellent job of processing lining, thin slats and plywood.

Characteristics and power

The functionality of using the equipment will depend on the correct choice of parameters, including speed indicators and drive power. The power rating is affected by the maximum permissible diameter of the toothed saw. It is believed that to process lumber with a thickness of about 10 millimeters, an electric motor with a power of 1 kW will be required. Based on the thickness of the processed and sawn timber, you should select the power of the electric motor.

Transmission from the drive in a self-made circular machine is best done using a V-belt. This allows you to ensure the necessary safety of using the equipment. When foreign objects get under the saw, the V-belt drive will slip on the pulleys, which eliminates injuries and jamming of the working disk.

Making a circular saw

Before proceeding directly to the manufacture of a circular machine, it is necessary to think through its structure and design, and ideally, select a drawing diagram according to which all work will be carried out in the future. When planning the manufacture of the frame, it is necessary to remember that such a design must be stable and reliable. For industrial powerful saws, the base is made of reinforced welded metal structure. For household models, you can use wooden blocks with plywood for the frame or weld a base from a metal corner.

The choice of electric motor used will depend on what kind of work and what kind of wood is planned to be processed on the machine. The drive can operate from a single-phase electrical network, or powerful industrial motors are used that operate from a three-phase electrical network.

You can make a powerful and easy-to-use circular saw from a washing machine motor. This won't be too difficult. Such motors are compact in size, operate on a single-phase network with a voltage of 220 volts, are reliable and are capable of operating at high speeds.

One of the most important components of a power saw is the shaft on which the working saw is mounted. You can use a ready-made shaft from similar equipment or make it using a milling cutter from round timber. Turn the shaft on a lathe, checking for perfectly accurate centering. Even minimal shaft runout is not allowed, since in the future it will be impossible and unsafe to work on such an incorrectly centered circular machine. Seats for pulleys and a circular saw should be made on the shaft.

The saw blade should rise above the surface of the worktop by a maximum of one third of its diameter. Otherwise, with a higher saw height, it will be difficult to process wood, and working on such a machine will simply become dangerous. If it is necessary to work with timber, the diameter of the saw blade will be approximately 350 millimeters. To process boards, you should choose small discs with a diameter of 250-300 millimeters. The quality of the saw blades used must be given due attention, since in the future the mini-circular saw will bear a significant load, low-quality blades will quickly become dull and require replacement.

Materials and tools

Making a circular saw with your own hands is not particularly difficult. For this work you will need the following materials and tools:

In each case, the design of the circular machine will be different, so it is necessary to select certain components, which will allow us to produce functional and reliable equipment. When using lumber to make a base and desktop, the wood will need to be coated with impregnations that protect the material from rotting and moisture.

Step by step assembly

You can make a stationary circular saw with your own hands from a grinder and a hand cutter without making any changes to the design of the working tool. The base is made of lumber, which significantly simplifies production, eliminating the need to use complex welding equipment. Step-by-step instruction:

This option for making a circular saw will be an excellent choice if you need a tool for cutting boards up to 3 centimeters thick. If you need to make a powerful and multifunctional device for your home, then use electric motors with a power of 5 kW or more, which allow you to process and saw boards 5-8 centimeters thick.

Making a homemade circular saw is not particularly difficult. You can use grinders or hand saws, which are mounted inside the wooden base of the machine.

Some craftsmen make more complex tools that involve the use of powerful electric motors, V-belt drives and larger diameter saw blades. If you have any difficulties, you can find thematic videos online that tell you how to make a circular saw with your own hands.
