How to make a circular with your own hands. How to make a circular machine with your own hands. Support leg attachment

A homemade circular saw is a kind of handy tool that can cope with a number of construction tasks at home. In principle, it will not be difficult to make a circular yourself even if you do not have any special skills, the main thing is to have at least a little idea about working with metal. The necessary material can usually be found in a garage or home workshop, and a steel corner, a rectangular profile pipe and an engine are suitable here. The assembled circular saw can be put on an existing workbench, or, in the absence of such, you will have to build a table for a circular saw with your own hands. As for the motor, you can use the unit from the old washing machine or walk-behind tractor, but first things first.

Hand held angle grinder

If there is a “grinder” on the farm, then there is no better device for a hand-held circular saw. Don't know how to make a mini circular saw at home from such a popular tool? Do not despair, because its manufacture only involves providing a sliding stop and an axial handle to an existing unit. The sliding stop includes in its design two pieces of a metal corner of a small section located on both sides of the saw blade. With the help of bolts and nuts, the corners are connected on the front and back sides with a cross ligament, and the technological gap between the sidewalls of the thrust structure and the working element will be provided with washers.

It is necessary to put on a metal band clamp on the grinder so that its screw tie is located at the bottom, and a strip of galvanized metal with a hole for the sliding stop, folded in half, is already fixed to it. In principle, a special clamp with a stand can be made as a single unit, but in this case, the thickness of the metal strip will ideally be at least one and a half millimeters. Further, in the gearbox housing of the future circular, you will have to make a couple of holes for the bolts, for which it is disassembled, and the drilling points are determined. Through the holes made, an axial handle for a circular saw assembled from a grinder is attached, since the existing handle will not allow high-quality cutting, even if the master has remarkable physical strength.

The axial handle, which will be supplied with a circular grinder, is made of a metal rod or tube. The design in shape can be a transverse bracket or a kind of horn. The ends of the metal part, with which the handle is attached to the gearbox, are provided with holes for fasteners. There is one important point here: the ends cannot be riveted in order to eliminate the deflection of the handle during the operation of the hand-assembled circular. It is also necessary to make an adjusting rod from a piece of metal rod (4 - 6 mm), for which we bend one end into a loop, rivet a little and form a hole for the front stop bolt. The uniformity of the gap, as usual, is regulated by washers.

At the other end of the rod, a thread is cut, thanks to which it will connect to the handle. First, one nut is screwed onto the thread, and after assembling the structure, the second one. By tightening and lowering the nuts of this fixture for a homemade hand-held circular saw, the depth of cut is adjusted. This is how at home you can convert the grinder into a full-fledged disk tool designed for cutting various materials. By the way, by remaking a circular from a drill, you can achieve a similar result.

Miniature Tabletop Circular Machine

The mobility of the element is achieved by sawing a horizontal segment into two uniform parts, which, after installation, are fastened with clamps. A circular saw is fixed to the vertical part of the frame on the clamp. A table from a hand-held circular saw assembly can function as a cutting machine if a standard cutting disc is installed on the grinder. It is worth noting that the through cut here will not exceed 80 mm, and for processing larger lumber, a more serious home-made circular machine will be required, which will be discussed later.

Stationary machine

Circular machine, as close as possible to factory models, requires a competent approach to assembly, therefore, before making a stationary type circular saw, you need to think through everything to the smallest detail. In principle, a desktop mini circular saw differs from a stationary one in the height of the bed, which directly depends on the nature of the work performed and the dimensions of the workpieces that the device will process. One-time work can be carried out on a compact table saw, while a circular saw from a hand-held circular saw can be easily hidden in a barn or pantry, and a carpenter who constantly manipulates lumber will need a stationary home-made circular saw. Below is a diagram that details all the elements and fixtures for a circular saw of this type.

As can be seen from the figure, home-made circulars of this type have a clear design, and drawings similar to the one presented above greatly facilitate the process of their assembly. Before you make a circular, as well as mount a circular table with your own hands, we will consider each detail of the unit separately in order to know all the intricacies of its operation and installation.

Circular table

A table for a manual circular saw with a slot in the center is sometimes remade from an ordinary kitchen table or assembled from bars or metal profiles. Experts strongly recommend covering the table for a circular saw with a sheet of galvanized metal, since without a coating, the base is threatened with abrasion in the center from constant friction of the lumber, which in turn will negatively affect the quality of the cut, and the depth of cut will be uneven. The cross ties that reinforce the saw table are best made from a 60 - 80 mm steel angle with the horizontal segment outward in order to simplify the installation of the side limiter. A home-made table on which a circular saw will be installed must be strong and stable, and it must also be securely fixed in a fixed position.

saw blade

The toothed disc should rise above the surface of the circular table by a maximum of a third of its diameter, otherwise it will not saw the wood properly, and the process itself will become dangerous. If you need to cut a beam with a diameter of, for example, 100 mm, a similar cutter parameter should not exceed 350 mm, however, an engine with a power of 1 kW or more is also required here. For workpieces with a diameter of more than 150 mm, a mini circular made by hand is hardly suitable. On some factory circular machines, a riving knife is provided, which is installed behind the disk at a distance of 2 - 3 mm from the saw teeth. It eliminates the jamming moment due to the closing of the parts of the sawn workpiece, therefore it can be very useful in the case when a home-made circular is assembled.

Side stop adjustable

It is possible to put a high-quality emphasis from a steel corner with a section of about 80 mm, which is 3–4 cm longer than the table structure. The flat sides of the corner are bent down so that their width is one and a half cm more than the thickness of the table. After installation, the stop is fixed on a homemade circular table in a predetermined position with the help of bolts. The adjustment of this element is carried out according to the template placed between it and the cutter.

Shaft

The shaft mounted on the circular is the most critical unit, therefore, only a specialist using special equipment should be engaged in its turning and testing as an assembly with the disk. A pipe product with a carelessly fixed circle is excluded immediately, because the slightest errors in the operation of this element will result in major troubles such as equipment breakdown, damage to the workpiece and injury to the operator. The best solution would be to purchase a finished shaft with a seat for the cutter. It is better to give preference to self-aligning ball bearings with a curved inner surface, otherwise the self-made assembly will quickly collapse and the shaft mounted on a homemade circular will become unusable.

Broadcast

In our case, a V-belt drive would be an ideal option, but it is better to refuse a rigid gear mechanism, since such a homemade product does not guarantee safety. If a nail is suddenly caught in the lumber, the motor rotor will provoke the destruction of the disc, which can lead to injury. If the inner diameter of the belt drive pulleys is small, then slippage will be ensured, and the tensioned belt will serve as a kind of damper. The gear ratio is usually chosen based on the engine speed, always taking into account the allowable number of disk revolutions. The smaller the diameter of the saw blade, the greater the frequency of its rotation, and the cleaner the reworked unit will cut.

Motor

Among home-made devices, the most popular is a circular assembled from an engine from a washing machine. This choice is explained by the fact that its operation scheme is best suited for such purposes. Unlike collector units, which are usually supplied with power tools, the engine from the washing machine runs at lower speeds, which means that it shows longer operation, has increased efficiency and is not so prone to all sorts of clogging. You can also use a three-phase motor, but then additional costs will be required for the purchase of a starting and running capacitor, so it is more economical to get by with a device from a washing machine. Here, in general, and all the wisdom.

A stationary circular saw, made by hand, is a useful and necessary tool in the household, which greatly facilitates the woodworking process. In order to make a circular saw with your own hands, you need to have the necessary tools and materials on hand, as well as be able to work with metal and know the welding business.

Necessary tools and materials

Homemade circular at home can be made in two different designs: stationary and desktop installation. These installations differ from each other only in the height of the frame used in the design of the unit. The choice of bed height for the device depends on the frequency of operation of the installation and the desire of the master. If the saw is rarely used, then it can be made in the desktop version. This design is convenient in that, if necessary, the device is quickly dismantled and free space is freed up. If you plan to use the unit frequently, it is recommended to make a stationary installation option with your own hands.

The design of a stationary installation includes several components, the main of which are a table, a saw blade, an electric drive, an adjustable stop and a shaft.

To construct the fixture, you will need the following materials and tools:

• sheet metal with a thickness of at least 8 mm;
• metal corner 45x45 mm in size;
• electric drive;
• ball bearings;
• manual welding machine;
• wood block;
• a piece of plastic or laminate.

The manufacturing process of a circular saw is greatly facilitated if a drawing of the installation is made in advance.

All installation parameters should be indicated on the drawing. All elements of the unit are manufactured in strict accordance with the previously developed drawing. After the manufacture of all structural elements, the unit is assembled using a welder.

Assembly technology for a stationary installation of a circular

The main part of a homemade circular is a table. The tabletop of this structural element is made using sheet metal. The size of the countertop depends entirely on the desires and preferences of the master. The main requirements for the table are to ensure reliable stability and ease of working with the tool. If installation of additional equipment is required, then the places for its installation can be closed with a sheet of plywood.

When designing and assembling a homemade installation, special attention should be paid to the height of the guide. The most convenient design option is considered to be one in which the guide protrudes 120 mm above the table surface. With such a height, it is possible to process the board both in width and in thickness.

When designing the guide for installation, it is required to use two pieces of metal angle and a clamp that is attached to them by hand welding. Manufacture of the guide from two pieces of the angle prevents its displacement during operation on the unit. A wooden beam and a strip of laminate are attached to the corners with self-tapping screws. The length of the piece of laminate should match the length of the table.

When making a circular saw, the table should be made adjustable in height, which will make the work process more convenient.

To mount the electric drive and the installation shaft, a single platform should be made. The platform is installed on one axis in the form of a rocker arm. Fixation of the platform is carried out using a bolt with a diameter of 15 mm.

On the side of the saw, a metal plate is fixed by welding, in which a hole must be made. It should be oblong in shape along the rocker arm. A lamb with handles is screwed onto the bolt passing through this hole, it is a retainer. When using a 400 mm disc in such a design, it is possible to process boards up to 240 mm wide.

Other options for the design of the circular saw

A circular mini saw can be made in a manual version. When designing such a saw, it is best to use a grinder. To do this, some changes and improvements are made to the design of the tool. An axial handle and a sliding stop should be mounted on the tool body.

To design the stop, you will need two metal corners. Corners are placed on the sides of the saw disk working element, which replaces the disk working element made of abrasive material used in the grinder. The corners are fastened while maintaining a gap of 3-4 mm. The corners in front and behind are connected with bolts and nuts. Washers are used to maintain clearance. The lower edge used in the stop of the corners is rounded off, which prevents the occurrence of catching on the workpieces being processed.

To fix the stop on the body of the grinder, a clamp is fixed. This structural element is made of metal tape. The screed should be placed at the bottom. A strip of galvanized steel with a thickness of at least 1.5 mm is attached to the tape. A hole is made in the strip for the bolt of the sliding stop. Using washers, set the required clearance between the working element and the side of the stop. The gap must be the same on both sides.

An axial handle is attached to the body of the device. For this purpose, the gearbox is disassembled. This is required in order to determine where you can make four holes for small bolts. The handle should be made from a piece of pipe. The handle should be shaped like a bracket, holes for fixing bolts should be made at the ends of the bracket. Under the handle, you need to fix a piece of the rod protruding forward. On the rod, make a hole for the axle with a thickness of 4-6 mm. For ease of use of the device between the rod and the handle, the gap should be at least 100-150 mm.

Then the control rod is made. To construct this element of the device, a rod with a diameter of 4-6 mm is required. The end of the rod is flared, and with the help of washers on the front fastening of the stop, the same gap is set along the entire length. The section of the rod that enters the hole in the handle is threaded. A nut is screwed onto the rod, and after that the rod is attached with a second nut. With the help of nuts, the cut is regulated.

Stationary type circular saws are quite expensive on the market. However, if desired, the model can be made by hand. This will require a standard set of tools. A welding machine is used to install the frame. To fix the saw blade, you need a drill. Before assembling the device, it should be borne in mind that the design of circular saws can vary greatly.

Hand saw model

(stationary) do it yourself from it is quite simple. First of all, you need to assemble the table. For this, metal profiles are used. The ends of the workpieces are connected using a welding inverter. The saw blade is directly attached to the holder. A simple do-it-yourself stationary circular saw is assembled with a small-width pulley.

In some cases, a casing is used to protect the device. The caliper for the circular saw is often of the rack type. Modifications with cam quills are very rare. Collector motors are installed with a power of 3.3 kW. In this case, it is more expedient to make a platform from a steel sheet.

Washing machine devices

Assembling (stationary) with your own hands from the washing machine is quite simple. For this purpose, a motor is taken. it is recommended to select a diameter of up to 30 cm. The pin is used with a crankshaft. Many experts advise installing rails up to 33 cm long. The working plate is placed on the front of the frame. The feed mechanism in this case can not be installed. In order to fix the frame, a metal corner is used. The flange is most often installed behind the caliper. At the end of the work, it is important to fix the flywheel.

Modifications with one stop

Very often, specialists assemble a circular saw with their own hands. Drawings for designs with one stop can be found in a wide variety. Many of them involve the use of cam rests. Experts first of all recommend starting the assembly from the frame. The legs in this case can be made of wooden bars.

After installing the working plate, guides are placed. Above them it is necessary to fix a horizontal shaft. A corner is attached to the edge of the platform, and the casing is rarely used in the design. There are also many models with a drive steady. They differ in large dimensions. The bearing row, as a rule, is installed above the working plate. In some cases, the support is welded near the pin.

Models with multiple stops

With several stops, it is quite difficult to assemble a circular saw with your own hands. The modification drawings indicate the need for a guide pin. The assembly of the model begins with the frame blank. For this, profiles are selected from stainless steel. It is also important to note that the racks can be fixed using a welding inverter.

The work plates are installed last. Sometimes a do-it-yourself circular saw (stationary) is made with a 3 kW commutator motor. A handwheel is used to adjust the position of the steady rest. The bed in this case should be fixed on the racks. A caliper is used to change the position of the platform.

Drawings of the device with an elbow ratchet

A do-it-yourself stationary circular saw is made with a cranked ratchet (photo shown below) using a rack caliper. In some cases, a feed mechanism is used. First of all, when assembling, it is important to install the lower frame. For this, two stainless steel profiles are selected. To install the bearing row, you will need a welding inverter.

It is also used to connect desktop rails. The pin is installed only with a cross member. At the edge of the table is soldered. At this stage of the assembly, it is important to calculate the distance to the saw blade. On average, it is 22 cm. A wooden fence is used to protect the hands. It is important to fix the guides behind the rack. The steady rest is most often installed behind the flange. In order for the flywheel to rotate freely, a small lining is required. It is fixed behind the guides.

It is also important to note that modifications without a caliper are very common. Their pins are used with gearboxes. In order to protect the hands, a small shield is installed. The bed is most often used with sharpened ends. The lunette in the design is fixed on the platform. If we consider simple models, then guides can be used from wood. The collector motor is used for both 3 and 5 kW. The work on assembling the saw ends with the installation of stops.

Dimensions of saws with two steady rests

With two steady rests, it is very easy to assemble a circular saw (stationary) with your own hands. The dimensions of the table in this case depend on the diameter of the saw blade. The width of the platform, as a rule, does not exceed 35 cm. In order to assemble the modification, the frame is placed first. Metal profiles are selected by 3.4 cm. The pins are mainly installed behind the steady rests.

In some cases, the beds are placed on two stops. The quill is used with a worm gear. If we consider large-sized modifications, then they use wide racks. It is also important to note that it is more expedient to set the lower block at 56 cm. A rotary handwheel is used to adjust the steady rest. Directly the saw blade is placed behind the caliper.

Modifications of the TS 820 series

You can make a saw of this series yourself. For this purpose, the frame is set to a width of 34 cm. The corner for the stop is easiest to make from a metal profile. The bearing row is attached to the rack with screws. Many experts advise to install the lunette last. The guides for the saw are selected by 34 cm.

The handkerchief is easiest to make from a wide bar. The collector motor is installed on the saw with a power of 3 kW. The gearbox is attached to a rack on the platform. The saw blade is fixed with the drive shaft. The support for the normal operation of the modification should be rigidly fixed. Barriers can be used to protect hands.

How to make a model like TS 825?

With tools, this circular saw is easily made stationary with your own hands. Drawings for this design can be found in a wide variety. However, the most common are schemes for two lunettes. The bearing row in this case is installed behind the cross member. not a lot of power is selected. The pin should be installed in the central part of the working platform.

In this case, the feed mechanism is not required. In order to fix the plate, a metal corner is used. Saw guides are used at a low height. For free movement of the steady rest, a flywheel with a rotary mechanism is used. The bottom block must be well protected. It is also important to pay special attention to the installation of the frame. Legs for construction can be made from ordinary bars. Directly the saw blade is placed near the central rack.

Assembling the GKS 190 Series

This do-it-yourself circular (stationary) saw is assembled only with the help of a 4 kW collector motor. The bearing row can be installed behind the rack. For this purpose, a small flywheel is used. It is also important to note that the pulley is allowed to be used at 5.6 cm. The gearbox is most often installed behind the steady rest. All this is necessary for the free rotation of the shaft. The bed in this case is easiest to make from bars. It is more expedient to select racks of small width.

The flange is usually installed at the edge of the platform. In this case, the drive shaft must not come into contact with the guides. The fencing tape is most often mounted behind the front pillar. The width of the platform should not exceed 68 cm. The shield is easiest to install with screws. However, it must be at a safe distance from the gearbox. Particular attention should be paid to the lower supports. To increase stabilization, it is recommended to use only wide profiles. The height of the support in this case should not exceed 30 cm.

Modifications of the GKS 156 series

This circular saw (stationary) is hard to assemble with your own hands. First of all, it is important to note that the motor will be required for 4 kW. Many experts in this case advise using only steel guides. They should be installed behind the front pillar. The armrest is most often made from a bar. It is also important to note that the design will require a wide emphasis.

It is more expedient to install the shield near the rear support. The bearing row is mounted together with the rack. At this stage of work, it is important to calculate the exact distance to the saw blade. The minimum gap is allowed at 3 cm. The bed is most often used on four legs. In order to install the guides, a welding inverter is used. The lower block is mounted under the gearbox. It is important to fix the lunette securely, and in this case a ratchet is not required.

How to make a model like GKS 144?

The indicated circular saw (stationary) is assembled with its own hands on a motor with a power of 2.2 kW, and the bed is selected by 40 cm. The bearing row is fixed in front of the rack. Guides are easiest to use with small widths. It is also important to note that one flywheel is required to assemble the device. It must be attached to the swivel mechanism. It is more expedient to make a shield from a steel sheet. The casing in this case is not required. Directly the legs can be installed around the corner. The lunette for the saw is selected not of a large width. The carrier plate is fixed last.

Assembling the K-CS 1300 Series

The indicated circular saw (stationary) is assembled quite simply with your own hands. The bed for the model is used at 34 cm. In this case, the bearing row is installed behind the rack. Directly the saw blade is placed after fixing the guides. Particular attention should be paid to the collector motor. In this case, its power must be at least 4 kW.

The flange is used with a steel plate. It is more expedient to install the armrest behind the front pillar. For this purpose, two holes are made on the working platform. It is important to fix the lunette near the motor. The saw blade guard does not need to be installed. The lower block should immediately be selected not of great height. It is more expedient to use a support with the roller mechanism.

Modifications of the K-CS 1325 series

Devices of this series are assembled using 3 kW collector motors. If you believe the experts, then handcuffs are best used from wood. It is also important to note that the caliper should be installed on top of the workpiece. The ratchet in this case is not installed on the saw. The gearbox is used with one bracket.

Do-it-yourself circular saw is easy to assemble. Homemade devices are often found in the workshops of people with the necessary skills to work with tools.

All actions during manufacture must be carried out carefully, observing safety regulations.

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

Assembly order

A homemade circular saw with your own hands can be easily assembled 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 (need to be assembled);
• axial handle (need to be done).

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

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

Parts are fastened at the back and front with transverse ligaments using nuts and bolts.

The assembly scheme of the stop is not complicated. A metal collar is put on the body, the screed of which is produced from the bottom of the device.

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

Threaded holes are drilled in the gearbox of the apparatus, 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 the subsequent attachment of the axle handle. If a handle located on the side of an ordinary grinder is used, then it will be quite difficult to make a hole.

The next step is the manufacture of the handle. The part can be built using a rod bent upwards or a tube made of metal. Its ends will be further attached to the gearbox.

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

Using a lining of washers under the front of the stop, equalize the gap parameters over the entire duration of the circular saw.

If a 0.6 cm rod is used, then thin washers will be needed. A thread is applied to the back of the rod.

Then the part is placed in the recess on the handle. Now the device is ready for use.

When using a circular saw, you must follow the safety rules, especially you can not drink alcoholic beverages, as their use 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, choose the design and follow the drawings and instructions exactly.

A table saw is easy to assemble from a regular saw. The finished device will have a compact size.

To perform this work, it is necessary to assemble a frame from a thin tube or twig 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 device stand must be stable. Rocking the saw during operation can be very dangerous, because any careless movement can lead to the loss of fingers or hands.

It is best to make your table out of metal, fixing 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 spin freely.

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

A do-it-yourself homemade mini circular saw is attracted and fixed with clamps to the vertical extreme part.

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

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

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

But in order to assemble the device with your own hands, special skills are needed. If there is no necessary skill, then it is better to purchase a circular electric saw, in the correct, reliable and safe operation of which you can be absolutely sure.

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

How to assemble a stationary device?

Having learned how to make a circular saw, they begin to assemble the apparatus. A stationary saw differs from a mini tool only in the size of the statin.

The statin should have a base of sufficient width without distortion, with a cutout for the 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 of the circular saw is also attached to the base.

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

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

It is covered with a tin or steel sheet, as the wood that passes while working on plastic and wood gradually forms furrows in the coating. Because of the holes and recesses, it will be very difficult to make a quality saw cut.

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

For unhindered sliding along the edges without changing the desired angle, a sled is 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 life-threatening.

But even a minimal protrusion of the cutting element can cause serious injury 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 cut with a home-made machine.

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

Then a stop is put on the table surface, which is fixed with bolts. The stop is set according to special measurements, pre-installed between the working part of the device and it.

A do-it-yourself circular saw is an excellent tool that allows you to solve a large number of household and other tasks. In fact, it is not difficult to make this device on your own even if you do not have any special skills, the most important thing is to understand at least a little the principle of processing metal alloys.

The materials needed for the job can be found in the home workshop or in the garage. So, do-it-yourself circular saw made from the following elements:

• corner made of strong steel;
• rectangular profile pipe;
• engine.

The finished circular saw can be placed on a workbench. If you do not have it, you will have to make a table yourself. The engine can be taken from an old walk-behind tractor or a washing machine.

Circular from an angle grinder

If you have your own "Bulgarian", This is 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 pieces of steel angle placed on the sides of the saw blade. With the help of nuts and bolts, they are connected by a transverse ligament, and the gap between the working part and the sidewalls of the structure will be provided by washers.

On the "grinder" you need to pre-tighten the metal band clamp with a screw tie down. Then you need to attach the folded metal strip in half to the holes for the sliding stop. The post and collar 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 “regular” 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 a horn or staple. 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 bar that will regulate the process. For this purpose, you need to take a piece of a metal rod, make a loop from one of its ends, rivet it slightly and make a hole for the front stop bolt.

From the other end of the rod you need to make a thread, which 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. Lowering and tightening them, you can adjust the depth of cut. By the way, if you use a drill instead of a grinder, you can make a similar tool.

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

Compact desktop machine

Above we talked about how to assemble a manual circular. Now we will tell you how to turn this device into a stationary one. This process involves the manufacture of a U-shaped frame from a pipe, as well as the installation of a transverse arm. The lower ends of the structure must be bent horizontally in the direction of the cut. They are bolted to the table. Stability is provided by additional supports.

Lever mobility is provided by cutting a horizontal segment into two identical parts, which are fixed to each other with clamps. The cutting disc is attached to the vertical element of the bed with clamps.

Stationary installation

A machine that looks like factory models needs a competent attitude during the assembly process, so you need to take care of all the little things in advance. The desktop version of the "circular" differs from the stationary one only in the height of the bed, which is determined by the features of the work and the size of future workpieces. One-time processing can also be done using an ordinary table saw, which after work can be easily removed to a pantry or barn. But the master, who constantly deals with wood, will need a stationary installation. Therefore, he needs to make a table for a circular saw with his own hands.

The circular saw has the following advantages:

• Such equipment allows you to make better and deeper cuts.
• The machine is much more convenient than manual equipment.

From the foregoing, we can conclude that self-made circular saws have a completely understandable and simple design, and the drawings that can be found on the World Wide Web will greatly simplify the process of assembling equipment. Before self-production of the "circular", you should separately consider all the necessary elements in order to understand the nuances of the functioning and installation of home-made equipment.
