How to make a machine from a circular saw. How to make a circular saw from a circular saw with your own hands

The circular saw is a convenient and productive tool that is present in the workshop of every real man. If you work with lumber in large volumes, then you will need to do it for a circular saw.

Of course, you can make an individual order in a furniture company. But you can build such a table on your own, having the necessary drawings, materials and tools.

Design The table consists of only two elements:

If desired, the craftsmen can add the product:

• drawers;
• racks.

Important: the circular saw is mounted under the table, only its disk is located on the table top. The hole for the saw should be slightly larger than the blade. Thus, sawdust will not clog the mechanism.

Such a piece of furniture should be strong enough and reliable. Keep in mind, the greater the power of the saw, the higher the load on the table surface will be.

TO benefits homemade table for a circular saw, you can also add:

• comfort and convenience in work;
• saving money;
• high labor productivity;
• the ability to make a product based on personal needs and characteristics of the workshop.

Material

You can make a circulation table on your own from different materials. The most common are considered:

• or chipboard;

Each individual option has its own merits. Chipboard, plywood and MDF are easy and simple to work with. In addition, these lumber are available at an affordable cost. But products made of wood have higher strength and technical characteristics.

Attention: before proceeding with the assembly of the product, all its wooden elements are treated with antiseptic compounds.

Drawing and dimensions

Before starting work, it is recommended to make a drawing of the product. On it, indicate all dimensions, materials of manufacture and other important information. You can make a high-quality drawing of any piece of furniture using special computer programs..

When drawing a table, be sure to consider the size of the circular saw. Each brand of tool will have a specific size.

If during the workflow you like to leave materials on the table, then tabletop dimensions must be at least 120 by 120 cm.

Tools

To make a practical and comfortable table, you will need different tools and materials:

• lumber (plywood, chipboard, MDF and others);
• boards for legs;
• furniture glue;
• paints and varnishes;
• self-tapping screws;
• drill;
• milling cutter;
• electric jigsaw;
• circular saw;
• Ruler and pencil.

How to make a table for a manual circular?

The manufacture and assembly of a table for a circular saw is divided into certain stages:

Finishing

After the manufacture and assembly of the circulation table, to simplify working moments, on the table it is desirable to mark. It is she who will help facilitate the cutting of materials.

To extend the life of the product and increase its aesthetics, a do-it-yourself table can be primed and varnished. These manipulations will also prevent the lumber from sliding on the surface and protect the product from high moisture.

Safety in use

Keep in mind that working with a circular saw is a dangerous business. To avoid injury during the work process, it is necessary to constantly monitor the position of the saw table, its strength and stability.

Each time before switching on the equipment, check that it is securely in place.

Attention: It is strictly forbidden to hold the cut material with your hands while the saw is running. Otherwise, your fingers may be damaged.

To prevent bouncing wood particles from getting into your eyes, work recommended with protective goggles.

Conclusion

In conclusion, it is worth noting that making a table for a circular saw on your own is not so difficult. And its presence will greatly simplify and even expand the functionality of using a circular saw.

In contact with

A circular saw is an important and necessary tool for many people, allowing them to independently engage in numerous types of housework. It has a fairly high cost, so many people think about how to make it on their own. To do this, you need to prepare a workbench or table of the optimal size that replaces this tool, and you also need to have the ability to work with metal. During the process, you should be careful and careful so as not to harm yourself, as well as to get the perfect result of the work.

Do-it-yourself circular is made using the following components:

• rectangular profile pipe;
• corners formed from steel;
• engine.

How to make a hand saw from a grinder?

A home-made circular saw from a circular saw with your own hands is considered quite popular. Most often, a grinder is used for this work. To do this, only some changes are made with a ready-made tool, which is equipped with a special sliding stop, and an axial handle is also installed.

All work on the independent creation of a circular saw from a grinder consists of the following steps:

• A sliding stop is created on the tool, represented by two corners of small dimensions made of metal. They are installed on both sides of the main working body of the tool, represented by a disc with different teeth, used instead of a standard abrasive wheel. At the same time, a gap of 4 mm is left on each side.
• So that the installed corners do not cling to the part being processed during the use of the finished saw, they must be slightly rounded from below. Front and rear, they are connected by special cross-links, for which standard fasteners are used - bolts and nuts.
• A special collar is attached to the angle grinder itself, made of a tape formed from metal. At the same time, its screw tie should be at the bottom of the tool. A strip of tin is fixed to this clamp, folded in half in advance, and it can be replaced with galvanized. This element must have a special hole designed to fix the rear bolt of the sliding stop.
• Identical gaps are created between the stop of the future circular saw and its working body.
• In the gearbox housing, which is an important element of the grinder, from 2 to 4 threaded holes are created. They are designed to use small bolts. For this work, the gearbox is initially disassembled in order to determine exactly where it is possible to create holes in its body with a drill. It is with their help that the axial handle is fixed, which can be bought ready-made or made on your own.
• If it is supposed to perform the axial handle on its own, then a metal tube is used for this, and a metal bar can also be used, which has an unusual curved shape. In the created handle, as well as in the gearbox housing, holes for fastening are formed, after which the fixation itself is realized.
• Next, an adjusting rod is created, for which a small piece of a steel bar is usually used, and its thickness is usually 5 mm. One end of this segment is bent, resulting in a loop. A hole is created for the front stop bolt. Washers are selected on the front of the stop, which will allow you to get a uniform and optimal gap in width. On the other side of the rod, a thread is formed that enters the hole on the saw handle. To do this, a nut is screwed onto this hole in advance, and as soon as the assembly is completed, the second nut is also screwed on. With these nuts, which are easy to tighten or loosen, the optimal and desired depth of cut is ensured.

Thus, the process of creating a manual circular stove is considered quite simple. Here you do not need to use expensive tools and materials, and all work is easily implemented on your own.

How to make a desktop circulation stove?

You can even make a circular table with your own hands with drawings that are formed in advance, and are also high quality and correct. With their help, you can get a design that has high quality, safety of use and efficiency.

A full-fledged circular saw, formed on its own, is represented by a serious, complex and unusual design, which is created only with preliminary consideration of all its elements, study of drawings and preparation of materials and tools.

It is important to decide whether the circular will be stationary or desktop, and the choice depends on how often the tool will be used, as well as what scale of work is supposed to be implemented with it.

The design of a standard circular saw

"Real" stationary circular

A do-it-yourself circular table, the drawings of which are freely available, is created easily and quickly if you know its design well. If all the components are separately formed and prepared, the result is that they are simply securely and firmly connected to each other, providing an optimal design.

The main elements of this equipment include:

• Table. Usually it is covered with a sheet made of galvanized steel or tin. It is not allowed to use plastic or wood for these purposes, since these materials will not be able to withstand the significant impact of other materials, therefore they will be rubbed, resulting in deformations, bends and holes.
• Cross links. They are created for the table, and usually a steel corner is used for these purposes, the thickness of which is approximately 7 cm. These connections are equipped with a shelf attached to the outside in a horizontal position. In this case, the ease of forming the side limiter is ensured.
• The working body of the circular saw. It is represented by a toothed disc that protrudes beyond the table, as this provides a good sawing process for various elements.
• Motor equipment, which must be powerful enough. Its choice depends on the diameter of the saw. If it is supposed to work with lumber whose thickness exceeds 15 cm, then a very powerful motor is selected, therefore the process of creating a circular will be quite difficult, since it is difficult to find this element in the public domain.
• Side stop. It is made adjustable, and an even piece of a corner of steel is used to create it, the thickness of which is approximately 7 cm. This stop in length should be approximately 35 cm longer than the length of the table. One vertical shelf on each side is cut off, so it turns out to be equal to the length of the table . The tails, which are flat, curve down. Holes for threading are formed in their lower shelves. The emphasis is attached to the table with bolts, and it is set exactly according to the template.
• Shaft. It is an important piece of equipment, and it is desirable to purchase it in finished form so that it has high quality and reliability. Usually, the finished element has a special seat designed for the future saw blade.
• Bearings. They can be different, but self-aligning elements that are ball-shaped are considered the best choice. They are equipped with a double row of special balls. Inside the clip in the section is curvilinear. If you use cheap and low-quality bearings in a homemade circular, they will not last too long. The trunnions are equipped with covers that prevent sawdust from entering the bearings.
• Saw transfer. A V-belt design is usually chosen, since if a gear is chosen, it is considered dangerous enough for amateur use. This is due to the fact that if lumber is used that has previously been used for other purposes, then a nail or other fastener may get caught in it, which, when it enters the gear, can cause the engine disk to simply fly apart.
• Gear ratio. It is selected depending on the parameters of the engine, namely on its revolutions and on the frequency of rotation of the disk.
• Engine. It is best to choose an asynchronous motor that is single-phase. Typically, standard washing machines are equipped with such elements. They are ideal for a homemade circular saw. It is not advisable to use collector motors, which are usually installed in various electrical appliances, since they give extremely significant speeds, and also cannot run for too long, which is considered important for a circular.
• A three-phase motor is often used, but it is complemented by a starting and running capacitor, which are equipped with fittings. They have a significant value, and they must be either oil-paper or just paper.
• An engine starting circuit that can be used for a delta or a star, and it should not need additional refinement.

Thus, the process of creating a circular saw on your own is considered quite complicated, but if you know what basic elements the equipment consists of, as well as choose high-quality elements that are reliably and safely connected to each other, then the work will be done correctly on your own.

A hand-held circular saw is a powerful tool with high productivity. One of the main advantages of a circular saw is that maneuverability becomes a disadvantage when large volumes of wood need to be cut. To simplify the process, you can easily compile .

Table device

The design of a table for a manual circular saw is so simple that most craftsmen make it without preliminary drawings and diagrams. This is a sturdy workbench that is made from wood and plywood. The most reliable table bases are made of metal. They are the heaviest and require the skills of a welder. Therefore, more often coasters are made from lumber waste. A circular saw is attached under the tabletop, the disk protrudes above it through a specially made slot. Timber is moved along the countertop and sawn with a rotating disc. For convenience and accuracy of work, the table is equipped with additional devices: angular and longitudinal emphasis.

The tabletop "eats" part of the working surface of the disc, the depth of cut will decrease by the thickness of the tabletop. Therefore, it is desirable to select a circular saw with a maximum disc diameter, and a thin but rigid tabletop.

If the saw has not yet been purchased, select models with high power (from 1200 W). They can cut through large volumes of wood. Holes will be drilled in the sole for fastening: the molded base may crack. Therefore, it is advisable to choose a tool with a stamped sole.

Selection of materials

To make a good stand for a hand-held circular saw, you should remember carpentry skills, be patient and a small amount of materials:

• laminated plywood 15 - 20 mm;
• timber 50 x 50;
• board;
• switch;
• external socket;
• piece of electrical cable;
• PVA glue;
• wood varnish (if the plywood is not laminated);
• self-tapping screws.

And tools:

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

The size of the countertop will depend on the area of ​​​​the workshop. However, on a table that is too small, it will be inconvenient to cut long pieces. If the entire part fits on the work surface, the cut is smoother and more accurate. The height of the legs is selected depending on the height of the master.

For a small workshop, a desktop design with approximate dimensions of 50 x 50 x 25 cm is convenient.

Table making process

1. From a sheet of laminated plywood, we cut out the countertop of the required size. The marking is applied to the lower plane using a metal ruler and a pencil. We cut the plywood with an electric jigsaw, mill the edges if necessary. If the plywood is not laminated, we clean the surface of the table with sandpaper.
2. We turn over and from the bottom we make markings for attaching a manual circular. To do this, remove the disc from the tool and set it with the sole in the desired place. We make marks on the table top and on the sole for fasteners and a groove for the saw blade. We drill holes for the bolts. They will be screwed from above, through the countertop and from below held by nuts. Therefore, from the side of the working surface, we countersink the holes, and grind the bolt heads so that they do not protrude.
3. If you plan to cut the material at different angles, the slot for the saw blade is made in the form of an inverted trapezoid. For even sawing, a regular groove is made. Before cutting the slot and holes for fasteners, attach a saw, correct the marks, and only then cut.
4. Mark with a pencil the location of the stiffeners. They are made from a board and installed from below 8 - 9 cm from the edge of the countertop. We will attach the legs of the table to the ribs. The ribs are fixed with self-tapping screws at intervals of 15 - 25 centimeters, additionally glued with PVA. Self-tapping screws are screwed in from above, through the countertop, the heads are completely recessed. The ribs are fastened together with long self-tapping screws.
5. The legs of the table are made of a bar or board, their length will be from 100 to 113 cm. The legs, slightly diverging downwards, will give greater stability. They are fixed on large bolts, twisted from the outside, fastened with nuts from the inside. Screeds from a bar will additionally strengthen the frame.
6. To adjust the height of the table, nuts are attached from below, into which M14 bolts are screwed.
7. Now you can fix the saw from below by passing the disc into the prepared slot.
8. We attach an electrical outlet to the inside of the table, pass an electrical wire from it and install the switch in a convenient place (on the outer part of the stiffener). The outlet will be powered by the switch. From it we stretch the wire to the nearest power source in the workshop. Using a construction tie, we fix the ON-OFF button on the body of the circular saw in a recessed position.

Let's start making auxiliary stops. For the longitudinal stop, you will need a #30 aluminum square tube and two screws with wing nuts.

1. We saw off a piece of pipe along the length of the countertop, cut holes for the screws 3 cm from the edge.
2. We cut out two clamps from pieces of plywood. The structure is ready.
3. For sawing across the table, we make a plywood sled. We align them relative to the edges of the table, press and move along the jagged circle. In the place where the circle passes in the sled, we cut a groove. Small parts can be stacked directly inside the sled and sawed.

Dust removal is organized from under the table, but most of the dust scatters from above, so it’s a good idea to supplement the device with an upper dust outlet.

Working with a circular saw is very dangerous, so care must be taken to protect your fingers. Cut out a pusher from a piece of board or furniture board.

Additions to the design

This design can be supplemented with a riving knife, which will be removed. Put on a disc protection on it, which cuts off the flow of chips flying directly into the carpenter.

Some masters, assembling a table according to unique drawings, completely remove the factory protective cover, and replace the factory platform with a home-made one. If you do not plan to cut at an angle, you can also remove all devices for adjusting the blade tilt. The saw is fixed directly on the new base, which allows you to gain a few millimeters of cutting depth.

- a necessary and useful tool in the arsenal of a home master. It is especially necessary for those who work a lot with wood. To make a circular saw on your own, it is enough to have a great desire, the necessary tools and be able to work with metal.

Serious tool

A do-it-yourself circular saw can be a stationary or desktop model. In essence, they are one and the same. The devices differ only in the height of the frame. What height to do will depend on the intensity of use of the workplace. If the saw is rarely used, then it can be made in the desktop version. If necessary, the structure can be dismantled and make room in the workshop for other work. If the master constantly works with wood, then a stationary circular saw is more suitable for him.

The stationary structure consists of several main components: a table, a toothed disk, an engine, an adjustable side stop and a shaft.

For its manufacture will be needed:

1. A sheet of metal with a thickness of at least 8 mm.
2. Metal corner 45x45 mm.
3. Electric motor.
4. Metal disc with teeth (diameter 400 mm).
5. Ball bearings.
6. Welding machine.
7. Wooden block.
8. A piece of plastic or laminate.

It will be much easier to make a circular saw with your own hands if you first draw up a drawing of the future design and indicate all the necessary dimensions. All parts are made in accordance with the drawing, and then assembled into a frame using a welding machine.

Assembly of a stationary structure

The main part of the saw is the table. The tabletop must be made of sheet metal. Its dimensions depend on the preferences of the master. The main thing is that the circular saw with your own hands is stable and it is convenient to work on it. If additional space is required for installing other fixtures, then the surface can be covered with a sheet of thick plywood (Fig. 1).

Particular attention must be paid to the height of the guide. It is most convenient when the guide protrudes 120 mm above the table. As experience shows, with this arrangement, it becomes possible to process boards not only in width, but also in thickness.

Figure 1. A sheet of thick plywood is great for covering the countertop surface to install additional fixtures.

To make a guide for a circular saw, you will need 2 pieces of a metal corner and a clamp that is welded to them. The metal part is intentionally made from two parts of the corner. A solid corner will lead when the saw is working. Using bolts and self-tapping screws, you need to fasten a wooden block to the corners, and fix a piece of plastic or laminate 120 mm wide on it. The length of the piece of laminate should correspond to the length of the table. This part should be exposed at an angle of 90 ° relative to the tabletop (Fig. 2).

A do-it-yourself circular saw must be height adjustable. In some designs, you can adjust the table, but it is more convenient for work when you can raise and lower the saw itself.

A single platform is required to install the motor and shaft. It should be installed on one axis in the form of a rocker arm. It is fixed with a piece of bolt with a diameter of 15 mm, which is welded to it. A metal plate must be welded on the side of the saw, in which a hole must first be made. Its shape should be oblong along the rocker arm. A bolt will pass through it, onto which a lamb with handles should be screwed. The saw clamp is ready. If it becomes necessary to adjust the height, then the lamb is unscrewed, the saw is set along the ruler and the lamb is twisted back. When using a disc with a diameter of 400 mm, boards up to 240 mm wide can be processed (Fig. 3).

Make other options

Figure 2. A piece of laminate should be attached to a wooden block, the angle of which should be 90 ° relative to the tabletop.

A do-it-yourself circular saw can be made in a manual version. The easiest way is to make it from a grinder, making some improvements to its design. On the grinder, you need to install an axial handle and a sliding stop.

To make a sliding stop, 2 pieces of a corner will be needed. They are located on the sides of the disk with teeth, which replaces the abrasive wheel. Corners are attached with a gap of 3-4 mm. Front and rear they are connected with bolts and nuts. Washers must be used to obtain clearance. The bottom edge of the corners must be rounded. Thanks to this, they will not cling to the processed objects.

A do-it-yourself circular saw from a grinder is equipped with a sliding stop. A clamp is attached to the body. It is made from metal tape. Its tie should be located below. A galvanized strip with a thickness of at least 1-1.5 mm is attached to the tape, on which you first need to make a hole for the sliding stop bolt. With the help of washers, gaps are established between the working part and the side parts of the stop. The gaps must be the same size.

An axial handle is attached to the gearbox housing. To do this, the gearbox is disassembled so that you can determine at what points to make 4 holes for small bolts. The handle is made from a piece of pipe or rod and must be in the form of a bracket. Its width is slightly wider than the master's palm. At the ends with which it will be attached to the gearbox, it is necessary to drill holes for the bolts. It is not worth flaring the ends of the tube so that the handle does not bend during operation.

A piece of rod or tube protruding forward should be fixed under the handle. Flare the end of the tube and make a hole for the axle with a thickness of 4-6 mm. The hole should be 4 mm larger. To make it convenient to work, a gap of at least 100-150 mm is left between the rod and the handle.

Figure 3. Scheme of a disk for a circular.

The next step is the manufacture of the adjusting rod. This will require a piece of rod with a diameter of 4-6 mm. The end of the pipe is bent in the form of a loop, slightly flared. Using washers at the front end of the stop, the same gap is set along the entire length.

The part of the rod that will fit into the hole on the handle must be threaded. Before inserting the rod, screw the nut onto it. Another nut is screwed on after assembly. Nuts will provide adjustment of the depth of cut. If necessary, they need to be released or tightened.

The main component of a carpentry home workshop is a circular saw. It is intended for primary processing of materials by manual or automated method. Due to the high cost of factory equipment, craftsmen most often come to the conclusion that it is best to make this machine with their own hands.

Requirements for household circular machines

Structurally, it should not differ from factory models. They consist of a support table, in the center of which there is a slot for a saw blade. In addition, the design contains measuring components, elements for fixing the workpiece and for ensuring the safety of work.

Before manufacturing, it is necessary to familiarize yourself with the basic requirements for its components. It is important that they fit each other not only structurally, but also in terms of technical parameters. To do this, you can take a diagram of a typical design of a factory woodworking machine.

Complete set of woodworking saw equipment:

• table. Must have sufficient stability, the surface of the countertop is perfectly flat;
• power point. The main parameters of the electric motor for rotating the disk are power and number of revolutions;
• additional components. These include stops for fixing a wooden workpiece, rulers for measuring.

The advantage of home-made models is the ability to choose its dimensions, performance and other technical parameters. In the process of drawing up a manufacturing scheme, you can choose the optimal height of the table, the dimensions of the tabletop, and the characteristics of the electric motor. This does not have a hand tool for woodworking.

Requirements for woodworking discs directly depend on the parameters of the workpiece, the type of wood and the required productivity speed. This is calculated on an individual basis.

Materials for the manufacture of a circular machine

After drawing up the optimal drawing for the manufacture of stationary equipment with your own hands, you need to select consumables. To do this, you can purchase rolled metal or use existing components.

The main problem is the choice of the power unit. Some recommend installing a factory-made hand saw. However, often they do not have the necessary power to process large volumes of wood. In addition, the limitation on the diameter of the disk will reduce the functionality of the equipment. Therefore, it is best to choose drawings in which there are two separate blocks - an electric motor and a shaft for mounting the disk.

The connection of the load-bearing elements of the desktop is carried out by do-it-yourself welding. Mechanical components will not provide a proper indicator of reliability, as backlash will form due to constant vibration.

• table. For legs, you can use steel corners 30 * 30 or 40 * 40 mm;
• countertop. It is made of dense chipboard, although experts consider the use of a steel sheet to be the best option. In this case, a lattice structure is made in the upper part of the table;
• electric motor. You can use any household model of a 220 V asynchronous power plant, the power of which does not exceed 1.5 kW, and the maximum number of revolutions is 2400 rpm .;
• a system of pulleys for transmitting torque on a shaft with a disk. Pulleys are best taken from the factory. A tensioning system must be provided.

To fix the workpiece along the length, it is necessary to provide a support bar. It should shift relative to the plane of the disk, thereby adjusting the width of the board being processed with its own hands.

Before welding, all steel blanks must be cleaned of rust. Painting is carried out only after the final manufacture of the saw machine with your own hands.

Assembling a homemade circular machine

After preparing the components, you can begin to assemble the structure on wood. Drawings are drawn up in advance, on which all the parameters of the elements are indicated: dimensions, welding places, mandatory processing zones.

First, the frame of the saw machine is assembled with your own hands. It is necessary to provide places for mounting the shaft with the disk and the electric motor. Pulleys should be located on the outside. This is necessary for the periodic tightening of the transmission belts and the prompt implementation of repairs.

According to the diagram, a slot is made in the center of the tabletop through which the disk will pass. The edges of the material must be processed, but the countertop must be even. The plane of the disc must be strictly perpendicular to the surface of the table. Recommended slot dimensions: width - up to 5 cm; length - up to 400 mm.

The motor control unit is located in front of the cutting area. This will help prevent chips from getting into electrical components.
